0:01 Speaker 00 Hi guys, this is Tony Robbins. You're listening to Habits and Hustle. Crush it.
0:07 Jen Cohen? Hey friends, you're listening to Fitness Friday on the Habits and Hustle Podcast, where myself and my friends share quick and very actionable advice for you becoming your healthiest self. So stay tuned and let me know how you leveled up.
0:30 Jen Cohen? Aren't these IVs really good for brain, like cognition and focus and?
0:35 Speaker 02 NR ones?
0:37 Jen Cohen? Yeah.
0:37 Speaker 02 Yeah.
0:38 Jen Cohen? And also for the mitochondrial?
0:40 Speaker 02 Yeah, as a matter of fact, my favorite stack for sleep deprivation is NR, NAD, or NMN, which are all just like NAD precursors and creatine. Because when you're sleep deprived, two things happen. You get less ATP in the brain and creatine, the phosphagen and creatine can help to replenish that. And then the NAD assists with the cellular repair mechanisms that should have occurred when you're sleep deprived. And so, yeah, I mean, coffee and energy drinks and all that stuff and kind of Band-Aid sleep deprivation.
1:05 Jen Cohen? Right.
1:06 Speaker 02 Using about 10, higher, higher than what you use for strength and power, like 10 to 20 grams of creatine a day. And that will give you disaster pants if you take it all at once. So you do like four or five gram portions spread throughout the day if you're sleep deprived. I wouldn't, you don't need to do this every day. And then NAD, IV, patch, oral.
1:22 Jen Cohen? Okay, wait, so that's a good, that's actually a good clip.
1:25 Speaker 02 Fantastic for sleep deprivation.
1:26 Jen Cohen? Okay, so say that one more time because I want to, I want to make sure people get that. So if you are sleep deprived, here is a cocktail that you should do that's very effective. Go ahead. Say it again. The NR.
1:39 Speaker 02 If, if you're sleep deprived, then coffee, five hour energy, green tea, like all these central nervous system stimulus can kind of like short term jack you up. But NAD combined with creatine, that stack is incredible because it helps to simulate a lot of what you would have gotten during sleep. ATP restoration in the brain and cellular repair mechanisms.
2:00 Jen Cohen? Okay, this is my question. Can you take NAD, if I just took like a TruNiagen supplement and a creatine, creatine scoop?
2:09 Speaker 02 Yeah.
2:09 Jen Cohen? That would work?
2:10 Speaker 02 Couple capsules, although I recommend more than you'd usually take. So you take like four capsules of like the TruNiagen and then you do 20 grams of the creatine, but you split that into four or five gram portions throughout the day.
2:21 Jen Cohen? Can't that bloat you to take that much creatine?
2:23 Speaker 02 Mm hmm. That's why you wouldn't want to do it every day. But you also shouldn't be sleep deprived every day.
2:27 Jen Cohen? That's true.
2:27 Speaker 02 Deeper issues to address.
2:29 Jen Cohen? Are you not wearing any trackers anymore because of all the EMFs?
2:33 Speaker 02 I wear this ring.
2:34 Jen Cohen? Oh, you do?
2:35 Speaker 02 Yeah. I wear a ring. Rings don't produce an appreciable amount of EMF.
2:38 Jen Cohen? Yeah.
2:38 Speaker 02 Like a class three Bluetooth signal is not a big, like, maybe if you had it next to your head, like AirPod inside your ear all the time. Some people say it affects red blood cell flow and can cause clumping or, you know, heating of tissue, but Bluetooth is way less important of a fish to fry compared to like Wi-Fi and radio frequencies from phones, et cetera. So I use a cheapo, actually just replaced it. My last one pooped out after six years, but I use a cheapo, like thirty dollar Timex watch and a ring. And a blood glucose monitor.
3:09 Jen Cohen? Oh, so you do wear the?
3:09 Speaker 02 I do wear a blood glucose monitor.
3:10 Jen Cohen? Why?
3:11 Speaker 02 Not because I don't know by this point, after using one for two years, what does and does not spike my blood glucose, but just because what gets measured gets managed. I'm less likely to like blow through a bunch of dark chocolate trail mix on an airplane if I know I gotta look at the levels later on.
3:26 Jen Cohen? I love that line, by the way.
3:27 Speaker 02 Or drink a one hundred calorie cane sugar infused caramel latte, high protein, nice coffee.
3:31 Jen Cohen? This one may be, let me, Clay's gonna hate me.
3:34 Speaker 02 With false advertising on the front of it.
3:36 Jen Cohen? Why?
