In short

Insulin sensitivity as a driver of muscle gain, fat loss, cravings, executive function, and long-term metabolic/vascular health; how CGMs plus behavioral coaching reveal individual glucose responses and stress effects.

Guest

Dr. Rhett Langley, Houston-based Thrive Medicine clinician specializing in metabolic and sexual health; traditionally trained/boarded in anesthesia and pain medicine; spent ~7 years learning “how to make people well.”

Key claims

Metabolic dysfunction starts with impaired glucose/fat physiology and cascades into cardiovascular disease, brain issues, and sexual dysfunction. Exercise and diet improve metabolic health, but behavioral modification is the main lever; CGMs help contextualize glucose variability and improve adherence over 300–600 days. Sleep regularity, resistance training (muscle as a glucose “sink” and neuroendocrine organ), and stress reduction stabilize glucose.

Notable examples

A prediabetic client’s glucose spiked after a hard leg workout, attributed to stress/liver glucose release; “carnivore” expectations of flat glucose failed on CGM, showing protein still triggers insulin response and variability. GLP-1s framed as “chemical bootcamp” that reduces appetite and improves insulin sensitivity beyond weight loss. Sexual dysfunction described as largely vascular; ~25% general men, ~50% with metabolic risk, and ~43% women with sexual dysfunction; structured behavioral programs (Look AHEAD) linked to remission.

Head on over to mindpumpstore.com. That's it. Enjoy the rest of the show. Welcome to the show, Rhett. Thanks for having me. Yeah, so tell us a little bit about what you do, your background, so the audience can kind of know where you're coming from. Yeah, so primarily I run a clinic in Houston, Texas.

3:04It's called Thrive Medicine. And we specialize in metabolic health, sexual health. You know, I'm boarded in anesthesia and pain medicine. That's my traditional training. Okay. And then I spent the last seven years after doctor training really learning how to actually make people well. Explain metabolic health and what that – because you hear that a lot now. Like this is like a big thing now in medicine or in treatment or in the wellness space. What is that exactly? Yeah. So when you go on this crusade to try to help people and you look at, let's just say, this large list of symptoms that people have, whether it's – You know, and I break it down into like two large factions.

3:48There's sick people and there's people with problems that may not be determined as sick by the medical community. Right. So sick people could be like, hey, I have cancer, dementia, sexual dysfunction, cardiovascular disease. And then over here is this, you know, esoteric, not otherwise specified, I have fatigue, brain fog. I have, you know, skin inflammation, sleep disorder, et cetera. mood lability. When you look at all of that stuff, the really at the bottom of that rabbit hole is the, is the term metabolic dysfunction, right? And real simple definition of that is the physio, the physiologic processes in the body are not functioning properly, right?

4:36And it starts with looking at glucose, looking at fat, and then that translates into worse things like cardiovascular cardiovascular disease and like we said sexual dysfunction issues with the brain so on and so forth so okay so it's essentially the you're looking at taking um what you consume and turning it into energy in that process although i just simplified it it's a very like the like complex process we're talking about the metabolism there's a lot of things that are happening yeah yeah okay yeah i mean if i said to you like hey food is fuel you'd say okay cool podcast bro great but But essentially, you know, that's what it is.

5:17We're talking about like exchanging oxygen to CO2, taking in stuff, having your body utilize that appropriately and making sure that that physiologic process is dialed in. How much can this really affect someone's ability to build muscle or burn body fat officially? I mean, in our experience training tons of people, I've experienced this where, you know, you know, you've got them on a good diet, you're exercising correctly, and then their body's just not responding and it's not adding up. And many times there's other root causes. So like how significantly can it impact that ability to build muscle or burn body fat?

6:00Yeah, I think it's a huge impact, right? So it has a very, very large impact. And honestly, bodybuilders get this, right? They utilize insulin also to put on muscle, right? And they also know, like I even saw, of course the algorithm has control of me, but I saw the other day one guy was touting, he's like, hey, if you're fat already or if you can't see your abs, don't try to put on muscle. So they're already catching on to the fact that it's not just calories in, calories out. You know, how much we eat and what we eat is really, really important. But when we look at what's going on underneath the surface, it has a huge effect on our performance, whether we're putting on holding on to fat or adding that to muscle.

6:43And then all the other problems that come from that process not being dialed in. Now, doesn't exercise applied appropriately and diet improve the metabolic health of somebody? Like those are also methods that can help with that, right? Yeah, a thousand percent. I mean, even so I would say like that's hate to get to the point, but that's the overarching theme, right? Lifestyle modification. And if you look at, so you're going to hear me talk about these studies a lot, but some of the really, really large behavioral modification studies, one of them was diabetes prevention program, the look ahead trial, those were behavioral modification.

7:24Those studies were RCTs, right? And we're talking 5 ,000 people showing that behavioral modification most likely beat out other interventions. And what was that? It was looking at calorie intake, looking at physical activity. And then the other major thing here, the major thing, especially when we're talking about CGMs or what we do in our clinic, is they had a structured program. So they put these people through a structured program. right? You just can't give someone data or tell them like, Hey, eat more, move less. Like, cool. You have to spend time with these people and teach them and, uh, you know, modify that as you go along.

8:05So what made you move from, so you, were you an anesthesiologist or trained as one? Did you practice? No, yeah, yeah. No. I mean, I, I still do some anesthesia. Okay. So what made you move from there to, to this space? It was so different, uh, uh, in the sense that like, you know, in anesthesia uh you're you know you're titrating people's um anesthesia making sure everything's okay during surgery that's what you do now you're like cool let's look at your whole life yeah let's look at your lifestyle let's look at your diet like what made you move into that space was there something that happened oftentimes i talk to doctors who do that it's like they either had their own health issue or a family health right was something like that yeah i mean you know to answer the question first and then back up and tell the story it was subtle and i think people relate to this i thought i was healthy and felt bad and didn't know that right and you know maybe you guys can relate i was like i was 90s fit bro right so i was this was prior to my awakening where i thought i was doing a bunch of stuff i was going to the gym twice a day you know and back in the day maybe you can relate it was you know explode muscle milk good time cell tech yeah we're the same age i'm dating myself we're all the same age uh you know men's health magazine was my bible and you know at that time don't judge me this was like dial up so checking the sources was not a thing right so if men's health told me like hey tequila tequila stimulates metabolism like all right cool like let's go right um you know calming your nervous system or mental fitness was two drinks, lie in bed, negative feedback loop, right?

9:48Like you suck, bro. That's how I was taught. That's how we grew up. Um, and then, you know, choosing the wrong relationships, right? So it wasn't until, and again, you know, let's just, I'll stop joking just for a second. So going through doctor school and doctors get hazed a lot, a lot about like, Oh, it's not appropriate training or that's out of context. And I will totally say on this podcast that there's an indoctrination in every professional school, right? However, doctor school broke my ass to be a really, really bad-ass doctor, right? Like it will turn you into a warrior. And when you do procedural medicine, like anesthesia, you have to, you do one, you suck, you do 10 ,000, you're bad-ass, right?

