Welcome to the you are Not Broken podcast. I'm your host, Dr. Kelly Casperson, a board certified urologist, thought leader, and conversation starter on midlife living, hormones, and sexuality. Enjoy the show.
Hey, everybody. Welcome back to the you're not broken podcast. Excited to have my friend and muscle centric expert with us today, Dr. Gabrielle Lyon. Welcome to the you're not broken podcast.
Dr. Gabrielle Lyon
Well, I'm glad I'm not broken. Thanks for inviting me just in case
Dr. Kelly Casperson
you needed that memo. You're not broken. Of all the people, you're the strongest. Here's the crazy thing about people in muscle. So my brother just got hit by a tree. Gravity plus tree.
Dr. Gabrielle Lyon
He just got hit by a tree.
Dr. Kelly Casperson
My brother just got hit by a tree. He does own a tree arborist company, so trees fall down for a living. And then he thought he should go to the ER to like, just check it out. But. But my brother's like, jacked. He's got like boatloads of armor on him. And I'm like, do you realize that getting hit by a tree kills people? But there's data that people who get into car accidents with more muscle walk away more.
Dr. Gabrielle Lyon
Yeah, it's a really good point. And it's more detrimental to lose muscle mass as you age than it is to gain body fat for precisely the reasons that you're talking. Not just the body armor, the physical protection, which makes a lot of sense, but also the metabolic protection. So as you lose muscle, which, by the way, I did see a picture of you. You are jacked.
Dr. Kelly Casperson
Did you see my back the other day? I should have sent it. Did I send it personally to you? I should have because I always send you my bad things. I'm like, the body fat's too high. I'm like, I should send you my rip pictures.
Dr. Gabrielle Lyon
You did, and I shared one with you. You know, the idea that muscle is just about movement is kind of like old school. It's not. That's just in part of one of the many things that it is valuable for. But this body armor thing is a real thing. And not only that, because your brother tackled a tree. If he was in bed and chilling out for a while, you know what's going to maintain his body and what his body is going to call upon muscle.
Dr. Kelly Casperson
Muscle. Your safety deposit box, friends. So this was like, before I met you, before we bonded in Texas, you had said something. You were like, no doctor is in charge of the muscle. Like, it's not a specialty. And like, it was my first insight of, like, probably one of the many reasons of why muscle is completely ignored by most people is like, there's nobody's in charge of the muscle.
Dr. Gabrielle Lyon
Yeah. I was thinking about the obesity epidemic and, you know, it was not happening. And then in the 70s, we had this massive spike in obesity from the 70s to the 2000s. They didn't think about muscle. Instead they were focusing on the pathology of obesity and not understanding that muscle played such a huge role in it. You know, I've spent some time, a lot of time thinking about this and I realized that because physical activity didn't really decline, it was already a little bit low. It was really the increase in hyper palatable food which caused everyone to focus on calories in, calories out. And nobody discussed movement as opposed to, you know, just thought about muscle in the form of exercise only and that's it. And not like you should do more of it. Didn't think about the quality of muscle. They didn't think about any of those things. Which. Which blows my mind because I think that we're at the precipice of a repeat of history. So from in 1977, we have this obesity epidemic. Muscle goes completely ignored from a metabolic perspective till 2000 and enter the landscape of GLP1. We are on the precipice of swapping obesity for sarcopenia.
Dr. Kelly Casperson
That's exactly right.
Dr. Gabrielle Lyon
If we don't pay attention, we're gonna make the same mistake.
Dr. Kelly Casperson
I feel like it's the pendulum swinging. Cause I think a lot of the pain that Gen Xers have is because we grew up in the 90s with Kate Moss and the Waifs and heroin chic and like thin, thin, thin, straight up and down, no curves. And so it's like we're pendulum swinging from that to obesity back to that. And we're missing this incredible opportunity that still, I mean, I'm surrounding myself with people like you. We're all talking about it, but you don't have to be too far off of the beach to be like, nobody else is actually talking about this though.
Dr. Gabrielle Lyon
Right. I realize that, but we are actually going to solve for that. And that's exactly what we're doing. Especially with your work on testosterone. And, you know, I had another thought. You ready for this next thought? This next thought was the following. A patient could go to their doctor and say, I need a medication that's going to help treat my obesity. Conversely, a patient doesn't go to a doctor or can't really go to their doctor and say, you know what? I need to treat my muscle mass. I Want to be stronger and have more healthy muscle. They're not met with the same kind of respect or interest or even bias or even judgment. The organ of adipose and the organ of skeletal muscle, they're not treated the same. One has a stigma. They both have stigmas. Why is it treated that way? So why couldn't someone go and say, you know what? I need an anabolic agent. I need testosterone.
Dr. Kelly Casperson
Because they'll be labeled as, like, a meathead or aesthetic. I mean, same reason why I wanna lose adipose tissue is cause I wanna look good. But no, there's actually metabolic consequences to too much adipose tissue. Where did the stereotype. You probably know this from, you rain books. Like, where did the stereotype of, like, the muscly meathead come from in the first place?
