The Autonomic Nervous System Data Nobody Is Talking About

Dr. Kristen Holmes, global head of human performance at Whoop, joins me to break down her new book "Aligned." We cover why fear keeps your body in a sympathetic, aging-accelerating state, why late-night eating rivals alcohol in damaging resting physiology, and a striking new finding: long sleepers have worse mortality outcomes than short sleepers.

Are You Aging Faster Than You Should? - Dr. Kristen Holmes | GLS #230

Most of what we call "aging" may not be about time at all. It may be a nervous system stuck in stress, quietly draining your sleep, your recovery, and your long-term health. In this episode, Dr. Gabrielle Lyon sits down with Dr. Kristen Holmes to discuss: - Why the hallmarks of aging- inflammation, mitochondrial dysfunction, cellular decline may be symptoms of a dysregulated autonomic nervous system, and how much of your HRV (47–65%) is genetic versus trainable - How your sleep is decided during the day, not at night, and why perceiving your day as "threatening" keeps your HRV suppressed and

The Protein Bar Ratio Most People Never Check

Choosing a protein bar has always felt like a gamble, since most labels highlight a protein number without disclosing what percentage of total calories that protein represents. David Protein delivers 28 grams of protein at 150 calories with zero grams of sugar, putting roughly 75% of calories from protein, a ratio that outperforms most bars on the market. This clip breaks down why that ratio matters more than the headline number. Subscribe and save 10% on every order at https://bit.ly/4hOdQnP

Is Your Hair Loss Normal or a Warning Sign?

Everybody cares about their hair. Including me. I joined Fox & Friends to break down normal shedding versus abnormal hair loss, which can be a difficult distinction. Androgenetic alopecia measurably impairs quality of life and emotional well-being (PMID 34037674), which is exactly why I have treated this in clinic for years at Strong Medical. During the segment, I walk through the potential side effects of common hair loss medications, and why I always start by analyzing potential underlying health and nutritional deficiencies driving the problem, not just the symptom on the surface.

The Obesity Crisis Was Never About Obesity

What looked like an obesity problem was a muscle problem. Obesity is, in part, a symptom of unhealthy muscle. An epidemic of sarcopenia is repeating the same pattern that caught researchers off guard in the 1970s. Like and subscribe for more clinical reframes like this.

89% of Avocado Oil Label Might be Fake

Recently, I was on Fox & Friends. The topic: 89% of Avocado Oil is Fake. Researchers found that 89% of avocado oil products tested contained cheaper substitute oils despite avocado oil being the only oil listed. I went on Fox & Friends to break down why this is a massive transparency breakdown and a medical risk for anyone managing food allergies. In this video, I break down why third-party testing matters, how to spot misleading labels, and tactical ways to protect your kitchen. Like and subscribe for more clinical breakdowns like this.

Electrolytes Aren't About Thirst

Most people think electrolytes are about thirst. They are not. Sodium, potassium, and magnesium are what your muscles use to fire and contract. Sweat depletes sodium fastest. Plain water alone dilutes what remains, working against your muscle rather than for it. Hydration keeps muscle firing, but gives it nothing to rebuild with. What I check on a label: sodium and potassium for what you sweat out, magnesium for ATP production, zinc for tissue repair, and all nine essential amino acids for rebuilding. Perfect Amino Electrolytes by BodyHealth checks every box. Get yours for 20% off: https://

Why You Feel Drunk After Eating Carbs

The Rare Condition Where Your Body Makes Its Own Alcohol A defendant once beat a DWI charge by proving her own gut was producing ethanol internally from the food she ate, registering levels far above the legal limit despite never drinking. This episode unpacks the science behind that rare condition and traces its surprising connection to muscle physiology. Watch here for the full episode: https://bit.ly/4xQwShR