10:34I don't say that arrogantly, but, you know, back to the story, Like when I met my wife, she was like, hey, you know, are those dark circles under your eyes? Is that like a birthmark? And I was like, no, that's probably something else that's really, really bad, right? I was irritable, moody. And because of doctor school, like I knew how to sleep four hours and get it all done, right? Drink late at night to help myself go to sleep, wake up at six, I can handle it all, right? So that was just a wake-up call, right? I was like, okay, I feel good. but something else is going on. I was hitting the gym twice a day and I was puffy fit.

11:12You guys probably can relate to that too. I was like puffy fit, right? And so I knew how to do something. I was like, okay, well, this isn't working. Sarah, my wife kind of jolted me into action. Like, hey, you don't look good either. I was like, well, I don't know. I'm hitting the gym twice a day. It's great. And I realized all my other friends who were doctors also had no idea how to take care of themselves, right? So to put it back into context with doctor school. Like, you know, if your arm fell off, I was your guy. You know, if you got impaled by a fence, I'm your guy, right? If you have an anaphylactic reaction, I can help you fatigue.

11:48My penis doesn't work. You know, Hey, my, I have some skin inflammation and brain fog. No idea. So that kind of took me on the course of like, okay, well, we need to figure this out, right? I've got to do something different because I spent all of my life trying to become this thing. And we need great doctors and I can save a life for sure. But can I save a life on the other end? What I really appreciate when doctors move into the space, because you guys have some of the best training I've ever seen on how to go through and decipher through studies, data, how this you're trained that way, you're trained to look at things in that way.

12:26And so when you get pointed in the right direction, some of the best in my experience, working with doctors doing what you do, some of the best results happen because you've got that training. What was the first place you looked or what were the first things you did for yourself to kind of move things in a different direction? Yeah, for me, it was, you know, just personal, it was sleep, right? So sleep is a superpower. I thought that five hours of sleep was just what we did. yep right and honestly um after i decided like hey this is something i need to work in or at least give myself a sleep window like it's all of a sudden like my brain woke up um but the other thing that i started looking into is like okay well what am i eating you know who are the people in my life all of the things that seem really really basic you know if i said them on the podcast we're like yeah of course like that's how you fix yourself but you have to understand And apply into your life and then do it over a long period of time.

13:32So at the time when I was in this period of discovery, I was literally just looking at stuff and then I would dive right in. That's how I got connected to Nutrisense. If you really want me to tell that story, at the time Nutrisense was new. And now that I'm even telling the story, it was really new because I was like, hey, what are these CGMs? And in fact, full disclosure, I was like metabolic dysfunction was not taught to me in medical school, that term. and I don't even know. I mean, I've been through a lot of stuff, even war. So I'm not sure if even someone even said it. But at the time that I was trying to get healthy, it had just started to become popular, at least in my world.

14:09And so I was like, okay, well, you know, what is this CGM? You know, what is this company Nutrisense? So I called the company. Oh, so you called them. I called them. Oh, wow. And that's how I did everything else. I mean, that's how I learned about peptides and that's how I learned about, I would just find something and call the person. And at the time it was new. So usually I would get the person on the phone. So when I called NutriSense, I was like, hey, I'm interested. I'm a doctor. And this guy Dan jumped on. He talks faster than I do. And so he's like, yeah, I own the company. I was like, well, where do I get more information?

14:42He's like, I own the company. Ask me. He's like, did you not hear what I said? So anyways, that's how, and again, that's how I learned. I would just find something that I was interested in, figure out if it was going to have an impact in health and then just dove right in. Well, tell me more about that process with Dan and like asking him. So you get him, you start asking questions. Are you instantly like, Oh, I believe in this. Or it's like, what starts, what piques your interest in it? Do you order one and start testing it yourself? Like, tell me about the evolution of that and how that unfolds for you.

15:17Yeah. Well, even that first conversation was like an hour of conversation. I was just talking about, you know whatever business life and how the cgm impacts people's lives and you know i'm gonna be honest when it first came out there was a lot of heat like oh yeah it's just a gimmick and blah blah blah yep so of course i was also trying to start my clinic and mind you this was i don't know it was it was late 2019 and like right before covid hit so there's a lot of other stuff going on but I started uh I was like okay let me order a few of these I had a few clients right and I was like oh this is it I'm gonna put everybody on the CGM we're gonna start learning about metabolic health and by the way I'm also gonna learn about metabolic health right so I started trying it um and the app was new but the biggest difference even for me and I'll I have no problem saying this as a doctor as i was learning as i went but also talking with the dietitians right and so and at the time my wife was my wife's a dietitian so she was in her residency finishing dietetics so just even getting on the even getting on the uh a call or a zoom with these dietitians and i was i was special i was like hey hey i want to talk to your dietitians i was constantly wanting to talk to these people like teach me teach me what do you do here what do you do here what do you do period of discovery and i could tell that that this was a different tool because it was helping me understand how to change my behavior yeah right so i love like some there's been some cool cgm stories like or cg when you do you remember the first like aha or like well that's weird because i've seen times where you see somebody who one person eats a food and they react a certain way and then another person eats that food reacts completely different.

17:08Do you remember the first time you had kind of like that for yourself or for a client? Yeah, absolutely. And again, like I said, we're just going to get raw on this podcast. Around the time it was carnivore was really, really popular, right? So, of course, I'm trying to learn. I'm like, oh, carnivore, this has to be it. Let's try this.

17:29Rhett Langley:And it was the same time that I was doing the CGM. so you're eating just me and you put on a glucose monitor yeah and you're expecting zero zero spikes yeah but i mean even me like it's you know my wife knows how extreme i am i'm like i'm gonna be flat dude i'm just trying we want no glucose spikes right let's be as flat as can we pause for a second your wife's in in residency as a dietician and she knows you're just gonna eat me was there like what was that like at home i am dying because when she hears this she's gonna be like he knows because i would be like no no nope that's it i would hear something be like that's it plants are gonna kill you she's like you're dumb i'm not doing any plants she's like dumb and of course it's fine for me telling that because you have to you have to do this stuff yeah to figure it out right yeah so yes i went through a carnivore phase and i was like yeah that was dumb um but no yeah she i mean but the expectation is i i'm eating no glucose i'm having no carbs no sugars yeah yeah no fiber right and so i should have flat yeah what do you actually see though yeah well what you see is in the longer again you know i don't recommend carnivore the longer you take it out the more variability potentially you have right right so even eating protein you're gonna have an insulin response that's right And so, of course, think about me.

18:58I'm trying to teach people and learn, and I'm like, okay, this is not making sense. Maybe I should eat some plants. And she's like, yeah, you're dumb. Yeah. So explain – because my favorite aspect of CGMs, and now that they're more popular, is just something that we noticed as trainers. Now, I couldn't give you a blood marker or measurement, but I just trained enough people to know everybody responds different. It's really weird. She could eat this in the morning, and then this guy eats the same thing, and it's appropriate calories. Macros are appropriate, but he just feels like crap when he eats the same thing that she does.