Dr. Gabrielle Lyon
Do you know? I don't. And it's totally wrong, because we know. So dumb jock. You know, I was at the gym this morning, and this guy was lifting. I don't know, it must have been 350 pounds, sweating everywhere. And he's got leg veins, and his quads were as big as my head. And I thought to myself, what? Everyone who's listening to this is probably thinking, this guy's got to be a genius. So the idea of dumb jock is totally off base. And it's. One of the primary ways that we improve our cognitive function is through training. Yes, the plumbing. So the aerobic activity, but not just the plumbing. It improves vascular health, obviously, and executive function, the ability to do numbers. Again, I did my training in geriatrics. This is all critical. And skeletal muscle is the voluntary control. It's the choice.
Dr. Kelly Casperson
Yeah. I mean, what's so cool about your history is that you trained studying older people in their terminal decade, right? And it's like, that's the power that physicians have. That's the power that I have is like. Like, I see what's happening when you're 82. Like, I see your future. And for people, they don't understand that we study this. There's two groups of people that I ask questions to. If you've been married for more than 50 years, I want to know your secret. And if you're 90 or older, I want to know your secret. And everybody's, you know, everybody's got a gem that they want to. They want to share, but it's like, that's where you came from, is you're like, what if we can do this aging thing differently? Tell us more about, like, your. Aha.
Dr. Gabrielle Lyon
Yeah, There. There was no other possibility. And this was during my fellowship in geriatrics at Wash U. So I did a combined fellowship in geriatrics and nutritional sciences after studying protein and muscle metabolism, who I'm still mentored by with Dr. Donald Layman.
Dr. Kelly Casperson
Go listen to every single ep. You should just, on your website, be like, these are all of the Don Layman episodes.
Please.
Those are gems. Every single time.
Dr. Gabrielle Lyon
He's just a genius. And when I was doing my fellowship, every fellow has a project, and my special project was looking at body composition and brain function. And this woman, you know, you just love these participants. She spent a lot of time with them. We were doing cognitive function, FMRI training. It was just a whole shebang. It was all of it, nutrition. And this one woman, she was a mom of three, and she cycled through the same 20, 30 pounds. And I imaged her brain, and her brain looked like the beginning of an Alzheimer's brain. And I was like, you got to be kidding me. This is what's in store for this woman. Meanwhile, on the weekends, I'm rounding at these nursing homes and I'm reintroducing myself to these patients. And it's just devastating just to their families and their life. I mean, it's awful. And I couldn't not see it, and I also couldn't not do anything about it. And that's really where the muscle centric medicine was born. I had this moment where they were looking at the wrong tissue. This wasn't an obesity problem. Obesity was a symptom of unhealthy muscle. Muscle's a problem, and we're still seeing that today.
Dr. Kelly Casperson
What I'm seeing a lot. So I started my private clinic. I have an in body scanner and a lot of people. For people who don't know in body scanners, it'll do total weight, then muscle mass, and then fat mass. And so if the muscle is low, that's a C, right? A C shape. And then if you're balanced, it's an I shape and then D, like Gabrielle and everybody else. Those are the athletes. So I have a lot of C shaped people. What I mean by that is low muscle mass, high adipose tissue. Universally, they think the way to fix this is to eat less, to get the fat down. That's the default go to. How would you help the C people become more I people?
Dr. Gabrielle Lyon
This goes along with the trend of what we have to lose. We've had a diet problem for the last 50 years, and it's really been all about what we have to lose. It's been focused on fat that redirection has created a lot of problems because at some point, the way to improve body composition isn't to eat less. The way to improve body composition is to address muscle health and match a diet that supports muscle health, which we don't have right now. And that's what becomes really important. It is both resistance training and dietary protein. You need both. They're both two parts of the equation. And you have to be able to make these protein decisions to protect muscle. So if you want to move from a C to an I, the way to do it is you have to train and you have to get your nutrition right. It's a non negotiable.
Dr. Kelly Casperson
I was making a list of all the things I want to talk with you about today and I was like, you know, we're gonna talk about creatine and grams of protein and all this stuff. And I'm like, you know what it is. And you do a very good job when you do public speaking about this mindset. Because if you think it's difficult, it will be. If you think it's hard, it will be. If you think grams of protein's too challenging, it will be like the mindset of body recomp is where I'd say most of the work has to be for people. What do you think about that?
Dr. Gabrielle Lyon
I think that that's exactly right. And, you know, my first chapter of the playbook is all about mindset.
Dr. Kelly Casperson
Nice way to lead with it.
Dr. Gabrielle Lyon
Yep. And the reality is if you cannot be discerning, then you're not going to be able to take the next right step. You have to understand what needs to be focused on. You have to be able to be discerning, allow yourself to think the next right thought and take the next right action. And then ultimately this allows for a very disciplined life so that you get to choose.
Dr. Kelly Casperson
Yeah. A thought that I think a lot of people have. And I got this with my own, like, coaching is like, I deserve this. I deserve the Haagen Dazs mint chip ice cream. I deserve the pizza tonight. There's this very much like entitlement reward behavior. And it's in there. People aren't always aware of it, but it's like it's probably the brain just trying to get some cheap free dopamine. But it's like these things of like, I deserve, you know, a 16 ounce mocha daily. That mindset of that ends up really hurting you in the long run.
