  Robert Eric said, "A healthy outside starts from the inside." And Mark Halperin said, "Sufficient sleep, exercise, healthy food, friendship, and peace of mind are necessities, not luxuries." My guest today is my good friend Shawn Stevenson, who is a graduate of the University of Missouri St. Louis, where he studied business, biology, and nutritional science. He's also the founder of Advanced Integrative Health Alliance, a company that provides wellness services for individuals and organizations worldwide. He's the author of the international bestselling book, Sleep Smarter, which has been so powerful for me and so many people around the world, and is the creator of the Model Health Show. And today, we're talking about his new book, Eat Smarter: Use the Power of Food to Reboot

• 1:10Lewis Howes?

  Your Metabolism, Upgrade Your Brain, and Transform Your Life. Our conversation was so powerful. There's so much data, research that we wanted to share with you, that we broke this up into two parts. So make sure to check out part two coming out right after this one. And in this episode, we discuss why more than 60% of people have chronic inflammation, what the root cause of that is, how sleep affects your brain, and when you have enough or have too little. Also, how our mental health is affected when we aren't taking care of our body and how they're tied together. The link between inflammation in the body and neuroinflammation, which I thought was fascinating, and so much more. And if you're enjoying this, you know what to do.

• 2:10Lewis Howes?

  Welcome back everyone to the School of Greatness Podcast. I'm very excited about our guest Sean Stevenson. In the house, my man. Was pumped about this. We're having you back on to talk about a lot of different things. Nutrition, brain health, inflammation, all that stuff. And I saw a recent stat I want to share with you. By Rand Corporation in 2014, nearly 60% of Americans had at least one chronic condition. 42% had more than one, and 12% of adults had five or more chronic conditions. I'm curious, from your perspective, of all the research you've done, why do more than 60% of people have chronic inflammation and these conditions? What's the kind of the root of this?

• 2:50Shawn Stevenson?

  Inflammation is an underlying component of a myriad of different diseases. But we don't tend to think about it because inflammation seems like, sort of like a ghost in a machine. You know, it's like, ooh, inflammation. But it truly is, you know, if you look at the root word, you know, coming from the Greek and the Latin, it means to set on fire, right? And so there are these...

• 3:09Lewis Howes?

  Inflame.

• 3:10Shawn Stevenson?

  And these are some of the outward symptoms we might think about. It's just like pain, swelling, bruising, burning, aching, those type of things. But there's a massive, the majority of the inflammation that folks are experiencing oftentimes go unnoticed. There are these little kind of chronic low-grade fevers or little fires burning that are contributing to a lot of different metabolic disorders. And the reason that our bodies are doing it is really the inflammation is sending out a distress signal from different tissues to recruit and call in the immune system to support in defending against infections and repair. And the list goes on and on. Inflammation is actually not a bad thing.

• 3:46Lewis Howes?

  Right. It's a healer, right?

• 3:47Shawn Stevenson?

  Right. If we would get a wound, we would never heal without inflammation. If we got an infection, it would be deadly without inflammation. It's an important part of our evolution and our health.

• 3:57Lewis Howes?

  What's the difference between that and chronic inflammation?

• 3:59Shawn Stevenson?

  Right. So what we generally think about is acute inflammation. We think about like a short-term intrusion, maybe an injury or an infection, for example, which the inflammation might last a few hours, even a few days.

• 4:12Lewis Howes?

  Right.

• 4:13Shawn Stevenson?

  But if inflammation is lasting for a long amount of time and also showing up in the wrong places, it can be devastating. And so now we're talking about chronic inflammation. And if we're venturing into chronic inflammation, we've got to look at what are the underlying components? What is creating the fire? What is throwing gasoline on the fire as well? And so if we take one of the conditions that you mentioned, so right now here in the United States, we've got about 242 million of our citizens are overweight or obese.

• 4:41Lewis Howes?

  Out of how many?

• 4:42Shawn Stevenson?

  242 million.

• 4:43Lewis Howes?

  Out of how many?

• 4:44Shawn Stevenson?

  Right around 330,000.

• 4:45Lewis Howes?

  330 million?

• 4:46Shawn Stevenson?

  I'm sorry, 330 million.

• 4:47Lewis Howes?

  So 240 million are obese.

• 4:50Shawn Stevenson?

  So we're looking at somewhere in the ballpark of 70 to even upwards of 80% of citizens.

• 4:53Lewis Howes?

  How is that possible now?

• 4:54Shawn Stevenson?

  Exactly.

• 4:55Lewis Howes?

  How have we gotten this far?

• 4:57Shawn Stevenson?

  Yeah.

• 4:58Lewis Howes?

  How, is it just food is too accessible, or the wrong kinds of foods are too accessible to so many people now? The, you know, social media, is it laziness? Is it, why have we shifted from being a healthy nation, I don't know, probably 60, 70 years ago, to an unhealthy nation?

• 5:15Shawn Stevenson?

  Yeah. It's really a perfect storm of all the things. So the first thing to look at and to ask is what's going on because our genes expect certain things from us. Our DNA expects certain things to have healthy outcomes or healthy cell replication, healthy expression. And so we've got to look at what are the things our genes expect of us? Our genes expect us to move.

• 5:37Lewis Howes?

  Right.

• 5:38Shawn Stevenson?

  For example, we're the most sedentary culture in the history of humanity and recorded human history. We're the most sedentary culture to ever exist right now.

• 5:45Lewis Howes?

  All of humanity or just USA?

• 5:46Shawn Stevenson?

  Right, especially the US. We're the LeBron James. We're the king of sedentary behavior.

• 5:52Lewis Howes?

  We're the Homer Simpsons.

• 5:53Shawn Stevenson?

  We're the dope. Yeah, we're the, you know, we're really leading, leading the league in these things. And so that's number one. Also, our genes expect us to get adequate sleep. And this is something that we've talked about multiple times in the show, but this is, it's built into our evolution. And if you think about sleep, it's very strange because you're incredibly vulnerable, you're unconscious, you'd think we might evolve out of it just for safety. But the thing is, so many wonderful...

• 6:22Shawn Stevenson?

  Absolutely amazing things take place during sleep that we just haven't found a way to replicate. Right, so even with the reduction of inflammation, which we'll talk about more. You know, we have micro glial cells in our brain. Which are, it's kind of the brain's immune system. And it's primarily active when we're sleeping. To reduce inflammation, to clean out metabolic waste. And things of the like, so.

