View the Show Notes Page for This Episode Become a Member to Receive Exclusive Content Sign Up to Receive Peter’s Weekly Newsletter In this “Ask Me Anything” (AMA) episode, Peter explores how to determine the right diet for yourself rather than searching for a universal “best” diet. He begins by laying out five non-negotiable criteria that any sustainable eating pattern must meet—energy balance, metabolic health, adequate protein, micronutrient sufficiency, and long-term adherence—before introducing a practical rubric for evaluating different diets. Using this framework, Peter walks through the ketogenic, carnivore, vegan, and Mediterranean diets, highlighting their strengths, ideal candidates for each, and common pitfalls such as micronutrient gaps or adherence challenges. He explains why this guidance is aimed at people who feel overwhelmed by diet choices, not zealots defending a single approach, and provides practical advice on using tools like DEXA scans, lab markers, continuous glucose monitors, and symptom tracking to assess whether a diet is truly working.