Dr. Gabrielle Lyon
Yes. Because you're not able to connect your future self with your present. And you have to be able to create friction and watch the friction and put yourself in position. So what I would say you do, Kelly, is you, you should go and you should go into the Starbucks and you should order that 16 ounce mocha and then you should leave it there or give it to someone else.
Dr. Kelly Casperson
What does that do?
Dr. Gabrielle Lyon
It increases your ability to, number one, maintain your own drive and motivation. And number two, it stings a lot less the fifth time you do it.
Dr. Kelly Casperson
Yeah, that's for sure.
Dr. Gabrielle Lyon
It's this intentional friction.
Dr. Kelly Casperson
Yeah. I mean, to me it was like, you know, I haven't had alcohol in four years and it's like, it's hard in the beginning and now I'm like, God, why would I ever put that in my body? You know? And it's like you become the person who lifts the weights. You become the person who doesn't have the alcohol. Like you have to become something different than you already are. When you're looking at that C shaped body comp and realizing like it's not as simple as just not eating.
Dr. Gabrielle Lyon
And if you don't believe that you have the time for it, how would one manage the time for illness? You don't have the time or the luxury not to. And that becomes really critical because I think a lot of your listeners, they're on hormone replacement or they're thinking about all of the things that you talk about. Yet there seems to be a disconnect between action and interest. And the way to bridge that gap is you think about what inspires you, what motivates you, and then you don't wait for the moment where you feel ready. You decide that these are the things that you're going to do. And then you fall back on your own attributes and you fall back on your behaviors and you plan for your weaknesses. Over time, you make massive improvements and you then set a standard that you always hit feel really like always. Yeah. Because you set a standard that's within your wheelhouse. So if you're starting to work out, you don't start with a five day a week program. You start with a three day week program. That's what I did in my playbook. The playbook is a training program for everybody. I know you have a trainer, but you should really try it.
Dr. Kelly Casperson
Of course I'm going to try your program. Of course I'm going to read your book.
Dr. Gabrielle Lyon
So six weeks, let's try it. Let's see how you do on a dumbbell program for six weeks. Dumbbell plus high intensity interval training for six weeks.
Dr. Kelly Casperson
I love it.
Dr. Gabrielle Lyon
Body Changes, nutrition changes, all of it.
Dr. Kelly Casperson
I just saw somebody who had dropped some weight on intermittent fasting. She was giving herself an eight hour feeding window and she's under muscled and was having trouble kind of dropping the next ten pounds that she wanted to drop. And I was like, my understanding is intermittent fasting works for some people. Everybody's different, they got to figure it out. But it's hard to get the amount of protein in, in an eight hour window. So where would you take somebody who was like, hey, I had some success with intermittent fasting, but now I don't know. You know, I like that I lost some weight on it. But I, I'm like, I was starting her with, just write down how much protein you're doing in a day because most people don't know if you don't track it.
Dr. Gabrielle Lyon
Yeah. So 100 grams is the minimum that you need. And also as your calories decrease, your protein has to increase. Protein is not a percentage of calories, period. Protein should be thought of in terms of grams, especially if you're over 40. If you're over 40, you have to protect muscle at all costs. Intermittent fasting is fine. There's no issue with it. It's not a magic bullet. It does seem to work well for some people. The idea behind intermittent fasting is it restricts the feeding window. What I would say is if you are eating in that eight to nine hour window, here is the way that I would do it. The first meal of the day should have around 50 grams of protein. It could be done through food, it could be done through a protein shake, it could be done through additional essential amino acids, which is what I use. So for example, I use Body Health's essential aminos. If I'm only going to do a 25 gram of protein breakfast, in order to bump it up, you add in essential aminos, you now have a higher protein breakfast without getting a whole bunch of extra calories or a whole bunch of extra volume. Right. So if she's not hungry, chances are as she's streamlined her eating, she's less hungry. So that 50 grams of protein in the morning, number one, will reduce her hunger because it releases GLP1 at a gram of 30 or more. The second thing is it allows her with balanced carbohydrates to maintain her blood sugar. And then with her second meal. Do I care so much about it? I don't. But it should not be skewed one way or the other. It shouldn't be like high carbohydrates. There should be Protein. And then her last meal before she goes back into her overnight fast, should be another 40 to 50 grams.
Dr. Kelly Casperson
I was talking to somebody about this, and I learned this from you and Donald Lehman is as we age, I'm gonna F it up. But basically the body needs more protein to kind of push into the machine to get it working. Caveat. If it's a well oiled machine, meaning like you have muscles that you are using, you might not need as much, but just the aging process kind of. The protein efficiency. Is that the right word for it?
Dr. Gabrielle Lyon
That's right. So, so what happens?
Dr. Kelly Casperson
I'm like a barbarian re, like resaying what you say. I'm like, you gotta like push more with the protein.
