• 0:00Steven Bartlett?

  So in this part of the conversation, I want to talk about exercise, nutrition, fasting, lifestyle, sleep, environmental factors. And the first question is, why does muscle matter as a woman in particular?

• 0:09Dr. Vonda Wright?

  Muscle matters because it helps your brain produce more neurons. And that's super important for brain health.

• 0:16Dr. Mary Claire Haver?

  As far as protection as we age, it's directly correlative to the amount of muscle that we have.

• 0:21Dr Natalie Crawford?

  And if you have something like PCOS or endometriosis, it's even more important for you because building muscle is going to fight insulin resistance and inflammation.

• 0:29Steven Bartlett?

  I've got two questions to add. Should women exercise differently across the menstrual cycle? And what is the reason why women hear what you guys say and they don't do it?

• 0:38Dr Natalie Crawford?

  I'm so glad we're having this conversation.

• 0:40Speaker 04

  We're back with the leading voices in women's health to unlock the specific insights, data and tools needed to combat the growing challenges women face throughout their lives.

• 0:49Dr. Stacy Sims?

  For women, forever it was all about aesthetics. I'm healthy, I'm thin. Because they are under the assumption through sociocultural ideas that a woman is coming to the gym to lose weight, not to get strong, not to gain muscle. But what we've ended up with is an epidemic of osteoporosis and frailty, really dementia.

• 1:05Dr. Vonda Wright?

  Where 40 to 50% of women will have low bone density, 70% of all hip fractures happen in women. And when you have that, 30% of the time, you have a chance of dying in one year.

• 1:15Dr Natalie Crawford?

  Because most of it is based on male data. And I see a large number of women trying their hardest to be healthy, but what they are choosing to do is actually having a negative impact on their hormonal health.

• 1:25Dr. Stacy Sims?

  And it's not your fault. And this is where we have to educate.

• 1:28Dr. Vonda Wright?

  And it starts now.

• 1:30Steven Bartlett?

  This brings me to questions from the audience, like, what's the best and healthiest way to lose weight? Is there a diet for fertility? Should women ask, is there a link between environmental toxins and early menopause?

• 1:39Dr Natalie Crawford?

  We think so.

• 1:40Steven Bartlett?

  But also, if you were to design perfect workout regimes for menopause, for perimenopause, what would you... Oh, Stacey's clapping. Go ahead.

• 1:52Steven Bartlett?

  This is part two of my conversation with four of the world's leading experts in women's health. And in this episode, we go even deeper into actionable, practical things you can do to improve your health. And by the way, if you're a man and you've been sent this episode by a girlfriend, a wife, a daughter, whoever it might be, I know you might not think this conversation's for you, but more than 50% of this planet are women. You have a tremendous advantage in your relationships, at work, and just being a human being going through life, if you understand the majority of the population. And for so long, women's health, women's bodies, women's anatomy, their psychology and physiology, has been a mystery, because there hasn't been the same amount of scientific research done to understand

• 2:36Steven Bartlett?

  them. So in this conversation, we're going to demystify all of that, so that you can understand your wife, your partner, your daughter, your colleague, your mother, your grandmother, even better.

• 2:50Steven Bartlett?

  So in this part of the conversation, I want to talk about exercise, nutrition, fasting, lifestyle, sleep, environmental factors, and all the things that we kind of alluded to when we were referencing hormones and menopause, but in a more actionable sense. And I guess the first question is similar to the first question in part one, which is, why does it matter for us to have a conversation about women in this context versus fitness generally or nutrition generally?

• 3:14Dr. Stacy Sims?

  Sport and exercise science in itself is a small subset of like sports medicine and medical research. And most of the research has been done on men. So if we look inherently at most of the recommendations of exercise, recovery, nutrition, it's based on male data. And we established earlier that that's not generalizable. So when we really want to get into the nuances of how do we create an adaptive stress for women, we have to look at it differently. We look through the female lens, understand the female physiology, and acutely how hormones can affect adaptations, and how women respond to different environmental cues than men.

• 3:53Dr. Stacy Sims?

  Yeah, our hormones distinctly control a lot of our environment and the our other cells that are not what we think of as our hormone cells work with our hormones. So if we think about the gut, we think about the liver, our immune system, a lot of this is so hormonally derived, but it's a two-way street, meaning your hormones influence what is happening in your gut, but your gut influences what is happening in your hormones. And because women have different hormones than men, as far as what's predominant and when they are, we have to come at this and approach it a different way.

• 4:25Dr. Mary Claire Haver?

  There's so much to do with messaging that women receive as far as their health goes, and this, you know, be small at any cost, you know, you know, get to that number on the scale. And I see it on social media that the conversation is changing, hopefully, you know, GLP-1s is tampering this a little bit, but strong over skinny, nutrition over calories, like we are trying to build bigger, stronger bodies and take up more space, is the message that needs to have. I mean, forever, it was all about aesthetics. You have to look young, feel young, be young, anti-age, you know, all those things. And what we've ended up with now is an epidemic of osteoporosis and frailty and really dementia.

• 5:07Steven Bartlett?

  Should women exercise differently across the menstrual cycle?

• 5:11Dr. Stacy Sims?

  So this is the nuance. And this is something, if you'd asked me maybe five years ago, I would have said, sure, from a molecular level, we see that there are certain things that happen with estrogen being in isolation for the most part. And then when you have estrogen and progesterone, we see their metabolic shifts, we see their temperature shifts. But the caveat is, we don't know if a woman ovulates or not. And I'm sure that Natalie can, you know, give some stats about the an-ovulatory incidences in most women. If we were to understand and know when a woman ovulates, in addition to how she feels across her cycle, then she can individually tailor her menstrual cycle to her training. But for general plan, we can't do that.

• 5:57Dr Natalie Crawford?

  I think it's important that, you know, building muscle, using muscle, consistency is a huge part of effectiveness when it comes to exercise or to building strength. And so one fear we have when we say, do this in one phase of your cycle and do that in another phase, is that if, you know, 15% of patients are not ovulating, or they have no idea when their follicular and luteal phases are, are they then doing overall less because they're waiting on this directive to tell them what? What is not untrue, though, and how I frame this to patients, is that strength and resistance training should be the core of what you're doing regardless of the phase of the cycle you're in, regardless if you're pregnant, regardless if we're doing fertility treatments, building muscle, using your muscle.

• 6:40Dr Natalie Crawford?

  Now, what you do on other days is where you should allow yourself to say, how do I feel this day? What do I need this day? And be okay with giving yourself the grace that that may look different on your period, in your follicular phase, in your luteal phase, and saying, doing something and moving your body is still, ultimately, we're all gonna agree, better than sitting on a couch.

• 7:02Dr. Stacy Sims?

  Exactly.

• 7:03Dr Natalie Crawford?

  Many women will say they have more energy in that late follicular phase. And so if you are looking at your workout structure, this is a day I want to try heavier weights or more reps. It can be smart to put that in a time where you have a higher chance of being successful.

• 7:16Dr. Stacy Sims?

  That's how I explain it. I'm like, if you have your own data and you know what stays you feel really fantastic, that's where you want to put your higher intensity, your heavier lifting, because you know that you're gonna hit those training metrics. What we don't want is for someone to go in to do a high-intensity session on days they feel flat, because then they won't hit the metrics that they need to, to get the stimulus we're after.

• 7:37Steven Bartlett?

  Can you explain this to me like I'm a 10-year-old? In terms of where in the cycle typically women will have more energy and really be able to push themselves?

• 7:47Dr. Stacy Sims?

  Right here, five to seven days before ovulation. Some women feel really great around ovulation. Some have a transient where they'll feel really awful on and around ovulation. And maybe 24 hours later, they feel really fantastic. Most women are variable through the early luteal phase. So if we think about day six to 14, that's when we see women feel really robust and strong and feel like they can take on the world.

• 8:17Dr Natalie Crawford?

  Because estrogen is rising.

• 8:18Dr. Stacy Sims?

  Yeah, exactly.

• 8:19Dr Natalie Crawford?

  And you see the physiologic changes, heart rate variability, resting heart rate.

• 8:23Dr. Stacy Sims?

  Your immune system is more prone to taking on virus and bacteria. It's not pro-inflammatory, so you have that working for you. Your core temperature is lower. You can access carbohydrate a lot easier, so you have more availability for fueling to hit high intensities. Then when we see with ovulation, like I said, some women feel really fantastic right around the time of ovulation because of the estrogen surge. Some have transient where they don't feel so great.

• 8:51Dr Natalie Crawford?

  When that follicle ruptures and the egg is released, the granulosa cells that are surrounding it, which is what actually makes estrogen, get disrupted. And so some women feel that transient breakage and their estrogen's dropping before it reforms to become the corpus luteum and make again. So you have this high peak estrogen, and then some women are really sensitive to these hormonal changes, and they feel that drop. So that ovulation date may not always be your very best feeling day, which makes women feel like it should be and like something's wrong with them.

• 9:21Dr. Stacy Sims?

  On a side note, we did a survey on women experiencing pain on ovulation because it's something that was never talked about.

• 9:28Dr Natalie Crawford?

  Mittelschmerz.

• 9:29Dr. Stacy Sims?

  Yes, exactly, mittelschmerz.

• 9:30Steven Bartlett?

  Mittelschmerz.

• 9:31Dr Natalie Crawford?

  We had... So you can feel the follicle rupturing, and that's called mittelschmerz. So it's German for "in the middle" because it tends to happen in the middle of your cycle when you ovulate.

• 9:40Steven Bartlett?

  And it's painful?

• 9:41Dr Natalie Crawford?

  It's a pain.

• 9:42Dr. Stacy Sims?

  It can be.

• 9:42Dr Natalie Crawford?

  It's just a pain. It's like a cyst bursting inside your body.

• 9:45Dr. Stacy Sims?

  And then some women are down for the count because of it. So they can't, they don't plan any physical activity around that because they just can't from a physical and mental standpoint, put themselves through anything. So that's why I'm saying like ovulation, some women feel bulletproof. Other women have this transient feeling of really flatness and pain. And then afterwards in these early luteal phase, so day 16 to about day 22.

• 10:14Dr. Stacy Sims?

  It's variable. Well, some women will feel like on top of the world still. Other women will feel, mm, I can't quite hit eye intensities. And then in general, these few days, about day 24 to 27, before those hormones actually drop, this is where you have your PMS, your premenstrual syndrome and cramping and fatigue. And a lot of women are like, mm, not so great.

• 10:36Steven Bartlett?

  That's when your progesterone drops.

• 10:38Dr. Stacy Sims?

  When both of them drop.

• 10:39Dr. Mary Claire Haver?

  I just love how you guys explain it because what I see on social media is absolutes. You must do this during follicular. You must do this at ovulation. You must. And I'm just like, really? You know, and so I love how you're like, well, some women, it may affect them this way and others this. We generally tend to see X, Y, Z. So rather than like, you absolutely have to do this at these different times.

• 11:00Dr Natalie Crawford?

  I think learning to listen to your body and the signals that it's giving you, you know, across the stages of your life, that's, that's really key to so many of the questions that we're talking about because you want to understand your own response. And where many women are falling short is that they've been suppressing their cycles. They don't know about it. And they were not taught all of these different changes that are perfectly normal. And so it's very hard to then hear a social media post that says, only do this in the follicular phase and don't ever do cardio in the luteal phase. And you get a lot of mixed messages when in fact, none, there's no absolutes.

• 11:37Dr. Stacy Sims?

  No.

• 11:38Steven Bartlett?

  And in terms of training, some people think moderate training is better for women. Some people think high intensity training is better throughout the cycle and sort of also considering what goals you might have in fertility. What would you say there? Is, is, should I be doing high intensity interval training if I'm a woman? Or throughout the cycle and throughout my life?

• 11:59Dr. Stacy Sims?

  So this is where we have to think about periodization. First lifestyle, but also how a woman is feeling. We don't want people to do high intensity interval training every day because that's just not going to create an adaptive response. We have to think about, the reason why we're exercising is to create a, a stress that the body's going to respond to. We don't get fitter during exercise. We get fitter from the stimulus of exercise and the recovery from it. So if someone's doing high intensity interval training every day or five days a week, they're not ever going to get that subsequent recovery to be able to hit those high intensities and that stress that we want. We talk about high intensity during our reproductive years. You can pretty much get away with whatever you want to do during your reproductive years

• 12:42Dr. Stacy Sims?

  because you have the benefit of our hormones working for us. We start getting into perimenopause and we start getting into menopause. This is where we have to really carefully look at volume versus intensity. So that means if we're doing lots of stuff, or are we doing really purposeful, high intensity versus low intensity? Because we're trying to create what we call a polarization of the training so that when we hit high intensities, we're actually hitting the intensities we need to create change. But on the other side of it, we want to hit really low intensity so that we can have recovery. It gets harder to recover as we get older, regardless if you're male or female, but in perimenopause, we don't have the benefit of estrogen supporting anti-inflammatory

• 13:26Dr. Stacy Sims?

  responses. So we have to be very cognate that we need more recovery.

• 13:31Dr. Vonda Wright?

  So I'll give you an example. So my office, my orthopedica office, is in a fabulous performance center. Outside my windows, I have floor to ceiling windows, there's a football field inside. That field is filled seven days a week with people taking a class called IGNITE. IGNITE has a lot of midlife women in it who are never exercising at low enough intensity to recover and never exercising at peak intensity to change their body. So what happens, five or seven days a week, they're out doing moderate, mid-range intensity training, but they're not seeing body changes.

• 14:16Dr. Vonda Wright?

  They're not seeing recomposition. They're hurt every three weeks and in my office, wondering why they're hurt because they're doing a lot of reps of medium intensity. So they're not really recovering and they're not intense enough to really change their physiology. But that's really common. There are whole brands built around mid-intensity and...

• 14:39Dr. Stacy Sims?

  And that falls into the whole sociocultural thing where we've grown up that if you don't have a good sweat sesh and feel completely smashed when you leave, it wasn't a good workout. But that's a misconception.

• 14:51Dr. Vonda Wright?

  Right. So they are smashed, they're dripping with sweat, but it's not at peak heart rate ranges for short bursts of time, right? So it's, I know, look, it's very confusing because... I don't know, 20 years, people have, as they've switched from only cardio, they're like, now we're going to do high intensity, which is fine, I'm not opposed to that word. It's just that, how do you define that? What is high intensity? And so, like you, because I've read your books, that we're exercising people at pretty low heart rate, where they're about to flip from burning fat to carbohydrates, because that's really metabolically healthy, but not so intense that people are going to get hurt.

• 15:35Dr. Vonda Wright?

  And I also prescribe really peak sprint interval training, and I did that myself in midlife, you know, to recompose my body, sprint interval training, because it's intense and lifting, right?

• 15:49Steven Bartlett?

  Is the advice different for different women at different stages of life here? So if I'm before perimenopause?

• 15:54Dr. Mary Claire Haver?

  You get away with most stuff.

• 15:56Dr Natalie Crawford?

  Assuming you have a regular menstrual cycle.

• 15:59Dr. Mary Claire Haver?

  Right.

• 15:59Dr Natalie Crawford?

  I think there's different time periods, which we've mentioned before, PCOS, hypothalamic amenorrhea, time periods where you're not making estrogen or making it reliably, you can get away with less. And so we want to protect a little bit of that. But when it comes to exercise, variety is name of the game. You want to adapt, so you shouldn't be doing the same thing every day. That doesn't mean you can't have a plan, there's seven days in a week, you don't have to move every single one, but you should pick these different activities based on your life, your schedule, what you want to accomplish, and it will vary some in different phases of your life, because your goals are going to be different. And so when it comes to exercise, we always have to think about what needs to happen. Are you somebody who is overweight and needs to lose weight?

• 16:43Dr Natalie Crawford?

  Are you somebody who's underweight and is trying to gain weight? Are you trying to get pregnant or going through fertility treatments or in menopause? So there's nuance to it, which always makes it hard, but there's not a one, do this one exercise every single day, that's pretty much not the answer.

• 16:58Dr. Mary Claire Haver?

  So the most popular class for females right now, I just saw the statistics somewhere, is Pilates. And my daughter loves her Legria and gets on that machine, it's like, you know.

• 17:09Dr. Stacy Sims?

  Where does that fall in all of this? I have a lot of Pilates. There's a social aspect to it, you know, there's.

• 17:17Steven Bartlett?

  People hate.

• 17:18Dr. Stacy Sims?

  Yeah, because we did this reel talking about how Pilates was not appropriate as strength training, especially as a rehab. When we look at Pilates, it's a complement to true strength training. What I mean by true strength training is you're lifting a load that's heavy in multiple planes. With Pilates, it's really good for isometric control, core strength, balance, proprioception, but it isn't a stress that's going to create adequate muscle gain and strength of the bone, which is what we want from strength training. So just like yoga, Pilates has a place. It does definitely fit in the scheme of things, especially from the social and the fact that does give you control and proprioception, but it isn't the be all, end all for strength.

• 18:03Steven Bartlett?

  People that do Pilates frequently will be shouting, Stacy, it's so, it hurts so much and.

• 18:11Dr. Stacy Sims?

  I know.

• 18:11Dr. Vonda Wright?

  Well, I'm sure it's hard. The times I've done it, it's not easy, but the room. But it doesn't set you up not to be frail. It is not building strength and power. And I have women who have done so many Pilates, 1,500, it's like a badge of, they count their classes. 1,500, at the deficit of anything else. It's all that goes on. And, and I think that is another, you know, you've got to mix it up, number one. Number two, I say the same thing, so I'm not very popular in those crowds, but it's great for the, for the standard that I ask people do of flexibility and joint range

• 18:53Dr. Vonda Wright?

  of motion so that you don't become really stiff and hunched over and shuffling old person, but it will never give you strength and power in the way to protect yourself from falling down.

• 19:05Steven Bartlett?

  Because there's not enough weight?

• 19:07Dr. Stacy Sims?

  For the most part, yes. And we also have to think about when you're doing strength training, you are in, you're creating a multidirectional force through the muscle and the tendons and the bones. With Pilates, especially if you're looking at the reformer, it's not multidirectional in the movements. Each movement is one plane and you can be.

• 19:25Steven Bartlett?

  Up, down.

• 19:26Dr. Stacy Sims?

  Yeah, you can be in, in different planes, but each motion isn't multi-planar. So if we think about what are we trying to get out of Pilates? We're getting neuromuscular control. We're getting core strength. We're getting some breath work and all that is beneficial. But again, if we're trying to grow muscle and bone, take up space, be strong, it doesn't quite hit the points that we need to in order to create this new strength to bring us to that health span that women are looking for. So do it a couple of times a week? Yeah. Not seven days a week? Correct.

• 20:00Steven Bartlett?

  So if my partner, she's 33 years old, so she's not quite at perimenopause yet. If you were to design a perfect workout regime for her at that phase of her life, what would you? Oh, Stacey's clapping. You know, go ahead.

• 20:16Dr. Stacy Sims?

  So if she has three days that she can go to the gym and has, well, I should say, three one-hour sessions that she could have at the gym in a week over seven days. Each one would start with mobilization. So using resistance bands or maybe you're doing a Pilates reformer warm-up. So you're getting through the range of motion.

• 20:36Steven Bartlett?

  Why?

• 20:37Dr. Stacy Sims?

  Just to open up the joint capsules, make sure you don't have any restriction so that you can get really good range of motion for the movements you're going to do next. The next movements would be...

• 20:47Steven Bartlett?

  Does that stuff actually work? I do wonder this. So many of my friends are getting injured at this age because they're my age and a bit older because they walk into the gym and they start picking weights up.

• 20:54Dr. Stacy Sims?