• 6:43Lewis Howes?

  What would you say the five biggest benefits of the greatest night of sleep consistently? Like, what are the five main benefits that you get? If you get deep REM sleep for seven, eight hours a night consistently, no interruptions. No light exposure, all the things you talked about in your other book, Sleep Smarter. What are the five main benefits that come from that versus? You know, interrupted sleep, four hours of sleep, you know. Staying up late with the phone, you know, having coffee late at night, all that stuff. What's the benefits?

• 7:13Shawn Stevenson?

  We'll just power, power pack bullet point these. Number one, and this is because our culture, we are. We, I always like to connect to something visceral. And people, we care about how we look.

• 7:26Lewis Howes?

  Of course.

• 7:27Shawn Stevenson?

  And so.

• 7:27Lewis Howes?

  You're younger.

• 7:28Shawn Stevenson?

  Nobody's, right, nobody's waking up like, I want to look so old today. I want to get my George Burns on. I want to be as old as possible. Or I want to, I want to feel bad today about the way that I, that I, that I look. Or they're not waking up like, I just want to look terrible and feel terrible today. And I've run, in my clinical practice, I never met one person. And people might argue these things and get into a, because of our cognitive biases. I've never met anybody who wants to be unhealthy.

• 7:55Lewis Howes?

  Right.

• 7:55Shawn Stevenson?

  Every single person wants to be healthy. Now, with that said. This is where sleep really comes into the, into the fray. Because over the years, me being a nutritionist, I really. Me being a nutritionist, I thought that food was everything. You know, because it was, it was for me, it was my bridge. But there's many paths to the goal. When you're sleeping, it is the most powerful anabolic state that you can be in. So it's just, you're just teeming with what we call these quote anti-agent hormones. You know, the release of human growth hormone, for example, that really it's also known as the youth hormone. Yeah. You know, and also with in that lane of body composition and overall health and fitness. Researchers at the University of Chicago did a very simple study.

• 8:38Shawn Stevenson?

  They brought folks in and they wanted to see what would happen with their weight loss. They put them on a calorie restricted diet. And they wanted to see what would happen with weight loss when they were well rested versus when they're sleep deprived. And so they put them under both conditions. And I love studies that do that. It put people under both conditions to see what would happen. And so they allow folks to get eight and a half hours of sleep in one phase of the study. And they tracked all their metrics, their weight loss, et cetera. And then they sleep deprived them for the other phase. So they was getting eight and a half hours, now they're getting five and a half hours. Tracked all their metrics. Same group. Same group on the same exact calorie restricted diet. Same calories, yeah, everything. But when they were sleep deprived, when they were sleep deprived versus when they were adequately rested.

• 9:21Shawn Stevenson?

  When they were getting enough sleep, they lost 55% more body fat just by sleeping more. That's crazy. It's, it doesn't even make sense. Were they working out the same or was it like no movement? What was it just like? Everything is the same. This is what I love too. It's a ward study. So they're under the conditions where they can track everything. Now here's another part of the study I don't often talk about is that they actually did biopsies. So they actually took Fat cells. Fat cells to see what would happen with their fat cells under the different conditions. And what they came to the conclusion was that your fat cells actually need sleep too. Because when the fat cells were not, when you, when they weren't adequately rested. Their fat cells actually became more insulin resistant, which should become like, that should put up a huge red flag.

• 10:03Shawn Stevenson?

  Because insulin resistance is one of the classic signs is carrying more belly fat, right? So the fat cells themselves, looking at them versus when you're well rested versus when you're sleep deprived. Your fat cells themselves become insulin resistant. And it's just going to lead to downstream problems with your liver, lipogenesis, the creation of new fat. The list goes on and on. So that's just one part, one thing. So number one, number two, the cognitive performance. And I love this study. This was published in The Lancet. And they wanted to see what would happen when physicians, they took physicians and had them to complete a task. And tracked all their numbers. And they sleep deprived them for 24 hours, which is not abnormal in the field of medicine.

• 10:43Shawn Stevenson?

  And had them to complete the same task, which is a simulation of different like surgical type of simulation. They made 20% more mistakes doing the exact same thing. And it took them 14% longer to do the exact same thing. Alright, so and this is a big problem in our culture. Again, we mistake being busy for being effective. Right? And so that's the number, that's the number two thing, the cognitive performance. Number three, and this, it parallels with cognitive performance is the health of our brain. And so researchers at UC Berkeley did brain imaging scans and, you know, we talked about this before, but they actually looked at the sleep deprived brain, just again, 24 hours of sleep deprivation. And the part of the brain that's associated with executive function, right? So.

• 11:24Shawn Stevenson?

  Uh, decision making, distinguishing between right and wrong, social control. So the prefrontal cortex, the more human part of our brain. That part of the brain goes cold. The activity of that part of the brain just literally as we're more and more tired just shuts down. With a lack of sleep. With the lack of sleep, coupled with more activity in the amygdala, which is very much more primitive, driven by emotion. Very much concerned with survival of self. And so that part of the brain just lights up like a Christmas tree or Las Vegas sign. You just came back from Vegas. So these changes happen in the brain very quickly. And that leads into. Number, well, number three, reduce cognitive performance. So being able to manage our emotions, being able to manage our decisions.

• 12:07Shawn Stevenson?

  And then we'll go to number four is is gonna lean into this as well with the brain function. Is, I talked a little bit about this earlier, during sleep is when your glenphatic system. Which is the brain's waste management sys, waste management system. Cleansing it all out. Is 10 times more active when you're sleeping than when you're awake. So and your brain is doing literally trillions of activities every second. And there's a lot of metabolic waste that takes place. And you have to have this cleansing system, this cleaning system. Or you're gonna have a buildup of things like amyloid beta plaque, for example, which that is strongly, strongly correlated with Alzheimer's disease. It's an inability of the brain to clean itself. And also insulin resistance in the brain, we could talk about later.

• 12:50Shawn Stevenson?

  But we're wondering again, why are these issues going up? Why is brain inflammation going up? These are the things, are we getting enough sleep for the processes that normally just naturally want to happen? They do it on their own, are we getting that? The final thing. So four is the cleansing. Right, cleansing, cleaning, so this is associated with disease prevention of the brain, longevity of the brain.

• 13:15Shawn Stevenson?