3:36 Speaker 02 It says lactose free energy, but it's got skim milk in it. However, they added lactase enzymes. So lactase enzymes digest the skim milk.
3:43 Jen Cohen? Oh, my God, I'm gonna get, I'm gonna get fired. I'm just kidding.
3:46 Speaker 02 It's, it's not that bad of a, like, that's good that they put lactase in there along with the skim milk. I would rather, like,
3:53 Jen Cohen? Look at this one. Look at the French vanilla.
3:54 Speaker 02 Wave a magic wand, I'd rather they be using regular milk because all the studies on the benefits of dairy tend to be much stronger with full fat dairy compared to low fat or fat free dairy.
4:05 Jen Cohen? Right. Full fat's better.
4:06 Speaker 02 Especially for the metabolic function, for the satiety, for brain function and for bone health. If you go with full fat instead of low fat or fat free. So it's kind of like back to eggs. I'd rather you eat eggs with the egg yolk rather than egg whites. I'd rather you have chicken with the chicken skin and the gristle and the bone than have just pure skim milk. It's, it's more than just calories. And obviously, if we're talking about calories, yeah, it's skim milk, but there is. A hundred calories in this and they do use or they do use um uh low calorie sweeteners. Looks like uh stevia and yeah, so so if I'm looking at ingredient label, I do like to see stevia
4:45 Speaker 02 or allulose or D ribose or erythritol if people's guts can handle a sugar alcohol than like acetylcyanine potassium or sucralose. But when I'm looking at an ingredient label, this is actually pretty clean. I would give this like a like an eight on a one to 10 scale. But I would say if you're concerned about like fat free milk and isolating the proteins from the fats. You know, like a like a either a nut milk, like an almond milk or a coconut milk or an oat milk without the cane sugar added. Or just like using whole milk would be a little bit better.
5:15 Jen Cohen? But isn't that better than having so by the way, Slate, Ben said eight out of 10, so that's still very good.
5:21 Speaker 02 Yeah, it is. It is good.
5:22 Jen Cohen? And for the average Joe, who's not Ben, who is a fitness fanatic, not health, you know, health phenom. It's a really good thing to have because you at least it's getting it's getting 20 grams of protein into somebody who otherwise would not be having that.
5:36 Speaker 02 Yeah.
5:37 Jen Cohen? And it's better than having, you know, a milkshake at McDonald's.
5:39 Speaker 02 Right. I would drink this honestly if I weren't myself a little bit lactose intolerant and I know what if I can have dairy if it's fermented and this is the case for many people. If you ferment the dairy, if you do like a good fermented yogurt or a kefir or those will be the two primary delivery mechanisms for for fermented yogurt, you can do better if you're lactose intolerant. You can also do better on milks that have lower amounts of lactose sugar like goat milk, camel milk, et cetera. But if
6:08 Jen Cohen? What did you say?
6:09 Speaker 02 Goat milk, like a lot of I raise goats, so I we do have goat milk and
6:14 Jen Cohen? How about camel? You said camel milk?
6:16 Speaker 02 It's a thing. You can find it. Yeah.
6:18 Jen Cohen? Stop it.
6:19 Speaker 02 Yeah.
6:20 Jen Cohen? Okay, is that okay?
6:21 Speaker 02 Yak milk.
6:22 Jen Cohen? Where do you buy camel milk?
6:24 Speaker 02 Uh, the camel milk company out of California is where I've gone in the past.
6:28 Jen Cohen? From a camel?
6:28 Speaker 02 Yeah, it's from a camel. Yeah. Surprising.
6:32 Jen Cohen? Do you drink it?
6:33 Speaker 02 Cows from a camel. I have, but it's also really expensive.
6:37 Jen Cohen? I wouldn't. How much is a, how much is a liter of camel milk?
6:40 Speaker 02 Cause I don't really buy anymore, but it is better for the body.
6:43 Jen Cohen? Why?
6:44 Speaker 02 Cows milk because of a few reasons. Lower amounts of lactose, a smaller protein that's more bioavailable than the larger protein found in cows milk. And also a lot of cows are bred now for A1 protein instead of A2 protein. So when you see at the grocery store that you can buy A2 milk, that is milk that tends to produce a little bit less of an immune response in the body. And camel's milk and goat's milk are naturally more like an A2 or they have less of the A1 based protein.
7:11 Jen Cohen? Cause goat's milk, goat milk I see all the time. So are you suggesting to people that they should maybe switch from maybe even their almond milk? Or their oat milk to a goat milk? Would that be healthier?