  Oh, yeah. No, I mean, I spend more time mobilizing, I think, than I do actually training now just to keep range of motion going and keep the joint capsules open. And so that's using the heavy resistance bands to distend and distract all the joint capsules to increase range of motion. Stretching doesn't do that. Stretching will get to an end point of the muscle to allow you to have more flex in the muscle, but it's not actually stretching in the joint capsule to give you range of motion. So when we talk about mobility work, we want to get into that full range of motion. So if you have a stiffening, so as I was saying earlier about the guy and my voodoo flossing, well, voodoo floss is a way where you're creating some blood flow restriction. Then you go in a range of motion and a blood flow restriction.

• 21:37Dr. Stacy Sims?

  You take the voodoo band off and the blood flow comes back and you go in the range of motion, get deeper in that range of motion. So it's all about accessing the tissues and making the tissues more viable for increased range of motion so that when you go do the lifting, when you go put on a heavier load, you have better control, better range of motion and avoid the small little sticky points that cause injury. Micro tears? Yeah.

• 22:00Steven Bartlett?

  Uh, so it's the micro tears that are going to lead to inju- inju- injury. And the micro tears come when I haven't warmed up.

• 22:09Dr. Stacy Sims?

  Warmed up properly, yeah. So like for your shoulder, what would that look like? For your shoulder? Uh, I wish I had a rig. So you could take one of those thick, um, big bands, the big, and wrap it around a rig or, or something and you can pull and distend. So you're actually pulling the shoulder out in different ranges. So you can rotate, roll, pull, extend, pull, extend. So this is more trying to work the muscle, right? And you have paleo press as well where you're working rotation, but that's not getting into the joint.

• 22:41Steven Bartlett?

  So you might be.

• 22:42Dr. Stacy Sims?

  So if you're distending, you're pulling back. You're not bending your elbow. You're actually pulling through the shoulder and distracting. And then the band is going to pull you forward to give you resistance to pull your shoulder joint out. And it's not a painful, but you're just really getting into that full joint capsule. You can do that with the hips. You can do a banded pigeon stretch. Just so many different ways of getting into the joint capsule, which not only gives you more range of motion and prevents injury, but it also gives you more of the flexibility that people think they get when they're stretching.

• 23:15Dr. Vonda Wright?

  The reason this is important as we age is because ligaments and tendons and, uh, the capsule, the inside skin of a joint is made of collagen. And the covalent bonding, collagen is like if you envision strands of rope. The covalent bonding, meaning the bonding between those strands becomes stronger as you age and you, uh, become more and more stiff. Well, when we lose joint range of motion, we're injured more. Um, it's why we start shuffling down the street, hunched over, shuffling instead of striding, because we have full hip range of motion or full knee range of motion.

• 23:55Dr. Vonda Wright?

  And so one reason to do this is to maintain full range of motion through all of our joints. We want full range of motion, not only to avoid injury, but for instance, if your knee is stiff, whether it's an. Injury or because you just haven't maintained your motion. It will change something called your kinetic chain, meaning we really are from our big toe to through our spine. Connected the big toes, connected to the foot bone, the foot bone, because the way each of those body segments works. Activates the next body segment. So if you've got a glitch in the system because your knee doesn't move. Or let's take this one. This is easier. Your ankles get stiff because we've never worked on it. Your calves are tight.

• 24:40Dr. Vonda Wright?

  Right? You're a jumper. You've got tight calves. Your, your hip, your ankle doesn't flex. Well, then. Your shin bone or your tibia is not going to internally rotate. Well, without that. Your knee is not going to bend as much and your femur, your thigh bone is not going to rotate. You must have the rotation of these bones to activate your glute. So if you're not activating your glute, your butt muscle. People are very hurt or they're not getting as strong or they start having lateral thigh pain. So everything works together. And it starts with, among other things. The flexibility and range of motion exercises. We're talking about it right now. So that the body works like a chain.

• 25:26Steven Bartlett?

  Just give me 30 seconds of your time. Two things I wanted to say. The first thing is a huge thank you for listening and tuning into the show. Week after week means the world to all of us. And this really is a dream that we absolutely never had and couldn't have imagined getting to this place. But secondly, it's a dream where we feel like we're only just getting started. And if you enjoy what we do here, please join the 24% of people that listen to this podcast regularly and follow us on this app. Here's a promise I'm going to make to you. I'm going to do everything in my power to make this show as good as I can now and into the future. We're going to deliver the guests that you want me to speak to and we're going to continue to keep doing all of the things you love about the show. Thank you.

• 26:07Steven Bartlett?

  If I lose my range of motion because I never did all these things, can I get it back when I'm 50? So like, you know, I'm 33 now, I'm like, damn, I've not been doing enough of this stuff.

• 26:15Dr. Stacy Sims?

  Yeah, yeah, you can.

• 26:17Dr. Vonda Wright?

  Unless you're having bone changes due to arthritis and it's blocked, yes, you can.

• 26:21Steven Bartlett?

  So I can start it, I could theoretically start at 40.

• 26:24Dr. Stacy Sims?

  Because if you think about your muscle and how it responds to picking up a weight and you're right, you're going to build the muscle. So if you're creating a force within the tendon and the ligament and the collagen, and it's a repetitive force, a positive force, you're going to invoke change. So people that's tissues are malleable.

• 26:40Steven Bartlett?

  So people that think they're stiff and they say, you know, I can't touch my toes and

• 26:45Dr. Stacy Sims?

  They can work on

• 26:45Dr. Vonda Wright?

  They can get it back. Here's another reason. So what happens in midlife, men and women, actually, they remember what they used to do. And then they're like, I'm gonna start working out and I'm gonna

• 26:57Dr. Stacy Sims?

  Start there.

• 26:58Dr. Vonda Wright?

  Their success. This is when I get people who just show up on the basketball court after not having been there for quite some time. And they return to their memories of success, but because they haven't lengthened their tendons, their joints aren't moving quite so well, they rupture tendons because the load outstrips the ability of the tissue to be compliant.

• 27:22Steven Bartlett?

  Hmm, that makes sense.

• 27:23Dr. Vonda Wright?

  Yeah.

• 27:24Steven Bartlett?

  My friends have been getting injured and I think that's in part why because they're trying to work out like they used to work out.

• 27:28Dr. Vonda Wright?

  Yeah. And listen, they can return to really high level, but you can't stop. You can't start where you left off 20 years ago or 10 years ago. It takes a minute.

• 27:40Dr. Stacy Sims?

  Weeks for me.

• 27:41Dr. Vonda Wright?

  It takes a minute. Yeah.

• 27:43Steven Bartlett?

  So Mel's 33, you

• 27:44Dr. Vonda Wright?

  Yeah.

• 27:45Steven Bartlett?

  Mobility work when she gets to the gym.

• 27:47Dr. Vonda Wright?

  Yeah.

• 27:47Steven Bartlett?

  First and foremost.

• 27:48Dr. Vonda Wright?

  Yep.

• 27:48Steven Bartlett?

  On day one or every day?

• 27:50Dr. Stacy Sims?

  Every day.

• 27:51Dr. Vonda Wright?

  Every day.

• 27:51Dr. Stacy Sims?

  So I'm assuming, and I could be wrong, that she already has a strength training history.

• 27:56Steven Bartlett?

  Yeah, she does, yeah.

• 27:57Dr. Stacy Sims?

  Okay, so we do the mobility work for about 10 minutes, really warm up well. Then we pick one compound movement we're going to work on. So it could be squats on the Monday. So we're going to work on loading in a squat pattern. So that's your knee forward, you know, quad dominant type squat. Back squat, does it matter? Back squat, front squat. You could do Bulgarian split squats. So we're adding load and we have a periodized program. So this is just a snippet of one day in a periodized program.

• 28:27Steven Bartlett?

  What if she didn't have that strength training history?

• 28:29Dr. Stacy Sims?

  Well, then we work on adding load through our, I want to see how she moves first. And we want to make sure that you're moving well before you add load. So this is where we work with lighter loads and more reps.

• 28:42Steven Bartlett?

  What if she's, doesn't have you there?

• 28:45Dr. Stacy Sims?

  Yeah, that was my question. Like, what if you're not there? Yeah. What if she do on her own? Yeah. So this is still like, how do you squat? Where are your sticking points? So you can assess, self-assess. If you've done your mobility, then you'll know like, oh, my hip's really tight. So I need to work on that. So let me do some air squats to see how I move. Then the next time you go in to do squats, maybe you're picking up two 10 pound dumbbells and you're holding them and doing air squats with your dumbbells. And eventually you're going to move to the barbell. So it's all about small progression under load to get to a point where you feel more confident to use a barbell back squat to get into more of those compound movements.

• 29:24Steven Bartlett?

  Why don't people exercise? Specifically, if we just focus here on women, what is the reason why people hear what you guys say when you're talking about exercise? And they don't do it? They don't start?

• 29:36Dr. Stacy Sims?

  It's hard.

• 29:37Steven Bartlett?

  For what, what set of reasons make it hard?

• 29:39Dr. Stacy Sims?

  Well, for women, it's set up in a gendered environment. Like I always use the example of a woman who is an interest in strength training. If they go to a typical like 24 hour fitness or another brand gym that's out there, they'll walk in and they'll say, yep, I want to join. And the membership person most often will say, great, here's the class schedule. This is where we have our spin classes. This is where we do our bootcamp classes. They never direct them to the lifting platforms. They never look and say, hey, here are, are the way to get strong. Because they are under the assumption through sociocultural ideas that a woman is coming

• 30:21Dr. Stacy Sims?

  to the gym to lose weight, not to get strong, not to gain muscle. Not to recomposition. Right. But if a man walks in.

• 30:29Dr. Vonda Wright?

  Then it's always the great, here's the lifting platforms. We have X amount of barbells. We have X amount of bumper plates. How much weight do you want to gain? Do you, do you want to work with someone to, you know, help you build that mass?

• 30:42Steven Bartlett?

  Fonda, why does it matter? You know, because there's a big social pressure on women to look a certain way. And it doesn't typically involve muscles in the, especially in the upper body.

• 30:53Dr. Vonda Wright?

  No. So, you know, we're still living under the times of be as small as you can. But small doesn't mean lean. There's a concept of skinny fat, which, you know, it's, you can be as tiny as tiny, but you can be 50, you can have a body fat of 50%, which means you're neither strong. You're not metabolically healthy. You're just little, right? So it's, there is also a misconception that lifting heavy is going to automatically turn you into a physique model or a bodybuilder shape. If that's your goal, that's probably going to take you five years or a decade. It's a lot of hard work for a long period of time with proper nutrition.

• 31:37Dr. Vonda Wright?

  So for a woman who's, wants to feel better, the goal is to build muscle to be lean, to recompose, not lose weight, right? I'm not really interested in somebody's weight. I'm interested in their body fat percentage and their lean muscle mass. Because it's what you're made of that matters, right? Not the size of the shell.

• 32:04Steven Bartlett?

  And why does muscle matter as I age, as a woman in particular?

• 32:07Dr. Vonda Wright?

  It matters for everyone, but for muscle matters because it's not just part of locomotion. It's not just part of moving you around. It is a metabolic organ. It is critical for glucose metabolism. It's critical for insulin sensitivity. It talks to the bone, bone and, bone and muscle are endocrine organs, which cross communicate all the time. So both bone and muscle have access to the brain, right? Muscle will produce a hormone called irisin, which has multiple functions in the body. The the axis between muscle and brain helps your brain produce more neurons,

• 32:51Dr. Vonda Wright?

  right? Bones access to the brain has a role in satiety. Isn't that amazing? Which means not hungry anymore. Why would you think these locomotive structures, if that's what you limit them to, would would even have those functions? It's because we put organs in a box. So to answer your question, muscle in men and women, but women in particular for this conversation, we need as much muscle as possible to fight the insulin resistance that we get when estrogen walks out the door. We need muscle for glucose metabolism. We need muscle for the pure strength of it

• 33:35Dr. Vonda Wright?

  because we do not want to become frail and be one of the two thirds of nursing home residents who are women because we can't do something as simple as get up out of a chair.

• 33:47Steven Bartlett?

  But I could just get muscle when I'm 70.

• 33:49Dr. Vonda Wright?

  You can, actually. It's a lot harder.

• 33:51Steven Bartlett?

  So why does it matter for Mel to be thinking about it when she's 33?

• 33:54Dr. Vonda Wright?

  Well, here's the great part for Mel is she still has all her estrogen. Estrogen has a profound effect on muscle protein synthesis. It is a significant anti-inflammatory. So high inflammation, chronic inflammation, if we've talked about, decreases muscle synthesis. It decreases bone synthesis because inflammation with its high cytokine level, I've mentioned them before, IL-6, tumor necrosis factor, those are all detrimental to these normal metabolic pathways. So the wonderful thing for Mel, who is entering what I call the critical decade, which is 35 to 45 estimated,

• 34:38Dr. Vonda Wright?

  it's the prime time to set your physical activity standards and to build as much as you can while you've still got all your estrogen.

• 34:47Dr Natalie Crawford?

  In addition to the fact that for proper hormonal health, if you think about inflammation coming in, it's like static on a walkie talkie. The brain's trying to interpret your hormones. And when inflammation's coming in, it's making the signals really hard to hear. So we need to make sure that we're actively fighting that. And building muscle is one great way, because it's going to use up glucose and fight insulin resistance, which means makes your cells more sensitive to when it sees glucose and able to use it better. If you have another thing that is pro-inflammatory, such as PCOS or endometriosis, it's even more important for you, because your inflammatory burden, by default of what's happening at a cellular level, is higher. We now need to not just say, I need to not make it worse

• 35:32Dr Natalie Crawford?

  by being exposed to things. We have to say, I need a plan to fight this, because my world is pro-inflammatory on a daily basis. What is my game plan to fight this? And building muscle. It's not just, exercise is better than no exercise, but specifically building muscle, because as everybody's saying, it has a metabolic function in your body, is going to help you the most.

• 35:54Dr. Mary Claire Haver?

  There's a term called geroprotective, geroprotection. So gero is the term we use for aging. So gerontology is the, you know, the part of medicine that focuses on the elderly patients. And so when we look in females, and the organs that are, you know, are the most geroprotective, it is the muscle and the ovary. And the ovaries go away. We have a shelf life in our ovaries. So then we're just really left with our muscle, as far as protecting us in those elderly years as we age. And it's directly correlative to the amount of muscle that we have. Because if you have a lot of muscle, you're gonna have stronger bones.

• 36:29Dr Natalie Crawford?

  And this is where the intensity part, where Dr. Rice is talking about seeing the Ignite class, and everyone's in that moderate intensity all the time. With moderate intensity, you don't have the post-exercise anti-inflammatory response. So if we're trying to build muscle, or we're trying to dampen inflammation, if we're always doing this moderate intensity cardio, then we're not, one, going to be building the muscle we want, and two, we're going to have this baseline elevation.

• 36:57Dr. Vonda Wright?

  Of total body inflammation. So we need to mix it up and have that precedence on being muscle centric and building that muscle. One to help with aesthetics. I mean, that's the byproduct of lifting weights. You tend to look better, but it's more than that. We see it improves brain health because of the neuroconnections and the neuroplasticity of the brain. And I tell

• 37:19Dr. Stacy Sims?

  Sleep, mood.

• 37:20Dr. Vonda Wright?

  All of those things. Yep. You get an incredible parasympathetic response when you've done a significant heavy lifting session or a sprint interval session, which you don't get with that moderate intensity cardiovascular work.

• 37:32Steven Bartlett?

  Two questions to add to what you you'd better say here is, um, am I right in thinking that at the end of that golden decade that you referenced, forty five years old?

• 37:41Dr. Vonda Wright?

  Hmm.

• 37:42Steven Bartlett?

  Because you have changes in estrogen, one will expect to see a natural decline in muscle.

• 37:48Dr. Vonda Wright?

  Yes.

• 37:48Steven Bartlett?

  Um, and an increased chance of osteoporosis, osteopenia, bone issues later in life. Do women, this is several questions, I apologize, but do women then also tend to have more frail bones in later life? And is that linked to the muscle loss?

• 38:02Dr. Vonda Wright?

  So this is how it works. So both men and women build bone and peak about up to twenty five, sometimes thirty. And then bone loss plateaus for a little while. Men continue to lose about one percent a year. So men do not arrive with hip fractures or devastating fractures until their seventies or eighties or older. Women also decline slowly until we lose our estrogen. And then the rate of decline, and I'll tell you why it happens for bone, doubles or triples such that you will lose fifteen to twenty percent of your bone density during your perimenopausal period, just from loss of estrogen alone, because

• 38:45Dr. Vonda Wright?

  estrogen plays many roles. I've already talked about estrogen being a huge anti-inflammatory. Bones are very sensitive to inflammatory chemicals in your body.

• 38:57Dr. Vonda Wright?

  Estrogen also directly affects the balance of the two main cells that subtract minerals from bone, the osteoclast, and the cell that builds the bone, the osteoblast. And in well-hormoned times, there is a balance. The body loves balance. We take what we need, we build it back. But because estrogen has such a profound effect on the osteoclast, the Pac-Man bone-eating cell, there's an imbalance and we take more bone than we're capable of building. We're still building bone, but the rate cannot keep up with this.

• 39:36Dr. Vonda Wright?

  So with the inflammation, with the direct effects on the osteoclast, women will lose bone density if they do nothing. Well, number one, they're going to lose bone density, but they must do something about it. The reason it's so critical for a 33-year-old is because you still have your estrogen. So let's learn how to lift heavy. Let's take advantage of the estrogen circulating. Let's learn to have a jumping practice and impact our bones, right? So the way our body tells our bones to build more is, there's another little cell called the osteocyte.

• 40:16Dr. Vonda Wright?

  It sits encased in bone, but it's connected to these other cells by little tunnels that contain fluid. When you jump, the biomechanical impulse of that fluid shifting in the little tunnels is translated into a biochemical stimulation that tells the bone, "Oh, my God, she's jumping around. I need to build more bone." So we need that impact to stimulate the laying down of more bone.

• 40:44Steven Bartlett?

  I was looking at this graph, which is what you were describing.

• 40:47Dr. Vonda Wright?

  Yeah.

• 40:48Steven Bartlett?

  Men and women aren't that far away in terms of...

• 40:54Steven Bartlett?

  Bone mass?

• 40:55Dr. Vonda Wright?

  So this is showing the fact that because of the way testosterone interacts with a man's bones, he will peak at a higher bone mass than a woman will.

• 41:04Steven Bartlett?

  Yeah.

• 41:04Dr. Vonda Wright?

  So he's starting at a higher level.

• 41:06Steven Bartlett?

  Yeah.

• 41:07Dr. Vonda Wright?

  So I would want young women to do everything humanly possible to start at the highest possible level. But I see lots of 20-year-olds, 30-year-olds, really young women with poor bone density for a lot of reasons. And so I'm a big proponent for having bones measured early. Don't wait until you're old so you know where you're starting. But that's not the standard recommendation. No, the standard recommendation is 65, which Cows out the barn. It's way too long for that. But because I do do either a DEXA scan or a REMS ultrasound to look at bone quality on everybody, we can catch it earlier.

• 41:49Dr. Vonda Wright?

  And that's really important to get in front of it because it's estimated, research says that in order to affect bone density, if you're going to use estrogen, for instance, you need to have do it for 10 years.

• 42:01Steven Bartlett?

  And why should people care about bone density? Everyone cares about muscles, but very few people talk about bones.

• 42:05Dr. Vonda Wright?

  Fracture. Can't carry your muscle around if you have weak bones. So without bone, muscle is just a heaping pile of steaming metabolic tissue sitting there, right? There would be no bicep to compliment, right? Because it has to be connected to a bone. So they're important for locomotion and giving support to the muscle. But bone is an endocrine organ that secretes hormones that go to your brain to help build neurons, to your pancreas, to be active in insulin release, to the muscle for glucose metabolism. In men, to the testes to build testosterone. And that's only one of the many hormones that the bone produces.

