Listen Now

Unpack protein like never before in Episode #290, a compilation of the most insightful conversations with nutrition experts to dissect the multifaceted role of protein in our diets. From the fundamentals of protein needs and muscle synthesis to the nuanced interplay between protein intake and longevity, this masterclass is your one-stop shop to understand how protein truly impacts our health and wellbeing.

“I think one can be healthy with really quite a wide range of protein [amount].” – Dr Donald Layman

Today’s masterclass features an assembly of leading nutrition experts: Donald Layman, Christopher Gardner, Stuart Phillips, Valter Longo, Mark Messina, and Fritz Horstmann. Their combined expertise spans the breadth of protein research, from muscle health to dietary impacts on longevity. Collectively, they deliver a wealth of knowledge, cutting through the complexity to provide clear, authoritative insights on protein’s vital role in our health.

“Everything matters, but certainly if you look at the studies the proteins and the amino acids are playing the key role.” – Dr Valter Longo

This episode centres around the impact of protein on bodies, consolidating the latest research for a well-rounded view of protein consumption. We dissect the nuances of protein nutrition, from Don Layman’s insights on protein quality and timing to Valter Longo’s research on protein fasting and its effects on aging. We also explore Stuart Phillips’ and Christopher Gardner’s perspectives on daily protein requirements, Mark Messina’s clarification of soy’s health effects, and Fritz Horstmann’s application of protein in plant-based diets for muscle building.
