Today's episode features Dr. Carlene Starck, a nutrition scientist whose groundbreaking research is changing the way we think about protein and amino acid requirements. Her work suggests that current recommendations for essential amino acids may be far too low, with major implications for fat loss, muscle preservation, and how we define protein quality.

NEW! I love Puori for their pure, science-backed supplements. Creatine+ is one of my top recommendations for women, as it's a foundational supplement that supports fat loss, body recomposition, lean muscle, and even cognition. Get 20% off at puori.com/VANESSA

We discuss her research on:

• Why true protein and amino acid needs are higher than guidelines suggest

• How this widens the gap between animal and plant-based proteins

• The impact of gut and oxidative amino acid losses on protein requirements

• Novel strategies to improve protein digestion, from kiwifruit enzymes to keratin hydrolysates

• Dairy vs. plant alternatives, and what her latest A2 milk study revealed about mood and cognition

• Affordable ways to close key nutrient gaps for better body composition and health

Dr. Starck also shares a preview of her upcoming work on protein requirements and what it means for the future of nutrition science.

This is a must-listen episode if you want to understand why protein is so central to fat loss, metabolic health, and long-term body recomposition.
