Summary:Dr. Don Layman breaks down optimal protein intake, leucine, and muscle health, including protein timing, aging, and metabolic health.Dr. Layman, one of the world’s leading researchers on protein metabolism, joins Max Helmer (The Low Carb Consultant) to explain how much protein you really need, why leucine is a key trigger for muscle protein synthesis, and how protein intake changes with age. He contrasts protein quality from plant vs. animal sources, clarifies the science on “too much protein” and kidney health, and explains why muscle should be viewed as an organ of longevity.Dr. Layman also covers the best timing and dosing of protein after exercise, how protein supports injury recovery, and what current dietary guidelines get wrong about protein, carbs, and fat. He discusses how food industry influence shapes public nutrition advice and what that means for anyone trying to improve metabolic health on a low-carb or higher-protein diet.If you want an evidence-based framework for protein intake for athletes, older adults, fat loss, or general health, this conversation with Dr. Layman provides clear targets and practical examples you can apply to your own nutrition.Find Dr. Layman:Site: https://www.metabolictransformation.comX: https://x.com/donlayman?lang=enInsta: https://www.instagram.com/layman.don/Key topics:Protein requirements and mythsRole of leucine in muscle synthesisProtein quality: plant vs. animalTiming of protein intake post-exerciseOverconsumption of protein and kidney healthProtein and injury recoveryDietary guidelines and food industry influenceMuscle as an organ of longevityProtein for older adultsImpact of diet on metabolic healthChapters:00:00 Introduction to Dr. Donald Layman and his research01:21 How Dr. Layman got into protein research03:00 Common misconceptions about protein intake03:59 Understanding the RDA for protein and its limitations05:54 Factors influencing optimal protein intake06:47 Differences between plant and animal protein quality09:09 Protein intake post-exercise: does timing matter?10:58 Maximum safe protein intake and overconsumption myths15:18 Protein and muscle building in older adults36:17 The significance of leucine in muscle synthesis44:10 The role of supplements versus food for amino acids55:15 Thoughts on carnivore and low-carb diets01:01:21 Dietary strategies for muscle preservation and aging01:15:54 Optimal meal timing and distribution for muscle health01:25:02 Practical tips to improve health with diet changesKeywords:protein, leucine, muscle health, aging, nutrition, dietary guidelines, protein quality, exercise, supplements, health tips
