Hunger Signals with Dr. Jason Fung - Epsiode 2786

In this episode of Fitness Confidential, host Vinny Tortorich welcomes Dr. Jason Fung, nephrologist and author of the new book *The Hunger Code*, to dissect the root causes of overeating and obesity. The conversation dismantles the outdated 'calories in, calories out' model, arguing instead that hunger is driven by complex hormonal systems—homeostatic, hedonic, and conditioned—rather than simple math. Fung explains how ultra-processed foods hijack these systems, creating relentless cravings and food noise, while natural, whole foods trigger satiety and restore balance. He critiques the overreliance on GLP-1 drugs like Ozempic, warning they act as a temporary crutch that dulls life’s pleasures and leads to rebound weight gain when discontinued. Fung emphasizes that sustainable weight loss requires addressing the underlying hunger mechanisms through diet and lifestyle, not pharmaceutical shortcuts. The episode also touches on the dangers of food industry manipulation, the futility of trendy supplements, and the importance of trusting time-tested whole foods over experimental peptides and synthetic solutions.