19:38And you just see this enough times as a trainer to go, there's a big individual variance. I can't explain it. I didn't even know how to explain it back then. but then you get cgms that confirm oh yeah like this guy eats a potato she eats a potato he has a crazy response she seems to be okay explain why do we think that happens like what's going on there yeah i mean when you look at variability and you know when i'm working with clients the number one thing people do is they say okay well i had a potato and then i have this response or let's say they have a response like oh yeah it was definitely the potato and i was like well let's think about it let's look at all these data points because you're a human you have a you know complex complex question complex answer right so instead of just saying like hey you had the potato let's look at what happened the last five days was your sleep bad did you get in a couple of arguments with your significant other how was your hydration did you work out that day right so even looking at lifestyle and also looking at the physiology of the human right yeah how much fat are you carrying right um what what else are you eating with the potato around the time with the potato so it it helps us kind of decipher what what else it's as individualized as it can get and even more importantly than i think the bigger conversation here is that i remember unlocking this with clients was because one might say well who cares who cares if it's got this risk who cares yeah it gets a little bit if it's the same amount of calories and i stay within my calories but what I started to connect the dots to is when you see that how difficult it is for the client to fight off cravings and other things when when you see these huge swings and that to me is the important conversation is that you know because that's where someone well if I just follow the calories who cares if these foods make me go up or down but when you talk about behavior modification and how important that is in this whole process if you didn't realize it that you have this reaction to a certain food, it makes it that much more difficult for you to stay on track.

21:45So talk a little bit about that, because I think that's the bigger conversation more so than the variability of a client spiking or not spike. Yeah. Yeah, absolutely. I think honestly that that's the take home message is when you are a good practitioner or trainer or doctor or whatever, if you want to make an impact in someone's life, it's going to be behavioral modification. And there's randomized control trials that show that, right? So it's easy for me. This is an amazing tool because when someone looks at a glucose spike and they say, who cares for me, I can put it in context. I can say, okay, well, you know, you're a busy executive and we know that glucose variability is going to have an impact on a cognitive function or executive function, right?

22:29When someone, when a client comes to me and they're like, Hey, uh, when I say, okay, what are your goals. They go, I want to feel better. And I'm like, okay, well, when you unpack that, yeah, it's, it's mental resiliency. So cool. Like you want to feel better in your body or no, you want to be James Bond, right? I want to, I want to make a decision and then have a plan to kill everybody in the room. Right. So, so that's executive function. If I said, Hey, who cares? But also when, when you're having all these spikes all day, it's going to lower, it's going to lower your executive function, your ability to make decisions, right?

23:01The highest form of thinking is thinking about what you're thinking. Yeah. Metacognition. Yeah. So it puts it in a different context for that client and hopefully, and again, you have to work on that over time. So not just like having one instance with the client, let's work it, work on it over 300 days or 600 days, right? How hard or easy was this transition for you? Because, um, coming from with someone who's a doctor. So you're one of these, you're probably the kind of guy that's like, I'm going to make a change. I'm just going to do it. I'm just going to decide. I'm just going to do it. Then you also work in the medical system, which is like, you know, you show up, someone has something wrong, do this, do that, and you're gone.

23:42Now you're working with people on behavior change. Do you ever get frustrated? Because it's really hard to change behaviors. Yeah. Yeah. I mean, what I would say is it wasn't as hard for me because that's what I like to do, right? I mean, I was in the military. So if you tell me like, hey, you suck, do more. I'm like, okay, sir, yes, sir. Like, cool. That's how I respond, right? I want someone to tell me. And again, you know, your circle is the collection of, you are the collection of the five people you hang out with, right? So, and in fact, that's where I shine. And everybody at the end of the day, the best doctors, they become a coach.

24:18The good ones become a life coach on top of taking the data, on top of prescribing the medicine, right? You sit down with the patient and you over and over again. But it was awesome perspective because I would go over here and try to make someone well, right? And train them on doing X, Y, Z and then go over here to conventional medicine where people are dying. And yes, save some lives. But having that dichotomy helped me understand like, hey, if you don't change, you're going to get to this side of the spectrum. I had some really interesting experiences early on as a trainer that really just defied my knowledge of blood sugar and all that stuff.

24:55Just because, you know, I understood very basic things. But I remember once I had a client who was pre-diabetic, so we had to test his blood sugar often. And I'll never forget, we had a really hard leg workout. And his diet at this point was good because he was trying to get out of pre-diabetic stage. And he went home and he calls me up and says, dude, my blood sugar is through the roof. I'm like, we just worked out. That doesn't make any sense. It was the first time I understood how stress could cause a dramatic rise, just cause your liver to dump a bunch of glucose in your system. I remember when I first got that call, I said, I can't be right.

25:28Test yourself again. He's like, no, dude, it's real high. And I'm like, uh-oh, what did we do wrong? And I just had no idea that stress could cause that. Yeah, yeah. That's actually one of my platforms. It's like 2026, right? You can't just be a husband. You can't be a father and have a nine-to-five. you got to now have a five to nine like a 10 to two you got to know how to day trade crypto so like all day we are literally in fight or flight okay so and everyone understands like that there's a reason there is a reason physiological reason for that right blue light hits your eyes cortisol rises you wake up and you hunt or gather right again that's a simplistic term it gets towards the night lowers you go to bed staying in that all day is a problem and and teaching clients that like hey i can make your labs look beautiful we can make your body composition look beautiful and also i would argue that that's going to help you be more resilient but if you if you stay in this uh high nervous system activity state it is going to kill you um and we even see that in in glucose right one of the interesting studies that i like to talk about with the clients it's like you might not see even with stress you might not see that cortisol effect with fasting glucose and when you go to a conventional doctor's office they're going to check a fasting glucose right but we do see it in postprandial so we see it after you eat and i always reference this one study where they're they artificially created like a stress test it was like a social stress test because this is straight nightmare feel and i'm saying this as i'm sitting in front of three people but they would have you eat.

27:08So you eat your oatmeal and then within the hour, you immediately go to another room and you have a mock panel job interview. And so then they would measure like the glucose, right? Or the other option is you would eat and then you would go into a live audience and do math equations, right? If you messed up, you had to start over. So, I mean, and think about that, right? You might have, again, you got to close deals, right? It's business, but you're having your meal in a high stress situation, not to mention all the other other stuff that we have to deal with in today's world and i always tell clients i'm like you get what you practice and i'm not immune to this stuff right my my wife the best thing she ever said to me was uh you love putting yourself in a constant state of shitting your pants and i was like thank you it's like despite your best efforts that's something really cool you know i'm not immune to this stuff like we i deal with stress all the time I'm a business owner, it is like this all day.

28:05And then we're expected to come home and lower our nervous system, but that's slowly killing you. Right. And so the CGM is a good way to show people like, Hey, if you do this, this is not good. So we need to do something to help along those lines. What are some of the practices you've, you've applied with, with clients to help them with that part of it? Yeah. Yeah. Yeah. Well, and, and what's interesting too, is when I I ask them like, hey, what do you do for stress? They'll say something like, okay, well, I listen to music and I'll push them a little hard. I'm like, no, no, no, which it's fine.

