The Dr. Layne Norton Podcast

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 #BiolayneSPONSORS• 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.comLAYNE'S COMPANIESCarbon Diet Coach: https://joincarbon.com/podcastOutwork Nutrition: https://outworknutrition.comREPS Research Review: https://biolayne.com/repsWorkout Builder: https://biolayne.com/workout-builderTeam Biolayne: https://biolayne.com/online-coachingPhysique Coaching Academy: https://physiquecoachingacademy.comFOLLOW LAYNEhttp://www.facebook.com/laynenortonhttp://www.twitter.com/biolaynehttp://www.instagram.com/biolayneTIMESTAMPS0:00:00 - Intro0:00:43 - Training Intensity0:05:34 - Training to Failure0:07:04 - Training Volume0:09:07 - Rep Ranges0:12:19 - Workout Builder0:13:16 - Range of Motion0:15:31 - Exercise Selection0:18:02 - Muscle Confusion0:19:29 - Tempo0:20:54 - Training Frequency0:22:13 - Protein Intake0:22:54 - Carbohydrates0:24:12 - Outwork Nutrition0:25:39 - Fats0:27:02 - Calorie Surplus0:27:36 - Protein Timing0:28:38 - Protein Quality0:30:12 - Recomposition0:32:15 - Post-Workout Nutrition0:33:28 - Creatine0:35:19 - Testosterone Boosters0:35:51 - OutroSHOW NOTEShttps://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 #DrLayneNortonPodcastSPONSORS• David Protein - Buy 4 cartons, get 1 FREE at: https://davidprotein.com/pages/layne• REPS Research Review: https://biolayne.com/repsLAYNE'S COMPANIESCarbon Diet Coach: https://joincarbon.com/podcastOutwork Nutrition: https://outworknutrition.comREPS Research Review: https://biolayne.com/repsWorkout Builder: https://biolayne.com/workout-builderTeam Biolayne: https://biolayne.com/online-coachingPhysique Coaching Academy: https://physiquecoachingacademy.comFOLLOW LAYNEhttp://www.facebook.com/laynenortonhttp://www.twitter.com/biolaynehttp://www.instagram.com/biolayneTIMESTAMPS0:00:00 - Intro0:02:37 - Dom's Background0:05:57 - Ketones and Seizures0:15:23 - Animal Research0:18:42 - David Protein0:20:17 - Mechanisms of Ketone Therapy0:28:07 - Magnesium0:29:12 - Dementia/Alzheimers0:37:55 - Cancer0:45:38 - REPS Research Review0:46:29 - Cancer Cont.1:16:50 - Muscle Hypertrophy1:27:55 - Fasting1:38:33 - Training2:01:42 - Ranking Importance2:04:34 - Last Question2:20:13 - OutroSHOW NOTEShttps://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 mattersWe 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 #EvidenceBasedFitnessSPONSORS• 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-builderLAYNE'S COMPANIESCarbon Diet Coach: https://joincarbon.com/podcastOutwork Nutrition: https://outworknutrition.comREPS Research Review: https://biolayne.com/repsWorkout Builder: https://biolayne.com/workout-builderTeam Biolayne: https://biolayne.com/online-coachingPhysique Coaching Academy: https://physiquecoachingacademy.comFOLLOW LAYNEhttp://www.facebook.com/laynenortonhttp://www.twitter.com/biolaynehttp://www.instagram.com/biolayneTIMESTAMPS0:00:00 - Intro0:02:47 - Mike's Background0:06:12 - The Start of Resistance Training Research0:10:38 - Fat Metabolism0:17:35 - Lipolysis vs Fat Loss0:21:40 - Outwork Nutrition0:23:08 - Research Considerations0:28:45 - Hard Training Above All0:33:16 - Risk Probabilities0:35:10 - Sleep Nutrition Research0:44:06 - Workout Builder0:45:02 - Sleep Nutrition Research Cont.0:45:50 - Practical Takaways0:47:30 - Performance Outcomes0:49:07 - Study Design Evolution0:52:06 - Wearables0:56:51 - Missing Sleep and Sleep Schedules1:07:31 - Training or Competing at Night1:11:11 - Nutrient Timing1:18:01 - Carbs and Exercise Performance1:31:27 - Collagen1:42:47 - Research Discussion1:49:46 - Final Question1:59:47 - OutroSHOW NOTEShttps://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 #NutritionScienceSPONSORS• Carbon Diet Coach – 14 day free trial: https://joincarbon.com/podcast• Team Biolayne – One-On-One Coaching: https://biolayne.com/online-coachingLAYNE'S COMPANIESCarbon Diet Coach: https://joincarbon.com/podcastOutwork Nutrition: https://outworknutrition.comREPS Research Review: https://biolayne.com/repsWorkout Builder: https://biolayne.com/workout-builderTeam Biolayne: https://biolayne.com/online-coachingPhysique Coaching Academy: https://physiquecoachingacademy.comFOLLOW