Dr. Gabrielle Lyon
Yeah, girl. Yeah, you got it. So what happens as we age, which is interesting, is this aging phenomenon called anabolic resistance. Anabolic resistance is skeletal muscles inefficiency of recognizing and being stimulated by protein. Protein is made up of amino acids. Not just essential amino acids, but amino acids. There's 20 different amino acids. They all do various things, nine of which are essential. Of those nine, skeletal muscle is exquisitely sensitive to leucine. This is the stimulator amino acid that is necessary to stimulate an MTOR complex that then stimulates muscle protein synthesis. And the body turns over four times a year. As we age, we become less efficient at turning over protein. You know, you might see that your skin gets a little worse or your hair gets a little not so great. Well, your hair is great, but you see what I mean? So the efficiency of protein decreases. However, one can stimulate muscle, older muscle, to the same degree as younger muscle with the addition of protein. And then there's a synergistic effect when it comes to stimulating muscle with exercise followed by protein. And this becomes important because it allows us to overcome the aging effect. And if we believe that skeletal muscle is the organ of longevity, which you and I are friends in real life, you better believe, which I know you do, Then we have to reorient ourselves to a nutrition plan that supports muscle. And right now we don't have that. Right now we are eating too many calories. And we're highly focused on fat. And we're focused on fat, but yet 55% of our calories are coming from carbohydrates.
Dr. Kelly Casperson
Yep, I'm seeing a resurgence of go vegan to get your cholesterol down.
Dr. Gabrielle Lyon
Please don't.
Dr. Kelly Casperson
I'm seeing it. It might be in my house. It might be in my house right now with somebody visiting.
Dr. Gabrielle Lyon
Okay, now here's, here's the deal.
Dr. Kelly Casperson
Tell us the deal with that.
Dr. Gabrielle Lyon
Majority of vegans are younger. It seems that the majority of them go back to their normal nutrition plan within six months.
Dr. Kelly Casperson
So vegan isn't sustainable for most people?
Dr. Gabrielle Lyon
For most people it's not. So if we think about the numbers and we want to age well, 40% of women over the age of 65 are deficient in protein.
Dr. Kelly Casperson
Can you test that or is that just them not eating 100 grams a day?
Dr. Gabrielle Lyon
So it's based on the Recommended Dietary Allowance, which is set at the minimum, which is already too low, because it's frankly an irrelevant number because it's based on nitrogen balance studies, which is irrelevant because nitrogen balance doesn't have any health outcomes. If anyone knows what a nitrogen balance health outcome is, please call me because I'm still waiting.
Dr. Kelly Casperson
But my question is, is it, is it that they have low muscle mass on my in body that I can tell them they're deficient in protein, or is there a blood test that I can tell them they're deficient in protein, or do I have them track their protein and because It's a below 100 grams a day, they're deficient in protein?
Dr. Gabrielle Lyon
Well, this is complicated because protein deficiency doesn't show up immediately. Protein deficiency can come in a number of forms. One would argue in part that potentially protein deficiency looks like sarcopenia. And again, we're talking about protein. But the reality is there's 20 different amino acids, all do different things. Threonine for mucin production, phenylalanine for serotonin production, leucine for muscle stimulation. And we don't eat leucine and threonine and phenylalanine. We eat whole foods. And so the reality is, when we see how, you know, you could do a blood test and say your albumin is low, okay, fine, but that's an acute marker, maybe over a period of time. But how I would say that someone's deficient in protein is a number of ways. Number one, you do have to track, you have to know. And number two, are they maintaining or are they losing muscle? Again, is it protein? Who knows? They could have cachexia or they could be not moving. There's a whole host of things that one could or could not do. That's what makes it so hard. And that's why people argue so much about protein. Because if you think about it, it takes 14 to 16 weeks to see changes, small changes in muscle on measurements like adexa. So if you're looking at the same person, you can't expect. Doing a 10 to 12 week study, people say, well, it didn't show any change in lean body accretion or whatever. Well, yeah, what'd you expect?
Dr. Kelly Casperson
So if I have an inbody that's in my hallway, my trainer's like, Kelly, you jump on that thing twice a year. And I'm like, but it's in my hallway, like what's too soon? Where it's just gonna F with you psychologically. Cause it's variation. That's not real.
Dr. Gabrielle Lyon
Totally up to you.
Dr. Kelly Casperson
Okay.
Dr. Gabrielle Lyon
So if you are an untrained individual, you will see changes and you will see changes fast. Right. If you're untrained, you'll see it in a month. If you're a trained individual, then you won't see it. It'll take a long time.
Dr. Kelly Casperson
Yeah, I think that, you know, but the whole like, especially if you're trained to get that extra half a pound, to get that extra pound, like it is hard earned. Like I would like to go through a drive through and buy some muscle. That would be my preference.
Dr. Gabrielle Lyon
And also friend, why is it so much easier to gain body fat than to build muscle? And then my favorite and ladies, don't do this. My favorite excuse in the world is don't train because you're going to get too bulky.
Dr. Kelly Casperson
Dude. That will not die. That will not die.
Dr. Gabrielle Lyon
Oh my God, you are so funny.
Dr. Kelly Casperson
I love like, I love it. Like they, there's somebody did this on Instagram a while ago. Like they're like, they take the men in the gym and the men are like, we wish, we wish we could get bulky. Like they have 10 times the testosterone, way more upper body strength and they're like not getting bulky over here. Like even the dudes aren't getting like whatever bulky means, by the way.
