The Dr. Gabrielle Lyon Show

Can you tell someone's testosterone or estrogen levels just by looking at their face? Is "jawmaxxing" actually backed by science? In this video, we dive deep into the real science of hormones, physical attraction, and evolutionary biology. We debunk popular myths around high testosterone, facial masculinity, and ovulation preferences, revealing what the research actually shows about human mate selection. Discover why facial structure isn't a hormone panel, how estrogen impacts skin and collagen as women age, and why physical strength accounts for 70% of perceived bodily attractiveness. If you want to understand how hormones shape our development—and why muscle is the single most modifiable signal of health and longevity—this episode is for you.

When you have musculoskeletal pain, the natural instinct is to try and treat it directly. But the cause of that pain often starts somewhere else in the body. I learned that from this week's guest, Dr. JJ Thomas, who is my physical therapist and good friend. She was my patient first, and now we are each other's patients. She has practiced physical therapy for more than 25 years and has worked with the Philadelphia 76ers, the Philadelphia Eagles, and athletes from the UFC and US Olympic programs. What you'll learn in this episode: Why a chronic tendon injury can come right back, even after eccentric loading or PRP Whether a frozen shoulder in menopause is a hormone problem, and one of the first movements Dr. Thomas checks Why she works lying on her stomach, and the 10-minute band routine she wrote for an eight-hour desk day Why sitting up taller won't fix your posture, and what poor posture tells her about your body Why she gives patients shoulder blade exercises for their pelvic floor How much a standard…

Will I get too bulky?" No. "Is it too late?" Also no. Here's the context: during the menopause transition, women lose lean mass, gain fat, and their muscle becomes harder to build — the same workout and the same protein meal produce less than they did at 30. For years the only conversation has been hormone therapy, yes or no, as if that were the fix. In Part 2 of her menopause series, Dr. Gabrielle Lyon looks at what the evidence actually says builds muscle back. In this episode: -Postmenopausal women can build muscle and strength at any age (Frontiers in Endocrinology) - Up to 8 lbs of skeletal muscle in 12 weeks (J Nutr Health Aging RCT) - Anabolic resistance: why the same workout and the same meal produce less after menopause - "I was wrong": hormone therapy vs. lifting, and the conversations with Dr. Donald Layman - HRT alone and lean mass: a 0.06 kg difference across 12 trials - Estradiol plus training: bigger quad and fat-free mass gains, maintained at 12 months - Lift first — the practical translation…

Most patients are told one thing before surgery: stop all supplements. Duke surgeon Dr. Rebecca Knackstedt says that blanket advice can do harm, and that what you do in the days before surgery changes how you heal. Dr. Knackstedt is a plastic and reconstructive microsurgeon on faculty at Duke, an MD-PhD researcher and a certified functional medicine provider whose research focuses on surgical prehabilitation: preparing the body, mind, and home before surgery, the way we already do with rehab. In today’s episode, we discuss: • What prehab looks like for any operation • The labs she checks • Which supplements to keep and which to stop (omega-3s do not increase bleeding) • Hormones after breast cancer • Why mammograms still beat thermography • What chemo does to metabolism • The questions to ask your oncologist before a treatment decision • How much protein to eat (no standard exists, and the average woman gets 60 to 70 grams a day, well short of the 100-gram floor) • Why surgery is catabolic and muscle is your…

Menopause is changing your body, but the part nobody talks about isn't hot flashes. It's muscle. Women lose lean mass fastest in perimenopause, the loss probably starts closer to 35, and no pill, patch or injection fixes it. In this solocast, Dr. Gabrielle Lyon explains what estrogen, testosterone and FSH actually do to your metabolism, why a 50-year-old body can still build muscle, and the training and protein protocol to start now.