  And number five, you know, this is tough, there's so many different, different things that this can benefit. But I would say for me and you as well, like we want to be able to perform. You know, we want to be able to use our body and our mind to compete, to get out and to play, to have a good time. And one of the fun things I talked about in my, in my first book, Sleep Smarter, was research that was done on basketball players, collegiate basketball players at Stanford. And they found that simply by increasing the amount of sleep that they were getting, not training more, not doing anything else differently, this shaved a full second off of their sprint time, just by increasing their sleep. Wow. They improved, significantly improved their free throw shooting and their three-point shooting,

• 14:00Shawn Stevenson?

  just by getting more sleep. Alright, and these are things that we just kind of, on a periphery, you kind of know that. But at the same time, are we utilizing it? So some of the greatest athletes in the world right now, sleep is a part of their training. LeBron James, it's a part of his training. Usain, Usain Bolt, same thing, it's a part of his training. Now Serena Williams, the list goes on and on and on. These things weren't talked to us when we were in high school. It was just like. Get up before you ever left. Yeah, right, just go, just go right into somebody, you know what I mean? Make a play, make a play.

• 14:34Shawn Stevenson?

  But today, you know, it's really built into the, into the system, also the strength training programs are built into the system. Uh, which is beautiful because again, when we were in high school, it was very, I mean, some stuff was starting to take place with folks being in the weight room, but it wasn't a big emphasis. Whereas now, if you look at different sports like. A good friend, which I'm, it's so weird for me to say this right now. This is like the coolest thing. I've actually got chills. Ozzy Smith, right? So having the opportunity.

• 15:01Lewis Howes?

  Same with Icon, man.

• 15:02Shawn Stevenson?

  Icon. When I was a kid, my two idols were Ozzy Smith and Michael Jackson.

• 15:07Lewis Howes?

  Wow, yeah.

• 15:08Shawn Stevenson?

  I tried to wear the Thriller jacket to school and I got drove. That was not a good look, but Ozzy Smith could be my role model and I could just, I wanted to, to play. I wanted to compete, play baseball. And so I actually met him at the gym and so he was there. I think he was probably in his, around in his mid sixties maybe at the time. Uh, but he was there getting strong, like, and he was one of the first, if not the first high level elite baseball players to really embrace strength training. Way back in the eighties. And the reason that he did it, funny enough, was he tore his rotator cuff and he didn't want to be out. Like this was back in the day where it's just like literally you pat, you do whatever it takes to get on the field. And he wanted to be there for his team. And so he just tried, had to find out a way to strengthen everything around it.

• 15:52Shawn Stevenson?

  Because he didn't want to have surgery, he would have been out for a year at the time. And now, you know, of course surgeries have advanced tremendously since then. But, so he found that he strengthened everything in his shoulder, but also he started throwing from a completely different arm angle. And still won 13 consecutive gold gloves.

• 16:08Lewis Howes?

  It's crazy.

• 16:09Shawn Stevenson?

  It's crazy. It's crazy.

• 16:11Lewis Howes?

  Back flipping at the same time.

• 16:13Shawn Stevenson?

  Right. He's out there back flipping with the glove on.

• 16:15Lewis Howes?

  It's cool.

• 16:16Shawn Stevenson?

  So powerful. But it's a big part of what our genes expect is to, is to be strong in some different domain. And we talked about this before the show. That translates over into our lives as well, you know? So that's strength. If you can train your body and your mind, because your mind is in play too. Life gets a little bit easier in many aspects. You know, like you feel more physically ready to handle whatever life throws at you. You know, and so in the context that, that final one is being able to, to perform at a high level, to recover from the training that we do. All the magic happens when you're sleeping.

• 16:52Lewis Howes?

  Absolutely.

• 16:52Shawn Stevenson?

  When you're up in the gym and, and training or you're out on the field competing, you're just tearing your body up. That's all catabolic stuff. You get the anabolic reward when you go to sleep.

• 17:01Lewis Howes?

  When I was interviewing Andrew Huberman, the neuroscientist out of Stanford, he was saying that even learning a new skill. It's like the neurons connect when you're sleeping. Like, when I do Spanish class sometimes, I'm just like, I'm not getting this. You know, there's moments where I'm like, gosh, this hurts my brain, it's so challenging. But then I come back the next day or two days later, I'm like, oh, I'm, you know, I've connected the neurons. Or it's like, in your sleep, things are moving and processing for you to really connect those things you're learning, those new skills, those challenging things. So I think it's, and if I wasn't sleeping, I probably wouldn't connect the dots on a new skill. So something to think about there as well. I'm curious about this.

• 17:38Lewis Howes?

  Have you seen a study around, or any research around how our belief about our identity? How we view ourselves in the world? Whether we think positively of ourselves, we have confidence, we believe in ourselves, or our lack thereof, we have a bad view of ourselves. Do you, is there any research about how that affects the brain? Our actual mindset of the brain and ourselves?

• 18:04Shawn Stevenson?

  Absolutely.

• 18:05Lewis Howes?

  Have you seen any of this?

• 18:06Shawn Stevenson?

  The number one driving force of the human psyche is to stay congruent with the ideas that we carry about who we are. Every, every thought that we think, every action we take is really correlated with who we believe ourselves to be. And this is why change can be so uncomfortable. You know, when we start to think things that, I, I don't think that way, or these are things that I don't do, our, our physiology, this stuff really gets hardwired into us. And so it creates discomfort. Because we're literally going to start creating new neural pathways and potentially start to break down old ones. And a mutual friend, Dr. Caroline Leaf, and I love her so much. And she's really brought to the forefront. And I talked a little bit about this in Eat Smart in my, in my new book, and how our thoughts really affect our biology,

• 18:51Shawn Stevenson?

  even how food affects us based on our beliefs about food. And so, one of the biggest things to really come from her work, that unfortunately, it wasn't embraced, even though she's been in the field for 40 years, she really knows her stuff. And it's affected so many different lives. But it takes time for kind of collegiate training to, to change, for the books to change. But one of the big takeaways is, our thinking, your, your thoughts create your brain. Really? The process of thinking itself is creating your brain. And we think that the brain is in and of itself just kind of off-shooting our thoughts. Now, we can absolutely have thoughts stored in our brain, but thinking is so much bigger. Our mind is creating our brain.

• 19:36Lewis Howes?

  So, thinking is a part of the mind. Is that right?