Dr. Gabrielle Lyon
Exactly. There's. I'm still trying. Yeah, yeah, I'm still trying. And by the way, you and I are the same size. We're both still trying.
Dr. Kelly Casperson
I have the don't start, don't die in the winter body type of like I will put on ass fat faster. You put me on a couch and give me a big max, I will put on as fat quickly.
Dr. Gabrielle Lyon
See, I'm the opposite. I won't. I don't even know where my ass is. It's gone on vacation forever. I have zero ass. Zero.
Dr. Kelly Casperson
I love. I was just at Vonda Right's conference in Orlando which I highly recommend to everybody and somebody was like the non medical term as fat is actually like protective healthy fat. It's the visceral fat that's inflammatory. It's like literally a different breed that shouldn't. It shouldn't be called, like, they both shouldn't be called fat. Right. Because they're so different.
Dr. Gabrielle Lyon
Well, I'm going to drop a bomb. The next iteration is. IMAT is intramuscular adipose tissue, which is probably more relevant and drives disease and metabolic outcomes. So body fat, probably in the next five years doesn't matter nearly as much. It's almost irrelevant.
Dr. Kelly Casperson
Like, body fat percentage is becoming the way of the bmi. Meaning it doesn't tell you enough.
Dr. Gabrielle Lyon
Yes, got it.
Dr. Kelly Casperson
Because if my body fat is 30%, but it's not visceral.
Dr. Gabrielle Lyon
So here's. And I really. This is probably the one thing that I've changed my mind on. I used to believe when I was in my fellowship that you couldn't be fit, you know, the fit fat phenotype. However, I was wrong. And the reason I was wrong was because when you are moving and just exercising, whether your body composition changes or not, you're decreasing intramuscular adipose tissue, which is that marbling of that steak. And that is very empowering. You think about linemen. Linemen. And if you look at their blood, they're, you know, I'm just, I'm picking linemen. But not, you know, not everyone. But this fat fit phenotype exists. And in part, I believe that's because they have low intramuscular adipose tissue. So it's the intramuscular adipose tissue that is more related to insulin resistance and diabetes and cardiovascular disease than the percent body fat. But we haven't been testing it and it's not really available.
Dr. Kelly Casperson
Yeah, I was going to say, are you going to get a cat? Is a CAT scan, an mri, like to actually see it? Yeah, I think they would come up with some sort of like, muscle ultrasound impedance thing at some point that can detect.
Dr. Gabrielle Lyon
They do, but it's highly variable. So you know that they have it. It would be great. There's too much variation. Ultrasound is there, we're just not there yet. At a population level. Remember, we looked at BMI not for intervention, but at a population level. And then we moved to percentage body fat. And then we moved to, well, not quite just body fat, but then there was waist, hip circumference and these other markers. Great. And then body fat is in there, and then visceral fat. But if you think about it, there's liver fat and people are like, okay, well, what do we do with that? And then there's muscle fat and potentially muscle fat may be even more detrimental than liver fat. Intramuscular adipose tissue over time decreases contractility, decreases strength, changes the metabolic regulation of muscle. So muscle. Most people don't realize this, but muscle at rest burns primarily fatty acids. If you over consume carbohydrates and you flood the system with carbs or glucose, you force it to burn and dispose of carbohydrates. But at rest, muscle primarily burns fatty acids.
Dr. Kelly Casperson
Interesting.
So at rest your muscle is consuming fatty acids. If you foie gras it, it'll become a glucose sink for you. That's where the fat, the marbling comes from. Though. Is the glucose sink and the carbs?
Dr. Gabrielle Lyon
Well, yes, and there's a number of reasons as to why. Well, number one, if you over consume carbohydrates, muscle has to handle the glucose and also liver in addition. Now you've deranged metabolism. And here is going to be a shocking, not so exciting, I'm sorry, truth. But if roughly 73% of Americans are either overweight or have obesity and the majority of people are sedentary, then by definition they have unhealthy skeletal muscle. That means 40% of their body weight is probably in there marbled. Now if the average American diet is 300 grams of carbs a day, they're doing three oral glucose tolerance tests a day. There is a derangement in metabolism if someone is sedentary. And we calculated, myself and Dr. John Layman, because we're working on a paper, we calculated and maximum disposal rate is 40 grams in a two hour period. This is very particular. There's the obligatory use which is red blood cells and the organ systems. And skeletal muscle at rest burns very little. In fact, I calculated all these numbers. Skeletal muscle at rest is not very active. What's happening is, is our red blood cell which has a constant requirement of. Are you ready for this? 4 grams per hour, which is not much skeletal muscle. Guess how much glucose it uses per hour at rest you're going to die.
Dr. Kelly Casperson
Not much because it uses fatty acids,
Dr. Gabrielle Lyon
2 to 3 grams. Okay, so total fasting, sedentary, you're like, you know, you're looking at 40 grams per hour in a two hour period. So it's 20 grams per hour.