28:36Music helps you. But what do you do to lower your nervous system activity, lower your heart rate, lower the sympathetic activity, you know, and one of the biggest takeaways I have for stress, I learned while I was in the military, you know, I was deployed for a year in Afghanistan with special forces and you have that constant high level of stress of i don't know whatever getting getting blown up and i learned it from special forces so you know where is this coming from our limbic system right limbic system wants us to be safe routine a routine your brain notices routine as safe predictable yeah so even in even in war what do we do we clean our weapon we go get a haircut we make our beds right we prepare whatever you're the bullets right so sticking to a routine will make your brain feel safe and that's why some people think like oh well that's a very boring lifestyle but actually the brain does like routine was that strategically put in by the military for that reason oh yeah absolutely did you know that while you were going through it like were you

29:45Rhett Langley:aware of that or is this you reflecting you know no no i was like i told you i was just a fitness bro like okay cool this is what we do you know but also and i don't mean this to sound arrogant i didn't my mind was not constantly on you know whether a rocket was going to come over and hit us especially when one of them hit your friend you know um i was just it was a very peaceful time surprisingly because we had one place to eat one place to get a haircut there was also just one haircut you didn't have to tell them what haircut one place to work out uh you know and one job to do. Yeah. So that routine, you know, I would go as far as to say there's times where I'm experiencing more stress in this chaotic environment than I did on deployment.

30:27Interesting. What are some of the practices that you've noticed that have the biggest impact on somebody's measurements, variability? Yeah. Is it exercise? If so, what type of exercise? Is it the diet? Probably sleep routine. Sleep. Like what are the ones that you notice most? Yeah. I mean, the obvious ones are sleep. You know, sleep is a superpower. We've, I think you guys have talked about the studies on those, but even if you look at studies on sleep, independent of obesity, having a regular sleep schedule is going to make your, your glucose more stable, right? Going to bed at the same time.

31:07That's another one I had to learn, right? Because I don't know what you guys, and my wife's probably going to kill me, but she goes to bed late. I go to bed. I'm grandpa Langley, right? I try to go to bed between 9 and 10. She's more after midnight. And so, of course, I want to spend time with her. When that – even if I get an eight-hour window and I try to go to bed at midnight or 1, I feel like shit the next day.

31:27Rhett Langley:Yeah. Right? You jet-lag yourself. Yeah. I mean, obviously, body composition. So what I tell my clients, I understand when they leave the clinic, you know, our overlords have set up a system that's going to attack you, right? toxic people, toxic water, toxic air, toxic foods, etc. So we work on making the body more resilient. And that's lean mass to fat mass. So obviously the lever there is resistance training. Yes, you should do some cardio, but trying to get that fat level down, right? Change of body composition. I love, you know, years ago I did research on insulin sensitivity and how exercise, different modes of exercise affect insulin sensitivity.

Read the full transcript

32:13and now this is what I thought I would see, but to see the studies back it up and just how much, it was pretty cool to see that strength training of all the forms of extra, you know, it doesn't burn a ton of, a traditional strength training doesn't burn a ton of calories. You'll burn way more calories doing Zumba or running than you will lifting weights for the same time. But the insulin sensitivity was like, and gaining lean body mass was huge. I remember reading one study with obese individuals who lost no weight. They just gained a little bit of muscle and they saw these huge improvements in insulin sensitivity.

32:45What's happening there? Why is it such a big game changer? Why is it not just burn calories? What is it about building muscle that does this? Yeah, so if you look at those studies, I think it was for every 4 % in lean mass, it was a 4 % decrease in hemoglobin A1C, which is obviously a conventional test they use to detect blood sugar, then 6 % decrease in fasting glucose. but the idea is that muscle is your biggest sink for glucose, right? So 80 % of the glucose that's circulating is going to go into muscle and be stored as glycogen or be utilized, right? So that's step one. And then also muscle is a neuroendocrine organ.

33:24So it's going to also secrete myokines that would assist with not only brain power, right, allowing you to make better decisions, but also just make you feel better in general. Yeah. There was one study I read out of, I want to say it was Australia, where they were looking at the impact of exercise on Alzheimer's. And they were looking at the beta amyloid plaque. Yep. And that strength training was the only intervention they found to halt the progression and might have even looked like it was starting to reverse. And they compared it to other forms of exercise. And my theory is it had to do with the insulin sensitivity because cognitive decline, Alzheimer's, dementia, some researchers would call it type 3 diabetes.

34:08So talk about the brain health benefits of having improved sensitivity to insulin. Yeah, a thousand percent. We just talked about more time above range or let's say glucose variability, less executive functioning. But when you take that out over time, obviously Alzheimer's and or dementia has a metabolic component. And the other thing, other association I'll make is when you have metabolic disease, you have vascular disease. So one of the issues with the brain is highly sensitive to changes in energy, right? Glucose requires a lot of energy, right? I think they're clocking the optic nerve as one of the levels that requires the most oxygen.

34:54So requires a lot of oxygen and energy, glucose, very sensitive. If you look at people who have insulin resistance, you're going to increase your risk of dementia by almost 70%. And then vascular dementia is higher than that. Right. And for me, you know, this is my personal sentiment. But if you look at all these problems that humans have, one component is always going to be blood flow. Right. That's how the body talks. That's how it brings in oxygen. That's how it brings in nutrients. and that's how it takes out toxins you know so dementia is on the rise alzheimer's on the the rise and that pathophysiology is very very very similar the whole point of this talk is like how can i take a look at someone who's sick and try to not do stuff to get to that point right so someone who has dementia i mean that there's nothing worse than losing your mind especially if you're able-bodied so those are very very very um those correlate strongly i always found it interesting when people would debate or question whether or not cognitive decline was a result of metabolic dysfunction.

36:03When we've had studies, we've known this for a long time, that if you put a person with Alzheimer's or dementia on a ketogenic diet, we see improvements in cognitive function. Not that that's a cure, but obviously something's going on there because we're switching energy sources and suddenly their scores move in the opposite direction of where they've been moving for the last 10 years. So to me, that seems like a very obvious, like there's something metabolically going on here. Yeah. And you see how also the, how sensitive the brain is to neuroinflammation, right? Yeah. So when you have impaired glucose, you have impaired fat deposition and that, those, that sugar that's circulating around the brain is going to cause inflammatory products.

36:44And you can even have acute cognitive changes, you know, the sugar's high. Well, I'm curious to ask you about with the rise of GLP ones and like what you found, you know, in your own practice or if you prescribe or, you know, if you've combined that with these glucose monitors and like what kind of data and results you've seen from that. Yeah, I, you know, when something gains popularity, we all win because we everyone starts using, especially if they can make money on it off of it. right? Then we all get all these studies and we see how safe it is and all the other stuff it can do. We use GLP ones and I was using GLP ones for a long time before it kind of got popular.

37:26And so I love them. I think they have profoundly positive effects and I'll tell you the context of how you need to use them, but it does two things. And I talked about those behavioral studies where people were watching what they ate and they had a structured program. So the way I look at GLP ones is it is chemical bootcamp, right? So when you put this in your body, it's going to be really hard. And I'll tell the clients like, it is really hard to eat poorly because you get really sick, right? That's what I've seen in my clinic. Right. And what do I mean? Well, if you have two glasses of wine and a piece of pizza and some ice cream, you're going to have a bad night.

38:04And so it becomes chemical bootcamp, right? So even if I can't be with them there all the whole time and I'll even tell them, I'm like, Hey, you're going to get sick. Not that I want you to get sick but you won't do it again right and so that medication has really really two been two large benefits one it's going to lower appetite and lower gastric emptying so people are going to eat less caloric restriction and then boom it's going to fix insulin sensitivity or let's say enhance insulin sensitivity and so you even see like the fda has now approved it for cardiovascular risk Right. Less hospital admissions, lower cardiovascular events, and then even kidney protection.

