World's Leading Protein Scientist Reveals How Much You Actually Need for Healthy Aging
Professor Stuart Phillips, a leading protein researcher with 400+ scientific papers, challenges common protein misconceptions in this ZOE podcast. He explains that most people aren't protein deficient, despite marketing claims on processed foods. Phillips recommends 1.0-1.2g per kg body weight for healthy adults, higher than current guidelines but far below the 2g/kg often promoted by fitness influencers. Key insights include: protein serves as structural building blocks (unlike carbs/fats which are fuel), muscle acts as the body's only protein storage, and adequate intake becomes crucial after age 30 when muscle loss begins. He emphasizes that resistance exercise, not just protein, is essential for muscle maintenance. The discussion covers protein's role in immune function, why plant proteins aren't inferior to animal sources, and how the body adapts to lower protein intake through nitrogen balance.
