Detoxes. Seed oils. Cortisol making you fat. Artificial sweeteners causing weight gain. Insulin as the root of obesity. Hormones as the master switch for fat loss. These ideas keep spreading — even among smart, educated people who should know better. In this episode, Dr. Layne Norton explains why. This is not just another myth-busting list. It’s a breakdown of the psychology, incentives, and media dynamics that make fitness misinformation so sticky. Layne covers why the human brain was not built for science, why anecdotes beat statistics, why fear sells better than nuance, how algorithms reward certainty and outrage, and why intelligence does not protect you from bias. You’ll also get a practical toolkit for evaluating claims: what questions to ask, which red flags matter, how the hierarchy of evidence actually works, and why the “big rocks” of health still outperform the latest viral villain. If you’ve ever wondered why bad fitness ideas travel faster than good evidence, this episode is the map. #LayneNorton #FitnessMisinformation #EvidenceBasedFitness #NutritionScience #Biolayne #SeedOils #ArtificialSweeteners #CriticalThinking #HealthMyths #DrLayneNortonPodcast SPONSORS • REPS Research Review: https://biolayne.com/reps • Team Biolayne – One-On-One Coaching: https://biolayne.com/online-coaching LAYNE'S COMPANIES Carbon Diet Coach: https://joincarbon.com/podcast Outwork Nutrition: https://outworknutrition.com REPS Research Review: https://biolayne.com/reps Workout Builder: https://biolayne.com/workout-builder Team Biolayne: https://biolayne.com/online-coaching Physique Coaching Academy: https://physiquecoachingacademy.com FOLLOW LAYNE http://www.facebook.com/laynenorton http://www.twitter.com/biolayne http://www.instagram.com/biolayne TIMESTAMPS 0:00:00 - Intro 0:01:37 - The Misinformation Epidemic 0:08:14 - Human Brains Were Not Designed For Science 0:26:01 - The Power of Anecdotes 0:36:17 - Fear as a Marketing Tool 0:41:04 - Social Media and the Algorithm 0:48:01 - Why Smart People are Vulnerable 0:58:30 - The Business of Misinformation 1:03:16 - How Science Actually Works 1:08:48 - A Toolkit for Evaluating Claims 1:15:20 - Conclusion: The Big Rocks Matter Most 1:17:28 - Outro SHOW NOTES https://biolayne.com/podcasts/dr-layne-norton-podcast/the-science-of-fitness-misinformation-why-smart-people-believe-dumb-things-episode-37

In this listener Q&A, Dr. Layne Norton answers your most-asked questions on training, fat loss, genetics, recovery, and how to cut through the noise — with his kitten Wheezy as co-host. Topics covered in this episode: • Training to failure — is it more important for advanced lifters than beginners? • Muscle confusion — why constantly changing exercises creates the illusion of progress (and how much variety is actually useful) • Muscle mass and longevity — is there a point where more muscle stops helping, and why extreme muscularity can look like a U-shaped curve • “I barely eat anything but I’m not losing weight” — why feelings aren’t data, food volume vs calorie density, and why one week of tracking changes everything • Ultra-processed foods — do they cause more fat gain than minimally processed foods when calories are matched? • Metabolic adaptation — how reversible is it, what’s transient vs what’s tied to lost lean mass, and what happens if you stay at the new body weight • How to know who to trust — look for nuance, people who change their minds, logical consistency, and those who haven’t made a diet their identity • Smartwatch recovery scores & HRV — why you should not change your training based on a single day’s number • “Do I have bad genetics?” — Layne’s 10-year answer, chicken-leg-to-world-record-squat story, and the motto “let’s find out” • What Layne loves (and hates) most about his job And more! Whether you’re stuck on fat loss, second-guessing your program, or tired of conflicting advice, this episode gives