Your testosterone number matters at every age, but most men never learn what theirs should be. Mayo Clinic urologist Dr. Tobias Kohler explains why ~500 is the target, why 1,000 is already running hot, what 2,000+ does to the heart, and why a randomized trial found lifting without steroids beat steroids without lifting. Plus: the blood test that catches heart risk your cholesterol panel misses. Dr. Kohler returns for his second appearance (his first, on erections, testosterone and muscle mass, is one of the most-watched episodes in the show's history). This time: why men's longevity is roughly 50 years behind women's; the Princeton IV consensus he co-chaired, which treats ED as one of the strongest predictors of a future heart attack and points young men toward a coronary calcium scan; the 0–12 ceramide blood test that changes with your behavior; how to get a testosterone baseline that actually means something; what redlining to 2,000–3,000 does to the heart, the set point and the skin; Peyronie's disease,…

You say "steroids" and picture a baseball scandal, a jacked guy, a bad spray tan. But cortisol is a steroid. Estrogen is a steroid. The cream you put on poison ivy is a steroid. The word covering all of them is also covering testosterone therapy for women, and that collision is quietly costing women muscle and bone they don't have to lose. In this solo episode, prompted by a magazine interview on steroid use in women, Dr. Gabrielle Lyon breaks down what these molecules actually are, what they do inside a cell, and why the line between medicine and misuse has nothing to do with the word "steroid."

Most people assume becoming a parent is an emotional change, but a measurable part of it is hormonal, and it happens in fathers too. I sat down with Aldrich Chan, Psy.D., to talk about what changes in the brain, why the split we draw between mind and body does not hold up, and what decides whether stress reads as manageable or overwhelming when the hormones are identical either way.

You might think bone density is something you build slowly over a lifetime, but nearly all of your peak bone mass is set before age 18, in a four-year window most parents never see coming. In this solo episode I break down what happens to a child's skeleton during that window, what GLP-1 medications do inside a body that's still growing, and the protocol I'd want every parent to follow. Muscle and bone are not what a body has they're what a body was built to become. In this solo episode, Dr. Gabrielle Lyon breaks down the science of bone health in children, adolescent GLP-1 use, and muscle building in kids: Why the four years around age 12 in girls and 14 in boys account for close to 40% of the total bone mineral a person will carry for life Why a hip fracture in a healthy 29-year-old is almost always a story about a childhood building phase that never happened, often tied to a history of restriction like anorexia What semaglutide and other GLP-1 medications do inside a still growing skeleton, and why no…

You have probably been told that testosterone is a male hormone. Women produce more of it than estrogen, and for many of us it is the first hormone to go, sometimes reading zero five years before menopause while periods are still regular. Dr. Susan Hardwick-Smith and I get into what that costs you in muscle and bone, why there are thirty-one approved testosterone products for men and none for women, and what the number on your own lab report is measuring.

You probably ate something today with high protein printed across the front of it, and there is a good chance it did almost nothing for your skeletal muscle. There is no meaningful enforcement standard for what the front of a package is allowed to promise, and the research points to a per meal threshold most of these products do not come close to touching. Here is the number, the five myths that have to come off the table first, and how to read any label in about five seconds.

A Navy captain with 24 years of service went to medical for exhaustion, weight gain, and low mood, and was told to see a therapist and eat less. When he asked for a testosterone test his physician asked whether he had erectile dysfunction, and refused to order it when he said no. His level came back at 160; the cutoff we use in this country is 300. I've treated this population for 15 years, and roughly 27% of operators test below that number. Tim Parlatore is the attorney who wrote the Pentagon memo that now puts testosterone on the annual physical, and we get into what it says and why most men never have this hormone checked again after they leave pediatrics.

