What if the reason fat loss feels impossible is not willpower, not discipline, and not “eat less, move more” but your hormones, your hunger, and your body’s fat thermostat?
In this episode of The Ben Azadi Show, Ben welcomes back Dr. Jason Fung to break down why most weight loss advice fails long term and why obesity and type 2 diabetes are not calorie problems, they are hormonal problems. Dr. Fung explains how insulin acts as a fat storage signal, why fasting insulin and C-peptide can reveal metabolic dysfunction years before A1c rises, and how hunger is the real problem behind overeating. He also introduces key ideas from his new book, The Hunger Code, including the fat thermostat, the “three whys,” and the three types of hunger: physical, emotional, and conditioned. You will walk away with a clearer framework for sustainable fat loss that works with human physiology instead of fighting it.