• 19:40Shawn Stevenson?

  Also, the brain as well.

• 19:41Lewis Howes?

  It's both.

• 19:42Shawn Stevenson?

  Yeah, it's kind of within the brain, then we start to create it. She shares, I don't know if she did this with you, but she brings up the little trees and all these things.

• 19:48Lewis Howes?

  And the branches and this.

• 19:49Shawn Stevenson?

  Yeah, so we start to create these with a thought, little thought trees start to bear fruits. But we can supersede it. Your mind is bigger than just your brain. We tend to think that because everything is kind of up here, but our mind is in our toe as well. And our mind is just so much. Yeah, in our gut.

• 20:06Lewis Howes?

  I've had Dr. Emeron Mayer on.

• 20:09Shawn Stevenson?

  Yeah.

• 20:10Lewis Howes?

  And he was talking about the mind in the gut and how it's all connected to the brain as well. The gut-brain and the brain-brain and fascinating.

• 20:19Shawn Stevenson?

  It's so fascinating.

• 20:19Lewis Howes?

  The mind is connected throughout, all throughout your body as well.

• 20:22Shawn Stevenson?

  Yeah, so, for example, even our heart, within the gut, the human brain itself is just an absolute universe of neurons. So, it's like eighty-four billion neurons, right? I was thinking about human cells overall. So, we have about eighty-four billion neurons in the brain. We have about a hundred million in the gut. All right, so this is like nerve tissue. It's like a mass of neurotissue in the gut. But the heart also has neurons as well. So, it's called, and anybody can go to Dr. Google and look this up, it's called the heart-brain. All right, so your brain, your heart actually has this kind of ability to think. And there's this electromagnetic energy that it's expressing. And there's a field also. It's called a tube torus that's been monitored

• 21:07Shawn Stevenson?

  that's expanding beyond our body to be able to see this. And if folks want to check out the work from HeartMath Institute.

• 21:13Lewis Howes?

  HeartMath.

• 21:14Shawn Stevenson?

  HeartMath Institute is phenomenal. I've been, you know. Probably for about ten to fifteen years, uh, connected with, with HeartMath Institute. It's just absolutely phenomenal.

• 21:24Lewis Howes?

  So there's a field around the heart. Does that mean like quantum physics we're talking about? Or is this something else?

• 21:30Shawn Stevenson?

  So.

• 21:30Lewis Howes?

  What is this field, an energy field?

• 21:32Shawn Stevenson?

  We'll keep it real, real simple first, which is if we think about the elec- the electrical energy that the heart is kicking off, like when you, when you're in the hospital, right? And you see the monitor, boop, boop, it's not reading the, the, the, the smoke coming off your heart, it's reading the electrical energy that's coming off the heart, right? So we got EKGs and things of that nature. So we can read the electrical currency that the body is, is throwing off.

• 21:59Lewis Howes?

  Wow.

• 21:59Shawn Stevenson?

  Your body is just teeming with energy. And there's even a form of energy that we generate, it's called piezoelectricity, right? Just from moving, we're generating energy and electricity. So just from a very simplistic level, the heart is, is kicking off energy that we can't see. That's the thing about it, right? It's, it's, it's emanating from beyond us. Even our skin is emanating energy. We just see a certain spectrum of light as humans. We see a certain spectrum of energy.

• 22:26Lewis Howes?

  How far does this energy go beyond the body?

• 22:29Shawn Stevenson?

  So the two toruses from HeartMath Institute's data and being able to, to measure it and monitor it, it can be upwards of, at last checked, around eight feet from your body. And so now this is getting into some freaky stuff, right?

• 22:41Lewis Howes?

  Give it to me.

• 22:43Shawn Stevenson?

  And I'm a very logical, analytical human, so seeing is believing for me. But then we get into, there's many things that are just, and also I'm very open-minded as well. And there's many things that we don't understand. But when we talk about people being in your space and you picking up people's energy and interacting, and that stuff is very real. You know, you can pick up people's vibes, you know, bad vibes. So we don't want to downplay that because other, other species of animals, they have that bigger connection. And we can, we can attribute like bees, for example, you know, in this quote hive mind, but we throw that away when it comes to us. And so for me, for years I've been seeking to find, how can I explain this to people to make sense? Because I'm a very solid thinker,

• 23:26Shawn Stevenson?

  you know, I'm a very logical person. And one of the things I came across was Princeton University researchers, they found that they just took two strangers and they put them together and they had them to just chat. And they found out within a matter of minutes, all they had to do was create some rapport and their brainwaves started to sync up.

• 23:45Lewis Howes?

  Come on.

• 23:46Shawn Stevenson?

  Their brainwaves started syncing up just by having rapport and talking to another person. We start syncing up. And this is, this happens all the time.

• 23:55Lewis Howes?

  What does that mean that we sync up? The brain is what?

• 23:58Shawn Stevenson?

  So it's like it's, again, this is, this is expanding beyond our kind of normal concept of what the brain is. Because it's not just the brain, it's also the mind that's controlling the brain, right?

• 24:11Lewis Howes?

  The mind is controlling the brain. The brain isn't controlling the mind.

• 24:14Shawn Stevenson?

  We, we tend to think that it's the brain that's running the show.

• 24:16Lewis Howes?

  But it's not, the mind. So what is the mind?

• 24:19Shawn Stevenson?

  That's, put Dr. Caroline Lee's episode. She could dive in deeper on, on what that is.

• 24:25Lewis Howes?

  Right.

• 24:26Shawn Stevenson?

  Uh, from a more clinical aspect. However, I'll tell you this.

• 24:33Shawn Stevenson?

  The mind is, it's something that we're still having a hard time to identify what it is and where it's located. That's the thing.

• 24:40Lewis Howes?

  Where is it? Like here, is it around here? Is it in our space?

• 24:43Shawn Stevenson?

  It's definitely not in your brain alone. Your, your mind is everything about you. Everything about you. We, the problem is that we tend to think that the brain is the master controller.

• 24:53Lewis Howes?

  It's not.

• 24:54Shawn Stevenson?

  It's not.

• 24:54Lewis Howes?

  What is?

• 24:55Shawn Stevenson?

  The mind is.

• 24:56Lewis Howes?

  Okay.

• 24:57Shawn Stevenson?

  The mind. And we still are trying to, to dictate what the mind is. It's so big and it's so beautiful. It's expansive. So this is the adventure of all this stuff is like, we get to learn, we get to discover. But as soon as we think that we got it figured out.