The Gut Yeast That Brews Ethanol From Every Carb You Eat | GLS #229

Blowing four times the legal limit on a breathalyzer usually means one thing, but in 2015, a judge dismissed a DWI because the driver's own gut was fermenting alcohol from an ordinary carb-heavy dinner. It's called auto-brewery syndrome, and the fuel it runs on is the same load your muscle is supposed to be clearing from your blood. In this solo episode, Dr. Gabrielle Lyon discusses: - How gut yeast overgrowth turns everyday carbs like pasta, bread, and rice into ethanol that registers as real intoxication, brain fog, dizziness, and all - The specific risk factors that open the door: dysbiosi

The 1 Macronutrient High Performers Skip After 60 - Arthur Brooks, PhD | GLS #228

Most people chase happiness as a feeling and wait for certainty before making big decisions, and both instincts quietly backfire. Dr. Arthur Brooks joins Dr. Gabrielle Lyon to break down what happiness is and how to act on it. In this episode, Dr. Gabrielle Lyon and Dr. Arthur Brooks discuss: - The three "macronutrients" of happiness - enjoyment, satisfaction, and meaning, and why pursuing pleasure alone leads to detox, not happiness - A usable rule for any hard decision: aim for roughly 80% excitement, 20% fear, and near-zero "deadness" once you have about 80% situational awareness - Why s

Happiness Isn't a Feeling. It's Three Things.

The Three Things Happiness Actually Breaks Down Into Dr. Arthur Brooks joins me to explain why happiness is not one feeling but rather three measurable components: enjoyment, satisfaction, and meaning. In this episode, I ask him why treating happiness as something you feel rather than something you build leads people astray, why avoiding enjoyment entirely carries real risk, and why poor decisions made when you were younger do not permanently close the door on meaning later in life.

The Trait You Think You're Missing Is Actually a Skill You Haven't Built

The Trait You Think You're Missing Is Actually a Skill You Haven't Built Consistency is not something people either have or lack. It is a practice, built through repetition rather than motivation. In this episode: why waiting to feel ready is present bias in disguise, how radical accountability closes that gap, and why the people who look naturally disciplined simply executed the baseline behavior on days it felt wrong.

Does Your Menstrual Cycle Actually Affect Your Strength?

Hormonal fluctuations do not reliably change your muscle output. The data does not support that claim. Exercise metabolism PhD Dr. Alyssa Olenick breaks down what research suggests: studies controlling for hormones find no consistent relationship between cycle shifts and performance. What shifts is perception. Pain tolerance, motivation, and drive are affected by the drop in progesterone and estrogen, and sensitivity varies between women. Not a performance limitation. A perceptual one. Watch here for the full episode: https://bit.ly/4gyKatz

Does Minoxidil Affect Your Blood Pressure?

Minoxidil. Here's the good news for anyone worried about their blood pressure: at the low oral doses used for hair loss, it barely budges. What you'll actually notice is more hair, some mild swelling, and a heart rate that runs a touch faster (PMID 39521141, PMID 40142611). One caveat worth flagging: oral minoxidil for hair loss is off-label; only the topical form carries FDA approval for this purpose (PMID 40142611). Topical minoxidil. The trade-off here is simpler and mostly cosmetic: an irritated scalp is the main thing to watch for. Nutritional interventions. Fixing a documented deficien

Your Muscles Are Keeping Score

You keep telling yourself life will slow down next month... and while you wait, your muscles keep score. The waiting time will cost you. As we age, the amount of protein it takes to trigger muscle goes up, making it harder to get the same stimulus like you did when you were younger. It is ironic that during the season of life when you have the least time, your body needs you to get it (diet and training) right. If you miss the opportunity to fuel and train for muscle health, it only gets harder. Miss it enough times, across enough busy years, and you end up under-muscled and frail. Having i

How Much Fiber Do You Really Need

Only 5 to 6 % of Americans meet adequate fiber intake. But fiber maxxing on a GLP-1 carries real clinical risk. A 2025 case documented a 45-year-old woman who developed a complete small bowel obstruction from fiber volume alone, requiring surgical removal with no other risk factors. GLP-1 medications delay gastric emptying, creating a physiological traffic jam. Nearly half of patients discontinue within one year, with GI side effects as the primary driver. GLP-1 and fiber are partners that need to learn to work together.

