I am delighted to reconnect with Dr. Jason Fung today. He is a trained nephrologist and world-leading expert on intermittent fasting and metabolic health. He has authored multiple books, including the New York Times best-seller, The Obesity Code, The Diabetes Code, and, more recently, The Hunger Code.   In our conversation today, we unpack the obsessive focus on the calories-in, calories-out model, which is neither practical nor effective. We explore the root causes behind the narrow-minded thinking that calories alone drive obesity, differences between types of hunger and conditioned responses, how hormones affect other hormones, and lessons about GLP-1s. We examine the critical importance of fiber and protein, and offer clarity around carbohydrates. We also cover the impact of meal timing, sleep, and circadian biology, the fat thermostat and sympathetic tone, nutrition, stress, and mindful eating, and dive into the issue of ultra-processed foods. Join us for an insightful conversation that challenges conventional wisdom and offers a nuanced and sustainable approach to understanding hunger, metabolism, and long-term health. IN THIS EPISODE, YOU WILL LEARN: “Calories in, calories out” framework is technically correct, but practically useless How the homeostatic, hedonic, and conditioned hunger types differ Dr. Fung shares his take on GLP-1 medications How fiber stimulates natural GLP-1 production Processed and natural carbohydrates produce vastly different glucose and insulin responses.