practical, no-BS takeaways you can use. #BioLayne #LayneNorton #QandA #AMA #EvidenceBasedNutrition #TrainingToFailure #MetabolicAdaptation #FatLoss #MuscleBuilding #Genetics #HRV SPONSORS • Physique Coaching Academy - Advanced Coaching and Nutrition Education for Personal Trainers: https://physiquecoachingacademy.com • Workout Builder – Customized training programs for all experience levels: https://biolayne.com/workout-builder LAYNE'S COMPANIES Carbon Diet Coach: https://joincarbon.com/podcast Outwork Nutrition: https://outworknutrition.com REPS Research Review: https://biolayne.com/reps Workout Builder: https://biolayne.com/workout-builder Team Biolayne: https://biolayne.com/online-coaching Physique Coaching Academy: https://physiquecoachingacademy.com FOLLOW LAYNE http://www.facebook.com/laynenorton http://www.twitter.com/biolayne http://www.instagram.com/biolayne TIMESTAMPS 0:00:00 - Intro 0:00:55 - Training to Failure 0:02:58 - Muscle Confusion 0:05:06 - Muscle Mass for Longevity 0:07:05 - Physique Coaching Academy 0:08:06 - Hard Time Losing Weight 0:09:48 - Processed Food 0:11:24 - Metabolic Adaptation 0:12:58 - Who to Trust 0:18:55 - Wearables 0:21:13 - Workout Builder 0:22:08 - Good Genetics 0:27:02 - Love/Hate Most About My Job 0:30:17 - Training Evolution 0:32:55 - Quitting vs Letting Go 0:35:55 - Outro SHOW NOTES https://biolayne.com/podcasts/dr-layne-norton-podcast/ama-06-weight-loss-genetics-muscle-confusion-who-to-trust-and-more-episode-36

In the second installment of the Overrated/Underrated series, Dr. Layne Norton ranks the most talked-about muscle-building strategies as overrated, underrated, or properly rated — based purely on the evidence. No hype. No bro-science. Just what the data actually says about what builds muscle, what doesn’t, and what’s been oversold. Layne covers training intensity, proximity to failure, volume, rep ranges, range of motion, exercise selection, muscle confusion, protein timing, post-workout nutrition, and more! He also explains why he recently changed his mind on calorie surplus, why most people are not training as close to failure as they think, and why stretch/lengthened-position tension matters more than most lifters realize. Whether you’re a coach, athlete, or just trying to build muscle efficiently, this episode cuts through the noise so you can stop wasting time on the overrated stuff and double down on what actually moves the needle. #musclebuilding #hypertrophy #evidencedbasedfitness #DrLayneNorton #Biolayne SPONSORS • Workout Builder – Customized training programs for all experience levels: https://biolayne.com/workout-builder • Outwork Nutrition - Evidence-Based Supplements to Support Your Hard Work: https://outworknutrition.com LAYNE'S COMPANIES Carbon Diet Coach: https://joincarbon.com/podcast Outwork Nutrition: https://outworknutrition.com REPS Research Review: https://biolayne.com/reps Workout Builder: https://biolayne.com/workout-builder Team Biolayne: https://biolayne.com/online-coaching Physique Coaching Academy: https://physiquecoachingacademy.com FOLLOW LAYNE http://www.facebook.com/laynenorton http://www.twitter.com/biolayne http://www.instagram.com/biolayne TIMESTAMPS 0:00:00 - Intro 0:00:43 - Training Intensity 0:05:34 - Training to Failure 0:07:04 - Training Volume 0:09:07 - Rep Ranges 0:12:19 - Workout Builder 0:13:16 - Range of Motion 0:15:31 - Exercise Selection 0:18:02 - Muscle Confusion 0:19:29 - Tempo 0:20:54 - Training Frequency 0:22:13 - Protein Intake 0:22:54 - Carbohydrates 0:24:12 - Outwork Nutrition 0:25:39 - Fats 0:27:02 - Calorie Surplus 0:27:36 - Protein Timing 0:28:38 - Protein Quality 0:30:12 - Recomposition 0:32:15 - Post-Workout Nutrition 0:33:28 - Creatine 0:35:19 - Testosterone Boosters 0:35:51 - Outro SHOW NOTES https://biolayne.com/podcasts/dr-layne-norton-podcast/overrated-underrated-muscle-building-edition-episode-35