• 42:47Dr. Vonda Wright?

  The bone is not only structural, not only hormonal, I've already talked about it being a storehouse, but it's an incubator. And our pelvis is where we build all of our blood cells. And so it has these multi-functions.

• 43:04Dr. Vonda Wright?

  But to Mary Claire's point, for women, forty to fifty percent of women will have low bone density. And when you have that, fifty percent of the time, you'll break a bone. So if we're looking around at this table, if we all have osteoporosis, which we don't, one in two of us will fracture. When that fracture is a hip fracture, which is very common, seventy percent of all hip fractures happen in women, thirty percent of the time, when you hit the floor and something breaks, you have a chance of dying in one year. This quick, your life changes. Fifty percent of the time, even if you survive, you will never return to pre-fall function, meaning you can't go home. And that puts

• 43:48Dr. Vonda Wright?

  your family in this situation of having to figure out twenty-four hour care, or you move in with your eldest daughter, or you go into a facility where you use your life savings until you have no more, and then you have to apply for Medicaid, and the government will pay for it. These are terrible situations to get at something that we could have prevented had we started early enough.

• 44:17Steven Bartlett?

  So you want to start early. So I have Mel. So Mel's going to be doing strength training, not just for the muscle benefits, but also because it's going to help her build strong, healthy bones in that critical decade.

• 44:27Dr. Stacy Sims?

  Yep. And then we finish it with some jump training.

• 44:30Steven Bartlett?

  Jump training.

• 44:31Dr. Stacy Sims?

  Yeah. So plyometric type work, or if we're looking at not having the robustness of doing straight plyos, then you can do band assisted pogo's, you can do low depth jumps, you're getting some impact at the bone, because as Dr. I was talking about, it's a multidirectional stress. People think, oh, I run, I'm going to have strong bones. But running doesn't do it. You need multidirectional stress. So if you think about it, when you land, your body has to move, the ground doesn't. So it's called the ground reaction force that comes up through the bone to create that strength. So that ideal situation in a workout for her would be some mobility, some heavy lifting. If we're doing plyo, that's

• 45:12Dr. Stacy Sims?

  also strength or sprint type training, so you're getting a metabolic stress. So you're hitting all the major factors in one one-hour workout.

• 45:20Steven Bartlett?

  I read that there was a study done with some Australian. Elderly ladies on bone growth.

• 45:28Dr. Vonda Wright?

  On lifting and bone growth?

• 45:30Steven Bartlett?

  Yes.

• 45:30Dr. Stacy Sims?

  Yeah, lift more.

• 45:31Dr. Vonda Wright?

  And the Lift More study by Dr. Beck.

• 45:33Dr. Stacy Sims?

  Yes.

• 45:34Dr. Vonda Wright?

  She was trying to dispel the myth, which I hear every day, that you've got osteoporosis, you can't lift weights.

• 45:39Dr. Stacy Sims?

  Yes.

• 45:40Dr. Vonda Wright?

  And so her study, because we're big proponents of teaching people to progressively lift heavier and heavier, and that scares people, but especially if you think you're gonna break. So she did a study where the load was five reps, five sets, under a supervised situation. So five reps means that it was heavy enough that at five reps, they were near failure, right? So these women, all osteoporotic, not only were capable of lifting heavy under supervision, none of them broke, and they built bone.

• 46:16Dr. Stacy Sims?

  Yep.

• 46:18Dr. Vonda Wright?

  So that answers the question.

• 46:20Dr. Stacy Sims?

  Right.

• 46:21Dr. Vonda Wright?

  Can you lift? Yes.

• 46:22Dr. Stacy Sims?

  Yes, you can. And the other thing that isn't really brought up into these conversations is when you hit perimenopause. Not only is estrogen sort of the stimulus for satellite cell, we're building muscle cell, but it has a distinct, I guess, influence on myosin. So myosin and actin are two contractile proteins. So if you think about a sliding filament or coming together, you have myosin and actin that bond together to then pull and move and pull and move, and that's how you have a muscle contraction. Estrogen is responsible for how tightly myosin bonds to actin. When we start to lose estrogen, or we start to

• 47:03Dr. Stacy Sims?

  have variability in our estrogen, we get myosin dysfunction. So that means we're not gonna get a very strong contraction.

• 47:10Steven Bartlett?

  So we get weaker?

• 47:11Dr. Stacy Sims?

  We get weaker. And this is one of the very first things that people complain about to me. I don't have power. I don't have strength. I can't, my grip strength's gone. I don't know, but their body composition hasn't changed yet. So if we think about lifting heavier loads, it's a neuromuscular response. And that direct stimulus creates the adaptive change in myosin that now estrogen isn't responsible for. It's a different external stress that creates that change in myosin to go, yep, I have to grab on to actin and have a very strong contraction. So we see that this dysfunction happens first before we start seeing a change in our lean mass development. So if we are already in the habit of lifting heavier loads, then we can offshoot some of

• 47:55Dr. Stacy Sims?

  that myosin dysfunction that occurs with the estrogen change.

• 47:58Dr. Mary Claire Haver?

  So when my patients come in and they are looking to prevent osteoporosis, or they've gotten a diagnosis of low bone density, you know, what can they do? I've discussed the Liftmore trial. The new study just came out, May of this year, 2025, and they looked at, very similar to the protocol used in Liftmore. So there was a control group where they just did nothing. Then a group that did, they did three days a week and they did resistance training and jump training. And then the third group did all the same exercises and added HRT. And depending if they had a uterus, they got estrogen or estrogen plus regestagen. And so, of course, as expected, the do nothing group lost bone. You gained bone, as expected, in the resistance group, but it seemed to be synergistic.

• 48:41Dr. Mary Claire Haver?

  When we added hormone therapy and the resistance training together, they grew even more bone. They had even better results. So when my patients are like, I want to hedge my bets. My mother fell and fractured. She's broken her hip in a nursing home, whatever, and I'm trying to avoid this. I'm, we're hitting all the points. And the only medication of it, now, we have other medicines that will help slow down resorption of bone, the bisphosphonates and stuff, but they, you know, they can be hard to take and they have a lot of side effects. So to me, prevention is always better than cure.

• 49:12Dr. Stacy Sims?

  Yeah.

• 49:12Dr. Mary Claire Haver?

  Right? So I'm trying to get them and get them early. I just ignore the guidelines that say you have to wait till 65 unless you have some chronic medical condition to get a bone density. I'm telling patients, you can find it for about $99 around, I work in Houston, and that is worth the investment for you to go get your baseline bone density. I don't know a single orthopedic surgeon, you know, a sinker, exercise physiologist, or anybody who deals with osteoporosis who thinks 65 is a good idea. So if your listeners are like, oh, well, you know, my insurance won't pay for it, I'm like, There are centers popping up now where you can go and get a DEXA scan and just pay out of pocket and get a great, you know, and figure out where your starting base is.

• 49:52Steven Bartlett?

  A DEXA scan is?

• 49:54Dr Natalie Crawford?

  A bone scan to see your bone density is the easiest way to describe it.

• 49:57Steven Bartlett?

  And your muscle mass.

• 49:58Dr. Mary Claire Haver?

  Yeah, they can do that as well.

• 50:00Dr Natalie Crawford?

  This conversation is really important, though, to extend besides just menopause or perimenopause, that there are women of reproductive age years who have profound periods of low estrogen, who are also at risk for serious problems with their bone density, both now and down the road. And so if you come to me and you say, "Oh, I haven't had a period for seven years. No big deal." Well, that is a big deal. And depending on the reason why, many of the causes will result that you had low estrogen and you were not ovulating and you have hit that graph you showed of while you're building your bone, that person's on a different trajectory. And those women do need bone scans much earlier so that we can see where they are and see what treatment we need.

• 50:44Dr Natalie Crawford?

  But it's one of the biggest reasons, bone health is one of the most acceptable medical reasons for why we should put younger women who have low estrogen time periods onto estrogen treatment because it can so profoundly change their bone health long term.

• 51:00Dr. Stacy Sims?

  So in my niche of active women, we see there's a very, very high incidence of recreational active women in low energy availability, meaning they're not eating enough to support daily life as well as their training. So the subclinical aspect of not eating enough creates a myriad of issues that does create lower bone density, menstrual cycle dysfunction, greater inflammatory responses. So, you know, the end result would be hypothalamic amenorrhea, so their periods have stopped, which is that low estrogen standpoint. So, you know, keeping track of your period, make sure you're eating enough,

• 51:43Dr. Stacy Sims?

  is one of the first stopgaps that we have in the athletic realm. It's like, we want you to eat enough, and if you're looking at bookending our calories on either end of the day, that's not appropriate. We have to look at how your circadian rhythm works because the circadian rhythm, like we talked about in the first half, was about the pulses of our hormones. So if we're holding our calories on either end of the day, then there's this big space in the middle of the day where your body thinks it's under a starvation threat. So you start to have this downturn of all of our metabolic functions. We see after four days of low energy availability, there's a direct impact on thyroid function. So we have to be very cognate that women who are saying, I haven't had a period in

• 52:24Dr. Stacy Sims?

  seven years, or my periods are really irregular, we have to bring it back to the energy function as well. So I know unfortunately, we're still in this environment of aesthetics and I'm always like, we need to eat. And if you eat in and around your training and fueling appropriately for what you're doing, it has a positive impact on body composition. You're not going to gain body fat, you're going to gain lean mass, you're going to gain bone, and you're going to see a decrease in body fat. But it's a trusting the process that out in general socio-cultural concepts is just not acceptable for so many women right now.

• 53:01Steven Bartlett?

  And with that exercise regime I asked you to make for a woman that's pre-menopause, was there anything left off there? We had day one, which is mobility works, strength, training.

• 53:11Dr. Stacy Sims?

  So if you were to do three days a week in the gym, that would be pretty similar except for the compound movement. What are we doing for each of those compound movements?

• 53:20Steven Bartlett?

  A different muscle.

• 53:21Dr. Stacy Sims?

  So it would be the knee forward squat motion one day, push pull, upper body next, and then posterior. So your hip thrusts, your deadlifts, that kind of stuff, because women are quad dominant. To prevent injury, we really need to build the posterior chain. And this is your glutes, your hamstrings. Your deadlifts. Yeah, so you're getting really strong around the knee joints, the hip joints, because again, that feeds forward to better movement, movement economy, and prevention of misstep for a hip fracture later down.

• 53:53Steven Bartlett?

  What about cardio?

• 53:55Dr. Stacy Sims?

  So that's where, like, if we're looking at those three days a week and we're finishing with plyos or some sprint work, then the other days, just walking, low level intensity walking, or maybe you have soul food, you wanna go for a bike ride, you wanna go for a run, if you're not training specifically for something, then those three strength training days are your key workouts, and then you can pepper in all the other things that you like to do.

• 54:17Steven Bartlett?

  I hear a lot about VO2 maxes, so I thought, thought we should all be driving our cardiovascular performance up to get a high VO2 max.

• 54:24Dr. Stacy Sims?

  Well, that's where the intensity is, yeah.

• 54:26Dr. Mary Claire Haver?

  I think it's, I mean, and correct me if I'm wrong, but my understanding after reading and watching everything is, doesn't take that much to build VO2 max.

• 54:33Dr. Stacy Sims?

  No, doesn't. It's that high intensity that's a little bit uncomfortable, where you're pushing at that max for, uh, you know, about four minutes to build that VO2. In the sports science world, it's always been the four by four, the Norwegian four by four. Four minutes on, four minutes off, four minutes on, four minutes off.

• 54:52Dr. Vonda Wright?

  But that's not three days a week.

• 54:53Dr. Stacy Sims?

  No, not at all.

• 54:54Dr. Vonda Wright?

  Norwegian protocol is once a week.

• 54:55Dr. Stacy Sims?

  Once a week at the most, right.

• 54:57Dr. Vonda Wright?

  And the other sprints, just to give you, I tend to give my examples, because it makes it more real, but when I'm doing sprint intervals, um, I do it the thirty seconds on, and then complete recovery, meaning I'm, for thirty seconds, I'm taking my heart rate as high as I can get it, and then I'll completely recover, which takes me two to three minutes. I just happen to do it on a treadmill, but the reality is, you can do it on anything. It's a heart rate function, not an apparatus function. So, for me, on a treadmill, after I'm done warming up, you can't do it cold, or you'll hurt something.

• 55:38Dr. Stacy Sims?

  Exactly.

• 55:38Dr. Vonda Wright?

  After I'm done warming up, because I'm a really short person, I punch the treadmill up to eleven, and I am just working so hard, I don't fly off the back. But that gets my heart rate up really high, about one eighty-six. Everybody's top heart rate is different. And then, I completely recover, and I do that four times.

• 55:59Dr. Stacy Sims?

  And that's all you need.

• 56:00Dr. Vonda Wright?

  It doesn't take that long, and you feel so good when you're done.

• 56:04Dr. Stacy Sims?

  Yeah. So I can't run at the moment. This morning, I did explosive kettlebell swings.

• 56:08Steven Bartlett?

  Why can't you run at the moment?

• 56:09Dr. Stacy Sims?

  Uh, I've torn hamstring and meniscus, so I can't run at the moment.

• 56:13Steven Bartlett?

  Running is in.

• 56:14Dr. Vonda Wright?

  Hmm.

• 56:15Steven Bartlett?

  Run clubs have come in strong.

• 56:18Dr. Stacy Sims?

  It's back.

• 56:18Steven Bartlett?

  It's back in.

• 56:21Steven Bartlett?

  Are you at all concerned with the fact that people are running all the time and doing resistance training less? Because running is cool like cool now, it's how people date.

• 56:31Dr Natalie Crawford?

  Yeah.

• 56:32Steven Bartlett?

  It's they're not going to nightclubs.

• 56:33Dr Natalie Crawford?

  It's a sacrifice of other things. It's like we said about Pilates, you know, if all you do is running, then that is definitely not the best way to be. It's not the healthiest for your whole body. It's not that you're unhealthy, but we're really talking about how are we optimizing your body, your hormonal health for a variety of different goals. But also, if we look very micro at running, fifty eight percent of runners have a luteal phase defect. That means that the second half of their menstrual cycle is not going to be able to last as long as we want it to, likely due to what Stacy was talking about earlier, this relative energy deficiency coming back to the brain, the brain signals is not as strong to keep that corpus luteum,

• 57:14Dr Natalie Crawford?

  what happens after the follicle, alive. And a lot of women, I still have my period, so I'm okay. But if we're using our cycle as a vital sign, we can actually say the ratio of energy balance is not great. And it's often because we're doing it at sacrifice of other things. So if you're doing the strength training three times a week, and you're running, however you're spacing out your other days, that's such a healthy balance, it's hard that you're going to be in a bad position with that.

• 57:41Dr. Stacy Sims?

  And you'll actually improve your running more so than if you're to run every day or every other day. Because if you're getting strong through full range of motion, then that feeds forward to better running economy. Then you can vary your pace without getting injured. But for people who are running every day, and they're shuffling, and they're getting stronger in their strong muscles and weaker in their weak muscles, then it perpetuates this.

• 58:02Dr Natalie Crawford?

  And they're in my clinic. Yeah.

• 58:03Steven Bartlett?

  People are very keen on doing marathons and half marathons at the moment, and got a couple of friends that are doing a lot of marathons at the moment, and they're very, very, very skinny.

• 58:13Dr Natalie Crawford?

  Oh, welcome to my world of Texas.

• 58:15Steven Bartlett?

  Yeah. Is that healthy? I'm not even sure if that's the right question. One can judge from just looking, but being extremely skinny in that regard, being that sort of marathon runner physique.

• 58:26Dr Natalie Crawford?

  There are some that are naturally predisposed to that. Right? So naturally predisposed, having really good running economy, running biomechanics, having a leaner body. And this is what we were talking about the Olympics earlier, where you can see the ideal body type for that particular sport. And then there are those like me who build muscle naturally. It's pretty easy. So I'd never be a skinny little runner.

• 58:48Dr. Stacy Sims?

  And my running economy is a little bit off because of where I build muscle versus not. So not everyone is meant to be a long distance runner. And there are some that are meant to be long distance runners. So if we're talking about your friends who are like super skinny, are they economically viable for being a long distance runner? Possibly, but we also have to look, are they male or female? What is their injury rate? What is their fueling? And then for me, I'd want to see the DEXA of the women that are just training long distance and super skinny. Because most of the time we see a higher visceral fat in, um, in and around the organs as we're talking about.

• 59:28Dr. Stacy Sims?

  Even though on the outside like super lean, but they have a really high percentage of visceral fat because of the inflammation. The low energy intake and most likely estradiol suppression.

• 59:40Steven Bartlett?

  And that's the skinny fat thing you, you talked earlier. Is, is there an evolutionary lens on this? I always think about this when we're having these conversations, like what, what used to happen thousands of years ago?

• 59:49Dr. Stacy Sims?

  We talk about the evolutionary biological theories and there are a lot of sociologists that will counter what I'm getting ready to say. So I'll apologize in advance. We look at original hunter gatherer type communities. The male body was designed to go out to find the calories. The women body was designed to stay and take care of the offspring and make sure that home was set. If it was low calorie, menstrual cycle would stop because you didn't want to reproduce in a time of low calories. Body fat would come on because there weren't a lot of calories.

• 1:00:21Steven Bartlett?

  And so the equivalent in the time now is that I'm not eating enough or I'm burning more than I'm consuming?

• 1:00:26Dr. Stacy Sims?

  Exactly.

• 1:00:27Steven Bartlett?

  So I'm in a calorie deficit in some way.

• 1:00:28Dr. Stacy Sims?

  Exactly.

• 1:00:29Steven Bartlett?

  Okay.

• 1:00:29Dr. Stacy Sims?

  An energy deficit. So with the male body, and we see this, their brain and hypothalamus is not as sensitive to those nutrient deficits as much as a woman's body, because we have menstrual cycle, menstrual cycle function. A man will lean up and get more cognitively focused in times of low calorie intake. So this is what we see with fasting data and we see with restrictive diets. And that was, we need to bring it back to that biological lens, low calorie, I have to go find the calories. I have to be fit to go find the calories, low calories. I need to not have to eat as much, so I need to store fat and I can't have a baby because we don't have enough calories.

• 1:01:10Steven Bartlett?

  And then stress?

• 1:01:12Dr. Stacy Sims?

  When we add modern stress onto that, that's a comprehensive addition of cortisol and addition of inflammation, and that also perpetuates body fat.

• 1:01:21Steven Bartlett?

  I mean, like, stress 10,000 years ago would have been like a lion.

• 1:01:25Dr Natalie Crawford?

  Oh, yeah. It's a lion. But it's episodic. Yeah. Right? We had stress, and this is a natural stress response. We have to have them to survive. Right. These were episodic. Right. Stresses. Well, and your hormones would change for a very specific purpose that you would then go do. Your body would free up glucose from your liver. You're getting it ready in your bloodstream so you can go run from the lion. Yep. And then things would shift back to normal. And what's happening with chronic stress is you're getting all the hormone shifts because your body's really getting ready for the lion, except it's just that bad meeting you had. Yep. And then you're just sitting there longer, and you're not using that glucose up. Exactly. Exactly.

• 1:02:01Steven Bartlett?

  Are women increasingly overtraining?

• 1:02:03Dr. Vonda Wright?

  I think the problem in this country is not, maybe in the women who are really intentional, maybe there are some that are over-exercising, but if we look at a population, nobody is exercising enough.

• 1:02:17Dr Natalie Crawford?

  Exactly.

• 1:02:18Dr. Vonda Wright?

  I mean, I would take, people ask me all the time, "Tell me the first thing people need to do." I'm like, "I'll take anything." I mean, I'll take getting off the couch with any method, whatever makes you happy.

• 1:02:28Dr Natalie Crawford?