38:48So chronic kidney disease they're using. It's FDA approved. And kidney disease is a vascular disease. Right. Those go hand in hand. Are we seeing improvements in insulin sensitivity from GLP-1s independent of the weight loss? like are you like if someone has a cgm using glp1 before they lose weight how do you tease that out

39:11Rhett Langley:you'd see it right away i guess you would use it and you'd see well essentially you also yeah you can see that away right away in the cgm but they have studied the medication they know the mechanism of action right so even before we're again remember they're using this in diabetics before it got popular 20 plus years right so we already know that the it makes the periphery more sensitive to insulin or improves glucose control within the body. So side question, maybe you don't know the answer to this, but I'm now seeing a lot of talk around PDE5 inhibitors like Cialis, not for what you typically would be prescribed for, which is erectile dysfunction, but for longevity.

39:52They're showing now that there's reductions in stroke and heart disease. Do you see any different, when people use a CGM, do you see an improvement in insulin response or blood sugar response? from sal are you asking me for a script of no just subtle way of asking just kidding yeah and and honestly that's how we use it too and you know a lot of guys in the gym use it for yeah performance right they've been doing that since we were all kids whether that helps for performance or not that's what they're using it for so and i can easily relate this to stuff that kills you so the end product of phosphodiesterase inhibitor is nitric oxide right nitric oxide your body makes nitric oxide and you need nitric oxide for auto regulation, which is just a fancy term for the blood vessels, relaxing and squeezing in relation to the amount of oxygen you need.

40:43Right. So yeah, absolutely. Like we're, they're using it on the regular to improve blood flow. And as I told you, like for me, the whole discovery of me becoming this wellness doctor is realizing like I'm a blood flow doctor when organs died is blood flow. And that's what people die of it's cardiovascular heart attack and stroke right you don't die of diabetes it's the same thing with sexual dysfunction right the same vessels in your penis or vagina are the same vessels in your heart and they work the same way yeah and so we see if somebody uses a pd5 inhibitor do we automatically are you seeing immediate like changes in their cgm readings is it or is it showing up in that way or does it take longer yeah the the context that yeah the context for me is more of uh blood flow okay right so it's more of improving blood flow to organs sure right okay yeah it exercises the essentially the vascular system relaxing contracting yeah and also when you have uh metabolic dysfunction the biggest issue is vascular dysfunction right vascular inflammation right that process that cascade of you've heard that that term or i've heard a couple of people say like the difference between a sick person and a healthy person is a teaspoon of sugar in your blood yeah the major insult is insult to the endothelium the inner that glycocalyx that slimy layer of the vessel right and you know even if you look at let's just talk about like sexual dysfunction in men um across the general population it's like 25 percent which i think is still kind of ridiculous right that's one in four yeah when you look at someone with metabolic resistance that jumps to like 50 it's like half so clearly that's a vascular issue clearly heart attack and stroke is a vascular issue right that's the problem so and when you have hyper or diabetes you have high blood pressure right the diabetes is causing the high blood pressure what what percentage of your clients that you're helping uh battle with sexual dysfunction i mean anecdotally like in my opinion it's an epidemic it's a lot i mean probably half of my clinic is sexual dysfunction and this is also this is also jaw-dropping this is this is this is gonna rock your world like the people with metabolic risk or excuse me when you have obesity up to a 13-fold increase in hypogonadism.

43:15And I'm not saying sexual dysfunction is just testosterone. It's blood flow. It's multifactorial. It's all connected. Yeah. If a guy comes to me and he's like, hey, I hate my wife and she insults me and I don't get an erection, I'm not going to say, hey, it's your metabolic health, right? Our brain is our biggest sexual organ. So we're going to impact that a little bit. But I'm going to say like, hey, let's look at some labs. Let's check the physiology. But I think it is an epidemic. Like it is not only on the rise, but it's ridiculous. And the other thing I'll talk about real quick is women. The, and this, this shocked me.

43:51The percentage of women across the population that have sexual dysfunction is 43%.

43:56Rhett Langley:General population. Yeah. So that. How do they measure sexual dysfunction for women? Cause you're not measuring your, you know, erectile. Yeah. Yeah. And that's a good question because yeah, that's a good question because passive pathophysiology is the same. It's still blood flow to the sexual organs. And so desire, dryness, pain, right? Libido, orgasm, right? And one interesting connection I will make from that, the behavioral modification, the look-ahead trial, such a prolific trial that they had these spinoff studies and one of them was women's sexual dysfunction. and so in that trial of the people who had metabolic resistance or had obesity 50 had sexual dysfunction with the modification or the structured program 30 went into remission so again you know that statistic is shocking 43 it's higher with people in women but it's you know we see a man we're like okay i can't get an erection it's obviously a vascular issue right Right.

45:01Rhett Langley:But women struggle with this too. Interesting. How, how are CGMs being used now for behavioral modification? Because CGMs measure your glucose in real time. How do you combine that with, uh, coaching or, you know, behavior to like, what are you looking at and how are you using that as a tool to help somebody? I'd like you to take me through a week one. I just signed up with you. I've got metabolic dysfunction. Yeah. What do you, do you just let me eat what I normally eat and monitor me first do you give me stuff like tell me what a week looks like when we get together yeah well i also you know get an opera out of the out of the clinic too so i have the benefit of taking comprehensive labs so we it's even even more interesting when i can show them the labs and then show them the cgm which is this beat to beat look at their glucose and then give them the context of like hey if you don't do this these are the problems but week one is really just what I want to do is I want to get their baseline.

46:01Right. So do your thing. I'm like, don't, because you know what people do. You guys are in the space, right? You know, and even when you ask that, you know, the 90 % clean bros, right? I eat 90 % clean, right? I'm like, okay, well, let's like test it. And that's also like the biggest takeaway is I get clowned sometimes by clients. I'm like, hey, you should, you should fit. How's your sleep? Oh, sleep hygiene. They're like, yeah, don't even go. I know that. I do it. I'm like, okay, well, let's unpack that. Well, there's eight or nine steps to sleep hygiene. What you find out is they're maybe doing two, 40 % of the time and three, 10 % of the time.

46:36Right. It's the same thing with all of the other lifestyle modifications. They're doing some of it, not all the time. So week one, I'm like, don't change anything. And they still will. Right. I actually have to make it a point to like, listen, if you ever occasionally have a Snickers that have that. I want you to do that thing. You got to be, give me a week. And that's also the problem with other companies that don't have that one-on-one dietician contact or even in my clinic. If someone puts something, just the bias of checking, you're going to be living a lot better than you normally do. Right?

47:12So you're going to be like, oh, I'm good. Just be perfect. Take this thing off and go back to what I'm doing. Yeah. And so that's what I told you. The biggest impact is this stuff is, if I told you, hey, hey, move more, eat less. You're like, cool podcast, bro. But you need to do that over a long period of time. All of these little nuances to add up. Have you gotten to the place where the more you look at the stuff, because I'm sure you get some of this pushback, like I get a plan, my sleep, I got to do all these steps. I got to look at this, that, the other. Have you gotten to the place where you're like, well, I think the world is just designed to make us really unhealthy.