You might think creatine is a bodybuilder's steroid you have to cycle, load, and fear for your kidneys, but it's a compound your own body already makes from three amino acids, with one of the deepest safety records in all of nutrition science. The problem isn't the creatine; it's the noise around it. In this solo episode, Dr. Gabrielle Lyon discusses: Why the bump creatine causes in your creatinine lab value is a metabolic artifact, not a sign of kidney damage in healthy people Where the hair-loss fear came from. A single unreplicated study in one rugby player showing a 56% DHT rise, and why no research has ever directly linked creatine to hair loss How men and women respond differently (roughly 1.5 kg of lean mass in men vs. about a third of a kilogram in women), and why women still gain real strength, grip, cognition, and recovery Why you can't realistically eat your way to 5 grams a day: it would take 2.5 to 3 pounds of cooked meat and fish daily, so a single scoop closes the gap The protocol: 3–5 grams…

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 robs you of deep, restorative sleep The circadian "amplitude" formula for bright days and dark nights that predicts everything from menopause symptom severity to longevity, plus the ~90 minutes of natural light almost no one gets Why late-night eating rivals alcohol for damaging your resting physiology, and how a simple 12-hour eating window gets you most of the way there Why the fittest people sleep less, and how all-day…

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: dysbiosis, SIFO, repeated antibiotic use, and poorly controlled diabetes or fatty liver The three-part protocol to correct it, reduce the yeast burden, remove the carbohydrate fuel, and rebuild the microbiome, plus the carbohydrate challenge test, most doctors never run Why skeletal muscle is your body's primary site for clearing blood sugar, and how an under-muscled body drifts into the same insulin-resistant, dysbiotic state that…

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 solo pleasures don't stick if you're doing it alone, you're probably doing it wrong, and how enjoyment requires people plus memory How GLP-1s, SSRIs, and hormonal shifts can dull motivation, reward, and desire, and why knowing this gives you power over it Simple tech protocols: phone-free first hour, meals, and last hour that protect oxytocin, meaning, and connection Understand happiness as something you build rather than…

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 constipation When to fiber max vs. fiber mine, plus how to reintroduce fiber gradually so you get the gut benefits without the bloat, bezoars, or obstruction risk Get this balance right, and you keep your muscle, calm your gut, and let the medication do its job instead of ending up bloated, constipated, and quietly losing strength.

You'd think fear is what stops you from doing hard things. 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 amino acids The "long-term optimist, short-term realist" mindset that carries you through a slog with no end in sight The post-achievement crash nobody warns you about, and why the low after a big win is predictable Whether or not you'll ever touch an oar, you'll walk away with a portable mental framework for facing anything you've been avoiding, and a clearer sense of who you are when no one's watching.

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 The three NHANES analyses linking higher glyphosate to weaker grip strength and greater sarcopenia risk, and why protein and resistance training matter more than agonizing over parts per billion How switching to organic staples cuts urinary glyphosate by 71% in six days, and why "detox" products aren't the answer Why banning glyphosate isn't a clean win, the leading alternative, 2,4-D, was a component of Agent Orange…

Most people think low back pain means something is wrong with their back. It's usually the hips — and the fix often starts on your living room floor. In this episode, Dr. Gabrielle Lyon sits down with Dr. Kelly Starrett and Juliet Starrett, JD to discuss: Why 100% of the people who fly across the country to get a consult for stubborn low back pain are missing hip extension, and how to test yours with the couch stretch The "injury vs. incident" framework that tells you when pain needs a doctor and when you can manage it yourself How 20–30 minutes of floor sitting each evening restores the range of motion you thought you'd lost to age Why mobility is the missing third leg of the longevity triangle that roughly 90% of people skip By the end, you'll have a simple, no-equipment way to move without pain and keep the strength and mobility that let you do what you love as you age.

Over 500 published papers stand behind one of the internet's most popular peptides, but fewer than 30 of the humans studied are in them. Dr. Gabrielle Lyon separates the molecule from the marketplace so you can tell real evidence from good marketing. In this solo episode, Dr. Gabrielle Lyon discusses: Why BPC-157's "mountain of evidence" collapses to a 99.7% animal-to-human ratio - 544 papers, but fewer than 30 humans across three uncontrolled pilot trials How to place any peptide on the spectrum from FDA-approved (GLP-1s like semaglutide) to investigational to compounded, and why "GLP-1s work, so peptides work" is a trap What the FDA quietly did in April 2026, and why removing a dozen peptides from its safety-concern list was driven by policy pressure, not new safety data The 4 questions to run on any peptide before you inject level of evidence, what the study measured, where it's sourced from, and whether it's banned in tested sport Why the "boring work", resistance training, protein-anchored nutrition,…