The Muscle Myth GLP-1 Users Have Been Lied to About | GLS #227

You might think the number dropping on the scale is the whole win, but on a GLP-1, a meaningful share of what you're losing may be muscle, not fat, and the fiber that's supposed to help can quietly make things worse. In this solo episode, Dr. Gabrielle Lyon discusses: - Why 25–40% of the weight lost on GLP-1 medications can be lean mass, and how to protect your muscle with adequate protein (1.2–1.5 g/kg) and resistance training - The GLP-1 fiber paradox and why these drugs need fiber to work, but make it hard to tolerate, and why 40–70% of patients hit GI side effects like bloating and consti

At 25, with zero rowing experience, Taryn Smith crossed the Atlantic alone. 3,000 miles, 46 days, and I learned that the fear was never the obstacle. It was the signal she was finally in the right place. In this episode, Dr. Gabrielle Lyon and Taryn Smith discuss: - Why fear is a "metric of success," not a stop sign, and how to train yourself to move toward discomfort instead of away from it - How food becomes visible performance fuel when you're the only engine, and how to preserve muscle on limited calories using protein and daily

Can GLP-1s Lower Your Libido?

A 28-pound weight loss is rarely the full story a patient brings into clinic. A 35-year-old woman: stable on an SSRI for postpartum anxiety, started on a GLP-1 for weight. No diabetes. No PCOS. The scale moved down. Her libido virtually disappeared. GLP-1s act on the same mesolimbic reward circuitry that governs appetite (PMID 42349741). In female rodents, they reduce sexual behavior (PMID 41653988). In women, no trial has measured it (PMID 42517362). One case doesn't prove cause. It proves the question is unanswered.

The standard was never perfection. It's preparation.

The best medicine doesn't just fix what's broken; it makes you harder to break. In this conversation with @drsusanmacdonald, the framing of patient care shifts entirely. Health isn't a fixed destination you arrive at and maintain forever. It's a waxing and waning course across a lifetime, shaped by the stress your body is put under and the life events that change your biology. Even after years of progress, a patient feeling great isn't cured. They're prepared. The clinical relationship is built on that understanding, which is why the first visit is about building trust, not handing over a pr

Does Creatine Help With Brain Fog and Memory in Perimenopause?

If you have walked into a room and forgotten why, or feel like the sharpness you used to count on is slipping, you are not imagining it. Before you pin all of it on hormones, here is where creatine fits. Creatine may play a role in brain health, not just muscle. The brain is metabolically expensive and runs on ATP, and creatine helps regenerate it. Supplementation does raise brain creatine, though modestly (PMID 38582412). There is some early evidence in the older population and women. Women take in less creatine from diet and have lower muscle stores; brain differences are subtler. A small

70 to 80% of Americans Have This in Their Body

70 to 82 percent of Americans have detectable glyphosate in their urine. Agricultural use has increased by more than 750 percent since 1996. Glyphosate functions like a low-grade selective antibiotic, targeting beneficial bacteria while sparing some harmful strains. However, we don’t yet know what that means for health outcomes. Some research suggests it may downregulate GLUT4 in skeletal muscle, the primary transporter for glucose uptake, potentially contributing to insulin resistance. You cannot change what agriculture is doing. You can change what you do.

Is Your Bread Really Harming You? The Truth About Glyphosate in Your Food | GLS #225

You've probably worried that the glyphosate on your bread is slowly harming you. The evidence points somewhere far less obvious and far more fixable. In this solo episode, Dr. Gabrielle Lyon discusses: - Why the real concern isn't cancer risk from your toast, but glyphosate's effect on your gut, where it can act like a selective antibiotic, hitting beneficial bacteria while sparing the harmful ones - Where the residue concentrates (grains and legumes like oats up to 1100 ppb) and why meat, milk, and eggs carry negligible amounts, so your organic dollars belong on oats and bread, not chicken -

Your future capacity is being built or eroded right now.