  I'll say, "Get off the couch and do 10 air squats. Thank you."

• 1:02:31Dr. Vonda Wright?

  That's enough. That's enough.

• 1:02:32Dr Natalie Crawford?

  Just raises and straight.

• 1:02:33Dr. Vonda Wright?

  So, so in the crowd that's like, "I'm going to invest in my health every day," that is not the majority of people.

• 1:02:41Dr Natalie Crawford?

  Yeah. That's my bubble. Yeah, but the people who listen to your show, though, I think they want to. might be a different demographic, we have to acknowledge, right? Than population of America. I mean, like, a lot of people who've listened to your show, Stephen, are interested in health and their body and achieving certain goals. And so certainly, you know, I have practiced fertility in North Carolina and in Austin, and I see a completely different patient population, you know, in Austin, Texas, which is a very fit area. Women are constantly overtraining. But to Stacy's point earlier about this maybe evolutionary what happens.

• 1:03:18Dr Natalie Crawford?

  Women go into this hypothalamic dysfunction even before it's what we call like amenorrhea. Hypothalamic amenorrhea is essentially where the brain, where the hypothalamus is shuts off, says can't reproduce right now, XYZ reason, no FSH and LH are coming out, you're not ovulating, you're not making estrogen, you're not going to get pregnant.

• 1:03:37Dr. Mary Claire Haver?

  So you're more likely to survive.

• 1:03:38Dr Natalie Crawford?

  Yeah, so it's a survival mechanism.

• 1:03:40Dr. Mary Claire Haver?

  Pregnancy is dangerous as in hunter gatherers.

• 1:03:43Dr Natalie Crawford?

  But their state, modern medicine acts like you're perfect or it's turned off. And the reality is there's all these shades of gray in between where these different chronic stressors and your insulin resistance and your inflammation and your over exercising and your under fueling come in and make it so the hypothalamus is not responding correctly. And that's what we're trying to get people to intervene there before it gets too bad. And I see a large number of women who do fall into that zone where they are trying their hardest to be healthy, but what they are choosing to do is actually having a negative impact on their hormonal health and how their brain is interpreting their hormones. And you, it's very rare to see that in a man.

• 1:04:25Dr Natalie Crawford?

  Meaning the number one reason why I will see low testosterone is purely because many men are taking testosterone or because of other exogenous factors like marijuana use. It is very rarely my brain is not sending out the signals to cause my testicles to make testosterone.

• 1:04:41Dr. Stacy Sims?

  I like to frame it where women are under recovering, not overtraining. So for under recovery, then it makes it more acceptable to fuel. And I always want to bring it back to, it doesn't matter, like because I come from high performance, I'm going to use those words where it's like you're not recovering enough. We want to focus on recovery on these days. We want to make sure that you're eating and fueling around. So it's never overtraining, it's always under recovery.

• 1:05:07Dr Natalie Crawford?

  But the balance is wrong, they're not recovering.

• 1:05:08Dr. Mary Claire Haver?

  So what do you say to all the voices on social media that are just yelling at mostly women and telling them it's just a matter of willpower and you don't have the body composition you deserve?

• 1:05:20Dr. Stacy Sims?

  Well, you swipe left and don't talk to those people.

• 1:05:23Dr. Mary Claire Haver?

  But that's me, right? But I'm talking to the woman in Ohio who's feeling defeated and stumbles across someone screaming at her on the internet that her body composition that she's not happy with is her fault.

• 1:05:35Dr. Stacy Sims?

  I hate that because it's a construct of society, right? Especially Western society. This is where we have to educate. It's not your fault. These are the things that have come into play and lined up to create this situation. But now we have tools to offer you to take one step out of that situation. And let's see how many more steps we can get you away from the situation to improve your health.

• 1:06:00Steven Bartlett?

  And are the rules of exercise slightly different once you've entered perimenopause?

• 1:06:05Dr. Stacy Sims?

  So this is where we really need to look at how we can use exercise and some environmental stress to create a really strong adaptive stress and a really strong recovery stress.

• 1:06:17Dr. Mary Claire Haver?

  Stacy, can you explain adaptive stress? Because I'm thinking of the 10,000 people who follow me who will be like...

• 1:06:22Dr. Stacy Sims?

  Who have no idea what adaptive stress is. So if I go and I do some resistance training, some heavy lifting, I want to create a stress on my body that's gonna then have a signaling cascade to repair the muscle in a stronger way than when I first went in.

• 1:06:41Dr. Mary Claire Haver?

  Because lifting the muscle damages the muscle?

• 1:06:43Dr. Stacy Sims?

  Yes, and it creates a series of feedback mechanisms that make it repair stronger than when you first went in. So that's an adaptive stress. And we're looking at what levels of stress we can put, so it's a training stress, or what levels of stress we can use through exercise to really, really create an environment that improves our health. So if we talk about sprint interval training, the 30 seconds on and the two to three minute recovery, the reason why you want that super high-end stress of our heart rate is it then creates an eventual epigenetic change. So it's that environment that's going to create a change within the muscle that's

• 1:07:25Dr. Stacy Sims?

  going to allow that Glut4 protein that I mentioned earlier to open up and have glucose come in, reducing insulin resistance. Also with that really high, high heart rate, we're having a lot of stress on the muscle that's going to release some myokines, which are... Little hormone signals that then will go to the liver and say, wait a second, we don't need to store visceral fat. We need to create non-estrogide fatty acids, which can then go into our skeletal muscle to be used in the mitochondria as fuel. So we want to have the stress that's strong enough to create these cascades of feedback mechanisms to improve our overall health. If we stay in that moderate intensity zone,

• 1:08:06Dr. Stacy Sims?

  we aren't creating a strong enough stress to create that signaling. What are we doing? We are exacerbating inflammation. We're exacerbating cortisol. Now cortisol isn't the demon, but when we have an elevation of it, and especially in perimenopause, when we're sympathetically driven and we already have a higher level of baseline cortisol. If we are continuously in this moderate intensity zone, we never get a signal to allow that to drop. So if we're looking at polarizing, which is top, top end and low recovery end, then with the top end, we get the signal cascade of improving body comp, improving insulin sensitivity, as well as getting growth hormone and testosterone responses,

• 1:08:52Dr. Stacy Sims?

  which then feed back to drop cortisol.

• 1:08:53Steven Bartlett?

  So am I right in thinking the solution, if I'm perimenopausal, is to do high intensity interval training for short periods of time?

• 1:09:01Dr. Stacy Sims?

  So we look at the quality of the training, not the volume of the training. So if we're in our reproductive years, then yes, you can do the moderate intensity stuff because you have estrogen and some of our other hormone feedback signals that are going to drop cortisol. It's going to allow your body to recover and repair.

• 1:09:19Steven Bartlett?

  And when you, what makes quality training? What is quality training?

• 1:09:22Dr. Stacy Sims?

  So this is your polar, so you have a very specific session that you're going to do. So for Vonda, it's your 30 seconds on as hard as possible, two to three minutes recovery. You do that four times, that's your session.

• 1:09:33Steven Bartlett?

  Okay, I'm going to try and summarize this. See if, this is a test. See if I understood all of this stuff. So if I do a lot of volume, but I play in that sort of medium intensity range, I'm basically just like stressing out my body in all the worst ways.

• 1:09:48Dr. Stacy Sims?

  Exactly.

• 1:09:49Steven Bartlett?

  Like the inflammation, it's just not good for my body necessarily. If I don't do vigorous enough exercise, then that's also bad because nothing's gonna break and therefore build. It's, nothing's gonna adapt, nothing's gonna grow.

• 1:10:04Steven Bartlett?

  If I do it for long periods of time, really anything for long periods of time, that's also stress. But the key thing to do is to do shorter, higher intensity exercise that will cause my body to adapt, but won't put it into that inflamed stressful state.

• 1:10:22Dr. Stacy Sims?

  And you also have to pepper in some lower intensity work. So this is your

• 1:10:27Steven Bartlett?

  Flexibility.

• 1:10:28Dr. Stacy Sims?

  Mm hmm. So that you have recovery, you're getting blood flow circulating, you're tapping into some mitochondrial work so that you are still getting benefit of exercise, but it's not in that modern intensity. So that's what we mean by polarizing. So if we were to talk in like the zones talk that everyone talks is out there, right? We're looking at

• 1:10:48Steven Bartlett?

  What is zones?

• 1:10:49Dr. Stacy Sims?

  So if we're talking about heart rate and the way that your body works, we have zone one, which is just sitting around, you know, like you're

• 1:10:56Dr. Vonda Wright?

  Yeah.

• 1:10:56Steven Bartlett?

  We're in zone one.

• 1:10:57Dr. Stacy Sims?

  We're in zone one. Zone two is the neuroscience kind of thing where you're like, let's, let's work in the zone two area where we're working.

• 1:11:07Steven Bartlett?

  I was in zone two when you were talking about menstrual cycle.

• 1:11:09Dr. Stacy Sims?

  Yeah, there you go. That's it. A little elevated. Your, your heart rate's elevated, you still a little bit have a conversation. For women, it's good for recovery, stress release. For men, it's good to improve metabolic flexibility. We're looking at zone three, four. That's the area you want to stay out of unless you're specifically training for something that requires you to be there. So that would be your half marathons, your endurance races, that kind of stuff.

• 1:11:35Steven Bartlett?

  Everyone wants to stay out of zone?

• 1:11:38Dr. Stacy Sims?

  Three, four.

• 1:11:40Dr. Vonda Wright?

  During training.

• 1:11:41Steven Bartlett?

  Oh, okay. Fine. Cause that's the medium range, right?

• 1:11:43Dr. Stacy Sims?

  Yeah, that's medium range.

• 1:11:44Steven Bartlett?

  So you want to jump into zone five, hang around for

• 1:11:47Dr. Stacy Sims?

  Five, six. Yeah.

• 1:11:48Steven Bartlett?

  Okay, a couple of minutes and then get out of there.

• 1:11:50Dr. Stacy Sims?

  Yeah.

• 1:11:50Dr. Vonda Wright?

  But in a week, this is

• 1:11:52Dr. Stacy Sims?

  Yeah, it's

• 1:11:52Dr. Vonda Wright?

  Let's just be clear. So Two to four days a week, you should be lifting progressively to lift heavy, meaning heavier weights, fewer reps, right? One compound lift a day, plus the augmentative lifts that go behind it, right? So you're warming up first, then you're gonna do one lift, and then you're gonna do your jumping or your balance work. The other days of the week, you will do preferably low intensity doing anything. Walking briskly down the New York street could count as that. It's continuous motion.

• 1:12:30Dr. Vonda Wright?

  And then, a couple days a week, add in your sprint intervals, your really high zone five, six, high intensity. And then, when you've got that, you can add in your four by four VO2 max on one of the other days, because it sounds like a lot, but when I work with non-pro athletes, I layer on behaviors.

• 1:12:56Dr. Stacy Sims?

  Absolutely.

• 1:12:57Dr. Vonda Wright?

  Because if I say, "All of this at once,"

• 1:12:59Dr. Stacy Sims?

  Yeah.

• 1:13:00Dr. Vonda Wright?

  Nobody's gonna do anything.

• 1:13:01Dr. Stacy Sims?

  I always describe it as, we have these pillars, right? First, we have to nail sleep. Doesn't matter who you are, you have to-

• 1:13:07Dr. Mary Claire Haver?

  Same.

• 1:13:08Dr. Stacy Sims?

  Because you cannot-

• 1:13:09Dr. Mary Claire Haver?

  Sleep is non-negotiable.

• 1:13:10Dr. Stacy Sims?

  Yeah, you cannot invoke any kind of metabolic or body composition change without adequate sleep. Also, improve stress resilience. Then we look at nutrition and physical activity. The behaviors that go with both of those are somewhat independent. You have some people that are more motivated to do physical activity, and some people are more motivated to change nutritional habits. Most of the time, they're two different personalities. So we have to look at what comes next. And then we also have, which isn't lesser importance, but often neglected, is the mindfulness and community. So this is being out in nature, it's connecting with friends, might be going to group exercise class, it might be just having coffee. But that is really, really important for parasympathetic and whole, like, whole being life.

• 1:13:53Dr. Mary Claire Haver?

  Stress response.

• 1:13:54Dr. Stacy Sims?

  Exactly.

• 1:13:55Dr. Mary Claire Haver?

  So there's a new book out, coming out, called Joyce Ban. I don't know if you've spoken with her. So she's a geriatricologist and works with the very elderly, and she has a very specific, you know, what determines who's gonna kill it in that last decade of life? And- That community part, using your brain, you know, having interactions with human beings seems to be the key. And if you don't keep that going through this 40s, 50s, 60s, when you get to 70 and 80, you're not going to have a great end of your life.

• 1:14:26Steven Bartlett?

  And what about the last phase then? So if someone's post-menopausal, does their exercise recommendations change at all?

• 1:14:33Dr. Mary Claire Haver?

  We like to start the habits early and continue them through. If you haven't started, it's not too late. As we're seeing like with Liftmore and some other of the older age resources coming out, it's never too late to start. We just have to be very careful of how you start to have support and phase you into these different exercise modalities.

• 1:14:52Steven Bartlett?

  Is it the same exercises though?

• 1:14:55Dr. Mary Claire Haver?

  Meaning?

• 1:14:56Steven Bartlett?

  You know, the three days a week, the mobility, the strength.

• 1:14:59Dr. Mary Claire Haver?

  I am firmly post-menopausal and I am doing all these things.

• 1:15:03Dr. Stacy Sims?

  But it's different, different. People always ask me, what does heavy lifting mean?

• 1:15:07Dr. Mary Claire Haver?

  Right, it's relative.

• 1:15:08Dr. Stacy Sims?

  It's relative. My heavy is not going to be Stacy's heavy. Or I should say it the other way. Stacy's very heavy is not going to be my heavy.

• 1:15:16Dr. Mary Claire Haver?

  In Liftmore, they just, the authors describe the one, the one rep max. And so one rep max is like safely, what is the heaviest you can do one rep? You know, so for a bicep curl, what is the heaviest weight I can do? One to fail, you know, I'm going to fail after this one. And for me, that was about 20 pounds.

• 1:15:34Dr. Stacy Sims?

  With good form.

• 1:15:35Dr. Mary Claire Haver?

  Exactly, safely with good form. And so I could nail 20. And so then they took them down to about 70, 80% of that, um, which for me was about 15, 16 pounds. So that you can usually do about five reps before you hit failure. And that is what they consider lifting heavy. And that seemed to really resonate with my followers to understand what that meant.

• 1:15:58Dr. Stacy Sims?

  And there are so many women that underestimate their strength. See them and they gravitate towards the 10-pound dumbbells. It's like, put that away, go to the next one. Do a couple of lifts with that. And then ideally, I want you to put that away and pick up the next one. Because that's going to challenge you. Because women have been so conditioned to do 10 to 15 reps to get, quote, toned, and not really put in the work they need to, to build muscle and to get the benefit out of strength training. And I'm always telling women, you're underestimating yourself in so many facets. Don't cheat yourself with the strength training as well.

• 1:16:34Dr. Vonda Wright?

  Because people have to remember what we're, what we're training for now. It's different than, I had a woman recently say, I was taught to do biceps curls, five pounds, 30 times. Well, after 30 times, not only are you bored, but you'll probably be at failure 30 times. That will build endurance. I am training to be as strong as possible. And when I'm, when I have strength down, then I start playing with tempo so that I could build, replace some of the explosive muscle fibers that I'm going to lose over time.

• 1:17:07Steven Bartlett?

  To your point, Wanda, I have just been writing my book in Cape Town, as I told you before we started recording. And one of the studies that I read about while I was writing the book was a study done by some, a guy called Hal Hirschfield and his colleagues, where they asked, they put people in these MRI scanners, and they asked them to think about a famous celebrity. And then they asked them to think about themselves today. And then they asked them to think about themselves in 10 years' time. And in 10 years' time, the same brain regions lit up as if they were thinking about the celebrity, which kind, kind of led them to conclude that in our brain, we almost see our future selves as a bit of a stranger.

• 1:17:44Dr. Vonda Wright?

  Yes, that's right.

• 1:17:45Steven Bartlett?

  And so when we think about long-term planning, this is in part why a lot of this advice is often most effective when it's put in the context of like, short-term performance or cognitive benefits. Because we really do struggle to like, care about ourselves at 90.

• 1:17:59Dr. Vonda Wright?

  Yeah.

• 1:18:00Steven Bartlett?

  And we, I think we all kind of think we can just figure it out later.

• 1:18:03Dr. Mary Claire Haver?

  I think what's different for women, especially in menopause, is because we're also taking care of our parents.

• 1:18:08Dr. Stacy Sims?

  Yep.

• 1:18:08Dr. Mary Claire Haver?

  In so many ways, you know, we're in this like, raising kids, going through our own hormonal upheaval, and then watching our mothers, our grandmothers, our aunts age. And we, the way society is set up, women become the caretakers of their parents, generally the oldest daughter. And I have to give full credit to my sister, who lives in the same town as my mom and is a nurse. So she really is bearing the brunt of taking care of mama, because I'm living this life. So thank you, Leah, if you're watching. It is such a tremendous stress, you know, and so. Our motivation, my sister and I, is like, we don't want to do this to our daughters.

• 1:18:42Dr. Stacy Sims?

  Yeah, exactly. The other thing I want to bring in is the brain health component, right? We talk about Alzheimer's and dementia. And one of the reasons I really prefaced doing high intensity work is the lactate production. Because we're finding more and more research coming out showing that part of the development of dementia and Alzheimer and the plaque is a misstep in brain metabolism. So when we're looking at brain metabolism and the brain uses a lot of glucose, it also uses lactate. Now, for women, we have less of the glycolytic or lactate producing fibers, and we tend to lose those with age. Men are born with more, tend to hold on to them more, so it's not necessarily as big an issue for lactate production.

• 1:19:24Dr. Stacy Sims?

  Men need to spend more time in the low intensity, being able to produce more of our fat burning capacity. But for women, doing that high intensity work and being able to produce lactate to then allow the heart in the brain to use that preferential fuel feeds forward to reducing the misstep in this brain metabolism component that occurs. And it's such a sex difference. We're seeing a change in glucose metabolism in and around perimenopause into menopause. So it's that lactate production that I, is kind of the offshoot of the high intensity work that's super important for brain health as well as.

• 1:20:04Dr. Mary Claire Haver?

  When you look at glucose metabolism in the brain, I'm talking specifically coming out of Arizona and from Lisa Musconi's work, and they looked at glucose utilization in the brain, especially the forebrain, through the transition. It's wildly different based on what phase of perimenopause, menopause, and postmenopause that they're in. And it's absolutely astounding, and they're seeing patterns that can give clues that may be the women who are headed towards the dementia route versus those who aren't.

• 1:20:35Steven Bartlett?

  And women are significantly more likely than men to develop dementia and Alzheimer's, largely because they. Have certain unique biological risk factors and also because they live longer.

• 1:20:44Dr. Stacy Sims?

  And the sociocultural component, I keep bringing it up.

• 1:20:47Dr. Mary Claire Haver?

  Yeah, stress.

• 1:20:47Dr. Stacy Sims?

  Yeah, but also if we're looking at women who are eighty, ninety years old now, their upbringing to this point is completely different than ours, meaning that the job availability and the brain stimulation they had when they were in their forties, thirties, forties, fifties, completely different than what we have now.

• 1:21:05Steven Bartlett?

  Better or worse?

• 1:21:06Dr. Stacy Sims?

  Worse, so they didn't have necessarily opportunity to be scientists, lawyers, medical doctors. So they didn't have as much stimulation of brain and implications on that neuroplasticity. So we're seeing a higher episodic issue of dementia and Alzheimer's in older women now because they didn't have the same lay down effect that we have now as fifty year olds, forty, fifty year olds and the stimulus we have for neuroplasticity.