Dr. Kelly Casperson
Do you ever see America getting to like a low carb lifestyle, like an, or an earn your carbs if you exercise that day, sort of thing of like it's not meat, that's the enemy. But I think most people don't know that. And to me I'm like it's not the, the hamburger, it's the bun on the burger. That's what makes the hamburger bad.
Dr. Gabrielle Lyon
That's absolutely right. And the other component to that is people are overeating carbohydrates and overeating calories. That's it. Our diet is 11% saturated fat. It's a carbohydrate issue. Do you know how we see this? Because we have elevated triglycerides and elevated insulin and elevated glucose. These are diseases of or these are indications of unhealthy muscle rather than it's not about the symptom of obesity. So triglycerides. So here's what we did. So in research and in the weight management clinic that I ran, when you reduced carbohydrates to under 140 grams a day, you could reduce triglycerides by 20%. And that's how we figure out if people are following their nutrition plan.
Dr. Kelly Casperson
Ah, so triglycerides is the marker of foie gras.
Dr. Gabrielle Lyon
Well, foie gras is fat, so.
Dr. Kelly Casperson
Well, I think of, I think of foie gras is like force feeding. So like if you're over, if you're over carved, you're force feeding the goose. I am crude and just trying to figure it out at this point.
Dr. Gabrielle Lyon
You're hilarious. You're actually also an excellent interviewer.
Dr. Kelly Casperson
My podcast is six years old. It's a first grader at this point. I'm a pro.
Dr. Gabrielle Lyon
Hey, there's a lot of people that do podcasts for a long time. And you're pro status. You're pro at us.
Dr. Kelly Casperson
Probably why it's going so well. Thank you. Let's do creatine, huh? Yes. No. Every day, 10 grams. Getting hot. Creatine is getting hot for brain health.
Dr. Gabrielle Lyon
And creatine has been like the OG forever. It's great for brain, but it's interesting. More the data is in older individuals. I would say the more convincing Data is like 65 and up. But it doesn't hurt. And just because we don't have the data yet. Well, anyway.
Dr. Kelly Casperson
Yes, yes, yes to creatine. As I said, safety profile and cost profile. It seems like if you're going to pick a non negotiable, that's a good one.
Dr. Gabrielle Lyon
Yeah. So Darren Kando, he is the expert in creatine. Darren Kando, Creatine also essential amino acids are. Ladies, you're not eating enough protein. Essential amino acids. I use Body Health. They're amazing. I use the packs. You and I travel a lot. I travel with the packs.
Dr. Kelly Casperson
So the packets.
Dr. Gabrielle Lyon
Travel with packets.
Dr. Kelly Casperson
Essential amino acids. What's the brand?
Dr. Gabrielle Lyon
Body health. Amazing. Amazing. Okay. See the other aspect. In women, it seems that omega 3 fatty acids seem to affect women. There's some pretty good data. I don't know if we know everything about it or why, but I think that that's a great one. Omega 3 fatty acids. You can also test it in the blood.
Dr. Kelly Casperson
Omega index. Yep, I've just started getting that on.
Dr. Gabrielle Lyon
Some patients want that about 10. And then the other one is urolithin A. So URL with an A. If you're not on it, you should be. And that's mitopure. Timeline has an. I mean, it's the only one that I use. Use the gummies. I'm. I travel with the gummies. But basically it helps with mitophagy, which is the cleaning out of old cells, old mitochondria. So these are extra. Right. You want to have whole foods. So, number one, do you say creatine or do you say essential amino acids? I say essential amino acids because creatine is going to help if you don't have any muscle. I mean. Yeah. So it'll help brain. So that's not true. And then essential amino acids. So as women get older, their appetites decrease with the use of GLP1s. People are not eating enough.
Dr. Kelly Casperson
That's true. It's a weird paradox, right? Because here we are saying people are overeating carbs. And then we sell. We say they're not eating enough. But what we mean is protein.
Dr. Gabrielle Lyon
Yes, exactly.
Dr. Kelly Casperson
Because I think they're like, we're like, we're eating too much, but we're not eating enough. Right? You're not eating enough of the proper things. But, dude, proteins take longer to eat.
Dr. Gabrielle Lyon
No, it does. That's why you take a shake.
Dr. Kelly Casperson
Yeah. Oh, I got. I love my shakes. Okay, let's talk about collagen. Because collagen will say it's 20 grams of protein on the label. And then I listen to brilliant people like you, and you're like, yeah, but they're. It's kind of crappy quality protein.
Dr. Gabrielle Lyon
Yeah, no, it's zero quality protein.
Dr. Kelly Casperson
It's zero quality protein. You heard it here, folks. So to me, I'm like, this is what you had told me. It was like, if you're good on your 130 grams of protein, add in your collagen. Fine, but don't use it as counting towards your 130 grams of protein.
Dr. Gabrielle Lyon
That's right. And I love collagen. So I use collagen every day, almost every day. I don't do anything every day. I don't even brush my teeth every day. No, I do, but collagen has a protein score of 0. Ladies. Also another thing. Low muscle mass is typically indicator of low bone density. Low muscle mass also is an indicator of poor cognitive function as muscle mass decreases. I was just looking at this because I'm giving a talk in front of, like, 9,000 doctors tomorrow, Friday. That 10% loss of lean body mass, which I'm saying lean body mass because, again, we haven't been testing muscle. 10% loss of lean body mass decreases immunity, increases risk of infection, decreases at 20%, decreasing wound healing, increased muscle weakness. Now, can you imagine you're losing 20% of lean body mass plus infiltration of fat because you're not training? Not good. It's not a good look.