In this episode of the Dr. Layne Norton Podcast, Layne sits down with renowned researcher and ketogenic diet expert Dr. Dominic D’Agostino to dive deep into the science of the ketogenic diet. Professor Dominic D’Agostino (University of South Florida Morsani College of Medicine / Institute for Human and Machine Cognition) is one of the leading voices on nutritional ketosis, exogenous ketones, and metabolic therapies. Together, they unpack what the research actually shows about keto – beyond the hype and social media claims. They cover the mechanisms of ketosis, potential therapeutic applications (including epilepsy, metabolic health, neurological conditions, and ongoing research areas like cancer support), practical considerations for implementing a well-designed ketogenic approach, common misconceptions, protein and micronutrient needs, exogenous ketones, and how keto stacks up for fat loss, performance, and long-term adherence compared to other dietary strategies. Expect an evidence-based, no-BS conversation that prioritizes data over dogma. #KetogenicDiet #Keto #DominicDAgostino #LayneNorton #NutritionScience #MetabolicHealth #EvidenceBasedNutrition #DrLayneNortonPodcast SPONSORS • David Protein - Buy 4 cartons, get 1 FREE at: https://davidprotein.com/pages/layne • REPS Research Review: https://biolayne.com/reps LAYNE'S COMPANIES Carbon Diet Coach: https://joincarbon.com/podcast Outwork Nutrition: https://outworknutrition.com REPS Research Review: https://biolayne.com/reps Workout Builder: https://biolayne.com/workout-builder Team Biolayne: https://biolayne.com/online-coaching Physique Coaching Academy: https://physiquecoachingacademy.com FOLLOW LAYNE http://www.facebook.com/laynenorton http://www.twitter.com/biolayne http://www.instagram.com/biolayne TIMESTAMPS 0:00:00 - Intro 0:02:37 - Dom's Background 0:05:57 - Ketones and Seizures 0:15:23 - Animal Research 0:18:42 - David Protein 0:20:17 - Mechanisms of Ketone Therapy 0:28:07 - Magnesium 0:29:12 - Dementia/Alzheimers 0:37:55 - Cancer 0:45:38 - REPS Research Review 0:46:29 - Cancer Cont. 1:16:50 - Muscle Hypertrophy 1:27:55 - Fasting 1:38:33 - Training 2:01:42 - Ranking Importance 2:04:34 - Last Question 2:20:13 - Outro SHOW NOTES https://biolayne.com/podcasts/dr-layne-norton-podcast/the-ketogenic-diet-with-dr-dominic-dagostino-episode-34

In this episode, I sit down with Dr. Mike Ormsbee, Director of the Institute of Sports Science and Medicine at Florida State University. Mike is one of the sharpest, most pragmatic researchers in the field — a former hockey player turned leading expert on exercise, nutrition, fat metabolism, sleep, and performance. We had an absolute blast geeking out for nearly two hours. Mike and I share very similar backgrounds (athletes who got into lifting and science for selfish reasons — getting jacked and lean), and it shows in how practical and grounded this conversation is. What we covered: • Mike’s journey from competitive ice hockey and early bodybuilding days to becoming a professor and running one of the top sports nutrition labs in the country • Resistance training vs. endurance exercise for fat metabolism (what the cellular data actually shows) • Mechanisms vs. real-world outcomes in fat loss • Pre-sleep nutrition: Does eating protein (or anything) before bed ruin fat loss, sleep, or recovery? • Interpreting science, research biases, publication issues, and why “what works for you” still matters We also had some friendly disagreement on collagen, which I think you’ll really enjoy. If you want evidence-based, no-BS discussion on training, nutrition timing, supplements, and how to actually apply the science to real life (whether you’re an athlete or just trying to stay healthy and jacked), this one is for you. #DrLayneNorton #MikeOrmsbee #SportsNutrition #ResistanceTraining #PreSleepProtein #Collagen #FatMetabolism #EvidenceBasedFitness SPONSORS • Outwork Nutrition - Evidence-Based Supplements to Support