• 1:21:36Steven Bartlett?

  Oh, so.

• 1:21:37Dr. Mary Claire Haver?

  Like you're laying down brain pathways and neural fibers.

• 1:21:40Dr. Stacy Sims?

  So neuroplasticity.

• 1:21:41Dr. Mary Claire Haver?

  Think about it like the bone, but you're creating pathways in your brain to make you healthier.

• 1:21:45Dr. Stacy Sims?

  Less, more resilient.

• 1:21:46Steven Bartlett?

  More resilient.

• 1:21:47Dr. Mary Claire Haver?

  To dementia.

• 1:21:48Steven Bartlett?

  But they're also gonna have more stress.

• 1:21:49Dr. Mary Claire Haver?

  Built a stronger brain younger.

• 1:21:51Steven Bartlett?

  Are they not gonna have more stress if they're working?

• 1:21:53Dr. Mary Claire Haver?

  Maybe.

• 1:21:54Steven Bartlett?

  More hours and.

• 1:21:55Dr. Mary Claire Haver?

  Fascinating study, and this one shot me out of a cannon emotionally, was if you choose to become a caretaker of a parent with dementia, you have a sixty percent increased risk. Now, there's a genetic component, but when they took the genetics out of it and they feel like it's the stress of caregiving for that parent, you are signing your own death warrant because now you are increasing your risk of death.

• 1:22:19Steven Bartlett?

  Because, yeah, because I'm right in thinking that women are still both caregiver and now in the corporate world.

• 1:22:25Dr. Stacy Sims?

  Yes.

• 1:22:25Dr. Mary Claire Haver?

  Yes, that's right.

• 1:22:27Steven Bartlett?

  So it's both.

• 1:22:28Dr. Stacy Sims?

  Yeah. Stress from both ends.

• 1:22:32Dr. Mary Claire Haver?

  Lactate production for the win.

• 1:22:34Dr Natalie Crawford?

  But you have to have an active plan to combat this.

• 1:22:37Dr. Mary Claire Haver?

  Yeah.

• 1:22:37Dr Natalie Crawford?

  We're not going to live in a world that is stress free. If you're a woman in the world, you are likely to have a caretaking role in some fashion, even if you are chasing other dreams when it comes to professionally. Building good brain pathways is wonderful as far as a way to help start from a higher standpoint before you have brain loss. However, we've, just like we've said on these other tangents, the brain is that too. We need to think about active ways we're going to combat what is happening in today's world naturally. And some of the factors are modern society that put us into this pro-inflammatory state. But we need to think about making lactate, you know, what's important for us. And it really is a plan.

• 1:23:20Dr Natalie Crawford?

  This whole, I'm going to figure it out when I'm 90 and the problems in front of me is too late for these medical problems.

• 1:23:26Dr. Mary Claire Haver?

  So, and back to your point about neuroplasticity, we're not reading as much. We're on our phones. And so.

• 1:23:34Dr Natalie Crawford?

  Not in my house.

• 1:23:34Dr. Mary Claire Haver?

  Yeah. And so as, as a culture, there's, there's this worry that all this time on the phone and these dopamine hits and, but not creating stories in your head and, and reading for pleasure at night, you know, a lot of women are on their phones now before bed rather than developing that neuroplasticity that we get from storytelling.

• 1:23:56Steven Bartlett?

  I did something at 24 years old that has had a profound impact on my life. I set myself the challenge of posting every single day on my social media channels. And at the time I was doing it to grow my following, but it had this profound impact on my life and two remarkable things happened when I did that. I managed to learn faster because every single day I'm capturing what is happening to me and trying to distill it down into something that I can share with the world. But more remarkably, it led me to building a following of many millions of people and that's the basis that I used to launch the Diary of a CEO. And that's why I want to tell you about our sponsor today, Adobe Express. They are the platform that I use to make all the posts across my LinkedIn and across my Instagram. It's a couple of clicks and you don't need to be an expert. And that is why I love using it because I'm not an expert in graphic design.

• 1:24:39Steven Bartlett?

  It's accessible to use for all of us, even if we don't have the technical prowess to design great things. So if you want to start compounding both your reach and your knowledge like I did at 24 years old, then head to adobe.ly/steven and get started with Adobe Express. That's adobe.ly/steven.

• 1:24:59Steven Bartlett?

  The next question that came in from the audience, we asked a thousand women to submit their questions. The next one is, what's the best and healthiest way for a woman to lose weight?

• 1:25:10Dr. Vonda Wright?

  Lift weights.

• 1:25:11Dr. Stacy Sims?

  Lift weights.

• 1:25:11Dr. Vonda Wright?

  And eat.

• 1:25:12Dr. Stacy Sims?

  And eat, yes, absolutely. And you could have a very slight calorie deficit towards the end of the evening.

• 1:25:19Steven Bartlett?

  Running?

• 1:25:22Dr. Stacy Sims?

  As a way of burning calories? The problem is, people think that they can out-exercise a bad diet, and you can't.

• 1:25:29Dr Natalie Crawford?

  Composition of your diet matters immensely.

• 1:25:31Dr. Mary Claire Haver?

  And I hate calling it lose weight. I now call it recomposition.

• 1:25:35Dr. Vonda Wright?

  Yeah, but let me put it in context. Yeah, go run. You're gonna burn 100 calories a mile. Three Girl Scout cookies, three Thin Mints, US favorites, is 180 calories. So you have to run two miles to eat three cookies. Most of us, if you're gonna eat cookies, don't eat three Thin Mints, you eat the whole sleeve, right? To your point, it is impossible to out-exercise food unless you're a high-level athlete.

• 1:26:04Dr. Stacy Sims?

  And even then, no.

• 1:26:05Dr. Vonda Wright?

  Who's 10,000 calories.

• 1:26:06Dr. Stacy Sims?

  Even then, no, because we look at diet composition, and we see that endurance athletes who use a lot of high sugary type carbohydrates, like the gels and the sports stuff, they've interrupted their gut microbiome so much that they have...

• 1:26:20Dr Natalie Crawford?

  Sugar alcohols.

• 1:26:20Dr. Stacy Sims?

  Yeah, well, it's not even that. It's the phylate change. We're seeing a decrease in the diversity, even though they're exercising, and we see that exercise increases the diversity of the gut microbiome. It's what they're eating during the training with the heat and hypoxic stress.

• 1:26:36Dr. Vonda Wright?

  Wow.

• 1:26:36Dr. Stacy Sims?

  That is creating the growth of the ferromicudins phylate that's associated with obese outcomes.

• 1:26:43Steven Bartlett?

  So that's a...

• 1:26:44Dr. Vonda Wright?

  It changes the gut.

• 1:26:45Dr. Stacy Sims?

  The gut bacteria, yeah.

• 1:26:46Dr. Vonda Wright?

  Yeah.

• 1:26:47Steven Bartlett?

  If they are...

• 1:26:49Dr. Stacy Sims?

  So, we have this misconception that if you're an elite athlete and you're burning all these calories, then you're just eating to fuel, right? But it's not. It's the quality of the diet. If we want to perform well, whatever performance means, if you're an Olympic athlete down to recreational person who just wants to accomplish a 5K, the composition of your diet is immensely important.

• 1:27:12Steven Bartlett?

  What about Zempec? Everybody seems to be on a Zempec GLP-1s.

• 1:27:15Dr Natalie Crawford?

  I prescribe it. And our clinic is all perimenopause and menopause. And so we always start with, let's see how you do with lifestyle changes first. So we give that three to six months. When they come back, every time they come back, we're doing another body composition change. For probably 50% of the patients, lifestyle plus or minus HRT. Their, their body composition changes, they're happy, they're health, you know, they're much healthier. Everything's moving in the right direction. So now we're left with the people who are doing all the things.

• 1:27:45Steven Bartlett?

  This isn't the typical story of people that start a Zempec though. They see it on Instagram and then a week after I'll be at their house and I'll be like, wee wee. And they'll tell me, oh yeah, I'm on a Zempec. And it's really, it's usually just someone sees it online, they hear it on a podcast and they're on it within a couple of days.

• 1:28:00Dr. Mary Claire Haver?

  The access is getting easier, the price is coming down and there is for any medication, there are risks, there are benefits. And there's ways that will promote health and with any medication, you can not promote health if you give.

• 1:28:14Dr Natalie Crawford?

  I mean, GLP-1s can be revolutionary for certain people. A lot of people are not training for a 5K, let alone anything else. And we know if we go very simply, fat cells, right? They make a different type of estrogen, they're inflammatory, you have insulin resistance. And all of this sets you up at a deficit to say, I want to get healthier. It, for women, we'll say you have PCOS, who already have a predisposition for insulin resistance. They have a harder time losing weight because now they're also storing visceral fat. We know they get on this cycle with hormonal change. You know, being on Ozempic allows them to lose weight and combat insulin resistance in a faster way than they've ever been able to do before.

• 1:28:55Dr Natalie Crawford?

  And especially when it comes to fertility and you're on a timeline, that can be really revolutionary. When you lose weight because that estrogen decreases, many women with PCOS, if they were overweight, will start ovulating again because that suppression from the additional estrogen is gone. And their inflammation markers go down, their insulin resistance decreases. So there's a subset of people who have found their life changed by them. And we never want to discredit that. Many people. About difficulty losing weight, chronic medical conditions have been able to reverse them. And this has been a tool in the toolbox.

• 1:29:31Steven Bartlett?

  Because about 70% of Americans would fit in that category of chronic health conditions, difficulty losing weight.

• 1:29:36Dr. Mary Claire Haver?

  Seventy three percent right now are overweight or obese.

• 1:29:39Steven Bartlett?

  So should 73% of Americans be on GLP-1?

• 1:29:42Dr. Mary Claire Haver?

  And it's higher in women.

• 1:29:44Dr Natalie Crawford?

  Well, we always, one common thing is having tools in the toolbox and being able to know when to use them, when to offer them. Just like when we have the HRT discussion, we don't want to see people, say, women for this discussion, not being offered a therapeutic option because, or not choosing it out of fear.

• 1:30:01Steven Bartlett?

  Well, when I hear that it's going to help me lose weight and I've got two options, I can go out and lift all these weights, Stacy, and I can, which, you know, one day I don't, yeah, it's hard, isn't it? Go to the gym, have to put my shoes on, all these, all these things, or I can take this injection.

• 1:30:16Dr. Stacy Sims?

  And lose all your muscle and lose your bone and end up like the little floating figure in Wally movies that I've talked about before. Right? And that's, that's my fear of just blanket people use.

• 1:30:29Dr Natalie Crawford?

  You're also, whether you mean to or not, giving the illusion that, you know, willpower is all you need to lose weight.

• 1:30:37Dr. Stacy Sims?

  Right.

• 1:30:37Dr Natalie Crawford?

  By what you said, right? I can either do these hard things or I can choose this medication, which appears to be the easier way out. And two things can be true at once. People can work extremely hard. Maybe they don't understand exactly what they should be doing. And that's part of what we're trying to change the discussion on. But reversing some metabolic change, even initially, can make a big difference in their game plan, but you will lose body weight on these medications. And so you have to have somebody, you know, guiding the ship. I think what we all don't love is the access without oversight, meaning nobody's helping you say, how are you not losing muscle? How are you doing this in a safe fashion? You can just text somebody on an app and suddenly get medication.

• 1:31:20Dr. Mary Claire Haver?

  And have the medication ship to your house. You know, in our clinic, it is an hour long. Now they're coming in to discuss the GLP-1 option. It is an hour long visit. Of risks, benefits, side effects, protein intake, resistance training, mandatory. We will follow your bone density. We will follow your bone mass, I mean, your muscle mass. You know, we have these scanners.

• 1:31:40Dr. Vonda Wright?

  These are great.

• 1:31:40Dr. Mary Claire Haver?

  Available. And we're not going to get to a number on the scale and sacrifice your long-term health. And my patients are drinking the Kool-Aid. They're coming in, they've found, you know, they-

• 1:31:50Dr. Vonda Wright?

  They're coming to you for a reason.

• 1:31:51Dr. Mary Claire Haver?

  Yeah. And so I'm a little bit unique in my clinic in that I have a social media following and people kind of watch a few things before they come see me so they know my, they're not shocked by me giving this advice because I give it all day on social media.

• 1:32:03Steven Bartlett?

  So if you give them the Ozempic, but they still don't go to the gym, they still don't do anything else?

• 1:32:08Dr. Mary Claire Haver?

  Then we'll stop giving it to them. They won't be healthy. And they know that. We've talked to them about that. We've explained it on the front end, that this is a tool in your toolkit, because we can see their muscle mass. We won't renew the prescription if they've lost the muscle.

• 1:32:21Dr. Vonda Wright?

  So if you are losing weight and not lifting and eating enough protein on Ozempic or any way else, and you do a body composition, you may see total weight lost, you will see pounds of muscle loss, you may see body fat percentage loss. But if you do this correctly with enough protein in your diet and lifting weights, the amount of muscle loss will be very small versus amount of fat loss. So we know we're going to lose a little muscle, but you can't lose eight pounds of muscle.

• 1:32:57Dr. Mary Claire Haver?

  Right.

• 1:32:58Dr. Vonda Wright?

  Right? So we can tell.

• 1:32:59Dr. Mary Claire Haver?

  And I give them the hard numbers, like 10% is acceptable. We're going over that. We're getting into the danger zone. We're going to cut back on your dose. We're going to, you know, but they commit to the work on the front end.

• 1:33:11Steven Bartlett?

  I think that's the important point is that these GLP-1 antagonists don't burn your fat. They burn, they stop you eating as much.

• 1:33:20Dr. Vonda Wright?

  They stop their satiety.

• 1:33:21Steven Bartlett?

  Which is going to mess up, which is going to reduce everything. Because I was thinking about myself, I was thinking, well, I go to the gym every day. I'm going to keep going. So maybe if I had a little bit of Ozempic or whatever it's called, then it would burn my fat, but actually that's not what's going to-

• 1:33:32Dr. Mary Claire Haver?

  It's not, no.

• 1:33:33Steven Bartlett?

  It's just going to stop me eating, which is going to reduce my muscle, my burn.

• 1:33:36Dr. Mary Claire Haver?

  Right. Goodbye biceps.

• 1:33:38Dr. Vonda Wright?

  Yeah.

• 1:33:38Dr. Mary Claire Haver?

  That's the, that's the thing. It's like-

• 1:33:40Steven Bartlett?

  Then I'll lose my subscribers and-

• 1:33:42Dr. Mary Claire Haver?

  Yeah, that's why they're nice. Exactly, exactly.

• 1:33:46Dr. Stacy Sims?

  Yeah.

• 1:33:47Steven Bartlett?

  Okay, that makes sense. So to this person asking what's the best and healthiest way to lose weight, the response is stop eating the cookies and start lifting some weights.

• 1:33:55Dr. Stacy Sims?

  The eighty twenty rule, right? So eighty percent of the time you're on it, right? You're paying attention to a high quality diet. You are eating according circadian rhythm. You are doing the strength training, getting the good sleep. And then twenty percent is life. Where I'm going to stay up late, I'm going to have some wine or whiskey, I'm going to go out, I'm going to be on vacation. So you're not excluding all the fun things in life. If it comes to a point where you're like, I'm still not budging the needle, then maybe it's a ninety ten rule, or ninety percent of the time you're on it, and ten percent is the life factor. There's these hard and fast rules I've been accused of giving. I don't give rules. I give optimization ideas. So it's not following strict eighty twenty or ninety ten.

• 1:34:40Dr. Stacy Sims?

  It's what fits in your life. And if you're really motivated on losing weight, the first thing I tell people to do is ditch alcohol.

• 1:34:48Steven Bartlett?

  Everyone wants to lose the part on the belly.

• 1:34:50Dr. Stacy Sims?

  Yeah, sure.

• 1:34:51Steven Bartlett?

  Is there not like an exercise I can do just to burn the part on the belly?

• 1:34:54Dr. Stacy Sims?

  There's no exercise.

• 1:34:57Dr. Mary Claire Haver?

  So visceral fat's a little bit different. It's like a whole different organ. So, you know, when we talk about visceral fat, it has different drivers. You know, we drive fat to the intra abdominal cavity. It has, it creates a different cytokine. Subcutaneous fat is a storage facility. It is when we overeat calories, we will drive fat under the skin and it's kind of genetically determined. Females tend to gain about their hips and thighs. Okay. And actually, that hip and thigh fat is protective for cardiovascular disease in Perimenopausal women, not in men, but in women. And so it is, but when that fat shifts to the intra abdominal cavity, it starts, that fat is much more metabolically active than the fat under our skin, and it creates these proinflammatory cytokines. And then

• 1:35:41Dr. Mary Claire Haver?

  you end up in this negative feedback cycle of, you know, your liver starts becoming dysfunctional. Insulin resistance increases, that drives more fat to the Visceral cavity increases inflammation and it just goes on and on and on.

• 1:35:53Steven Bartlett?

  So I'll get liposuction.

• 1:35:54Dr Natalie Crawford?

  No, no, no.

• 1:35:55Dr. Mary Claire Haver?

  You can't liposuction.

• 1:35:56Dr Natalie Crawford?

  They're inside.

• 1:35:57Dr. Mary Claire Haver?

  That fat that's really inside the abdominal cavity is what we're talking about. That visceral fat, which is the worst kind.

• 1:36:03Steven Bartlett?

  But what about liposuction? Can't I just suck it out? People are doing all kinds with that fat.

• 1:36:06Dr. Vonda Wright?

  Under the skin.

• 1:36:07Dr. Mary Claire Haver?

  Under the skin you can, and that's an aesthetic decision.

• 1:36:09Steven Bartlett?

  The stuff under the skin.

• 1:36:11Dr. Mary Claire Haver?

  Oh, shh.

• 1:36:12Steven Bartlett?

  Liposuction it out? Is that a good idea, a bad idea?

• 1:36:14Dr. Mary Claire Haver?

  No, it'll come back.

• 1:36:15Dr. Vonda Wright?

  All these things we're talking about, it sounds like a lot of instructions and it is actually. But when you layer them on, it becomes your lifestyle.

• 1:36:24Dr. Mary Claire Haver?

  Yes.

• 1:36:25Dr. Vonda Wright?

  It's not a diet. It's not an exercise program. It's just how I live.

• 1:36:31Dr. Mary Claire Haver?

  Right.

• 1:36:31Steven Bartlett?

  Which brings me to my next question from the audience, which is what is the best diet for a woman who is perimenopausal?

• 1:36:38Dr Natalie Crawford?

  Plant forward.

• 1:36:39Dr. Mary Claire Haver?

  Plant heavy.

• 1:36:40Dr Natalie Crawford?

  Yeah.

• 1:36:41Dr. Mary Claire Haver?

  Yeah, because you're getting, you're getting, so when I'm talking to patients, we talk about the quality of their nutrition. So is your, is your pattern of eating, I hate to call it diet because it's a four-letter word now, but is the pattern that you're eating pro-inflammatory or anti-inflammatory?

• 1:36:57Steven Bartlett?

  What's pro-inflammatory?

• 1:36:58Dr. Mary Claire Haver?

  So meaning the things that you put in your body, are they likely to cause inflammation? And we know there are certain things that do that, like heavily ultra-processed foods, you know, in large amounts. Everybody can tolerate a little bit of everything. But if the majority of your diet, and for most Americans, the majority of their diet is 60% is ultra-processed foods, okay? Those are by and large pro-inflammatory.

• 1:37:20Steven Bartlett?

  What about red meat?

• 1:37:22Dr. Mary Claire Haver?

  Red meat in moderation and especially leaner ones seems to be a, a very reliable source of protein. As far as inflammation goes, it seems to be neutral in small amounts. Like heavily, like high-fat meats or processed meats, then you're flipping over into pro-inflammatory.