LAYNEhttp://www.facebook.com/laynenortonhttp://www.twitter.com/biolaynehttp://www.instagram.com/biolayneTIMESTAMPS0:00:00 - Intro0:02:50 - What is Metabolic Adaptation0:06:18 - Components of TDEE0:12:38 - BMR0:27:22 - NEAT0:31:10 - Exercise Expenditure0:34:44 - TEF0:35:16 - Leptin and Appetite0:36:35 - Hormones0:42:05 - Changes to the Brain0:49:36 - The Energy Gap0:50:17 - Changes to Adipose Tissue0:57:44 - Rapid Regain After Weight Loss1:03:04 - How to Minimize Metabolic Adaptation1:10:57 - Myths1:15:48 - OutroSHOW NOTEShttps://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 #NutritionScienceSPONSORS• Team Biolayne – One-On-One Coaching: https://biolayne.com/online-coaching• REPS - Research Explained in Practical Summaries: https://biolayne.com/repsLAYNE'S COMPANIESCarbon Diet Coach: https://joincarbon.com/podcastOutwork Nutrition: https://outworknutrition.comREPS Research Review: https://biolayne.com/repsWorkout Builder: https://biolayne.com/workout-builderTeam Biolayne: https://biolayne.com/online-coachingPhysique Coaching Academy: https://physiquecoachingacademy.comFOLLOW LAYNEhttp://www.facebook.com/laynenortonhttp://www.twitter.com/biolaynehttp://www.instagram.com/biolayneTIMESTAMPS0:00:00 - Intro0:00:39 - Creatine HCL0:06:24 - David Protein Lawsuit0:10:59 - Team Biolayne Coaching0:11:50 - Plant Protein Amino Acids0:14:24 - Plant Protein Total Protein Intake0:16:43 - Ashwagandha Liver Toxicity0:19:10 - Collagen0:25:16 - Fiber0:34:19 - REPS Research Review0:35:09 - LDL Cholesterol0:47:29 - GLP1's0:57:04 - OutroSHOW NOTEShttps://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 factorsWhether 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 #MuscleBuildingSPONSORS• 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/layneLAYNE'S COMPANIESCarbon Diet Coach: https://joincarbon.com/podcastOutwork Nutrition: https://outworknutrition.comREPS Research Review: https://biolayne.com/repsWorkout Builder: https://biolayne.com/workout-builderTeam Biolayne: https://biolayne.com/online-coachingPhysique Coaching Academy: https://physiquecoachingacademy.comFOLLOW LAYNEhttp://www.facebook.com/laynenortonhttp://www.twitter.com/biolaynehttp://www.instagram.com/biolayneTIMESTAMPS0:00:00 - Intro0:01:20 - Protein Chemistry Overview0:16:15 - Outwork Nutrition0:17:43 - Protein Digestion and Absorption0:21:17 - How Protein Affects Muscle0:37:00 - David Protein0:38:35 - Protein Distribution0:43:05 - Protein and Fat Loss0:48:09 - Protein and Mortality0:50:32 - Protein and Cardiovascular Disease0:52:06 - Protein and Cancer0:53:32 - Protein and Kidney Disease0:56:38 - Protein and Type 2 Diabetes0:57:53 - Recommendations1:06:53 - OutroSHOW NOTEShttps://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 pointsWhether 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 #CardiovascularHealthSPONSORS• David Protein - Buy 4 cartons, get 1 FREE at: https://davidprotein.com/pages/layne• Carbon Diet Coach – 14 day free trial: https://joincarbon.com/podcastLAYNE'S COMPANIESCarbon Diet Coach: https://joincarbon.com/podcastOutwork Nutrition: https://outworknutrition.comREPS Research Review: https://biolayne.com/repsWorkout Builder: https://biolayne.com/workout-builderTeam Biolayne: https://biolayne.com/online-coachingPhysique Coaching Academy: https://physiquecoachingacademy.comFOLLOW LAYNEhttp://www.facebook.com/laynenortonhttp://www.twitter.com/biolaynehttp://www.instagram.com/biolayneTIMESTAMPS0:00:00 - Intro0:02:21 - Personal Bias0:03:42 - Arguments Against Seed Oils0:05:33 - Fatty Acid Structure0:08:31 - Prostaglandin Pathway0:09:09 - Current Health Advice0:10:03 - LDL Cholesterol0:12:42 - Specific Question0:13:57 - Human Trials0:16:10 - David Protein0:17:45 - Sydney Heart Study0:22:22 - Minnesota Coronary Experiment0:25:09 - Rose Corn Oil Trial0:27:29 - LA Veterans Study0:29:20 - Finnish Mental Hospital Study0:31:51 - STARS0:33:48 - Carbon Diet Coach0:34:48 - Analysis of Human RCTs0:35:57 - Mendelian Randomization0:44:15 - LDL Cholesterol and ApoB0:51:49 - Oxidation0:58:54 - Linoleic Acid1:02:02 - Seed Oil Processing1:10:06 - Frying in Seed Oils1:10:54 - Naturalistic Fallacy1:13:11 - SummarySHOW NOTEShttps://biolayne.com/podcasts/dr-layne-norton-podcast/seed-oils-the-evidence-based-deep-dive-episode-28