• 25:12Lewis Howes?

  No.

• 25:13Shawn Stevenson?

  That's when everything starts to go wrong.

• 25:15Lewis Howes?

  And also it sounds like if the brain isn't optimized through sleep, through nutrition, through healing the inflammation, the chronic inflammation, if that's not optimized, your mind is not going to be optimized.

• 25:25Shawn Stevenson?

  Yeah.

• 25:26Lewis Howes?

  You're going to be thinking poorly, you're going to be acting poorly, you're going to be tired, all these different things. So if you want your mind to be sharp, you gotta make sure your brain is healthy and recovered and healed. Is that what I'm hearing you say?

• 25:38Shawn Stevenson?

  It's, it's true, if we're just gonna be, again, looking at this from a very foundational, simple principle, it's much more difficult to think the thoughts that we want to think when we don't feel well.

• 25:49Lewis Howes?

  Right. When we don't feel well, we start to think bad thoughts.

• 25:52Shawn Stevenson?

  It's just, it just comes together.

• 25:53Lewis Howes?

  It's hard.

• 25:54Shawn Stevenson?

  Comes together because of our, so much of our biology is driving our lives, you know, how we feel. But this is the thing, and everybody's seeing this example. We can think externally of our biology. We can change our thoughts and change what's happening with our biology instantly. Because every thought that you think has correlating chemistry that's released. Really? Give me an example. So, right now. Think about your wife. Yeah. In a loving way. So I'm gonna start releasing a little bit of oxytocin. Uh huh. You know, a little bit of, maybe a little dopamine, you know, a little serotonin. In the brain. Yeah. Which then releases. But also depends on the thoughts as well. If it's some sexy thoughts, it might be a little, get a little adrenaline or epinephrine produced.

• 26:37Shawn Stevenson?

  You know, just like that, a little bit more aggression might come forward, you know, it just depends. But also if, for example, we have a, a, a thought where something bad is happening right now, where we're thinking about, you know, maybe we're worried about somebody that we care about. Maybe they've been in some type of, an incident of some sort. And, but maybe we heard some news about it, but it's not true. Okay, so maybe we, we heard that somebody that we love got into an altercation, right? And we're just like, you know, really upset, like, oh my, I can't believe this happened, I can't believe whatever. And we can start to produce these chemicals associated with that stress. So, much more cortisol, right? So a lot of people know about cortisol. Cortisol's not a bad guy. We've talked about this before.

• 27:21Shawn Stevenson?

  It's a big part of vibration. Too much of it consistently hurts you. Especially in chronically. So, we start to relute, release all these neurotransmitters, neuropeptides, hormones, all driving us towards worry, fear, anger, regardless if the situation is real or not. Right. That's the rub. We make it up. So we can think external, we can think beyond our current circumstances and change our biology. But if our biology is in a tough place, it, it's harder to keep trying to do that. So our thoughts shape our biology. Our thoughts shape our feelings. Your thoughts create your body. Your thoughts create the body. So now we get into. Wow. I'm bring, I'm gonna bring her up one more time. Yes. Caroline's work. She's great. Yeah, so we, that, we had a great conversation about that as well.

• 28:06Shawn Stevenson?

  And actually, um, uh, an interview that I did with her, it came out recently and we got, we, we, we, we put our toes in, in that conversation a little bit more. Because this, again, this is kind of difficult for us to, to, to think about today because we've been so inundated with. The genetic dominant theory that our genes are controlling our lives. And now today, of course, I believe just about everybody listening has heard the term epigenetics at this point. And how these are above genetic controls, like epidermis, like your skin, the outermost part of your skin. So epigenetics is controlling your genetic expression, right? And so humans collectively have got maybe 20,000, 22,000 genes collectively. But I think that that's going to play out and you're hearing it here first.

• 28:51Shawn Stevenson?

  I think that that number is not quite accurate, but when they did the Human Genome Project, that's what they discovered. Right. But why are we so different? It's because of the expression of the genes. There can be a thousand different out picturings of one gene. And it could code or express what we would deem to be something negative. But even the negative things are trying to push us towards health. There, our body is always adapting, trying to help us to survive. Trying to realign us and saying, this is not good. You need to pay attention to this and fix it. Yeah, even with obesity, our bodies are trying to save us. How so? Trying to save us. So for example, when we, when we bring in an abnormal amount of sugar, like the way that humans evolved, we didn't have access to sugar like that.

• 29:33Shawn Stevenson?

  You know, if you come across a beehive or something like you're going to risk, you're going to risk getting stung to get some of that.

• 29:41Shawn Stevenson?

  But today, we've taken that. Just here, eating all day long, everything. It is so remarkable how, and for me, it's just, it's a very simple principle of biology. When do we start getting sugar accessible in this country? When was, what year or decade was this where it's like, oh, sugar is available now? Here's the beautiful thing, humans have, we've always had a hankering for sugar, like through our evolution. We'd go towards, like I said, yeah, we'd go for those things especially, but also is available for some cultures, only certain times of year, for example. And so you would rack up on it as well. And now this is important tenant as well. Because, and there's a reason for this. The human brain itself.

• 30:26Shawn Stevenson?

  If we think about the blood-brain barrier that protects the brain. It only allows in certain things, certain nutrients. It only has gates for certain gases like oxygen, for water. Only certain nutrients get into the brain. The brain has its own exclusive diet. But there are a lot of sugar gates. Your brain will gladly confiscate Harvard researchers uncover this. Your, your, your brain will gladly sop up half of the sugar that you take in in the meal.

• 30:53Lewis Howes?

  You take 50 grams of sugar, 20, 50% of that, 25 grams.

• 30:56Shawn Stevenson?

  25.

• 30:57Lewis Howes?

  Going into the brain.

• 30:58Shawn Stevenson?

  Going to your brain.

• 30:58Lewis Howes?

  How's it, where's it going? Does it go throughout all the brain? Does it go to a section of the brain? What happens? Is it, and it's just filtered throughout and you're just on a sugar high?

• 31:06Shawn Stevenson?