47:49So that's why we have to do all this stuff. because we weren't really supposed to wait though i want to i want to because i know it doesn't end where take me step by because it links to what you're going where you're going right now like okay so the client here's my week and i'm assuming he's got similar advice like how we take someone it's not like do all these things yeah right because i'm sure you've already learned that that doesn't work very well either when you give them the all the answers so so i do this week and you you see all this shit that jumps out at you and we and we look and so what what does it look like do you choose one big rock do you like this is the first lever we're gonna pull like how do you coach me through that after you get my shit labs and shit week that i give you because that's probably what it is for most people right let's be honest yeah well the first thing i do is set expectations and i'll even say this you know i'm giving away all my little secrets but i'll be like look you will know what i'm saying don't believe me well you'll believe it when you see it but you'll know what i'm saying is true when you feel better but i was like this is not going to change in 30 or 60 days.

48:48It may change in 300 or 400 days. And we are going to work through it step by step. Right. And I will give, you know, our slogan at Thrive is called empowering your health. So I'll tell the client, like, here's what I think the biggest levers are. And I'll give them a choice. I'm like, you should start with one of these three, but only start with one at a time. Right. Because I want you to see on the CGM, how, what impact that has or the way you feel, or, you know, your behaviors, you know, and that's also what the app will do is it gives you context. When did you eat? How are you feeling? What did you do?

49:26Who did you talk to? Right. Cause I told you people will automatically associate something. I felt like shit today. It's probably because I had the taco. I was like, well, it's probably the taco and also the stress with your, you know, friend. I don't know. Yeah. Right. You got to bring all that stuff into context. context and what i also call it is your health circle and again i am not immune to this as you say like the the overlords have us all under this distraction and things that are killing us so i'm not immune to that but when i'm feeling bad i go and data check myself and go oh you know i didn't take i didn't uh i was not on my sleep game you know or i changed my diet a little bit or something was off.

50:09And so then the client learns, put these pieces of the puzzle back into place, they start feeling better. How do you discern between what you know is the three biggest levers and then also what you've probably pieced together as the easiest for adherence? So this is something that over decades of coaching people, I sure have the math equation to get this person in the great best shape of their life. But I also know, and I know that this is the biggest lever, but I also know too, that could be a big step for a lot of people. And so sometimes I don't always advise the biggest lever or the best thing.

50:44So how do you like, first of all, give me what those kinds of levers are. And then how do you discern where you go first with a client? Is it always the same? Or is it, do you notice based off of the conversation, like this guy's going to have struggle doing that, pulling this lever? Yeah. For, well, for me, the biggest levers personally that i work with and clients are gotta be they have to be resistance training followed by food right you know and specifically let's just say that you know for me i told you it's we want to make the body resilient yeah right i want to get their body composition better to make them this well-oiled machine and go out in the world and handle toxins whatever that is so we know that that's resistance training and also probably is going to be a caloric deficit which means we got to stick with protein.

51:34I understand that that's going to overwhelm them, but I try to stick to something that's going to build trust. And generally when people start losing weight and they feel maybe they have a little bit of better, better body image so that it puts them in a positive state of mind. You know, the one of the ways the brain works is error correction. So everyone thinks like, okay, cool. Um, you know, dopamine is a reward molecule and it is, and it's all about anticipation, but it's error correction. So if you look at high performers, they're in this range where it's not too hard and not too little, right?

52:08You don't want to make it too hard or too little, just right where you make a mistake, fix it, and the CGM can show you. Yeah. Like, hey, you did great all week. And then Friday, you just, I don't know, you shit the bed and then boom, you feel bad. Correct and get bad. You get dopamine in your brain. So that's how you actually rewrite your brain. It's so cool to hear you answer that in that way, coming from your profession and your angle, because I feel like although we're in similar fields, we come at it at different angles. And those are the first two things that we tell people. And it's, can I get them to the gym once or twice a week, full body, strength training routine?

52:46And can I get them to eat high protein? Yeah. And those two things are such big rocks and levers that it does tend to fix a lot of the other things. And if I can just get them to commit to that, then I could start to build off of that. So to hear you say that from, you know, where you're standing and all that, like, that just shows how many people you've probably helped in your career, because that's what we talk all about all the time. And people kind of mock or, you know, make fun of or scoff at that. That's like what we simplify down to. It's like, man, those are such big rocks that if someone consistently hits high protein intake.

53:22We know that it's going to naturally start to modify their cravings and their calories. And if they just do two full body workouts a week, the amount of muscle and strength that they can build and what that will do metabolically for them, strength-wise for them, and a lot of times it even improves some sleep and energy. So it's cool to hear that, that that's what you distilled it down to. Yeah. And we've got the studies to prove that, right? You know, I'll, just to follow up on that. It's cool that you said that too, because I think that having diagnostics and advanced medicine is great. It's awesome.

53:55You know, I studied in Texas Medical Center, MD Anderson, there's all this stuff, but I think what happens is we scoff at, so we have a bunch of advanced diagnostics and the treatment may still be very coarse, right? So maybe just tell the guy like the, in the bottom of the boat, like, Hey, we need more coal, you know, all right, less cool, less cool. And people look at that and they're like, that's basic, dude. Like, really, that's what's going to change. And it goes back to what I'm saying, that if you did that, and yes, I'm not saying only that, there are nuances, for a long period of time, you would win over time, metabolically, chronic illness, et cetera.

54:33What I find interesting about CGMs is that watching someone's glucose in real time, you can actually diagnose or at least it points you in a lot of different directions, not just food. For example, how many times have you seen someone's CGM spike in the middle of the night and say, oh, you might have sleep apnea. Let's look at your sleep and see if you're snoring or what the deal is. It's interesting. It points to a lot of different things because a lot of things can cause a spike.

55:01Rhett Langley:Yep, and that's the benefit of continuous data because before that. How would you know? Yeah, you wouldn't know of anything that's going on. And go ahead. How do you use this data then to coach someone? Is it questions like, hey, we're noticing this and that. What's going on? What happened at that time? Yeah. I mean, again, the platform that I like to use is let the client figure it out themselves with my guidance. Right. So it always starts with asking like, hey, you know, one, just the thought of them putting the CGM on, they start taking more data points. and you check your own health journey, like without the CGM, you're maybe not thinking about like, oh man, I feel bad.

55:41It must be, you know, again, this, you know, whatever eight in the morning, it's probably a collection of stuff. So with continuous data, we can go back and look at it. The other thing that NutriSense is doing right now is leveraging AI. So they have this Nora, right? That will put this stuff in front of your face. so again we know the best way to win with a client is touch points right you honestly just flood them with interaction and so nora will bring up trends and bring up data even data that's that looks the same across weeks or like when you're putting in inputs it'll show you outputs right so

56:23Rhett Langley:it bridges the gap between your meetings with either the physician or the dietician any supplements that actually make a difference with what you see on the CGM? Like berberine, I hear about berberine all the time. Yeah, berberine is great. There's berberine, there's alpha-lipoic acid. And you'll actually see it? You'll be able to measure it? Yeah, the difference though is that, just remember that all in context, so berberine is not instantaneous. And that's because also bioavailability. So you need to take it over a long period of time. Another one is like myo-inositol. That one's awesome. So it's also used in like PCOS.