• 1:37:37Steven Bartlett?

  Is there a diet for fertility?

• 1:37:39Dr. Mary Claire Haver?

  It's very much what we're saying right here, that.

• 1:37:42Dr Natalie Crawford?

  Plants have fiber that's going to feed your gut microbiome that's going to decrease inflammation. So fruits and vegetables, getting enough fiber is the number one change that most people need to make. From there, we want to, of course, decrease all your ultra processed foods, healthy fats. Fat is the backbone of, like cholesterol is the backbone of your steroid hormones. So if you want to make hormones, we've got to have some cholesterol, some healthy fats coming in to provide the backbone for that. That's essential. So things like olive oil, nuts, your avocados, seeds, these are going to provide some of those healthier fats that are easier to use for you. And when it comes to protein, there's a lot of different protein sources. We know that the data is so hard on nutrition, because I can quote

• 1:38:23Dr Natalie Crawford?

  a study that says for every serving of plant protein that you take over animal protein, you have a higher chance of ovulating regularly. And that's true. A lot of that, though, is nuanced by the fact that people who eat plant-based sources of proteins tend to eat other plants in general, and less ultra-processed foods than people who have the highest quartile of meat intake. If we go to a micro level, though, not all meat, animal meat, is created equal. Animal meat does not have fiber in it. So we know it's not feeding our gut microbiome. So if we want to talk about carnivore diet, things like that is definitely not microbiome friendly for you and not hormonally healthy. So we really want to really have those whole foods, the fruits, vegetables, the healthy fats, the proteins that are going to be good

• 1:39:06Dr Natalie Crawford?

  sources. And just like we talked about other things, it's not all or nothing. Red meat every day is probably going to be inflammatory. Having it on the weekend is probably okay. And the way I describe this to patients is, let's imagine a scale where every decision you make can kind of tick up the inflammatory marker or bring it back down. If you are making active decisions that are more anti-inflammatory, you can tolerate the glass of champagne, the birthday cake, these little things that we know will cause inflammation in your body. But your body is meant to respond to inflammation and get back to normal. The problem is when it's constantly challenged, when 70% of the things that you eat cause this chronic inflammation

• 1:39:46Dr Natalie Crawford?

  inside of you, your body can no longer respond appropriately when it's challenged again.

• 1:39:52Dr. Mary Claire Haver?

  Things that are pro-inflammatory tend to also disrupt the gut microbiome. Tend to, like, it all makes sense when you think about it.

• 1:39:58Dr. Stacy Sims?

  And there's quite a few studies that are coming out in the four to five years before the one point in time called menopause. So in late perimenopause, that there's a significant decrease in gut microbiome diversity.

• 1:40:12Dr. Mary Claire Haver?

  Oh, Zoe, did that work?

• 1:40:14Dr. Stacy Sims?

  Yes.

• 1:40:14Dr. Mary Claire Haver?

  Yeah.

• 1:40:15Dr. Stacy Sims?

  And it's really interesting because of the second pass and the way that hormones are metabolized. When we have our natural cycle and we have an exposure of our sex hormones.

• 1:40:28Dr. Mary Claire Haver?

  Yeah.

• 1:40:29Dr. Stacy Sims?

  The common cycle, then we have more diversity because the gut bugs help unwind, I guess is the...

• 1:40:37Dr. Mary Claire Haver?

  So we metabolize estrogen into inactive metabolites. And then they get excreted in the feces. So it goes through the liver and then dumped into the bile and...

• 1:40:44Steven Bartlett?

  Does that mean that if I, if my gut microbiome is likely to be less diverse as I age, I need to be thinking more about...

• 1:40:50Dr. Stacy Sims?

  The diversity of your plant foods. And this is what's really...

• 1:40:53Steven Bartlett?

  Probiotics, probiotics, etc.

• 1:40:55Dr. Stacy Sims?

  Not over the counter.

• 1:40:56Steven Bartlett?

  Okay.

• 1:40:56Dr. Stacy Sims?

  We want to make food.

• 1:40:58Dr. Mary Claire Haver?

  You first start with food.

• 1:40:59Dr. Stacy Sims?

  Yeah.

• 1:40:59Dr. Mary Claire Haver?

  But not a pill that you're trying to take, but actually the food that you're putting into your body is the best nutrient for your gut microbiome is fiber.

• 1:41:07Steven Bartlett?

  What about protein? I wonder.

• 1:41:09Dr. Stacy Sims?

  The way I like to approach nutrition for people is first having people notice what they're eating.

• 1:41:15Dr. Vonda Wright?

  And then from that, break it down into, well, how much of it is protein? How much it is fat? How much is carbs? Without that kind of education, it's almost meaningless. So when we've done that and I'm making recommendations for protein, we will not build the muscle we need to build. We will not get stronger the way we're capable of getting stronger. A, if we're not eating enough, and B, if we're not taking enough protein. So the RDA recommendations of 0.8 grams per kilogram is survival doses of protein, like sitting on a chair like a mushroom.

• 1:41:54Dr. Mary Claire Haver?

  Preventing malnutrition is the goal of it.

• 1:41:56Dr. Vonda Wright?

  It's just survival. It is not for active people. It is not for living your best life people.

• 1:42:01Steven Bartlett?

  0.8.

• 1:42:02Dr. Mary Claire Haver?

  The recommended daily intake.

• 1:42:04Dr. Vonda Wright?

  Is 0.8 grams per kilogram.

• 1:42:07Dr. Mary Claire Haver?

  Of lean body mass.

• 1:42:08Dr. Vonda Wright?

  So it's low.

• 1:42:09Dr. Mary Claire Haver?

  It's very low.

• 1:42:10Dr. Vonda Wright?

  So the research supports, easily supports...

• 1:42:18Dr. Vonda Wright?

  Let's use pounds. .86 grams per pound for lifting people. I recommend over a gram, a gram for ideal pound. Because I'm presuming that the people I'm taking care of are going to start being active, that we're trying to build muscle, that we're not in starvation mode. So .8 grams per pound. I recommend one gram per ideal pound.

• 1:42:52Dr. Stacy Sims?

  So there's some other research that's come out looking at skinny fat. So that's normal weight obesity, so not as we're talking.

• 1:43:00Dr. Mary Claire Haver?

  Normal BMI.

• 1:43:01Dr. Stacy Sims?

  Normal BMI, but internal.

• 1:43:03Dr. Vonda Wright?

  High body fat.

• 1:43:05Dr. Mary Claire Haver?

  And then at the, and what happens is they have low muscle mass.

• 1:43:08Dr. Stacy Sims?

  Low muscle mass. So they took a group of women, split them up. So you had a control group and then you had this intervention group. And the only change they made, there's no exercise. And the only change they made was they brought the intervention group up to 1.6 grams of protein per kilogram.

• 1:43:26Dr. Vonda Wright?

  So that's .8.

• 1:43:27Dr. Stacy Sims?

  .8 per pound. And over the course of 12 weeks of eating that protein intake, this intervention group completely recomped their bodies. So their muscle quality came up, body fat went down. Control group, of course, nothing happened. So it just shows the importance of having that higher protein intake just to support basic muscle function.

• 1:43:49Dr. Mary Claire Haver?

  And the frailty data out of the WHO. So the Women's Health Initiative looked at multiple things, not just breast cancer and heart disease, but you know, they followed these women even off of HRT for decades. And when they looked at frailty scores in the elderly and protein intake above 1.6 grams per kilogram, had the lowest frailty scores just based on protein intake alone.

• 1:44:15Dr. Stacy Sims?

  Yep.

• 1:44:16Steven Bartlett?

  What about fasting? I know so many people that are doing water fasts and juice fasts and it's impossible.

• 1:44:22Dr. Mary Claire Haver?

  Have they told you why? I've had an evolution with the way I think about fasting. When I first kind of, you know, was stepping out of the box and what's happening in menopause and why was my body composition, I didn't know what to call it back then, but what was all this going on that was new? And all my patients were having it as well. And these were my girlfriends. I worked in a small town with a big university and these are PhDs and we're running marathons, we're doing all this stuff and everyone's kind of complaining at the same thing. And so fasting seemed to be helpful and my girlfriends were trying. We all kind of did this fasting thing and I was like super excited about it. Everybody felt better, blah, blah, blah, blah, blah. Okay. So fast forward, I'm learning more about hormones, body composition, protein intake, all of these needs. And suddenly, as I'm counseling my patients, I'm realizing I can't meet my own protein

• 1:45:07Dr. Mary Claire Haver?

  goals if I'm trying to fast at the same time. And I quickly realized if we're looking at health span, if we're looking at body composition, there may not be a lot of room for fasting for these patients, you know, or for my girlfriends, you know? And it is really difficult for my patients to reach their nutrition goals. So never at the expense of meeting your basic nutrition goals and your calorie needs. And it is really, really hard to do while fasting. So you may get a short-term benefit with weight loss, but there really doesn't now, Esther Sims can get into the nitty-gritty of, you know.

• 1:45:41Dr. Stacy Sims?

  But the basic idea of fasting, if we want to use the term fasting, we have to look at it as, are we talking about intermittent fasting or time-restricted eating? So intermittent fasting is kind of like, you know, you're water fast, you're five-day, two-day, all that kind of crazy stuff, which for the most part, men can get away with and have a positive impact on body composition, but women can't. If we want to talk about time-restricted eating and working with our circadian rhythm, which is optimal, then you have breakfast within or food within a half an hour of waking up that helps dampen that. Gerulin cortisol response I talked about before. So that everything's coming down, your hormones are starting to work properly. And your body's like, great, I'm ready to go. I can, I can handle this.

• 1:46:26Dr. Stacy Sims?

  And then you're eating at regular intervals. And I try to have people have protein and fiber at every eating interval. So that they are maximizing protein and fiber intake. Then you have dinner and then you don't eat after dinner.

• 1:46:38Steven Bartlett?

  Every eating interval?

• 1:46:39Dr. Stacy Sims?

  So breakfast, maybe you have a snack. If we're looking at training or exercise, if you're splitting your breakfast, then you're having some protein and carb before, you're having the rest of your protein or more protein afterwards. And then you're having some protein and some fiber at lunch. So you're having maybe tempeh or tofu or salmon with salad or fruit and veg. So every time you're eating, you have a protein and fiber focus.

• 1:47:06Steven Bartlett?

  So time restricted eating is within a 24 hour period?

• 1:47:10Dr. Stacy Sims?

  So you're looking at, I'm going to eat during the day when my body needs it.

• 1:47:13Steven Bartlett?

  Yeah.

• 1:47:14Dr. Stacy Sims?

  And I'm going to stop eating when I finish dinner. So I have about a two, maybe three hour break before I go to bed. So that when I go to bed, I'm not trying to digest food. My body can get into the parasympathetic responses it needs to, to sleep well for reparation.

• 1:47:27Steven Bartlett?

  And then I eat again at what time?

• 1:47:28Dr. Stacy Sims?

  When you wake up in the morning.

• 1:47:29Dr Natalie Crawford?

  It's typically about 12 hours of eating and 12 hours of not. So you're trying to follow that circadian rhythm and work with your hormones. It can also, when we do have that period of time, which maybe that sounds very intuitive, but a lot of people are eating at 10:00 PM, they're snacking on food and they're trying to go to bed. And then they're getting up. When you give your body a little bit longer, so at 12 hours time is when your body will really efficiently be using up all your glucose, really dropping some of those insulin levels. But it's not so much that it's stressful. And we're using stress very generically here, but on a cellular level, long periods of fasting for women specifically can be very stressful to the body. And that's why if you think about Stacy's example of what happened in two fasting periods

• 1:48:13Dr Natalie Crawford?

  to, you know, a man and a woman, different things are going to happen to your body if it thinks it's being in starvation. So we don't want to put your body in a starve state. We're just trying to give it a time period without food so that it can start to process the energy that's available differently.

• 1:48:29Steven Bartlett?

  Why, why not though? What's going to happen? I understand from what we talked about earlier that my fertility, my, my cycle's going to change. But is that it?

• 1:48:37Dr Natalie Crawford?

  Well, there's adaptive stress and then there's stress to the point of you're hurting yourself.

• 1:48:43Steven Bartlett?

  Men can, you said that men can do longer fasts.

• 1:48:46Dr Natalie Crawford?

  They can, they can do longer fasts and it can show to actually, you know, be something that might be advantageous for them for how their body is made, might increase their focus and some other metrics. But for women, these longer periods are actually going to promote more visceral fat storage and become pro-inflammatory. And you said it a little casually, but disrupting your hypothalamus and shutting off your hormone system will cause a low estrogen state and that's very problematic as we've talked about. So thinking about your body should not be in a starved state. So utilizing time restricted eating, meaning I'm going to eat within my circadian rhythm, the hours that there is sun outside, back what, how your body is made to function is working with your biology.

• 1:49:29Dr Natalie Crawford?

  If you're saying, I'm going to not eat for three days because I'm doing this fasting period, for women, that's going to induce a stressful state where you're going to start to store more as visceral fat and cause more inflammation.

• 1:49:43Dr. Stacy Sims?

  And if we bring it into the, you know, people holding a fast till noon or after, you're phase shifting. So it's like you're having social jet lag where if you're phase shifting your hormone responses, your appetite hormones, then you're not going to get into a good sleep because your body's like, it's not time to go to sleep. Your melatonin peak in women usually peaks around nine o'clock. So you start to get sleepy. That gets shifted to 11, 12. So you're not actually going to get good sleep because you now have reset your melatonin responses. So we want women to understand that time restricted eating, when you're not eating in the dark is really beneficial.

• 1:50:22Dr Natalie Crawford?

  Easiest way to say it.

• 1:50:23Dr. Stacy Sims?

  Easiest way to say it, yeah. You're fueling for your body during the day because that's when it needs the fuel. That's when we want to be able to create an environment that's supportive to hormone health, supportive to muscle growth, to brain health, to all the things and reducing stress when we can control that stress. So when you start phase shifting and holding fast and creating this stress on a circadian level, knowing that there's a circadian response on every cell as well as a total body circadian rhythm, that if you shift that, then we start seeing a lot of metabolic dysfunction, poor sleep and. Unfortunately, we see this in shift workers because that's what's happening. They're having circadian shift.

• 1:51:06Steven Bartlett?

  And they have significantly lower longevity. They live, what, I think I had 14 years less. If you're working night shifts.

• 1:51:14Dr. Stacy Sims?

  I don't know.

• 1:51:14Dr Natalie Crawford?

  You have higher rates of infertility, higher rates of pregnancy loss. You're more metabolically unhealthy. Of course, we're generalizing a group of people. And sometimes, I think we've all had moments of life where shift work was part of what we had to do. But night shift work, most people are not getting enough sleep during the day. And they're what we call flipping back and forth, right? Because you want to be on a daytime schedule on your off days and live your life. That you're constantly sacrificing what your body needs. And what I tell people is you may, if you can get off of that, it will be a healthier life pattern. But in moments where it's not, you need to really prioritize trying to get enough sleep, making sure that you're taking care of yourself in the other time periods.

• 1:52:00Dr Natalie Crawford?

  Because you're set up for a place that is going to cause hormone dysfunction and impact your metabolic health.

• 1:52:06Steven Bartlett?

  You believe the same, I believe.

• 1:52:08Dr. Stacy Sims?

  I advocate feeding ourselves for optimum health. To be any kind of active, you must feed yourself. And stop eating three times, three hours before bed.

• 1:52:22Steven Bartlett?

  So what do you think of people that do these longer fasts? Do you think that they've just been given poor advice? Because I know, I was talking about Mel earlier, and I know she does frequently does three day fasts. Because I think people think they've heard this term.

• 1:52:37Dr Natalie Crawford?

  Autophagy.

• 1:52:37Steven Bartlett?

  Autophagy is the term.

• 1:52:38Dr Natalie Crawford?

  Take it, Stacy.

• 1:52:39Dr. Stacy Sims?

  So this is the thing with autophagy. You get that with exercise. So the idea of autophagy is recycling the, some of the parts of cells that have broken down or somehow become dysfunctional. So your body's really good at cleaning that out. We see with exercise, it invokes that autophagy. With fasting, it invokes that too, but not the severe fasting, like three day fast, that kind of stuff. When we're looking at the telomere changes that people say with fasting, you get that with exercise. So telomere is points that we look on the DNA to see how. You're aging, so we want longer telomere length because that means you are more stress resilient. You get that with exercise because exercise is a big stress.

• 1:53:21Dr. Stacy Sims?

  It creates a change within, like we were talking about before. Yeah, adaptive stress, epigenetic changes, which improves all of those markers that people are so adamant fasting does.

• 1:53:33Steven Bartlett?

  What about fasting and then doing exercise? So fasted exercise, is that?

• 1:53:38Dr. Stacy Sims?

  For women, no.

• 1:53:41Steven Bartlett?

  That's what you taught me.

• 1:53:42Dr. Stacy Sims?

  For men, I'm going to say no as well because when we're looking at the fueling mechanics of exercise, muscle is a very metabolically active tissue. If your body is trying to fuel itself, it's going to break down the very first thing that's creating energetic need, which is muscle. We see in women, women-

• 1:54:05Steven Bartlett?

  So you're going to lose muscle?

• 1:54:06Dr. Stacy Sims?

  Mm-hmm. You're going to break it down and use the amino acids as fuel. You can tap into blood glucose and some fat, but when you aren't bringing blood glucose up through eating first, it's really hard for your body to understand that this is what you want it to do. So it's like, okay, I need to conserve fat. I don't want to go through all the glucose that I have because I need it for brain health. So I'm going to start feeding more amino acids in to fuel what I'm doing. For women, we already use more amino acid than men. So if we're looking at fasted training, then we're already increasing the amount of lean mass that our body's going to break down to use as fuel.

• 1:54:46Steven Bartlett?

  I'm pretty sure it was you that told me there's this part of the brain that's kind of checking if there's energy in our blood, if there's glucose in our blood.

• 1:54:53Dr. Stacy Sims?

  That's part of our hypothalamus.

• 1:54:55Steven Bartlett?

  And so the hypothalamus is this sensor that's kind of checking. And in a woman, again, correct me when I butcher this, but if it understands that there's no glucose in the blood, then it's going to go into that survival state, which is going to start to shut things down, which means growth of muscle isn't going to be possible. Because once upon a time, I guess that stress without the fuel would have been a threat, especially in the context of like my menstrual cycle and my reproductive health.

• 1:55:22Dr. Stacy Sims?

  That's a good way of wrapping it up. Yeah, it's not that we don't have blood glucose. It's low blood glucose and no nutrients coming in that the hypothalamus is sensing. So we're looking at neuropeptide responses within the brain, within the hypothalamus that controls appetite hormone, the way that your body's using fuel. So if we don't have stuff coming in, the hypothalamus is like, oh, wait a second, what's going on?

• 1:55:47Steven Bartlett?

  Is it fair to say the woman's body is more, I was gonna say stubborn, but that's slightly negative, less flexible than a man's?

• 1:55:54Dr. Mary Claire Haver?

  More complex.

• 1:55:55Dr. Stacy Sims?

  Complex.

• 1:55:56Dr. Mary Claire Haver?

  It's complex and more stress resilient.

• 1:55:58Steven Bartlett?

  To defend itself.

• 1:55:58Dr. Mary Claire Haver?

  It's very much stress resilient. So it's very defendable.

• 1:56:02Dr Natalie Crawford?

  It's trying to protect you. It really is looking at how, what is it going to do to keep your functions happening?

• 1:56:09Steven Bartlett?

  Balance.

• 1:56:09Dr Natalie Crawford?

  Balance. But because women can get pregnant and pregnancy is not a health neutral state, it's a huge strain on the body. That is an extra layer of one of the things that sometimes decides, I'm gonna put this to the side because I'm gonna

• 1:56:22Dr. Mary Claire Haver?