  Yeah, so even the term sugar high, like it sounds, it's kind of funny, but that's not funny. It's not funny. Because what happens is, so there are these protein gates that allow the sugar to transfer over from, through the blood-brain barrier into the brain itself. And yeah, because many of the neurons run off of glucose. So your brain is like, look, give me that. We got, we got stuff to do. Let me, let me take all of it. But what happens is, over time, is it starts to create insulin resistance in the brain as well. All right, so this is one of the biggest issues facing our world today. And if we get in the conversation about inflammation, neuroinflammation. I believe is the most troubling issue that we're facing as a society.

• 31:47Shawn Stevenson?

  But it's, it's a, it's a hidden overlooked issue because the brain is so protective. We don't really know that this is going on until oftentimes it's too late. Because the brain itself, we talked about the symptoms of inflammation. Pain, swelling, burning. The brain itself doesn't have pain receptors. So your brain can tell you about pain in your, in your pinky toe. Or on your, you know, pain in your neck. But pain within the brain itself, it doesn't have pain receptors.

• 32:14Lewis Howes?

  What about like a migraine or something? Is that not?

• 32:16Shawn Stevenson?

  Migraines are not the brain directly expressing pain. It has a lot to do with, now, there is, this is a little bit more complicated. There is, there, there are some offshoots of things happening within the brain with migraines. Let me be clear. So let's just take, um. The borderline, migraines are different also. People who experience migraines, they know that it's different. But from a headache, but we'll just take that borderline experience, maybe like an acute migraine or maybe a tough headache. What it really is, is the blood vessels that surround the, the brain, that surround the, your skull. All right, not the brain, but that's surrounding your, your neck and your shoulders.

• 32:59Shawn Stevenson?

  And so muscle spasms and things of that nature can start to kind of cut, cause restriction. Right? So, but there can be some electrical storms taking place in the brain for sure.

• 33:09Lewis Howes?

  Interesting.

• 33:11Shawn Stevenson?

  Anyway, so the brain itself doesn't experience pain. So this is why, for example, there's, you know, you can have a brain surgery.

• 33:20Lewis Howes?

  Not feel like, you're awake.

• 33:21Shawn Stevenson?

  Yeah.

• 33:22Lewis Howes?

  That's nuts, isn't it?

• 33:23Shawn Stevenson?

  So weird.

• 33:24Lewis Howes?

  Wasn't there someone who was like playing violin on a, on a brain surgery that like opened the head and it was like, to see if she could still play or make sure that it was.

• 33:31Shawn Stevenson?

  That's like some total recall stuff.

• 33:32Lewis Howes?

  That's crazy, man.

• 33:33Shawn Stevenson?

  Whereas I know, that was crazy.

• 33:35Lewis Howes?

  It's like.

• 33:35Shawn Stevenson?

  Yeah, it's, it's amazing, man. But these, these are really overlooked, simple principles, but going back to that tentative inflammation. So if the brain can't experience the pain, how do you know when it's on fire? How do you know when it's?

• 33:47Lewis Howes?

  The brain, you don't know.

• 33:47Shawn Stevenson?

  Yeah.

• 33:48Lewis Howes?

  Until it's too late.

• 33:49Shawn Stevenson?

  You don't know, but there are downstream symptoms.

• 33:53Lewis Howes?

  I'm feeling this in my, my face, my arm, my back, like something, my gut doesn't feel good. There might be a.

• 33:59Shawn Stevenson?

  And it's that constant super highway of the brain, body connection. Right? So these researchers at Albert Einstein College of Medicine, they found that neuroinflammation is a double edged sword for nutritional diseases, metabolic diseases. All right, so what that means is inflammation in the brain is one of the primary causative factors of obesity.

• 34:21Lewis Howes?

  Ah, so when you're, when you have inflammation in the brain, you're more likely to be obese.

• 34:26Shawn Stevenson?

  And obesity is a causative agent for neuroinflammation.

• 34:30Lewis Howes?

  So they both hurt each other.

• 34:31Shawn Stevenson?

  So you're getting into this double edged sword or vicious circle. And this is why, again, we, we tend to.

• 34:40Shawn Stevenson?

  Downplay or belittle people who are struggling with obesity, for example, and not knowing how many programs out there are telling you, we need to target the inflammation in your brain for you to get well, for your metabolism to heal.

• 34:52Lewis Howes?

  Yeah, the work that Dr. Daniel Amen is doing, which is, you know, he says the bigger the body, the smaller the brain. You know, your brain starts to shrink. I think that's accurate, if I remember, but it's like, and you want to really focus on both the nutritional side and the brain, make sure the brain is healthy. And you can heal and recover a lot of the brain, from what I'm learning from my scan that I took there. There are ways to optimize the brain, even if you've hurt it in a big way.

• 35:18Shawn Stevenson?

  Yeah, that's the beautiful part about us. And Daniel's a really good friend. If there's anybody who knows, it's him. He has the biggest database of spect imaging scans. He's looking at the brain. He's not just making it up. And so, this is a fact. I talked about this in Eat Smarter as well. He actually wrote the cover quote for Eat Smarter.

• 35:37Lewis Howes?

  Nice.

• 35:38Shawn Stevenson?

  Man, I'm so grateful to have a friend like him, because he's just such a wealth of knowledge. But one of the really interesting things is that as your waistline grows, your brain shrinks.

• 35:48Lewis Howes?

  That's crazy.

• 35:49Shawn Stevenson?

  Right, so we see that. And particularly the gray matter of the brain is going to be inhibited.

• 35:55Lewis Howes?

  So obesity, what does that mean? Obesity impacts the quality of the brain? And what if 65, 70% of Americans are now obese? That means they have smaller brains, which means they're not going to be able to perform as well. They're going to be more temperamental. They're going to be more mentally unwell, I'm assuming. Have more mental health issues, potentially more depression, anxiety and stress and overwhelm, based on obesity.

• 36:21Shawn Stevenson?

  You said it, man. This is where it really gets scary, because we often, we look at the condition and we just like, and me being in this field, I've been in this field almost 20 years. And we'll just say, if I got 30 family members.

• 36:37Shawn Stevenson?

  Twenty eight of them are obese. Growing up like I grew up around.

• 36:40Lewis Howes?

  Right, obesity, yeah.

• 36:41Shawn Stevenson?

  That, you know, but for me, my genetic cards were a little bit different because I ate worse than everybody. But I had asthma, you know, I had.

• 36:49Lewis Howes?

  Got you.

• 36:50Shawn Stevenson?

  Um, of course, you know about the degenerative disc condition, you know, so I had advanced arthritis when I was just a baby, really. I was.

