Dr. Don Layman | Everything Protein: Optimal Intake for Muscle & Health | July 12, 2026 | Ep. 74

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.