  To protect.

• 1:56:23Dr Natalie Crawford?

  Keep you functioning. I want to work on all of our other body functions. We're gonna shut off that side that's not sending out FSH and LH and making reproductive hormones.

• 1:56:33Dr. Stacy Sims?

  Because if we can't afford to keep you healthy, then we definitely can't afford to grow a baby and keep you healthy.

• 1:56:39Dr. Mary Claire Haver?

  If you are pregnant and go through times of severe stress, illness, injury, your body will eject what is in the womb through a miscarriage or, you know, early pregnancy loss or preterm labor, because it is always gonna try to protect you first.

• 1:57:00Steven Bartlett?

  So you're at a higher risk of a failed pregnancy.

• 1:57:04Dr. Vonda Wright?

  I wonder if I could frame Mel's, your question about Mel and the way I, I frame all the advice, whether it's research advice or internet advice is you have to know what your goal is. What is Mel's goal or your goal? Or because, listen, they're exclusive. Longevity, if longevity is your goal, like live longer at any cost, well, then there's a lot of research about severe calorie restriction and lifestyle and just lots of severe ways to live.

• 1:57:38Dr. Vonda Wright?

  Okay, if that's longevity is your goal, that's your goal. If your goal is peak performance like a pro athlete, that is a different kind of life and training and reps. And peak performance at the pro level doesn't necessarily get you longevity. Pro athletes live less, at least contact athletes live less than people focus on longevity. But the third bucket that most of us live in is health span and wellness.

• 1:58:04Dr Natalie Crawford?

  Yep.

• 1:58:05Dr. Vonda Wright?

  It's neither high performance, live less time. And it's neither austerity, live the longest possible. It is the middle ground. It's the homeostasis balance. And so when questions like that come up, the first question is my mind is which bucket are you in? Are you in a peak performance? You're going to do different kind of training, different kind of eating. We know you may have a decreased lifespan because of the stress you put on versus this. So what are we working for?

• 1:58:35Steven Bartlett?

  I think a lot of the people that talk about these fasts often say to me, especially when they're referring to juice fasts, that it's kind of like cleaning out the system.

• 1:58:42Dr Natalie Crawford?

  You have a liver.

• 1:58:43Steven Bartlett?

  They say it's like, it's like cleaning out.

• 1:58:45Dr Natalie Crawford?

  You don't need to clean out. That's not how you clean out your system. Taking the fiber out of those fruits and vegetables. Taking away all the things that you need.

• 1:58:54Dr. Vonda Wright?

  Juice is 500 calories of pure glucose.

• 1:58:56Dr Natalie Crawford?

  Yeah.

• 1:58:57Steven Bartlett?

  What if it's vegetable juicing?

• 1:59:00Dr. Vonda Wright?

  Why not just eat the vegetables and get the fiber for your guts?

• 1:59:04Dr Natalie Crawford?

  But you have a liver, your liver is. I think it's marketing.

• 1:59:06Dr. Vonda Wright?

  That's a marketing.

• 1:59:07Dr Natalie Crawford?

  I think they're falling prey to marketing.

• 1:59:08Dr. Vonda Wright?

  Tell me what that means.

• 1:59:09Dr Natalie Crawford?

  And that's a big wellness trend.

• 1:59:10Steven Bartlett?

  I know, but it's massive, honestly. You, yeah, I know so many people, so many of my best friends.

• 1:59:14Dr Natalie Crawford?

  Going on detox wellness retreats?

• 1:59:16Steven Bartlett?

  Well, even when I ask them why they're doing a water fast, they say, I'm just detoxing. Or when I ask them why they're grinding up this fruit and vegetable and as you say, pulling out all the fiber from it.

• 1:59:24Dr Natalie Crawford?

  It feels more attainable to say, I'm doing this crazy thing for three days, then I'm going to make a life switch to just live a more preventive anti-inflammatory lifestyle.

• 1:59:35Steven Bartlett?

  Before the Diary of a CEO was what it is today, it was just an idea. And it started with me, a cheap plug-in microphone and my Mac right here. And I have to say, when I first had the idea for the Diary of a CEO, my thinking was that the world might want to see into the diaries of some of the most interesting, successful people, really in high places that were doing interesting things. So after recording that first episode under my duvet, I sat on my Mac by our sponsor, Apple, and spent hours editing on GarageBand and eventually uploaded it. And honestly, I thought that would probably be it. But a couple of my friends said they enjoyed it, so I kept on recording. And over time, the microphone has changed and we now have this incredible setup here. But the thing that has stayed the same is I'm still using the Mac.

• 2:00:19Steven Bartlett?

  Even today, my entire team across our studio still uses the Mac. Our first few episodes maybe had tens of people listening, but now tens of millions of people tune in all over the world, which is still absolutely crazy to me. So if there is an idea that keeps tapping you on the shoulder, this is your sign to start. Your great ideas start on Mac. And you can find out more at apple.com/mac. Have you ever heard about this before? This thing I'm holding in my hands now? This is called Ketone IQ. Their website is ketone.com. You've heard me on this podcast talking about the fact that I stay much of the year in a ketogenic state, which is a highly restricted diet. And the reason I do that is plentyfold. One of them is I spend hours and hours talking to people for a living. So I want to make sure my brain is firing in an optimal way.

• 2:01:04Steven Bartlett?

  And the other reason that I do the ketogenic diet is because I just feel better. So when I discovered this, which is what they call an exogenous ketone product, where you can drink it and it increases your blood's ketone levels, I was blown away. I contacted them, I met them, I invested extremely heavily into their company. And I've become a co-owner of the company accordingly, and they sponsor this show now. So if you want to try this out for yourself, I recommend you try it. Just visit ketone.com/steven and you'll get 30% off your first subscription order. You'll also get a free gift with your second shipment. That's ketone.com/steven.

• 2:01:42Steven Bartlett?

  And in terms of supplements generally, do you know, again, not to bring Mel into this for the thousandth time today, but a couple of, um, couple of Christmases ago, I told her that she should be having creatine because I, all these people on my podcast told me it. And she said, no, it's for bodybuilders.

• 2:01:56Dr. Stacy Sims?

  Yeah, that's the old school thought. When we're thinking about creatine and how it got its chops in the supplement world, we're looking at muscle performance and taking five grams four times a day with some carbohydrate to enhance muscle performance is how it started. But when you start really disseminating down into the health aspects of creatine, creatine is used in every fast energetic of the body. So that means your brain, your heart, your gut, muscle, everything that requires energy from zero to 30 seconds, creatine is involved. Women have about 70, 80% of the stores of men. And when we start looking at all the different types of diets set out there, lots of exclusionary food diets, then the intake of creatine is lower. What we're finding in the research from health perspective is

• 2:02:41Dr. Stacy Sims?

  that it does so many positive things when you're able to saturate the tissues to bring it up with even a small dose of three to five grams a day. Our liver makes about three, but we don't necessarily eat enough to help supplement all of the tissues. How much would it take? Like 12 chicken breasts or something? 22. Okay. 22 chicken breasts. A lot. A lot. So when we look at the supplementation and being able to saturate all of our tissues thoroughly to support those fast energetics, we see things like better cognition, focus, we see a faster recovery from small brain traumatic, like a friend's daughter hit her head on the, um, the laundry door of the dryer and got a TBI or a small concussion

• 2:03:26Dr. Stacy Sims?

  from that, started using creatine, came out of it a lot faster. I mean, there are things that help with brain metabolism. We see women who have incidences with IBS or gut issues and they're using creatine. It helps decrease the symptomology. We're seeing now studies coming out about fatigue and this is where the 0.38 grams per kilogram of body weight or the equivalent of 20 grams if you're 60 kilos helps with fatigue and focus, especially if you're under a lot of high stress. Cause if you're under a lot of high stress, your body's going through a lot of blood glucose, trying to keep up with that stress. So creatine isn't just the bodybuilding set. There's so many different health benefits and it keeps coming out with more and more research to show how beneficial creatine is.

• 2:04:10Steven Bartlett?

  Could you give me the menopause supplement stack? If there is such a.

• 2:04:14Dr. Mary Claire Haver?

  Okay, so in general, we're not going to cure menopause with supplements. Let me just take straight up, okay? Most women are going to be deficient in fiber and most women are going to be deficient in vitamin D. And vitamin D is hugely important in multiple enzymatic processes in our body. And it's really hard to get enough through our nutrition, even eating stacks of salmon a day, which is really high in vitamin D. So about 80% of my patients are not only just low in vitamin D, they're deficient. So that is one that we can supplement safely up to about 4,000 IUs. International units is how vitamin D is measured a day without worries of becoming toxic or having too much vitamin D, which is possible. And so usually I'm having creatine, absolutely.

• 2:04:59Dr. Mary Claire Haver?

  It's like a go to. And we're looking at her nutritional profile. We're looking at her fiber intake and then we're adding in a fiber supplement if she needs it.

• 2:05:07Steven Bartlett?

  Natalie, in terms of fertility, what is the fertility supplement stack, I see?

• 2:05:11Dr Natalie Crawford?

  First and foremost, we're going to say that if you are trying to get pregnant, which by asking fertility, we're going to presume, we want to make sure you have folic acid onboard. So folic acid is the essential component, one very important part in cell division, but it's essential for a baby when it comes to brain development and spinal cord development. We call these neural tube defects. And the reason why I'm bringing it up is that there's a lot of chatter about folic acid out there. But it is the only supplement, folic acid in its folic acid form, that has proven to prevent these neural tube defects, such as your baby being born without a brain. And interestingly, in today's world, a lot of foods are also fortified with folic acid. But these are some foods that are often processed and people are consuming less.

• 2:05:55Dr Natalie Crawford?

  So we are having less consumption of folic acid in our diet, therefore making it even more important that we are supplementing with folic acid. As Dr. Haver said, vitamin D, vitamin D is essential for your entire body. But when it comes to hormone metabolism and fertility as well, we even see women who are going through IVF with donor eggs, and we know they're very good quality, have lower success rates if they have lower vitamin D levels. This is something that almost everybody is deficient in. We do tests and then target treatment to try to get you to an optimal level. But also omega-3 fatty acids are really important in your entire body, but especially in your reproductive years, if you might get pregnant. And I often recommend magnesium for most patients as well. And then from a fertility standpoint, if you have infertility,

• 2:06:39Dr Natalie Crawford?

  there are studies that show that coenzyme Q10 can be highly beneficial when it comes to egg quality. This is important in our mitochondrial health. And for the sake of the one question you asked, remember when we talked about eggs? We've got our genetic health, which is largely dependent on age. We have our metabolic health. The mitochondria from the egg controls all development for the embryo. And in fact, the cellular functions for an embryo, the first three days of life, solely come from the egg. The male genome doesn't even kick in until day three of embryo life. So the function of the egg to be able to divide and do normal cell functions is very important. And sometimes we see that reduced in infertility patients. And coenzyme Q10 is an easy thing we can get over the counter.

• 2:07:22Dr Natalie Crawford?

  Doesn't appear to have any harmful side effects and has potential benefits in some subsets. So my infertility patients, I add that on.

• 2:07:31Steven Bartlett?

  Guter. All things aging, performance, strength, bone. What is the supplement stack for longevity?

• 2:07:40Dr. Vonda Wright?

  Vitamin D. Magnesium is critically important for a variety of metabolic functions. Omega three for anti-inflammation. Creatine, I'm a big fan of. If we move looking at senescent cell load and inflammation, we haven't really talked about longevity, but senescent cells are those cells left over from normal function that are so damaged that they can't flip into programmed cell death. So they circulate around and produce noxious chemicals that can lead to a variety of disease. So we want to minimize those. And one way to do it is lifestyle. Another way is to use an herb called phytin. So I add that on.

• 2:08:23Dr. Vonda Wright?

  And then also I do myself and check levels on my people of intracellular NAD plus. NAD is a coenzyme in 300 metabolic reactions. It's an energetic pathway. Now, It's very popular right now and the critical differentiator for me is that taking whole molecule NAD such as in IVs, our body needs to make it. So for myself and for my people, I supplement with NMM, which is the immediate precursor of NAD plus so that my body can then turn it into NAD plus

• 2:09:06Dr. Vonda Wright?

  and it can work intracellularly. It can also be delivered two reactions out in the form of NR. These are in the B vitamin categories. So that in two reactions, your body makes NAD plus. So

• 2:09:22Dr. Vonda Wright?

  the data does not show that you can IV NAD plus for efficacy because it works intracellularly. So you supplement its precursor.

• 2:09:31Steven Bartlett?

  I've heard so many people talking about NMM recently.

• 2:09:34Dr. Vonda Wright?

  Yes, that's right. That's what I'm talking about.

• 2:09:36Steven Bartlett?

  Is there clinical evidence to show that it's effective?

• 2:09:40Dr. Vonda Wright?

  So you know, the lab that I work with, I happen to know the scientist and he has hundreds of thousands of data points checking before NAD plus levels intracellularly supplementing and then after, and he can elevate those levels.

• 2:09:55Steven Bartlett?

  And it's associated with longevity, like intrinsically associated with longevity. A lot of the the neuroscience, I guess.

• 2:10:01Dr. Vonda Wright?

  Well, it's it's intrinsically related to lots of normal metabolic function and energy in the body. Whether or not it makes you live longer, I don't have that data.

• 2:10:13Steven Bartlett?

  Is it a tablet?

• 2:10:15Dr. Vonda Wright?

  It is a powder, the way I take it.

• 2:10:18Steven Bartlett?

  What about collagen? People talk a lot about collagen. It's in all the protein powders now.

• 2:10:22Dr. Stacy Sims?

  I know, but it's not a protein as we think about it. Like you'll see all these collagen protein. It doesn't count as dietary protein for muscle development.

• 2:10:30Steven Bartlett?

  Does it work as a supplement?

• 2:10:32Dr. Stacy Sims?

  There. Depends on what you're looking for. Yeah, exactly. And Mike Ornsby out of University of Southern Florida, he has been doing quite a bit of research on collagen and joint pain and found that there is some efficacy in taking the type 2 collagen to reduce joint pain. It doesn't help with cartilage regeneration. It doesn't help with osteoarthritis, but it does dampen inflammation and joint pain.

• 2:10:57Dr Natalie Crawford?

  So again, it depends on what you want to use it for.

• 2:11:00Steven Bartlett?

  In the first episode, we talked a little bit about environmental toxins. And I wanted to, before we talk about sleep and close off, I wanted to just mention environmental toxins and the role they play. The term microplastics has been very, very popular of late. When we talk about environmental toxins, are we talking about microplastics in the air? And maybe the water, what do we mean?

• 2:11:19Dr Natalie Crawford?

  Essentially, it's anything in our world that is impacting your body and how it functions. There's a few different types, right? So we have endocrine disrupting chemicals. These are actual toxins in the environment, in Cosmetics. Cosmetics, our kitchen, our food, that change how our endocrine system works, our hormones. There's also things like microplastics, like you mentioned, which are actually going to deposit in our body and can cause fibrosis even in our ovaries. Therefore, changing how an organ's able to respond, even if it is given normal hormone signals. And then I also lump into this category behavioral toxins, right? Things like alcohol, marijuana, cigarettes, the, the choices that are toxic in our world as well. So that toxins is kind of a large category.

• 2:12:03Dr Natalie Crawford?

  There are some toxins you can control. You can try to filter your water. You can learn what is in your water so that you can say at the, you know, EWG, this is my zip code. This is what's in my tap water. What type of filter might I need to try to have healthier drinking water in my home? You can change what you're cooking with, not using nonstick cookware or Teflon. You can get rid of plastics and especially what you're putting hot foods and beverages in because the heat is allowing those toxins to leak into those things. And then, as Dr. Haber said, our cosmetics, things that you use every single day that you put in and on your body. Yeah, are things that you're having a higher exposure to. And it's really important to decrease those because things like air quality, you might not have as much control over based on where you live.

• 2:12:49Dr Natalie Crawford?

  And there's so many toxins in our world in general that it's unrealistic to say, let's avoid all of them. And because of this, we have that same mentality that we see with exercise sometimes. Well, it's just, there's too many. I can't avoid them all. So I will ignore this category because it's easier to just do nothing. Instead of making active decisions to start to live a less toxic life.

• 2:13:11Steven Bartlett?

  What changes have you made to? Remove pollutants and environmental toxins from your lives. Cause we're in that fertility journey, I remember I came in one day and like all my shampoo and stuff had gone.

• 2:13:21Dr Natalie Crawford?

  Yeah, so you're

• 2:13:22Steven Bartlett?

  My nice stuff is

• 2:13:23Dr Natalie Crawford?

  Starting to look through your products and getting rid of things that have endocrine disruptors in them. You wanna look, the kitchen is probably the greatest source of exposure for most people. So there's really no need to have any plastics in your kitchen, so getting rid of them. But many people don't think about, when you do have processed foods, the wrapping, the container, anything that's coming packaged, likely has toxins in it. When you order a DoorDash and it comes and you have it in a container, that's often hot food in a container that is leaching chemicals into it. So a simple thing is, take it out of that right away, even if you're not eating it. Put it into something glass or a different type of container. So you can try to minimize that exposure. Thinking about hot beverages, things that go in the microwave or the dishwasher especially.

• 2:14:06Dr Natalie Crawford?

  But then other things like thermal receipts, so getting receipts, thermal receipts have BPA in them. So getting receipts or

• 2:14:13Steven Bartlett?

  Thermal receipts.

• 2:14:13Dr Natalie Crawford?

  Yeah, so the airline tickets or that thermal paper. So just the receipt from the grocery store when they say, Stephen, do you want your receipt? You can just say, no. Thank you. And then if you work with thermal paper, maybe you're a cashier and you touch it over and over. I highly recommend you wear gloves because your exposure to that thermal paper is so much higher that it can become problematic for you.

• 2:14:33Steven Bartlett?

  Does it really make a difference if I take the receipt or not?

• 2:14:36Dr Natalie Crawford?

  You know, there's a lot of things where you can do, they will say, that person touched receipts all day and they still got pregnant or their sperm was great or they lived a long time. We can list a whole lot of negative behaviors or habits or exposures that one person might tolerate just fine. And for somebody else, the sum of all of these behaviors add up to be something that puts them in a place that is very pro-inflammatory, not healthy for the now or for the future. That to me is an easy, on the scale of decisions that are hard or that are easy, trying to change the things that you're exposed to in your world, you have to spend some time to learn about it. You might have to buy some new things.

• 2:15:16Dr Natalie Crawford?

  But over time, those decisions are ultimately easier than how you eat, your exercise, those take longer commitment.

• 2:15:24Dr Natalie Crawford?

  And especially if you're partnered, if you live with somebody, then the foods that you eat, your sleeping habits depend on them. You both have to be together on this. So sometimes I always say toxins are to one place, a thing you can do. You can look at your products. You can start to, when they run out, say, is this one healthy for me? Should I get something that's going to have less of an impact? That one time of using very scented hand wash is no big deal. But when you wash your hands with that highly scented hand wash, five times a day, over and over, it is just an avenue of endocrine disruption that can add up to the litany of the other ones that you're experiencing. So we're all saying, these little changes,

• 2:16:07Dr Natalie Crawford?

  on one hand, singularly probably do not matter much, but together, they do.

• 2:16:12Steven Bartlett?

  And there's a link between environmental toxins in menopause, or early menopause.

• 2:16:17Dr. Mary Claire Haver?

  Early menopause, we think so. So, you know, you were born with a shelf life, a genetically predispositioned shelf life on the ovary. Okay, and we don't know a lot of things to extend that shelf life, because we have a certain number of eggs. But there are a lot of things we can do to speed that process up. So that's going to be smoking. Women who smoke cigarettes, or, you know, even, we're looking at vaping now because it's a newer thing, but definitely tobacco consumption, you know, in the form of smoking, we see earlier menopause. The stress, so there was this incredible study where they looked at women who were sexually abused, who then had children who were sexually abused, went through menopause, I think, nine years sooner.

