Description: 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/