Everyone on a GLP-1 is watching the scale; almost no one is watching their bones. Bone loss isn't an inevitable part of aging; it's a reversible signal that something deeper is going wrong, and it starts far earlier than most people are ever warned. In this episode, Dr. Gabrielle Lyon sits down with Dr. Douglas Lucas, a former Stanford-trained orthopedic surgeon turned bone-health specialist, to discuss: Why bone loss begins around 45 during perimenopause, not 50, and why waiting for your first DEXA scan at 65 is far too late to prevent it The blind spots in the standard DEXA scan: a scan-to-scan margin of error near 6% and no read on bone quality, only quantity Bone turnover markers (CTX and P1NP) you can test from blood to see whether you're building or breaking down bone in real time Why the "protein is bad for bones" and "alkalize your diet" beliefs are myths and why protein, minerals, and adequate calcium matter more than calcium alone What rebuilds bone at home: resistance training, real impact like…

You've eaten red meat your whole life, so why does a steak dinner suddenly leave you covered in hives at 1 AM? A single Lone Star tick bite can rewire your immune system into a delayed allergy to red meat, and most people (and even their doctors) never connect the two. 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 The simple alpha-gal IgE blood test to ask for, and what the numbers mean The hidden sources beyond food: gelatin, vaccines, heparin, thyroid meds, and even heart valves The tiered treatment approach that resolves symptoms in about 80% of patients on meat-avoidance alone Learn to recognize a condition that's increasingly common yet widely missed, so if it's happening to you, you'll know exactly what to test for and how to…

Everyone celebrates the weight GLP-1s take off, almost no one warns you about the volume they quietly pull out of your face and the loose skin you can't train away. The fix depends entirely on the diagnosis, and knowing which category your concern falls into is what saves you time, money, and regret. 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 breast augmentation (Preserve) that gets active women back to full training in about a week, and why placing an implant in front of the muscle protects your strength Which skin-tightening treatments reset structure (like internal radiofrequency) versus the surface treatments and "expensive coat rack" machines that won't touch real laxity The real NIH data on breast implant illness and why you don't need a $30,000 detox or…

The longevity world has convinced a generation of women that protein is shortening their lives. The science says they've got it backwards and the people hurt most are the ones who need protein most. In this episode, Dr. Gabrielle Lyon breaks down the protein-and-longevity fear, steelmans the strongest case against protein, then walks through what the evidence shows: The RDA (0.8 g/kg) is a deficiency floor, not a target, the intake one camp calls "dangerously high" is what federal guidelines and expert groups now recommend (1.2–1.6 g/kg) The IGF-1–cancer link is tiny (a 3–11% risk bump vs. smoking's 1,000–2,000%), and the IGF-1–mortality curve is U-shaped: the lowest levels carry ~40% higher death risk Sarcopenia roughly doubles death risk (3.5× with frailty) and perimenopause stacks anabolic resistance on top, exactly when women are told to fear the foods that defend them By the end, you'll understand the mTOR and IGF-1 science well enough that nobody online can scare you off your own dinner, plus a simple…

The parasites most Americans think of as a tropical problem are already here; showing up as fatigue, asthma, and gut issues that standard tests keep calling "normal." An estimated 1 in 20 people may carry one and never know it. In this episode, Dr. Gabrielle Lyon sits down with Dr. Peter Hotez, a tropical-medicine physician and vaccine scientist, to discuss: Why toxocariasis, a worm shed by household dogs and cats, may affect 5–6% of the U.S. population, with larvae migrating through the lungs and brain Why standard PCR panels come back negative and which specific tests (antibody, fecal, eosinophil count) to ask for How to lower your risk at home, from deworming pets on a vet schedule to knowing which symptoms warrant a targeted test Why the popular "worm therapy for autoimmune disease" idea has the relationship backwards, worms are a leading driver of IBD and asthma, not a cure Whether you've been told your labs are fine but still feel off, this conversation gives you a clear, evidence-based framework for…