• 2:17:02Dr. Mary Claire Haver?

  So, and it's the only study that looked at this, and it happened to be the stress they looked at was sexual abuse in the mother and the child. And so, they went through menopause nine years sooner. So there is a component of emotional stress, and long-term chronic emotional stress.

• 2:17:17Dr Natalie Crawford?

  Because it does cause chronic inflammation. And the ovaries are highly sensitive to chronic inflammation. We know that BPA exposure has shown that if you have a higher level of BPA exposure, you have lower ovarian reserve, meaning less eggs in your ovary will go into menopause earlier.

• 2:17:33Steven Bartlett?

  What is BPA?

• 2:17:34Dr Natalie Crawford?

  BPA is one of those environmental chemicals that we're exposed to largely through plastics, but it's also one that's in the thermal receipt paper that we're trying to avoid our exposure to. And that's where some of the data, even when it comes back to food, where soy, in taking soy products can actually be very protective because it combats BPA. So how it works. So when people say, oh, you shouldn't have tofu, you're a man, soy is so bad for you. That's actually false. And we found that people who had a greater exposure to soy products actually had the lowest level of BPA and improved reproductive performance because of that. So there's definitely correlation with these toxins in our world. And we might say, oh, is it linked to menopause?

• 2:18:17Dr Natalie Crawford?

  Maybe nobody's done that exact study, but it absolutely is if you have lower eggs at an earlier time period.

• 2:18:23Dr. Mary Claire Haver?

  That's going to give you an earlier menopause.

• 2:18:24Dr Natalie Crawford?

  You would go into menopause early.

• 2:18:25Dr. Mary Claire Haver?

  You know, the flip side of fertility is menopause.

• 2:18:28Dr Natalie Crawford?

  Right.

• 2:18:29Steven Bartlett?

  And lastly, I wanted to talk about sleep.

• 2:18:32Dr Natalie Crawford?

  Well, it's all of our favorites.

• 2:18:33Dr. Mary Claire Haver?

  Yeah.

• 2:18:33Dr Natalie Crawford?

  And we're doing it well.

• 2:18:34Steven Bartlett?

  Oh, yeah. I wonder, I've heard you refer to sleep as the pillar of everything.

• 2:18:40Dr. Vonda Wright?

  And I say that because we think sleep is just passing out, like we're not conscious. Well, that may be true from a, from a, our viewpoint, but it is the most regenerative period in our day. Actually, the brain is processing information, getting rid of toxins. The body is able to settle and again, get rid of toxins. But many women in midlife have completely disrupted sleep because estrogen is critical.

• 2:19:07Dr. Mary Claire Haver?

  Most.

• 2:19:08Dr. Vonda Wright?

  Yes, 80%, very high. Estrogen is critical for sleep patterns.

• 2:19:18Dr. Vonda Wright?

  Many women wake up at 3:37 or thereabouts, either with a plummeting blood sugar or that seems to be around the time in the middle of the night that the sleep disruption has. So this broken up sleep, if you don't do it, then all the lifestyle things Stacy and the rest of us have been talking about are nearly impossible to do if you're under recovered. And so I have made. After nearly 11 years of not sleeping because of training and child, a religion almost. Like, I am dedicated to this function. I do not eat three hours before I go to sleep. It's one of the primary reasons that I made the decision to stop drinking alcohol, because that completely disrupted my sleep.

• 2:20:03Dr. Vonda Wright?

  And I am more conscious of circadian rhythm than I've ever been in my life, meaning I go to bed when I'm, except, except probably when I'm traveling, but at the exact same time every night. But more importantly, get up at the exact same time every day to start my circadian day. And to start my adenosine usage so that by 9:30 at night, I'm ready to rest. It's that important.

• 2:20:32Steven Bartlett?

  A Woman's Guide to Aging with Power Unbreakable.

• 2:20:35Dr. Vonda Wright?

  Yes, Unbreakable.

• 2:20:36Steven Bartlett?

  And central to that is circadian rhythms and sleep, right?

• 2:20:40Dr Natalie Crawford?

  Yeah.

• 2:20:41Dr. Vonda Wright?

  It is, because the premise of this book is that women are already winning the longevity race, but we suffer longer. And we have this vision of women aging, which is usually a vision of frailty. But through the mindset changes, through the behavior such as sleep and lifting and considering hormones, we can age in a different way. So I'm trying to re-educate the world that a woman's destiny is not frailty. A woman can age powerfully, but not if we sit around and wait for time to make us its victim. We must be proactive. And sleep is one component of that.

• 2:21:25Dr Natalie Crawford?

  This should be the very first thing you do. Sleep sets the stage for your entire day. It's really that foundation of your health. If you are going to start the day in a sleep deficit, you're starting out stressed, inflamed, insulin resistant. There's going to be no behaviors you can do during the day that are going to overcome the deficit. And we know that Women who get less sleep, they take longer to get pregnant. They have higher rates of infertility. We know that men who get less sleep have lower sperm parameters and lower testosterone levels. So if we are saying, you, Stephen, you know, what's one thing you might be able to do? Well, are you sleeping well? That's one of the first things you can start to do to say, am I getting seven to nine hours of good quality sleep? That's not just time in bed because Mary Claire has her phone on her.

• 2:22:10Dr Natalie Crawford?

  That is actual sleeping time. And that makes a huge difference in trying to achieve, you know, a hormonal health, which is really what we're all saying here is how do we get our body in the best quote unquote balance that we can, which means working with the different building blocks of our body in the most optimal way for as long as possible to be healthy.

• 2:22:32Dr. Stacy Sims?

  And even if we're not looking from a fertility standpoint, you can't invoke any kind of metabolic or body composition change without adequate sleep. So that's what I mean is like when we're talking about the pillars and sleep being one of the first things we have to work on, you can't invoke any kind of change with.

• 2:22:49Dr. Mary Claire Haver?

  We're not talking about ambient induced sleep.

• 2:22:50Dr Natalie Crawford?

  No, no, no. Medication induced sleep doesn't count.

• 2:22:52Dr. Mary Claire Haver?

  This is not medication induced sleep. There is a huge percentage of patients out there who are addicted to these medications and it has become the only way that they can sleep.

• 2:23:01Steven Bartlett?

  I've been really shocked at several of the women in my life that are between the ages of, I'm going to say thirty five, yeah, thirty five and forty five, who have like three to four hours sleep and they appear to be perfectly fine.

• 2:23:15Dr. Mary Claire Haver?

  They are not.

• 2:23:15Dr Natalie Crawford?

  They are not. Their cells are not fine, Stephen.

• 2:23:17Dr. Mary Claire Haver?

  No.

• 2:23:18Steven Bartlett?

  Because obviously, because I do this a lot, I learned from all these scientists, but there's one particular, there's been this two particular women that I'm very close to that I actually work with in different capacities, who showed me their whoop data and would often tell me, they would say, I get three hours, four hours sleep. And I thought, there's no way, because she did a five K this morning at six AM. So there's no way she's getting through to four hours sleep. So put a sleep tracker on her and she was getting through to four hours sleep and her restorative sleep is like forty five minutes. But she's springing into the makeup chair next to me and she's all, she's got all the energy. I'm thinking, what the hell is going on?

• 2:23:50Dr Natalie Crawford?

  Youth.

• 2:23:51Steven Bartlett?

  But I'm younger than her.

• 2:23:52Dr. Mary Claire Haver?

  Yeah. I mean, but when I was in training, I was getting three to five hours and getting up and operating and functioning, but I cannot do that now.

• 2:23:59Dr. Stacy Sims?

  If I got three to four hours, I was good for the day.

• 2:24:02Steven Bartlett?

  How?

• 2:24:02Dr. Stacy Sims?

  Because I was twenty years, twenty five years younger.

• 2:24:07Dr. Stacy Sims?

  I think we all got through, I was telling some of my earlier phases.

• 2:24:11Dr. Mary Claire Haver?

  I mean, a breastfeeding mother is getting three to four hours.

• 2:24:14Dr. Stacy Sims?

  Yes.

• 2:24:14Dr. Mary Claire Haver?

  You know, that is part of the wow, we're built, we can function, but age will take that resilience away from us.

• 2:24:20Steven Bartlett?

  Because perimenopause causes sleep fluctuations as well that because of the change in hormones, right?

• 2:24:25Dr. Mary Claire Haver?

  Exactly.

• 2:24:26Steven Bartlett?

  And are women just assuming that's normal and rolling with it, or is it okay?

• 2:24:34Dr. Mary Claire Haver?

  I think we have more at public education about how important sleep is and the number of hours you need and the quality of the sleep. So I think years ago, that was there, normal, and I'm just gonna keep going. But now they're coming in saying, this is a problem.

• 2:24:47Dr. Stacy Sims?

  Yep.

• 2:24:47Dr. Mary Claire Haver?

  I need help.

• 2:24:48Dr. Stacy Sims?

  And I would be interested to see your glucose monitor when you first used it. Cause that's how we can kind of navigate sleep too, is showing hypoglycemic effects for women who are exercising in perimenopause and not eating enough.

• 2:25:04Steven Bartlett?

  Melatonin, is that a solution?

• 2:25:06Dr. Stacy Sims?

  No.

• 2:25:06Dr Natalie Crawford?

  It can be a tool in the toolkit. Most of the time, you know, most people are taking too high a dose of melatonin, which is actually doing more harm than good.

• 2:25:16Steven Bartlett?

  What harm is it doing?

• 2:25:17Dr Natalie Crawford?

  Well, it's actually shutting off part of the brain to be able to help control their circadian rhythm. And then they're completely dependent upon it. And it's such an artificial induction, it's gonna wear out of their system. So your melatonin is supposed to rise, help you go to sleep, and then it falls at a rate for when you're going to wake up. So that when it's lower, you're gonna wake up and your cortisol will naturally rise. Melatonin can be helpful in very low doses.

• 2:25:41Dr. Mary Claire Haver?

  Like point three, most people are taking five to 10.

• 2:25:44Dr. Stacy Sims?

  10, yeah.

• 2:25:45Dr Natalie Crawford?

  Yeah, so I often recommend, you know, the patients take maybe like a milligram, but you have to buy a children's melatonin very often for that dose of it. Because people are taking these huge, huge amounts over the counter, you can just get so much. And so what you wanna make sure is that if you're using it, you're going to take melatonin at a time where you're going to be able to go to sleep about 30 minutes afterward too. Because people are also using melatonin and then not allowing themselves the restful moment when it's trying to kick in. And then they're taking more, or they're staying up later, and they're suppressing their brain's ability to make their own melatonin.

• 2:26:19Steven Bartlett?

  One of the questions we had from the audience was from a young girl that said, a young woman that said, I'm 24 years old and I struggle so much to fall asleep. How can I fix my sleeping naturally if I have disturbed, set circadian rhythm? And especially during my menstruation, my sleeping pattern seems to get worse.

• 2:26:38Dr. Stacy Sims?

  This one would be interesting to see, like, what is her daily, like, what are her daily habits? If we can kind of bring calorie intake and all those things back into the day so she's not phase shifting, and then use things like L-theanine, which is a non-protein amino acid that works the GABA, right, trying to bring parasympathetic activation back and making

• 2:27:01Steven Bartlett?

  them down.

• 2:27:01Dr. Stacy Sims?

  Yeah, and seeing what are your sleep hygiene habits? Is your phone out of your room? Do you have like a cool bedroom? Do you have earplugs to block out some of the extraneous noises that might

• 2:27:13Dr Natalie Crawford?

  Partner doing?

• 2:27:14Dr. Stacy Sims?

  Yeah.

• 2:27:15Steven Bartlett?

  But sleep is really a lifestyle problem for most people, isn't it?

• 2:27:18Dr Natalie Crawford?

  But magnesium can be advantageous as well, especially if you're on your menstrual cycle and you're having menstrual-related sleep.

• 2:27:23Dr. Stacy Sims?

  Yes.

• 2:27:23Dr Natalie Crawford?

  So I think that's an important thing.

• 2:27:25Steven Bartlett?

  Why?

• 2:27:26Dr Natalie Crawford?

  Well, it's just, many women run low in magnesium, especially when your hormones are very low, especially when you're estrogen and progesterone low, you're having, you know, contractility of your uterus, when you're having menstrual cramps. Magnesium can help counter some of that and can also help you, if you're taking it at night, get into a more restful pattern.

• 2:27:45Dr. Mary Claire Haver?

  So I've been working with a sleep medicine specialist, and one of the things she points out, which I now discuss with my patients, is if we're, women wake up in menopause from hot flashes from night sweats, and then the relaxation we get from progesterone is gone, so we can add that back in. So say we've done all the things, we've given her a touch of melatonin, we've put her on hormones, she is still waking up at three in the morning consistently. She deserves a workup for sleep apnea, because women, disease differently than men, and men with sleep apnea, it's a very common presentation of snoring, they're waking up the partner, you know, all these things. Women are much quieter about it. They still have the palate that falls back and the relaxation, and that's hormonally driven for a lot of women.

• 2:28:30Dr. Mary Claire Haver?

  And so they're becoming hypoxic in the middle of the night from, you know, that's one of those side effects of having sleep apnea, is you stop breathing and you, your oxygen levels decline, you become hypoxic, but we are not recognizing it in women, more than 50% of women are going undiagnosed and are living shorter lives, having more Alzheimer's because of this. So if I have a patient coming in and we've done everything and she is still consistently getting up, I'm sending her for a sleep apnea evaluation.

• 2:28:57Dr. Stacy Sims?

  I've also been reading literature on CBT, so insomnia CBT, that they've done with a lot of veterans and shift workers. And that seems really interesting. To help them fall back asleep. Yeah, to break the pattern because your body and your brain learn that wake up pattern. So if you can reset it, then that's very helpful as well. Yeah.

• 2:29:18Steven Bartlett?

  What is the most important thing we should have talked about that we didn't talk about, Dr. Wright?

• 2:29:23Dr. Vonda Wright?

  I think we covered an amazing array of information. But what I want women to walk away from this is that there's a hope for feeling like themselves again. And that they are worth investigating to the ends of the earth to find the answers they need and not simply giving up the first time somebody says no to them or doesn't hear them when they say that they don't feel like themselves. They must continue to pursue it. And number three, that they are worth the work that it takes to age with power.

• 2:30:02Steven Bartlett?

  Beautifully said.

• 2:30:06Steven Bartlett?

  Octavia?

• 2:30:07Dr. Mary Claire Haver?

  You really do need to be the CEO of your own healthcare. We have a medical system that was not built to serve the aging woman. After reproduction ends, it's just we become small men with breast and uteruses, to quote Dr. Sims. And you, it's okay to educate yourself. It's okay to read the books. It's okay to go in educated with checklists. And you're going to probably have to do that. And to go find someone who's educated in the health of women after reproduction ends. And that could be your internist, it could be family medicine. But like, there's no, no one owns menopause when life after reproduction ends. You know, no specialty really owns it.

• 2:30:50Dr. Mary Claire Haver?

  And so you are going to have to quarterback this, a lot of it yourself, until you find the right partner in this care, but it is worth it.

• 2:30:58Steven Bartlett?

  Beautifully said as well.

• 2:30:59Dr Natalie Crawford?

  Yeah, I think when it comes to your health journey, nobody is really responsible for it except you. But there's this idea that we should wait until things are wrong to then go get them fixed. And what we are all trying to do across the spectrum of, you know, women's health and their lifespan is to say, many of these things, if we start focusing on them much earlier and take a preventive approach, which is often against some of these recommendations about when you should screen or when you should do testing. But if we say, well, what is best for you as an individual? Focus on setting up a life that is going to help prevent some of these diseased outcomes, start testing things earlier. You're going to be in a position of power to make the decisions that are right for you from a place of education

• 2:31:44Dr Natalie Crawford?

  and not be left making them out of fear or misinformation or not knowing. Because when it, women will go through these stages. Time will make your fertility decisions for you if you do not. That's a fact, that your ovaries will stop functioning. You will go into menopause. So we need to both prepare for our reproductive years, optimize our fertility the best we can, if that's a life goal for us, but to realize that it doesn't stop there, that you're, have to prepare for the next stage of the journey and what that's going to look like for you. But the steps to take care of yourself start well before, if you're able to.

• 2:32:18Dr. Stacy Sims?

  I look at the, the research and the health outcomes right now for women, and it is a very confusing space. So I always preface with the fact that I want women to be empowered. And how do you do that? You can't Google things and find out. So it's asking questions, it's sharing information. Most of all, taking up the space because you've earned it. I get so tired of the rhetoric that women should be small and demure and be like a delicate flower and things are happening to them that they can't control. I want the narrative to shift. I want people to say, I own this space. I'm taking up the space. And it's my, I don't like to use the word right because it invokes a lot of angst. But it is your ability to understand your own body

• 2:33:03Dr. Stacy Sims?

  and advocate for yourself that's going to allow you to take up that space. And get the answers that you want. I've been advocating for so many women, myself included, and the pushback that you get from the medical society is real. It's not that they necessarily are trying to gaslight you, but it's just a product of the system. So you do have to push those boundaries. You do have to ask those hard questions. You do have to go in prepared to have that pushback, but take that space because everybody deserves a place at the table. And women's healthcare is being shunted in a way right now that is really unacceptable and we need to have groundswell movement to push back.

• 2:33:44Steven Bartlett?

  Thank you all so much. Thank you.

• 2:33:46Dr. Stacy Sims?

  Thank you.

• 2:33:46Steven Bartlett?

  I really mean that. I'm thanking you on behalf of the many millions of people that are probably listening to this conversation. Because, you know, your conversations on this show have delivered more than thirty million downloads between you. So across YouTube and across audio. I was looking at the numbers and it's staggering and you think about the impact of reaching potentially thirty million people just on this show in long form. And then their friends and then their family and then the advice that they give to everybody they know. And that domino effect is causing this wonderful ripple across the planet. And it's turning the lights on in different households and within families and amongst business owners like myself. So that we can all cater to the plight, I guess, of women's health

• 2:34:28Steven Bartlett?

  in a more effective way. Because, you know, even as a man, I've learned, oh God, so much from you four.

• 2:34:34Dr. Stacy Sims?

  Great.

• 2:34:34Steven Bartlett?

  And the impact it's had on my life through improving how I show up for the women in my life, but also the way that I'm able to respond and support my partner, my sister, my mother in difficult times has been profound. And I think some, you know, and well done to all the men that have listened to this conversation and have gotten to this stage because I know you don't, you often don't think it's a problem that you're going to deal with, but when fifty one percent or fifty two percent of the planet are women is going to be a huge part of your life, whether as you having daughters or sisters or mothers. And through all of the work that you've done, I've been able to understand the women in my life better.

• 2:35:15Steven Bartlett?

  And actually, that's protected my relationships. And if it's protected my relationships, it's protecting me. And I've really noticed that I've noticed how I've changed, especially through understanding the menstrual cycle, how I treat my partner. But it's you four, you four are like the Avengers of what you do. You're the very best in your industries. And I highly recommend everybody goes and checks out. I'm going to link all of your books below. Unbreakable, the fertility formula, the new menopause. I believe you've got a new book on the way. New perimenopause. The new perimenopause. I'll link that as well if it's available for preorder and raw. But also just you all make content, have Instagram pages and have websites. So all of that will be linked in the description below. And if you want to go deeper on these

• 2:35:57Steven Bartlett?

  subjects that we've talked about today, then those are the doorways into a deeper understanding. I appreciate you all so, so much. Thank you. We've been recording for what, nine hours now? It was worth it. To other people. Love it. Thank you. Thank you.