Your Hard Work: https://outworknutrition.com • Workout Builder – Customized training programs for all experience levels: https://biolayne.com/workout-builder LAYNE'S COMPANIES Carbon Diet Coach: https://joincarbon.com/podcast Outwork Nutrition: https://outworknutrition.com REPS Research Review: https://biolayne.com/reps Workout Builder: https://biolayne.com/workout-builder Team Biolayne: https://biolayne.com/online-coaching Physique Coaching Academy: https://physiquecoachingacademy.com FOLLOW LAYNE http://www.facebook.com/laynenorton http://www.twitter.com/biolayne http://www.instagram.com/biolayne TIMESTAMPS 0:00:00 - Intro 0:02:47 - Mike's Background 0:06:12 - The Start of Resistance Training Research 0:10:38 - Fat Metabolism 0:17:35 - Lipolysis vs Fat Loss 0:21:40 - Outwork Nutrition 0:23:08 - Research Considerations 0:28:45 - Hard Training Above All 0:33:16 - Risk Probabilities 0:35:10 - Sleep Nutrition Research 0:44:06 - Workout Builder 0:45:02 - Sleep Nutrition Research Cont. 0:45:50 - Practical Takaways 0:47:30 - Performance Outcomes 0:49:07 - Study Design Evolution 0:52:06 - Wearables 0:56:51 - Missing Sleep and Sleep Schedules 1:07:31 - Training or Competing at Night 1:11:11 - Nutrient Timing 1:18:01 - Carbs and Exercise Performance 1:31:27 - Collagen 1:42:47 - Research Discussion 1:49:46 - Final Question 1:59:47 - Outro SHOW NOTES https://biolayne.com/podcasts/dr-layne-norton-podcast/sports-nutrition-performance-with-mike-ormsbee-episode-32

In this episode, Dr. Layne Norton delivers a comprehensive, evidence-based breakdown of metabolic adaptation — one of the biggest reasons why fat loss slows down and maintaining weight loss feels so difficult. Layne explains exactly what metabolic adaptation is, how it affects every major component of energy expenditure (BMR, NEAT, exercise energy expenditure, and TEF), and the powerful neuroendocrine and behavioral changes that create an “energy gap” driving weight regain from both sides of the calorie equation. He also covers the under-discussed adaptations in hunger hormones (leptin, ghrelin, GLP-1, PYY, CCK, etc.), brain responses to food, adipose tissue changes that favor fat storage, and whether rapid refeeding can increase fat cell number. The episode finishes with practical, research-backed strategies to minimize these adaptations and common myths (including whether “starvation mode” is real). Whether you’re currently cutting, planning a fat loss phase, or struggling with weight maintenance, this episode will give you a clear scientific understanding of what’s happening in your body and how to work with these adaptations more effectively. #MetabolicAdaptation #WeightLossScience #FatLoss #TDEE #BMR #NEAT #Leptin #Ghrelin #DietBreaks #EvidenceBasedNutrition #DrLayneNorton #Biolayne #NutritionScience SPONSORS • Carbon Diet Coach – 14 day free trial: https://joincarbon.com/podcast • Team Biolayne – One-On-One Coaching: https://biolayne.com/online-coaching LAYNE'S COMPANIES Carbon Diet Coach: https://joincarbon.com/podcast Outwork Nutrition: https://outworknutrition.com REPS Research Review: https://biolayne.com/reps Workout Builder: https://biolayne.com/workout-builder Team Biolayne: https://biolayne.com/online-coaching Physique Coaching Academy: https://physiquecoachingacademy.com FOLLOW LAYNE http://www.facebook.com/laynenorton http://www.twitter.com/biolayne http://www.instagram.com/biolayne TIMESTAMPS 0:00:00 - Intro 0:02:50 - What is Metabolic Adaptation 0:06:18 - Components of TDEE 0:12:38 - BMR 0:27:22 - NEAT 0:31:10 - Exercise Expenditure 0:34:44 - TEF 0:35:16 - Leptin and Appetite 0:36:35 - Hormones 0:42:05 - Changes to the Brain 0:49:36 - The Energy Gap 0:50:17 - Changes to Adipose Tissue 0:57:44 - Rapid Regain After Weight Loss 1:03:04 - How to Minimize Metabolic Adaptation 1:10:57 - Myths 1:15:48 - Outro SHOW NOTES https://biolayne.com/podcasts/dr-layne-norton-podcast/metabolic-adaptation-episode-31