You might think microplastics are just an environmental nuisance that passes through your body, but the latest tissue studies tell a very different story. As a physician, Dr. Gabrielle Lyon breaks down where the science lands, past both the fear-mongering and the dismissiveness. In this solo episode, Dr. Gabrielle Lyon discusses: Why over 58% of patients in a landmark NEJM study had plastic embedded in their arterial plaque and the 4.5x higher risk of heart attack, stroke, and death that came with it How microplastics act as a "Trojan horse," carrying endocrine-disrupting chemicals into your blood, testes, brain, and reproductive tissue Why perimenopause and menopause are an especially vulnerable window for plastic-driven hormone disruption The five low-cost "Lyon Protocol" rules to cut your exposure, starting with never microwaving plastic and letting food cool before you store it This matters because you don't need to overhaul your life or wait twenty years for perfect data to protect your cellular health;…

You've been told that 10,000 steps a day is enough to keep you healthy but when it comes to your bones and your muscles, walking falls short, and the science explains exactly why. The real drivers of strength, bone density, and lasting health are load, intensity, and resistance, not just movement. In this episode, Dr. Gabrielle Lyon sits down with Dr. Alyssa Olenick, a PhD in exercise metabolism and ultramarathoner who blends endurance and strength training, to discuss: Why the "interference effect," the fear that cardio cancels your strength gains, is overblown for almost everyone, and what causes the carryover fatigue How most women train too lightly, believing they're at a 9 out of 10 when they're closer to a 5, and never trigger real muscle adaptation Why estrogen is not the primary driver of muscle, resistance training is, and what that means through the menopause transition The early warning signs of low energy availability, including cycle changes that show up long before a missed period, and the…

You were told your testosterone is "normal" so why do you still feel exhausted, weak, and off? The number on your lab report was never built for you, and your own genetics may be the reason it doesn't match how you feel. In this solo episode, Dr. Gabrielle Lyon discusses: Why the standard 300–1000 ng/dL range ignores your age, comorbidities, and genetics, and why two men with identical labs can feel completely different How CAG repeats determine whether your body "catches" the testosterone you produce, meaning you might need 400 to feel great while someone else needs 800 Why the 80-year-old fear that testosterone fuels prostate cancer is built on a single flawed 1941 study, and what the androgen saturation model proves instead How everyday endocrine disruptors BPA in receipts, phthalates in personal care, atrazine in tap water quietly lower your testosterone even when you eat clean and train hard The correct AUA testing protocol your doctor may be skipping: two early-morning, fasted measurements plus actual…

The July Forever Strong Foundations Challenge begins July 6, 2026. This 4-week challenge is designed to help you build a stronger, more energized you through sustainable nutrition, training, and lifestyle habits. Register here: https://bit.ly/4gCmoNR For 40 years you've been told 0.8 grams of protein per kilogram is "enough" but the scientists who contributed the reports behind the new 2025–2030 Dietary Guidelines say not a single study has ever shown that number beats eating more. In this episode, Dr. Gabrielle Lyon sits down with Dr. Don Layman and Dr. Heather Leidy, the protein researchers who developed the scientific reports informing the new U.S. Dietary Guidelines, to discuss: Why the guidelines reprioritized protein to a healthy range of 1.2–1.6 g/kg and why that still isn't technically "high protein" Why you don't really have a protein requirement, but an essential amino acid requirement and what that means for your brain, mood, and antioxidant production Who's quietly falling short: roughly 20% of…

