Why a 575-Pound Man Had Perfect Metabolic Labs – Craig Emmerich

In this episode of The Feldman Protocol, can individual biology shape whether a given diet or protocol actually works — or does one approach fit everyone? Craig Emmerich (co-author and nutrition researcher alongside Maria Emmerich) makes the case for bioindividuality in metabolic health, discussing his decade-long journey with chronic Lyme disease and ankylosing spondylitis, the protein-sparing modified fast as a weight-loss tool, a fat-cell–centric view of insulin resistance, oxidative priority of fuel sources, and whether AI may reshape personalized medicine.