In this listener Q&A, Layne dives deep into your most-asked questions on supplements, protein sources, cholesterol, weight-loss medications, and more. As always, he breaks down the actual research and gives no-BS, evidence-based takeaways you can actually use. Topics covered in this episode: • Creatine HCl – Supplementing with which form of creatine (hydrochloride vs others)? What does the research actually show? • David Protein Bars – Thoughts on the lawsuit and bars failing label tests (lawsuit update included) • Plant proteins & amino acids – Do they really miss certain essential amino acids? Should it fully count toward your total daily protein intake? • Ashwagandha safety – Should you be worried about liver toxicity? • Collagen supplements – Benefits for tendons, joints, injury recovery, and connective tissue (even if it’s not great for muscle building) • Dietary fiber – Why it’s important for health and practical ways to get more (supplements vs whole foods) • LDL cholesterol – Oxidized LDL and particle size: what actually matters and why the debate exists • GLP-1 medications – Are they just a “quick fix”? Willpower, muscle loss concerns, and what happens with weight regain after stopping • And more! Whether you’re optimizing your supplement stack, navigating plant vs animal protein debates, or curious about the latest on GLP-1s and cholesterol, this episode delivers clear, science-backed answers. #BioLayne #LayneNorton #QandA #AMA #EvidenceBasedNutrition #Creatine #PlantProtein #Ashwagandha #Collagen #DietaryFiber #LDLCholesterol #GLP1 #Ozempic #NutritionScience SPONSORS • Team Biolayne – One-On-One Coaching: https://biolayne.com/online-coaching • REPS - Research Explained in Practical Summaries: https://biolayne.com/reps LAYNE'S COMPANIES Carbon Diet Coach: https://joincarbon.com/podcast Outwork Nutrition: https://outworknutrition.com REPS Research Review: https://biolayne.com/reps Workout Builder: https://biolayne.com/workout-builder Team Biolayne: https://biolayne.com/online-coaching Physique Coaching Academy: https://physiquecoachingacademy.com FOLLOW LAYNE http://www.facebook.com/laynenorton http://www.twitter.com/biolayne http://www.instagram.com/biolayne TIMESTAMPS 0:00:00 - Intro 0:00:39 - Creatine HCL 0:06:24 - David Protein Lawsuit 0:10:59 - Team Biolayne Coaching 0:11:50 - Plant Protein Amino Acids 0:14:24 - Plant Protein Total Protein Intake 0:16:43 - Ashwagandha Liver Toxicity 0:19:10 - Collagen 0:25:16 - Fiber 0:34:19 - REPS Research Review 0:35:09 - LDL Cholesterol 0:47:29 - GLP1's 0:57:04 - Outro SHOW NOTES https://biolayne.com/podcasts/dr-layne-norton-podcast/ama-05-creatine-plant-protein-collagen-fiber-glp1s-and-more-episode-30

In this deep dive episode, Dr. Layne Norton breaks down everything you need to know about protein — from the molecular level to practical real-world application. We cover: • What protein actually is, how it’s made and broken down in the body • The complete science of muscle protein synthesis (MPS) and muscle protein breakdown (MPB), including the critical roles of mTORC1, leucine, eIF4E, 4E-BP1, and more • How dietary protein is digested, absorbed, and used by your muscles • Why leucine content matters and how different protein sources (whey vs. wheat vs. collagen) dramatically affect MPS • The “muscle full effect,” protein thresholds by age, and why protein distribution across meals may (or may not) matter • How high-protein diets impact fat loss, satiety, energy expenditure, and long-term body composition • The truth about protein and health outcomes: mortality, cardiovascular disease, cancer, kidney function, and type 2 diabetes — with the latest evidence separated from the hype and confounding factors Whether you’re a casual gym-goer, competitive athlete, bodybuilder, powerlifter, or just someone who wants to optimize muscle and health, this episode gives you the complete, evidence-based