The receptor that switches off your appetite on a GLP-1 drug is the same one wired into your reward circuitry, your hormones, and your blood vessels, which means when you turn down hunger, something else may be getting turned down too, and for most people taking these drugs, nobody ever checked. In this solo episode, Dr. Gabrielle Lyon discusses: Why the same drug class can improve sexual function in men with obesity while potentially dampening it in lean or postmenopausal women — and why the deciding factor isn't the drug, it's the body How rapid weight loss raises SHBG, the protein that soaks up free testosterone, so a "normal" total testosterone result can hide a real deficit your bloodwork won't flag Why women make up 60–70% of GLP-1 prescriptions yet the entire evidence base for female sexual function is two case reports, with zero validated questionnaires in any pivotal trial The three-tier action plan for anyone on or about to start a GLP-1 — baseline your sexual function first, get free testosterone…

You might think more cardio is the key to aging well but Lisa Smith-Batchen, who has run 135 miles through Death Valley ten times, says it's strength that actually carries you through the decades. In this episode, Dr. Gabrielle Lyon sits down with Lisa Smith-Batchen, one of the most decorated ultra-endurance athletes in American history and a 10-time Badwater 135 finisher, to discuss: Why being strong matters more than being fast and why "it's not the running that helps me run, it's being strong" The first movement everyone should train at any age: sit to stand, followed by squats, wall sits, lunges, and pushups Why cutting protein after 60 backfires, and why Lisa fuels on roughly 80% protein calories during races How to start lifting late, her 85-year-old client went from 5-pound weights to 230-pound farmer carries The fall that ended her father's life, and why "pick your feet up" became her mission for aging athletes You'll walk away with a clear, muscle-first blueprint for staying strong, mobile, and…

Most men think erectile dysfunction is a bedroom problem and low testosterone is just a fact of getting older. This roundtable makes the case that both are early warning lights for your heart, your metabolism, and your long-term health and that ignoring them can cost you a decade. In this episode, Dr. Gabrielle Lyon sits down with urologists and men's health specialists Dr. Mohit Khera, Dr. Larry Lipshultz, and Dr. Tobias Köhler to discuss: Why a 35-year-old with ED carries a ~15% risk of heart attack or stroke within 7 years, ~3.5x the risk of depression, and ~30% odds of diabetes or prediabetes and why a prescription alone misses all of it Why "age-related" testosterone decline is largely a misnomer: a healthy man shouldn't drop significantly with age, so falling T usually signals something reversible underneath How testosterone became the single best blood marker of a man's overall health, and the case for annual screening that almost no man gets What the TRAVERSE trial changed when the FDA removed…

Most men think erectile dysfunction is a bedroom problem. It's actually one of the earliest warning signs of cardiovascular disease, capable of showing up three to five years before a heart attack. In this episode, Dr. Gabrielle Lyon sits down with Dr. Amy Pearlman, a urologist trained in men's sexual health, to discuss: Why ED is a symptom of vascular health, not a standalone disease and how the artery feeding the heart is roughly double the size of the one feeding the penis, so problems show up "down there" first Why "normal" testosterone can be meaningless, and the questions to ask before accepting a lab result that didn't flag How daily erections preserve penile tissue the way water keeps a sponge supple and why disuse can cost noticeable size over just a few months That cardiovascular exercise can rival ED medication for improving erectile function, making your heart health the real fix How to track erectile fitness before there's a problem, instead of waiting until something breaks By the end, you'll…

Most people think the cholesterol number on their lab report tells them whether their heart is at risk. But former National Lipid Association President Dr. Kevin Maki explains that LDL is just one piece of a much bigger picture and focusing on it alone can mean missing the markers that matter most. In this episode, Dr. Gabrielle Lyon sits down with Dr. Kevin Maki, former President of the National Lipid Association and co-editor-in-chief of the Journal of Clinical Lipidology, to discuss: Why ApoB and Lp(a) are better predictors of heart risk than LDL and why only about 2% of people ever get Lp(a) tested What a beef-vs-chicken feeding study revealed about red meat and cholesterol (the LDL results came back identical at 112 mg/dL) The evidence behind the seed oil debate, including why higher linoleic acid levels tracked with lower inflammation markers across a 2,000-person dataset Why the balance of cholesterol-raising and cholesterol-lowering foods matters more than saturated fat alone The simple "ABCs"…