57:00So like, you know, that's a great one. But we're just working on basic deficiencies, iron, vitamin D, magnesium, zinc. But yes, I mean, you know, again, it's complex answers complex questions, right? You got to take berberine for a long time. It's hard to just say, hey, I took berberine and then I saw the effects. Got it. What about the GMO product that Z-Biotic makes? Oh, you know, there are - You'd be a great person to ask that. Yeah, so they made a product that this bacteria is modified to convert unused sugar into fiber. Acromantia? Good question. I'm not sure. But I know that they modified the bacteria.

57:39So it's their own patented, whatever. That theoretically should make a difference, right? Because it goes from… A thousand percent. Okay. Okay. Yeah, and I mean…

57:46Rhett Langley:That would be a fun test then. Yeah. It would be cool to give you something. Yeah, yeah. And again, extend the study over time. Right. Like you got to make it almost like a cut out all the other variables, same meals, same timing, but you know, the gut also their nutrients, they do a gut microbiome test. So we're understanding that gut is very complex. It's a great way that food interacts with the world. And when the bacteria are in proper alignment, they can help your glucose. It's interesting. You brought up myo andositol because that's been promoted forever as an anti-anxiety. And I'm wondering now if the anti-anxiety, anxiety effect is from a regulating of blood sugar.

58:28Yeah. Well, and one of the things it does is it helps cellular movement. So like storage to the end of the cell, to the nucleus. So DNA basically enhances mitochondria. It's just like NAD. Anytime you enhance mitochondria, you can have lower inflammation, lower anxiety, better sleep, et cetera.

58:46Rhett Langley:Creatine. Do you recommend, so along those lines, you must recommend creatine quite a bit. Million, billion, thousand percent. It should be part of your daily stack. You even have done studies that show, so data that shows when paired with exercise can improve glucose sensitivity. And then, of course, we know now that we're stacking it for brain effect too, right? You just have to do more. I think brain absorption is a little less. So pump your dose. You brought up the alarming stat with women, the 43%. Anything else? And you're such a data-driven guy. you got all this great all this great analytics that you can go back to anything else that was alarming to you like that you've come across that like surprised you or was like man in the data yeah yeah just um yeah there's another like another one that comes to mind and it's just deals with men it's prostate so as we're aging a lot of people are having prostate issues right and i i mean again even me going up through the medical community it's like just something that old guys had right they just went to pee five times a night and so you see this so now we're also starting to learn that's also a metabolic component so the data is now showing that with insulin resistance and there may it may be a dose response so the worse it is the larger the prostate so it can increase your risk of bph hypertrophy threefold so again if you talk about the impact on a man's life sleep if i'm having to get up five get the five or six times to sleep it's going to destroy everything else right downstream effects yeah so we fix that in the clinic and it's life-changing it's something that people overlook i mean a guy will come in and be like i'm only going to pee once a night changes his life yeah wow not to mention improved blood flow and sexual functions what about um so you hear it now a lot in regards to cancer that um yeah one of the driving forces behind cancer is metabolic dysfunction um are you are you up to date with some of this research i know cancer is very complex but yeah yeah yeah no and that brings up a good point so when you talk about metabolic dysfunction everyone understands glucose but the other flip of that coin is fat deposition right so when you're when this system is impaired you have a tendency to add fat and not just fat it's bad fat ectopic fat visceral fat that's the fat that kills us and so if you look at the risk of someone having high visceral fat it increases cancer risk by 44 and i'm talking about colon cancer pancreas cancer like the stuff that can kill you right um and then the other really important statistic of just having visceral fat is increases your mortality twofold, right?

1:01:36So, so we know there's a connection between metabolic resistance and cancer. And yes, glucose has an effect, but I just want to point out that abnormal fat deposition, which is killing people, right? It's a big, big, makes you big risk factor. When you look at just studies and surveys on people that lose weight and the fail rate is so high, right? Something like 85 % or 90 % getting the weight back type of deal. Do you see greater success rates when people lose weight through using a CGM and a coach versus doing it on their own? What does that look like in comparison? Yeah. I wish I had some cool statistics on that.

1:02:18I can just tell you in reality and you guys are in the same space, right? And what I can point out is those RCTs, those really, really large trials, as I told you, of behavioral modification. What they were given was coaching. So they had behavioral groups, they were taught what macros are, or they were taught, and then they had follow-up. And even the effects of positive, you know, lower depression, lowered anxiety, and how they thought they had a lower perceived stress of sticking to a plan. so that take-home message is like cool you can get a cgm cool you know you have these companies where you can just go like hey i can order my labs it needs context yeah it needs follow-up and even like you know as a physician like i can't do do it all you know so a whole team and that's how we work in my clinic as well yeah yeah no i would have guessed that for sure just from from my experience i think uh behavior change is hard and it takes some time and you need a coach there and then you need some grace and you're going to screw up and then yeah but over time uh far better success rate tell me a little bit more about the the ai that nutrisense is is using i haven't i haven't played with that in a while and so like is it is it giving me like it starts to pick up on my patterns of like saturdays i tend to do these oh wow and does it give you like a notification or something yes yeah positive and negative kind of trends yes it puts it in your face.

1:03:47And the other thing too, is the more inputs, the more outputs, right? So if you're saying, Hey, I went to bed at this time. Hey, my day was stressful. Hey, I worked out. It's going to tell you last week you did this and this is what we saw. And so think about that when I can't sit there and harass you and it's, it's, you know, harassing you to like, think. Yeah. Well, what's so cool about that is one of the things that we talk about a lot in the show is that a lot of what you do with good coaching is really just helping clients connect the dots. Totally. You know, half the time, uh, I mean, and we're all probably all in this room guilty of this at one point in our lives, you know, eating foods that totally didn't agree with us and just thought that your stool was normal.

1:04:32That's just, you have a bad day. It was like, you know, like not going like, no, that's actually because you ate this thing. You felt that way. Also your sleep was, it's like, Like it's just, we're so, it's amazing to me how disconnected we are to how food affects us and how, and just, so a lot of it's connected to us. So now having an AI tool that's monitoring you, that's kind of giving you that feedback loop is incredible because it's like an ongoing coach who's just kind of reminding you like, because then they start to connect it. I'm sure they go like, oh shit, that's the third time that I didn't get to bed at this time.

1:05:04and I also know so one of my favorite things to talk about with uh the glucose monitors that I noticed and it was that uh poor nights of sleep the cravings on the next day yeah what like that was mind-blowing to me and literally just becoming aware of that may help me combat it in the daytime so it's just like if I knew I got up and it was like damn that was a poor night I slept I know what I was in for that day and because I was aware of that it made me it made it easier for me to resist that. It was like, why all of a sudden I'm craving this crappy food? I've been on my diet, but it's like, oh, that's right.

1:05:39I've got that bad night of sleep. I think things like that, people just don't realize how much of what's going on with their sleep and their habits are connected to all these cravings and their moods and all this stuff. And so having an AI tool that is also giving you that feedback, that's rad. Yeah, it's huge. It's just like I talked about, when something happens, you correlate it with something that day or maybe the day before what if it you know complex questions complex what if it was seven days before what if it was 15 days before so aggregating that data really expands like whoa it's very thought-provoking right yeah and even if you know so hey i had a bad night of sleep i know when i have bad night of sleep i have cravings stick to your routine right you're like i am not going to even go over there where the ice cream is or whatever it is is your weakness right How well or how quickly is NutriSense growing?