picture on protein intake, quality, timing, and safety. Plus, tips for vegans and how to actually use this information day-to-day. If you want to understand protein at a level most people (and even many coaches) never reach, this is the episode for you! #Protein #MuscleProteinSynthesis #HighProteinDiet #LayneNorton #EvidenceBasedNutrition #BodybuildingScience #FatLoss #MuscleBuilding SPONSORS • Outwork Nutrition - Evidence-Based Supplements to Support Your Hard Work: https://outworknutrition.com • David Protein - Buy 4 cartons, get 1 FREE at: https://davidprotein.com/pages/layne LAYNE'S COMPANIES Carbon Diet Coach: https://joincarbon.com/podcast Outwork Nutrition: https://outworknutrition.com REPS Research Review: https://biolayne.com/reps Workout Builder: https://biolayne.com/workout-builder Team Biolayne: https://biolayne.com/online-coaching Physique Coaching Academy: https://physiquecoachingacademy.com FOLLOW LAYNE http://www.facebook.com/laynenorton http://www.twitter.com/biolayne http://www.instagram.com/biolayne TIMESTAMPS 0:00:00 - Intro 0:01:20 - Protein Chemistry Overview 0:16:15 - Outwork Nutrition 0:17:43 - Protein Digestion and Absorption 0:21:17 - How Protein Affects Muscle 0:37:00 - David Protein 0:38:35 - Protein Distribution 0:43:05 - Protein and Fat Loss 0:48:09 - Protein and Mortality 0:50:32 - Protein and Cardiovascular Disease 0:52:06 - Protein and Cancer 0:53:32 - Protein and Kidney Disease 0:56:38 - Protein and Type 2 Diabetes 0:57:53 - Recommendations 1:06:53 - Outro SHOW NOTES https://biolayne.com/podcasts/dr-layne-norton-podcast/protein-deep-dive-episode-29

Are seed oils (and the polyunsaturated fats they contain) quietly destroying your health… or is the outrage mostly hype and misinformation? In this deep-dive episode, Dr. Layne Norton cuts through the noise with a comprehensive, evidence-first breakdown of the science on seed oils, linoleic acid (LA/PUFA), saturated fat, LDL/ApoB, oxidation, inflammation, and cardiovascular outcomes. Layne directly addresses the most common claims made by the anti-seed-oil crowd and shows why the totality of high-quality evidence—from mechanistic studies to randomized controlled trials and Mendelian randomization—supports replacing saturated fat with polyunsaturated fats from seed oils for better metabolic and heart health. What’s covered in this episode: • ApoB & LDL oxidation myth: Why PUFA-enriched LDL is more prone to oxidation per particle, but why that actually misses the bigger picture (lower LDL-P/ApoB, better clearance, less overall atherogenic burden in the arterial wall) • Human RCTs: A balanced review of the major trials (Minnesota Coronary Experiment, Sydney Diet Heart, LA Veterans, Oslo Diet-Heart, Finnish Mental Hospital, STARS, etc.)—including their real strengths, weaknesses, trans-fat confounds, and what the data actually show when you filter properly • Mendelian Randomization evidence: Why lifelong lower LDL/ApoB causally reduces CVD risk regardless of how it’s lowered, and why ApoB/LDL particle number is the key driver (not just LDL-C) • The Linoleic Acid (LA) hypothesis: Does more LA → more arachidonic acid → more inflammation, T2D, CVD, and cancer? Layne examines the actual human data on tissue levels, prostaglandin synthesis, systemic inflammation markers, insulin sensitivity, and disease outcomes • Seed oil processing & refining: Hexane, neutralization, bleaching, deodorization—why the “chemical” scare tactics don’t hold up, peroxide/anisidine values actually drop during refining, and why the final product is far safer and cleaner than the fear-mongering suggests • Naturalistic fallacy & miscellaneous claims: Why “our ancestors didn’t eat seed oils” isn’t a compelling argument, plus other common talking points Whether you’re team butter, team vegetable oil, or just tired of the tribal nutrition wars, this episode gives you the full context and references so you can