Colorectal cancer is now the leading cancer killer in adults under 50, and patients in their 20s are presenting with metastatic disease that has nothing to do with family history. Most physicians are still telling young patients with rectal bleeding that it's probably just hemorrhoids and that's costing lives. In this episode, Dr. Gabrielle Lyon sits down with Dr. Michelle Pearlman, a board-certified gastroenterologist and founder of a Miami-based gastro-metabolic clinic, to discuss: The specific warning signs every adult under 50 should never ignore, regardless of age including rectal bleeding, unintentional weight loss, and persistent abdominal pain Why GLP-1 medications like Ozempic and Zepbound are being miscategorized as weight loss drugs when they're actually metabolic reprogrammers with applications in fatty liver, sleep apnea, and inflammation The protein, fiber, and resistance training protocol Dr. Pearlman uses to protect muscle mass in patients on GLP-1 therapy How hormone replacement therapy…

Most parents are quietly paving the road their kids were supposed to learn to walk on by themselves and Jocko Willink has spent 20 years watching what happens when that road is too smooth. In this episode, Dr. Gabrielle Lyon sits down with Jocko Willink, retired Navy SEAL commander, founder of Echelon Front, and bestselling author of Extreme Ownership and Discipline Equals Freedom, to discuss: Why the "apex parent / apex kid" mindset is a quiet trap, and what to do instead of paving the road How nature vs nurture actually plays out and what you can and cannot shape in your child The one trait Jocko wants his kids to inherit (and why every virtue becomes a vice when pushed to the extreme) The lie that successful, high-functioning people tell themselves about wanting more The single most important trait of a great leader and the one habit Jocko says will make every other part of your life better starting tomorrow You'll walk away with a clearer operating system for the kind of parent, leader, and person you…

Most men don't know they have a pelvic floor, and most doctors aren't trained to look for dysfunction in it. The result: testicles are being surgically removed for pain that's actually neuropathic, at double the rate of a far more effective nerve-sparing procedure. In this episode, Dr. Gabrielle Lyon sits down with Dr. Susan Macdonald, a board-certified urologist, surgical program director at Penn State, and one of only ~30 U.S. specialists treating chronic pelvic pain in men, to discuss: Why "prostatitis" is often the wrong diagnosis, and how rounds of antibiotics mask the real problem The male pelvic floor anatomy almost no medical school teaches, and how to recognize dysfunction in yourself or a patient Off-label medications (Cymbalta, gabapentin, amitriptyline) that are quietly transforming chronic pelvic pain treatment Why erectile dysfunction is rising sharply in teenagers, and the role pornography plays in rewiring young brains Who actually qualifies for a penile implant, and what the surgery really…

Most people are chasing the wrong version of strength and paying for it with pain, poor movement, and a body that breaks down faster than it should. In this episode, Dr. Gabrielle Lyon sits down with Mark Bell, elite powerlifter, entrepreneur, and founder of Slingshot, to discuss: Why strength training is essential at every age but most people are defining "strength" too narrowly How modern life has created an "exercise deficiency," and why artificial exercise is the only fix The truth about fat, protein, and the biggest nutrition mistakes holding people back from lasting weight loss The emerging peptide and drug landscape, and what it means for the future of health optimization Why forcing your kids to move isn't cruelty, it's one of the most protective things you can do as a parent Whether you're 25 or 75, this episode will challenge how you think about movement, muscle, and what it actually means to be strong physically and mentally.