Dr. Kelly Casperson
It's not a good look. It's really not a good look. Okay, so CGMs, continuous glucose monitors are now available over the counter, which is awesome. Stilo. And another one that begins with an L. There's two companies right now that are. You just literally go online and you can just buy your own continuous glucose monitor, which is sweet. You don't need a doctor to access that anymore. Do you recommend it? Do. Should people at least, like, when people come to your practice or you, like, slap this thing on for a month so you can start learning?
Dr. Gabrielle Lyon
Not anymore. Here are the reasons why I would have someone use a continuous glucose monitor. Reactive hypoglycemia. If someone is saying to me, I'm waking up in the middle of the night hungry, or like, I'm catching my breath and they don't have sleep apnea. Again, what I have seen is reactive hypoglycemia is one thing. If they are saying they have low blood sugar, let's prove it. If you've got it and you need those cookies, let's prove it. If somebody is feeling very erratic, because when blood sugar is low, it increases catecholamines, so it increases this feeling of anxiety. Is it anxiety or do you have a rebound from low blood sugar?
Dr. Kelly Casperson
So you're doing it more for the low end of things than for people to understand. If they're spiking with white rice, et
Dr. Gabrielle Lyon
cetera, et cetera, you expect a certain glucose response. And also, we have a great dietitian on our team. A Martin is. If you look at her reviews, people are obsessed with her. I've never had someone in the practice that people love more, like, ever. Except for our Dr. Lisa. Those two, I mean, they like them better than they like me.
Dr. Kelly Casperson
I love that. Is that the best thing? So awesome. But do you, do you use it? So let's say somebody comes in and their, their fasting glucose on their Labs is like 250 or something like that. Do you have them wear one for a while so they can see like the behavior that results in a lower glucose?
Dr. Gabrielle Lyon
Dude, your blood sugar, your fasting blood sugar is 250. I'm treating you.
Dr. Kelly Casperson
Yeah, yeah.
Dr. Gabrielle Lyon
What's happening here?
Dr. Kelly Casperson
What's, what's happening there? Too much fo is what's happening there. Okay, so what are doctors getting wrong?
Dr. Gabrielle Lyon
The list is long and cumbersome. I mean, listen, the doctors that I know aren't getting stuff wrong because they're amazing humans like you and our friends. They are getting wrong. Number one, the anabolics. They're getting wrong the importance of muscle. They're getting wrong testosterone. They're getting wrong nutrition. People are still confused about nutrition. It's not confusing. It's not that confusing. You've got to protect muscle at all costs. Muscle is your medicine. Muscle is what is responsible for your aging trajectory. That's what it is.
Dr. Kelly Casperson
It's insane. What do you say to a woman? Let's say she's 53 and she's, let's say she's a C on the embody and she's got more body fat and she's like, can women really, can we really turn this around? Like, she looks at like her 20 year old son who can just drop calories like nothing, although he's keeping track, like he's working for it. What do you say to the midlife woman who's like, is it possible for me? And I know you just interviewed Train with Jones, so I know that story. But like, what do you say to these people who are like, man, really, really, Dr. Lyons?
Dr. Gabrielle Lyon
I mean, I've seen it a million times. Of course it can be done. And it has to be.
Dr. Kelly Casperson
It has to be done.
Dr. Gabrielle Lyon
It's not an option. And you can always get stronger and it happens quickly.
Dr. Kelly Casperson
I was working, I'm like, I haven't, I don't practice regularly hanging from a bar. So recently I'm like, I will practice hanging from a bar. And it's very uncomfortable. But you get better pretty quick.
Dr. Gabrielle Lyon
You're also littler, you're also active. You also seem to be good at things you put your mind to. So, I mean, you and I are the same size. You're a small, you're a small human. So for you, it's going to be easier.
Dr. Kelly Casperson
I have a much bigger ass than you.
Dr. Gabrielle Lyon
Yeah, well, everybody does.
Dr. Kelly Casperson
You were on stage at south by Southwest, like, the day after. I was on stage at south by Southwest, so that was super fun. It was, like, two years ago now. Two and a half years ago.
Dr. Gabrielle Lyon
Yeah. But we've seen each other since then, haven't we?
Dr. Kelly Casperson
Tragically, no.
Dr. Gabrielle Lyon
That's. Well, first of all, I feel like I've seen you.
Dr. Kelly Casperson
I just don't. I haven't come to Texas enough.
Dr. Gabrielle Lyon
But you're actually good enough guests that maybe we could do it remote.
Dr. Kelly Casperson
Such an honor. Okay, but you were at south by Southwest, and it was. People were doing a Q and A, and somebody asked you, how do you find enough time? And your mindset shift on that person was razor sharp because you said something like, you don't have time not to do this.
Dr. Gabrielle Lyon
Yeah.