• 36:57Lewis Howes?

  You had other, you had other painful side effects than obesity.

• 37:01Shawn Stevenson?

  Yeah.

• 37:02Lewis Howes?

  By eating.

• 37:02Shawn Stevenson?

  Expressions, but that fat, my fat genes kicked in.

• 37:06Lewis Howes?

  Yeah, eventually after twenty five, thirty.

• 37:07Shawn Stevenson?

  When I got to twenty and I stopped because for me also, it's always very active as well. And so now I've got this chronic condition diagnosis, so called incurable, nothing I can do about it. And now I was given a permission slip to do nothing, you know, and so that's what I did. You know, so again, again, in that state of learned healthlessness.

• 37:26Lewis Howes?

  Now, I'm going to ask something that might be controversial. There's a big movement of the accept yourself, self-love. No matter how big you are, small you are, like just love yourself for where you're at. And, you know, how do we, how do we love and accept people for where they're at without shaming them? But also encourage them to improve the quality of their health. So that their brain gets bigger and healthier, so that they can live longer, so that they can perform better because from what I'm hearing, obesity is not something that's going to make you live longer and healthier.

• 38:02Shawn Stevenson?

  Yeah, I love this question, man, because the first thing is, I love it because this conversation is bringing to light the fact that we've been inundated with an idea of what beauty looks like. We've been inundated with an idea that thin is better for many years. We've been inundated with an idea that you've got to look a certain way. You've got to have a certain, certain complexion, certain eye color, whatever the case is to be the epitome of what beauty is. And humanity is so beautiful, so diverse, so, so gorgeous, so magical. You know, there's so much beauty and expression and there are cultures that are just thicker than a snicker by nature. You know, if you talk about, you know, folks, um.

• 38:44Lewis Howes?

  Polynesian cultures.

• 38:46Shawn Stevenson?

  Polynesian culture, for example, incredible athletes and they just.

• 38:51Shawn Stevenson?

  Right out of the gate, it's gonna have a little, be a little bit thicker. But that's beautiful. It can be beautiful. It can be healthy. It depends on your genetics, on how much weight you carry and how healthily you can carry it. You maintain your insulin sensitivity, the health of your brain, the longevity, the list goes on and on. There are different, and this is one of the things that I really brought to the fold with Eat Smarter is your unique metabolic fingerprint. And a part of that metabolic fingerprint is honoring your genetics, right? And so with that said, shifting the culture right now to honor our diversity and our variation of what beauty looks like. And not being, having this idea that having some body fat is something that's wrong or ugly. That's, that's absolutely terrible thing.

• 39:35Shawn Stevenson?

  The other part, and it's not even a but, it's and, so we have that, that acknowledgement. And we have to understand that if you have insulin resistance, you're prediabetic, or you're diabetic, or you have heart disease. Or you have neuroinflammation that we're talking a little bit about. You have allergies and asthma. List goes on and on and on. Advanced arthritis, all these different conditions, all these underlying things that can take place. This is going to, in many ways, destroy your quality of life. And we want you to be healthy and a unique expression of what beauty is.

• 40:11Lewis Howes?

  Yes.

• 40:12Shawn Stevenson?

  That's it.

• 40:12Lewis Howes?

  You don't have to be perfect and have a six pack and have like a certain amount of body fat, but

• 40:19Lewis Howes?

  you gotta live a long time. If you wanna live happy and healthy and not feel these kind of mental health issues as well. This will help that if you're healthier physically.

• 40:28Shawn Stevenson?

  Absolutely, because that goes hand in hand with all the other things that we're seeing as a society. Where we're losing so many people prematurely, you know, we're losing lives, but not just that. Not just the actual loss of life, but the loss of life where people are still living.

• 40:43Lewis Howes?

  Ooh, what do you mean by that?

• 40:45Shawn Stevenson?

  When we fall into these places, I lost my grandmother, the love of my life, the love of my life.

• 40:54Shawn Stevenson?

  My grandfather, her and my grandfather were an entity. You know, and so we just had some friends over yesterday and they were like, you guys are the only married couple that we really, that we know that are like, and I'm just wondering how I, how we have, what we have, my wife and I, when I didn't have any examples of a healthy married couple. Like I just pretty much never seen it, never saw it. But I lived with my grandmother when I was a little guy, when I was, when I was, you know, between the age of about, we'll say, four to eight years old, right? So it was very formative and for me, that was my earliest memories and they're an entity and they, and I'm sure they had disagreements, but they ne- I never, all I saw was love. All I saw was them like, his arm around her and just affectionate. She loved him literally to death.

• 41:38Shawn Stevenson?

  And so he ended up having multiple open heart surgeries. And he was, you would think again, he was, he was hunting, he was foraging, very like outdoor guy, but he was living under chronic stress in the city. He was a country boy, right? And so he was, you know, in this environment, but also when he first, when he was noting like, okay, you got a high blood pressure. He also was a very angry guy, you know, well, he, he dealt with anger. Yes. But not towards us, you know, but just his conditions that he came up around. So now this is very important. The physician, based on his prelim- preliminary blood work, which again, I wish I could have been there and to, to be able to intersect this. It was like, okay, you gotta cut the fat.

• 42:23Shawn Stevenson?

  You need to switch out that butter and start to have this partially hydrogenated vegetable oil, which is Country Crock. The first time I saw Country Crock was in my grand- my grandmother, grandfather's house. And he went from having some blood work issues to having a heart attack. Oh, man. To having open heart surgery, to him dying early. Was he obese or no? No, he looked incredibly fit. Wow. But that was his. Do you think it was more stress or the nutrition?

• 42:51Shawn Stevenson?

  Primarily stress, I feel. Stress and then also the nutrition that was added in on the recommendations of. Didn't help. Right, so we're going from something that's quote natural that humans have been having for centuries to something that was brand new and invented. You know, and all the fat. I remember my grandmother getting him like the low fat peanut butter. And I remember, uh, once I got older, I, I went to their house, I looked at it, it was, it said fully hydrogenated, um, vegetable oil in the peanut butter. And so it's like, it's basically exposing it to more hydrogen to try to create, to extend the shelf life of it. It kind of makes like a, in a strange way, a vegetable oil plastic out of it. Yeah. But anyways, so bottom line is this, and I'm glad I got admitted to talk about this

• 43:34Shawn Stevenson?

  because it's, it's, it's tough to talk about, but she, she was around for a while. She was there at my wedding. I felt like she stayed. Wow.