We are living through one of the most significant shifts in medicine in generations, and most people don’t fully understand what it means. Dr. Christle Guevarra joins me to zoom out on the entire GLP-1 landscape; from the drug’s origins as a modest diabetes treatment in 2005 to today’s third-generation medications still moving through clinical trials, and what all of it means for the future of obesity, performance, and longevity. 🙌Thank you to our sponsors: 🌍 Cozy Earth - Go to https://bit.ly/4teXQhz for up to 20% off! 🤍 Timeline - Get 20% off your Mitopure order at https://www.timeline.com/lyon 🚲 Carol Bike - Visit https://bit.ly/4tg4cxa and use code LYON for $100 off your CAROL Bike Explore More from Dr. Gabrielle Lyon: Premium Podcast Subscription: Ad-free episodes, key takeaway summaries, exclusive Q&A, and behind-the-scenes content https://foreverstrong.supercast.com Weekly newsletter: Recipes, podcast updates, and practical weekly insights https://drgabriellelyon.com/sign-up/ Apply to become a patient:…

The moment you decide to show up publicly, you open the door to opinions from people who would never say those things to your face. Dominique Sachse, journalist, author, and content creator who has lived her life on camera for over three decades, gets honest about what it costs to put yourself out there, why online cruelty is a psychology problem more than a content problem, and how “Teflon Dom” developed the thick skin to let none of it redirect her.

Only nine scientists were asked to advise on the 2025 Dietary Guidelines for Americans, and Dr. Tom Brenna was one of them. In this conversation, he pulls back the curtain on how dietary guidelines are actually made, why the process has never been the same twice, and what it was like to watch a decades-old saturated fat recommendation get carried forward despite a lack of evidence supporting it at the level of total mortality. This is the dietary guidelines conversation the internet has been missing: straight from someone who was actually in the room. Want ad-free episodes?

In a world flooded with conflicting health advice, how do you actually figure out what’s true? Dr. David Allison, one of the most rigorous scientific minds in obesity and nutrition research, shared the exact framework he uses to evaluate evidence, from peer-reviewed trials to podcast recommendations to AI-generated summaries. He explains the difference between trusting science as a process and trusting individual studies, why most nutrition epidemiology functions more like advertising than research, and how ordinary people can build a reliable filter for health claims without a PhD.

Up to 70% of dementia may be preventable, so why aren’t more people talking about what actually drives cognitive decline? In this episode, I’m with Dr. Tommy Wood, neuroscientist and author of “The Stimulated Mind,” to explore the lifestyle levers that protect your brain across a lifetime.

Metabolic flexibility is your body’s ability to efficiently burn fat or carbohydrate depending on demand, may be one of the most important and least understood markers of long-term health. In this episode, I’m with Dr. Martin Gibala to explore the emerging science of Fat Max, why mitochondrial quality is central to both performance and longevity, and how sprint interval training produces comparable mitochondrial adaptations to traditional endurance work in a fraction of the time. Could the key to better metabolic health be less about the hours you log and more about how hard you’re willing to push? Want ad-free episodes?

The most decorated woman in motorsports history will tell you she feared losing far more than she loved winning, and that fear is exactly what drove her to the top. In this episode, I’m with racing legend Danica Patrick to unpack the psychology of elite performance, from the “blind faith” that carried her through two decades of racing to the nervous system conditioning she built starting at age 10. What would be possible for you if you learned to channel pressure instead of escaping it? Want ad-free episodes?

In this episode of The Dr. Gabrielle Lyon Show, Dr. Gabrielle Lyon sits down with Dr. Michael Eisenberg, Director of Male Reproductive Health at Stanford University and Chief Medical Advisor of SwimClub, to break down what truly determines sperm health and reproductive success. They discuss: How metformin, GLP-1 medications, testosterone therapy, and anabolic steroids affect male fertility Why sperm count is a powerful biomarker for long-term health and longevity The role of sleep, muscle mass, exercise, diet, marijuana, and environmental toxins like microplastics Whether platelet-rich plasma, or PRP, can help severe male infertility Daily habits that quietly reduce a couple’s chances of conceiving If you care about fertility, hormones, metabolic health, or the future of men’s health, this conversation is essential.