Every session you skip is a withdrawal from the physical capacity your future self depends on. Skeletal muscle atrophies without consistent stimulus. Adaptations built through resistance training compound across years into the metabolic health and functional independence that determine quality of life at 60, 70, and beyond. Every missed input is a regression. Your future capacity is being built or eroded right now.

Train hard. Eat with purpose. Show up.

Every training session, every gram in a protein-forward meal, and every hour of recovery you prioritize right now is a direct investment in the person you will be at 80. Skeletal muscle does not maintain itself, and bone density does not hold without load. The body you are building now is the one your future self will either be grateful for or limited by. There is no middle ground. Every session compounds while every missed opportunity counts. Train hard. Eat with purpose. Show up.

Jocko Willink: The One Habit That Changes Everything

There's one habit that touches your leadership, your relationships, your decisions, and your performance and most people never get around to it. In this conversation with @jockowillink, his answer is direct. Wake up early enough to get some form of physical activity done before your day starts. Ten minutes of burpees if that's all you have. The point isn't the duration or the modality. It's the sequence. Exercise before the day begins changes everything that follows. You show up sharper in meetings, interact better with people, make better decisions, and perform at a higher level across every

You Can't Out-Sleep A Broken Morning

You can't out-sleep a broken morning. Getting outside immediately after waking anchors your circadian rhythm, the 24-hour biological clock governing melatonin release and sleep drive. But consistent sleep and wake times make that system work. If you tend to stay up late, don't just decide your new bedtime is 10 pm. Commit to the same time every night and build from there. Sleep deprivation increases error rates and impairs decision-making in ways that compound across days. Anchor your morning in order to set up your night.

Do you finish a hard session and immediately sprint off to the next thing, treating recovery like an afterthought? Here's the problem with that: recovery doesn't happen just because the workout ended. Muscle adaptation needs specific building blocks, delivered consistently, in a window most people blow right past without realizing it. Protein is the foundation — that part isn't new. But the research keeps pointing to a few other names worth knowing: essential amino acids, HMB, and vitamin D, all shown to support muscle protein synthesis, slow down breakdown, and keep skeletal muscle function

Technology In Fitness Right Now is Valuable but still Cannot Replace this One Thing

EMS augments resistance training by stimulating muscle directly, helping you identify and feel which muscles are working. But it is not a substitute for the foundational work. Free weights and bands remain critical, particularly as we age.

Building muscle doesn't have to be complicated #musclebuilding #healthtips

Building a strong, capable body at any age isn't complicated. Most people just overcomplicate it. Consistency over duration, total body training three days a week, and a high-protein diet. That is the framework. First meal is a protein shake or eggs with Greek yogurt. Lunch is a smaller meal with at least 30 grams of protein. Dinner is a steak. No complicated protocols. Protein anchors every meal and training stays consistent. It is never too late to start building. Thank you to Fox and Friends for this opportunity.

Why You Can't Eat Red Meat Anymore

Same Burger. Two Different Outcomes. Here's Why. A steak at 7pm, an ER visit at 1am, a diagnosis of allergic reaction of unknown origin. That is the pattern behind alpha gal syndrome, one of the most significant immunology discoveries of the last two decades.

In this solo episode, Dr. Gabrielle Lyon discusses: Why alpha-gal reactions are delayed 2–6 hours after eating meat, and how that delay causes ER visits to be repeatedly misdiagnosed How your blood type changes your risk (type A and O are higher-risk; type B appears protected) and why a mismatched transfusion has proven fatal T

The truth about electrolyte replacement

Are you replacing water when you sweat but still hitting cramps, fatigue, and dizziness mid-session or in the heat? Sweat is not just water. It carries sodium and chloride, and losing too much disrupts fluid balance, nerve signaling, and muscle contraction. But not all cramps are from salt loss. Heat cramps respond to electrolytes. Exercise cramps in overworked muscles are from neuromuscular fatigue and respond better to stretching and ice. Heat illness is a spectrum. Heat cramps need rest and oral electrolytes. Heat exhaustion requires getting out of the heat, cooling down, and hydrating.