Dr. Kelly Casperson
And it was just like, there's like, no mamby pamby excuses here.
Dr. Gabrielle Lyon
And I think that people don't actually like that about me. And I'm sorry, there's nothing I can do about it. I definitely think that it makes me not a fan favorite, but I wouldn't be being a good doctor, nor would I be being a good friend if I told you all of the reasons
Dr. Kelly Casperson
why, like, we got here. Because we're coddled. Like, did you read the book the Comfort Crisis by Michael English?
Dr. Gabrielle Lyon
You sent that to me.
Dr. Kelly Casperson
Yeah. Did I say it's so good? He's just like, you not moving is killing you.
Dr. Gabrielle Lyon
But also the reality. There's one more thing beyond that is that women need to be having these conversations because all of the individuals in there were men. And it's missing the connection, the female connection, the. All of those things are somewhat missing.
Dr. Kelly Casperson
I think the mindset shift also that comes from being strong. Like, being strong people feels effing amazing.
Dr. Gabrielle Lyon
Totally.
Dr. Kelly Casperson
But you have to, like, become the person. Right. It in itself is personal growth worth having. What are you working on for 2026? We got the book coming out end of January.
Dr. Gabrielle Lyon
Starting my next book, the Playbook, January 27th. I'm very excited. It's the book that I wish that I had written the first time.
Dr. Kelly Casperson
I love it.
Dr. Gabrielle Lyon
It's a very personal book to me, and I am proud of it. And it has a ton of recipes and protocols. Exactly what you do. In fact, I want to challenge you to do it. You know, we'll get Rachel Rubin to do it, too. Let's. We'll get on a group text let's do it together. Okay, I'm down. Why do. Do I have to do it? I already do it.
Dr. Kelly Casperson
We're already on a group text together. Just tell us what you want to do.
Dr. Gabrielle Lyon
I have to do the pro. Redo my program. I'm in a different phase of my program. I go back.
Dr. Kelly Casperson
Oh, no. You know you do. You do.
Dr. Gabrielle Lyon
You.
Dr. Kelly Casperson
Rachel and I will start at the beginning.
Dr. Gabrielle Lyon
Okay.
Dr. Kelly Casperson
We'll figure this out, everybody, and then everybody can watch us.
Dr. Gabrielle Lyon
Yeah, for sure. So that is something I'm really proud of. And I don't say that lightly. I'm not a. I'm going to give myself compliments because it's just not my way. I'm working on my next book, the third book, and I'm still a practicing physician. And what else am I working on? I've got some other really exciting projects.
Dr. Kelly Casperson
We want the female muscle and sex paper because you did the female. You did the male muscle sex paper, which is excellent, as I have two minutes on this podcast. Last muscle is good for your sex life. She published that for men and she's working on the female one, I hear. Allegedly.
Dr. Gabrielle Lyon
Yeah, we're working on a paper. Allegedly.
Dr. Kelly Casperson
So many things. I'm busy changing the fda. Well, the FDA is helping.
Dr. Gabrielle Lyon
You were great on that, though. I watched it. You were fantastic. I was so proud of you. I was like, I know her. She's famous.
Dr. Kelly Casperson
Like, that was a good two minute talk. Nailed it.
Dr. Gabrielle Lyon
You were great.
Dr. Kelly Casperson
It was great. Thank you. Well, thank you for coming on my podcast and loving on me and letting me love on you and helping all
Dr. Gabrielle Lyon
the women and I'm waiting for you to come online.
Dr. Kelly Casperson
I'll come to Texas at some point.
Dr. Gabrielle Lyon
No, you won't. I'm going to have to put you on remote, which is such a waste.
Dr. Kelly Casperson
I like Texas. I love how big it is. My grandparents lived at the bottom of i5, i35, all the way down i35. So Texas is a little sweet to me.
Dr. Gabrielle Lyon
You can come train with me. Stay my house. I have saltwater pool. I have a saltwater pool.
Dr. Kelly Casperson
I love that I have a sauna. We'll talk about that next time. All right, my love. Until next time. Lift weights, be strong, get after it.
Dr. Gabrielle Lyon
Aging is inevitable.
Dr. Kelly Casperson
Suffering is optional.
Dr. Gabrielle Lyon
That's right.

Guest: Dr. Gabrielle Lyon
Release Date: January 25, 2026
In this episode, Dr. Kelly Casperson is joined by Dr. Gabrielle Lyon, a physician and thought leader in muscle-centric medicine. Together, they challenge prevailing health narratives that overlook the importance of skeletal muscle, especially for women in midlife. Their discussion covers the metabolic and protective power of muscle, why traditional medical care ignores muscle health, and practical steps for listeners to maximize their muscle health and longevity. The tone throughout is direct, empowering, and laced with humor, pushing listeners to reframe their mindset about aging, diets, and fitness.
“Aging is inevitable. Suffering is optional.”
— Dr. Gabrielle Lyon (41:38)
The message of this episode is clear: prioritizing muscle health—through resistance training, sufficient protein intake, and mindset upgrades—can transform aging, empower women, and challenge the status quo of medicine. Listeners are urged to take control now, with small, sustainable steps that pay dividends for decades to come.