7:22 Speaker 02 The nice thing about nut milks, again, if you are adding a bunch of, you know, cane sugar to them and, and thickeners and fillers, is that a lot of people who just don't do well with milk in general are, do better with that and they're lower calorie in most cases. There's some that are higher calorie, like I think macadamia nut milk is the highest.
7:40 Jen Cohen? Yeah.
7:40 Speaker 02 But one issue is if you want to be careful with your calorie count, a nut milk is a better substitute compared to a dairy milk.
7:48 Jen Cohen? But that, how about the carrageins in them and all that stuff like that?
7:51 Speaker 02 Yeah. Yeah. And you, you can see on this, on this can, they say no carragein, right? That is a filler that can upset a lot of people's stomachs. So, yeah. And it says lactose free, sucralose free, erythritol free, but I, I don't want to throw them under the bus when I said false advertising. It's technically, they have an enzyme in their lactase that allows you to digest the lactose. So it's not lactose free.
8:13 Jen Cohen? Right.
8:13 Speaker 02 But it's more like they have the carrier agent in there that helps digest lactose. So, so technically by the time it gets into your stomach, it is lactose free.
8:21 Jen Cohen? Okay, that, okay.
8:22 Speaker 02 Theoretically.
8:22 Jen Cohen? Thank you. They're gonna, they're gonna hate me now for even bringing you on this podcast. That I don't care about, but.
8:28 Speaker 02 This one is about, but thi- this one has erythritol in it, which can be a little bit, like if people have like small intestine bacterial overgrowth.
8:34 Jen Cohen? From my friend. I don't know.
8:35 Speaker 02 I don't know. It's not bad, though. It's oxygenated. Yeah.
8:38 Jen Cohen? Okay, this is the next one. This is Magic Mind. I love.
8:40 Speaker 02 Hydrogen infused water, that's good.
8:42 Jen Cohen? That's good. I got that for you, okay? And then, these Magic Minds, I want you, I ca- I'm blind, so I can't even read the ingredients. I do know there's amazing stuff in there.
8:50 Speaker 02 I ate my carrots, I'm gonna see it.
8:51 Jen Cohen? Okay, good. See?
8:52 Speaker 02 Alright.
8:52 Jen Cohen? All your.
8:53 Speaker 02 It's pretty small. So, Magic Mind, New Lixir, matcha green tea, agave, and it's a very small bottle, so a lot of people see agave and they'll be like, oh, that's just a.
9:03 Jen Cohen? A hundred percent.
9:04 Speaker 02 For a sweetener. And agave does have a higher amount of fructose in it. The thing with fructose, fruit juices, fruit sugars, etc., is a lot of people have vilified them. You know, the idea that fructose is a poison. I think Dr. Robert Lustig introduced that concept in his book, uh, about calories.
9:21 Jen Cohen? He believed that, though?
9:22 Speaker 02 So, it is true that fructose can elevate triglycerides and contribute to non-alcoholic fatty liver disease, but only in a case in which the liver and muscle glycogen stores are already topped off. That's at which point fructose starts to spill over and cause issues. So if I'm burning 2,000 calories a day, and I'm drinking 2,000 calories a day of Coke, and that's all that I'm drinking, I would theoretically not elevate my triglycerides or get a lot of the issues associated with fructose because I'm at a net calorie balance. I wouldn't advise it, because you're also gonna be like, you know, you're gonna have low nutrient density and you're not getting enough protein, etc., if you're just drinking Coke. But if people see agave or fructose, or, you know, high fructose corn syrup, sometimes there's some harsh chemicals and things like that
10:04 Speaker 02 used to make that, so that that's, that's a, a whole separate side issue. But the idea of fructose in general is that if you're a physically active person, and you're not overeating, and you're having, you know, fruit juices, uh, you know, fruit in a blender, uh, agave in a drink or whatever, it's usually not an issue unless you're eating too many calories, at which point, fructose can become an issue.
10:25 Jen Cohen? Right. I mean, this is the whole conversation about like, people are like, fruit does not get you fat, please. I mean, this nonsense. Fruit's not gonna get you fat. Yeah, if you eat nine, if you eat like everything else, plus you eat nine pounds of grapes, like maybe I do sometimes, that can be not the greatest.
10:40 Speaker 02 Right. And, and if the fruit is sweet and has a high glycemic index, which grapes do, long-term, you're getting so many insulin surges due to that high sugar content that you could create a long-term state of insulin insensitivity. And then you get some appetite control issues, you get some metabolic issues that long-term could cause problems, even if you're not overeating the grapes or fruit. You're just eating enough to spike your blood sugar repeatedly throughout the day.