• 43:44Shawn Stevenson?

  I felt like she stayed to make sure that I was in good hands, you know? Wow. Uh, but shortly after that, she died from a, a overdose. She was, uh, depressed, I didn't know. Really?

• 43:58Shawn Stevenson?

  And, you know, with, with the story goes, you know, I don't know if she did it on purpose or not, but, you know, she, she took her medication and she died.

• 44:09Shawn Stevenson?

  Shortly after wedding, or? Yes, not, not too long after, maybe, you know, maybe a year later. Yeah. But, you know, I lost, and I lost the love of my life outside of my wife to depression. And, you know, when he left here, like, really her identity was so tied to him. You know, she loved him so much.

• 44:31Shawn Stevenson?

  Man. Yeah, so when I'm talking about this stuff, but also her health was going down as well, and I'm just now really starting to hit my stride in understanding this field and helping a lot of people. And, you know, I didn't know, like, my grandmother had diabetes, she had this, she had this, that issue, she had like the whole pill cabinet. Oh, man. And for me, growing up in it, it was normalized, you know? And yet we're treating symptoms. And so when we're not in a good state of health, the, the depression, it is just, it's more, it can be more invasive. Yeah. It can be harder to deal with, they come together, so. Hard to deal with, hard to get out of it. Yeah, my point that I want to share is.

• 45:14Shawn Stevenson?

  When we're venturing into these outward states of inflammation, because even our fat cells themselves are an inflammatory factor. They're essentially, they're putting out a distress signal that's letting your body think in a sense that you're infected. And the fat cells themselves are creating inflammation, right? And we talked about that again, that systemic chronic inflammation. It's just literally checking all boxes for a bad event to take place. Whether it's depression, whether, which depression now we've got sound date on having inflammatory component, depression, heart attack, stroke, dementia, the list goes on and on and on. And a big catalyst for this, about 400,000 people die each year from obesity-related conditions. And it's just a footnote.

• 45:58Lewis Howes?

  Is that like they have type 2 diabetes? Or they give stress, or they have heart attacks because of obesity? Or what are those names?

• 46:06Shawn Stevenson?

  So these are comorbidities, right? So these are comorbidities.

• 46:09Lewis Howes?

  They're obese, but they die from something else.

• 46:11Shawn Stevenson?

  Right, right, but that's there.

• 46:13Lewis Howes?

  400,000 people every year?

• 46:14Shawn Stevenson?

  Every year, yeah, yeah.

• 46:16Lewis Howes?

  It's, you think if they weren't obese, that they want to die?

• 46:20Shawn Stevenson?

  The obesity is, it's kind of fueling the flames of the inflammation, for example. It's fueling the flames of the metabolic dysfunction.

• 46:29Lewis Howes?

  Right. You could still look healthy and die of a heart attack. You hear that sometimes where it's like.

• 46:35Shawn Stevenson?

  But today, it's the exception, not the rule.

• 46:37Lewis Howes?

  Right.

• 46:37Shawn Stevenson?

  The majority of the time.

• 46:38Lewis Howes?

  Right, right, right.

• 46:39Shawn Stevenson?

  It's related to being overweight and obese.

• 46:40Lewis Howes?

  It's probably with the stress or some type of like inner, you know, stress. Maybe you don't look unhealthy, but inside you're not able to deal with anger or resentment or stress or shame, or whatever it is.

• 46:51Shawn Stevenson?

  Your thoughts are creating chemistry in your body.

• 46:53Lewis Howes?

  Man, crazy, isn't it?

• 46:55Shawn Stevenson?

  It is, it's powerful, man, it's powerful. But you know, this really ties in well with this topic of cognitive function.

• 47:03Lewis Howes?

  Yes.

• 47:04Shawn Stevenson?

  Because we talked about neuroinflammation, but specifically the research was indicating hypothalamic inflammation. So that's inflammation. The hypothalamus is, it, it's really been considered the master gland of the, of the human body.

• 47:18Lewis Howes?

  Where is it?

• 47:19Shawn Stevenson?

  So it's in your brain.

• 47:20Lewis Howes?

  Okay.

  It's, it's, it's in your brain, but. It's so I think the best description is the hypothalamic pituitary adrenal axis. So we've got this HPA axis and there's so many other glands upon that axis, even the thyroid. And so the hypothalamus is kind of like in the boss's office in a sense, right? But I would argue that it's not necessarily the boss because everything is working together. But the reason that it's considered a master gland is that the hypothalamus integrates your endocrine system, the production of all your hormones with your nervous system, which is like sensing your environment, your internal, external environment, based on that data and that feedback, integrating the two. And your hypothalamus is also controlling even calorie absorption.

  It's in constant contact with your gut. And so the vagus nerve is linked up here as well. And so based on your assessment, your brain's assessment and also your gut of your caloric needs, how much energy you have stored, your, your brain could tell your gut to increase the absorption of calories from the food or decrease the absorption of calories from food. And so we talked about this last time about these.

• 48:27Lewis Howes?

  Your brain can tell your gut, when I'm eating all these calories, don't absorb these calories, just let them go out.

• 48:34Shawn Stevenson?

  Yeah. Essentially. It can down, it can down regulate it. But it's not going to be like you can just eat a donut and you don't absorb anything. You know what I mean?

• 48:41Lewis Howes?

  That'd be amazing. Could your mind actually do that though? Do you think the mind could control and say, I'm going to have 1500 calories right now with this ice cream and donuts and nothing is going to be absorbed in my body. It's going to go out to me and you just manifest, you just decide and declare, no. Oh, such a powerful first part of the conversation. And we're going to end that first part right there.

  Oh, that is the truth sadly, and it's unfortunate that there's too much suffering and pain happening in the world. A lot of it is due based on our choices of what we eat, how we sleep, how we think and feel about ourselves, and many other things as well, but food and nutrition heals my friends. I hope you're doing your best to make the best choices. We're all human beings, you know, I'm a guy that loves to have some candy, some cakes, some cookies every now and then. But if you can do your best, I'm telling you, have some quality meals throughout your week. That will help you improve the quality of your health. It will improve the quality of your life. And I want to remind you, if no one's told you lately, that you are loved, you are worthy, and you matter. I'm so grateful for you, and you know what time it is. It's time to go out there and do something great.