STOP Wasting Money on Skin Tightening

GLP-1 medications have revolutionized plastic surgery outcomes. The unintended consequences are only now becoming visible. Patients are losing more volume than intended, including in areas where fat preservation matters. When prior liposuction patients exhaust their remaining fat reserves, surgeons are sourcing cadaver-derived fat products, processed, irradiated, and washed of DNA to permit injection without rejection. In this episode with Kristy Hamilton, we cover what these downstream realities mean for body composition and the broader implications of fat loss without a plan to protect what

In this episode, Dr. Gabrielle Lyon sits down with Dr. Kristy Hamilton, a board-certified plastic surgeon, to discuss: Why rapid GLP-1 weight loss deflates facial volume and creates loose skin and why the leaner and more muscular you get, the more visible that laxity becomes The muscle-sparing br

One hour to build your own health is not optional

Why do the highest-performing people treat their health as optional when it is the biological infrastructure everything else depends on? Eight hours a day go to building someone else's outcome. The body carrying you through every one of those hours, absorbing the stress, maintaining focus, and sustaining output, gets whatever time is left. Skeletal muscle, metabolic health, and cardiovascular function are not separate from performance. They are what performance runs on. When those systems are consistently deprioritized, the decline is gradual and then it becomes impossible to ignore. One hou

Why is skeletal muscle called the organ of longevity?

Why is skeletal muscle called the organ of longevity, and what does that mean for how you should be approaching your health right now? In this conversation with Dr. Natalie Crawford, I explained that skeletal muscle functions as an endocrine organ. When it contracts, it secretes myokines, signaling proteins that travel to the brain, the ovaries, and the liver, creating inter-organ crosstalk that governs metabolism, hormonal balance, cognitive function, and inflammatory control. Most people have been conditioned to think about muscle as a cosmetic tissue, a vanity metric measured by appearance

Muscle breakdown vs. growth: The real science #gymscience #recovery

Are you training hard but still limping through the next four days wondering why your legs will not recover? Recovery does not happen because you finished the workout. Muscle adaptation requires the right signals and the right building blocks delivered at the right time. Essential amino acids are the specific compounds within protein that drive muscle protein synthesis, and research from the International Society of Sports Nutrition confirms they stimulate synthesis even at doses as small as 1.5 to 3 grams. HMB, a metabolite of leucine, adds a dual mechanism: it enhances muscle protein synthe

How Much Protein You Really Need After 40, According to the Science

What if the longevity movement is pulling the wrong lever and the people paying the price are the ones who can least afford it? The pathway the longevity world wants suppressed is the same one that builds and protects muscle. Protein raises IGF-1, but the primary driver is growth hormone, determined by genetics, age, sleep, and body composition. In insulin-resistant individuals, chronic high insulin from refined carbohydrates keeps bioavailable IGF-1 elevated constantly. The message to eat less protein is asking the people most likely to die of muscle loss to stop defending themselves. WATCH

Is Your Protein Aging You? What the Longevity Science Gets Wrong | GLS #219

Never Regret Being Strong

Start. Don't wait until you feel ready. The "feeling" of readiness is transient. Timing will never be perfect. If you wait until life slows down enough to prioritize yourself, that day rarely comes on its own. During my geriatric training, I learned that the people who built lasting strength never waited. They are the ones who decided that today was enough reason to begin. Remember, nobody ever regrets being strong. But everyone regrets waiting.

Could Your Pet Be Giving You Worms?

Why are parasitic infections widespread in the United States while remaining almost entirely undiagnosed, and what does that reveal about the current state of medicine? In this episode with Peter Jay Hotez, the answer is structural. Diagnostic tests for parasitic diseases lack funding. Specialty testing is not done routinely. Physicians often do not pursue it because the extra workload is significant. His hookworm vaccine targets the protein pathway the worm uses to degrade hemoglobin, inducing an antibody response, and may cost only two to three dollars per dose to produce. The science exist
