In this episode of "On Purpose," Jay Shetty interviews Dr. Giles Yeo, a geneticist, about diet myths and the science of weight loss. Dr. Yeo argues that focusing solely on calorie counting is misleading because the quality of food matters more than the quantity. He explains how the body processes different macronutrients (fats, carbs, and proteins) and how factors like food processing and genetics influence weight gain. They discuss practical strategies for healthier eating, such as prioritizing protein and fiber while limiting free sugars, and how to interpret food labels effectively. Dr. Yeo also addresses the role of genetics in predisposing individuals to weight gain and the importance of behavioral changes and building muscle mass for long-term health. The conversation also touches on the use of weight loss drugs like Ozempic, emphasizing they should be used for health reasons rather than cosmetic purposes.