make up your own mind based on science instead of social media soundbites. #SeedOils #PUFA #HeartHealth #Cholesterol #EvidenceBased #LayneNorton #NutritionScience #SaturatedFat #LinoleicAcid #CardiovascularHealth SPONSORS • David Protein - Buy 4 cartons, get 1 FREE at: https://davidprotein.com/pages/layne • Carbon Diet Coach – 14 day free trial: https://joincarbon.com/podcast LAYNE'S COMPANIES Carbon Diet Coach: https://joincarbon.com/podcast Outwork Nutrition: https://outworknutrition.com REPS Research Review: https://biolayne.com/reps Workout Builder: https://biolayne.com/workout-builder Team Biolayne: https://biolayne.com/online-coaching Physique Coaching Academy: https://physiquecoachingacademy.com FOLLOW LAYNE http://www.facebook.com/laynenorton http://www.twitter.com/biolayne http://www.instagram.com/biolayne TIMESTAMPS 0:00:00 - Intro 0:02:21 - Personal Bias 0:03:42 - Arguments Against Seed Oils 0:05:33 - Fatty Acid Structure 0:08:31 - Prostaglandin Pathway 0:09:09 - Current Health Advice 0:10:03 - LDL Cholesterol 0:12:42 - Specific Question 0:13:57 - Human Trials 0:16:10 - David Protein 0:17:45 - Sydney Heart Study 0:22:22 - Minnesota Coronary Experiment 0:25:09 - Rose Corn Oil Trial 0:27:29 - LA Veterans Study 0:29:20 - Finnish Mental Hospital Study 0:31:51 - STARS 0:33:48 - Carbon Diet Coach 0:34:48 - Analysis of Human RCTs 0:35:57 - Mendelian Randomization 0:44:15 - LDL Cholesterol and ApoB 0:51:49 - Oxidation 0:58:54 - Linoleic Acid 1:02:02 - Seed Oil Processing 1:10:06 - Frying in Seed Oils 1:10:54 - Naturalistic Fallacy 1:13:11 - Summary SHOW NOTES https://biolayne.com/podcasts/dr-layne-norton-podcast/seed-oils-the-evidence-based-deep-dive-episode-28

In this episode, Dr. Layne Norton interviews Professor Jeremy Loenneke — one of the world’s top researchers on blood flow restriction training. They break down how BFR actually works, why metabolite accumulation appears to be the primary driver of its muscle-building effects, practical self-application techniques, and whether expensive cuffs are even necessary. Jeremy also shares his latest thinking on the hypertrophy vs. strength relationship, why muscle may be an underrated health marker (just like fat once was), his biggest concerns about the replication crisis in exercise science, and how he responds to critics who call BFR “gimmicky.” Whether you’re an athlete chasing gains, a coach, or just training smarter, this is a must-listen deep dive into the science and real-world application of BFR.

It’s here—the last episode of Dr. Layne Norton’s no-nonsense supplement series! In this finale, Layne takes a hard, evidence-based look at some of the most overhyped supplements in fitness and bodybuilding. He cuts through the marketing claims, examines the actual research, and tells you exactly what works, what doesn’t, and who (if anyone) should actually be spending money on these products. In this episode, Layne covers: BCAAs – Do they build muscle, boost strength, or speed recovery more than just eating enough total protein?HMB – Why the “like deca” claims from the ’90s never panned out, and what it actually does (and doesn’t) doGlutamine & Arginine – Poor bioavailability, gut-first metabolism, and why they rarely deliver the muscle-building or performance benefits promisedEcdysterone & Turkesterone – The “natural steroid” hype meets high-quality human RCTsElectrolytes – When they actually matter (and when plain water is sufficient)“Better” Creatine forms (CEE, buffered creatine, HCl, etc.) vs. good old Creatine Monohydrate – spoiler: you’re usually just paying 2–4× more for the same (or worse) results Layne breaks down the bold claims vs. reality for each supplement, explains what the science shows they actually do in the body, and identifies the very narrow populations who might see real benefit. Stop wasting money on supplements that underdeliver. Focus on what actually moves the needle.