1:06:33Because they're one of the best at combining kind of coaching with monitoring. Is it a growing field in general? And how's NutriSense doing with it? Yeah, NutriSense is crushing it. I mean, I don't know of another company that utilizes coaching. And so, yeah, there are other CGM companies. But the coaching is where it's at or the one-on-one with dieticians, with experts. and so people want that right i mean i have a bunch of clients that come to me that are fallout from you know hey i got my labs no one helped me right putting it in context so nutrisense is is blowing up in that sense um and so yeah it's really exciting and then the other thing too is when as i said when something gains popularity we get to study it so hopefully the the future forward is continuing to look at this data and then trying to get real world stuff.

1:07:30For example, like they're looking at CGM and changes in arterial flow, which would lend itself to like, Hey, what, what's going to set you up for death, cardiovascular disease, right? Right now, I can't say it's a diagnostic tool, but the more data, the more we can see the whole point of the talk is how do I not end up over there? One, how do I feel better?

1:07:51Rhett Langley:And two, how do I not end up sick or dead? What do you do for NutriSense exactly or with NutriSense? Yeah. So I am, so currently I'm the medical director. Um, and you know, these CGMs are being offered commercially, but if you were to get a CGM back in the day, it would come through me. You might see my name on it. Yeah. I got a lot of phone calls in that day. Hey, Dr. Langley, I need another CGM. I was like, Oh, talk to NutriSense. Um, but yeah, no, I mean, And I work closely with the dietitians and the team at NutriSense. My clinic handles stuff, complicated situations, and much larger conglomerate of stuff, but we work hand-in-hand.

1:08:29My clinic is very much like talking to people at NutriSense. We use the dietitians at NutriSense, et cetera. How did that – I mean, you talked about how that relationship started, and you almost were like a customer first. How did that develop into the relationship you have now with them? Yeah, well, like I said, and Dan's probably going to kill me for telling this story, but you know, Dan and I built a relationship because I was just interested. I wanted to know everything. Hey, let me talk to your dieticians. And at the time I was doing stuff across country, right? So I had all of these medical licenses.

1:09:05And once we built a relationship, he was like, hey, because they're having trouble getting the CGMs out. He's like, hey, I need a doctor who's willing, who's excited. who talks really fast like me and has some medical licenses. And I was like, cool, I need a CEO that talks faster than me. Like, let's go. So that's really it. Like that really started the whole relationship. And a little bit of other truth here. I was more excited. I was like, hey, teach me, let me use this stuff. And, you know, I'll be your medical director. No payment, nothing like that. That's so crazy. so that helped but it did super charge me into like building my own own clinic and learning more now have you guys become friends or just business i mean what's it have you guys i mean imagine you're you're bugging him that much he brought you in you guys probably built somewhat of a relationship yeah yeah we're bros um we're bros he's always trying to get me to hang out and i'm always telling him like dude i have a lot to do but yes yes we'll go to burning man at some point i'm not having a cgm on when we do that okay how are peptides uh um showing up on cgms are you noticing any changes i'm assuming the growth hormone releasing ones you'll probably see an impact and are you seeing anything with like the like the bpcs and the yeah that's a good question um haven't specifically studied it but you know again even with peptides like in my opinion, very safe molecules.

1:10:37The longer you take them, the longer you have to understand what they do. So some of those growth hormones, secretagogues, if you look at some of the studies, I think it's closer to like a week 11, 12. If you're on it, you may have some increase in IGF-1, which we know is going to change glucose a little bit. So that's a good question. I haven't really looked at that yet, but honestly, another tool in the toolbox to show people. what about um uh hormone therapy how is that improved how is that changing or improving so the guy comes in low testosterone doesn't get doesn't rise from improving behaviors you put them on testosterone what do you see typically in their overall health no in their cgms do we notice anything with with improvements well downstream for sure because then they build

1:11:18Rhett Langley:muscle and then you see yeah sorry yeah so so again to me like having normal testosterone lowers cardiovascular risk. Why? We know it's going to burn visceral fat and that's the major killer. Two, it's going to help you add muscle. I've seen one study where it says it may almost add up. Even without working out, you may have a change in like 7 % to 8%. Really massive. That's wild. That's insane, right? I told you every 4 % lowers your hemoglobin A1C like another 4%. So you do see a downstream effect, right? Right. And then again, having metabolic resistance is going to increase your risk of hypogonadism up to nine to 13 fold, which is like ridiculous.

1:12:03Right. So it's an epidemic and there are certain things you would want better sleep, better mood and better body composition, fixture testosterone. Now, I know you haven't had your clinic for decades, but have you noticed even in the short time you have the rise in young men with like…

1:12:25Rhett Langley:Epidemic. Yeah. Epidemic. In fact, I forgot to say this, but so across the general population, let's say it's 24%, but a new study came out last year where they looked at 18 to 34-year-olds and they gestured, and this was a questionnaire, 34%. Which is insane. And also I personally believe that it's underreported, right? Because, you know, you, you're not, you don't really want to tell someone at that age, maybe you have problems. I know it's underreported because we get DMs and messages from young men all the time that haven't even gone and seen their doctor and talked about it. And so there's not, not everybody's reporting it.

1:13:05Where it gets tricky is, and as a good clinician understands, it's not an absolute number, right? You may be low and not having symptoms, low, or you may be normal and having symptoms, right? You have to look at the number and talk to the client. I would imagine that's due to poor health and probably pornography, which is real common now in young men. A thousand percent. Yeah, so it's probably a good combination of the two. Because, I mean, historically, you would not see any sexual dysfunction in that age group. That's like when you don't have any. Yeah, and that's the other thing to point out.

1:13:36It's not all, like I said, it's not all metabolic health. If a guy comes in and says, hey, I'm looking at porn and I'm masturbating like 37 times a day, I'm going to be like, hey, let's unpack that a little bit. That's probably not healthy. That's not too much. Calm down. Jeez. Right? Justin, wait for you. That's some numbers.

1:13:54Rhett Langley:You're all getting Cialis after the show. Well, good deal. Yeah, dude. Well, this will be great, man. Thanks for coming on. I appreciate you coming on. Yeah, thanks for having me. Kind of breaking this down. I think the future of – I think far more people now are becoming aware of the value of coaching. I think that GLP-1s or GLPs have increased the awareness around it because you lose weight, but you also lose muscle. So now your typical doctor is saying you might need to strength train. And so I think that this is all good. I think we're moving in a better direction than we have in a long time.

1:14:29And you add a glucose monitor to that, and you've got this wonderful – We've never had tools like this. As a trainer, it was just me and my client. But if I had a glucose monitor and if I had a GLP-1 working with some of my clients, I think my success rate would have doubled for sure.

1:14:46Rhett Langley:For sure. Yeah. Yeah, and we're going to see that. For sure. We're going to see that. This is the future. Very close. I would just say, if you're going to set up a clinic, you're going to have a program, you've got to have good coaching. I don't care if you're a doctor or whatever you are. Agreed. You've got to spend time with these people. Agreed. Thanks for coming on, man. Yeah. Thanks for having me. Thank you for listening to Mind Pump.
