Most Replayed Moment: Calories In, Calories Out Is A Myth! Why Most Diets Fail - Dr. Jason Fung

In this episode, Steven Bartlett interviews Dr. Jason Fung about the misconceptions surrounding obesity and weight loss, particularly the "calories in, calories out" model. Dr. Fung argues that this model is overly simplistic and doesn't account for hormonal responses, especially insulin's role in fat storage and burning. He explains how dieting can lower metabolism, leading to yo-yo effects, and contrasts this with intermittent fasting, which can help maintain or even increase metabolic rate by allowing insulin levels to fall and the body to access stored fat. Dr. Fung also addresses the limited impact of exercise on weight loss compared to diet, emphasizing that the type and timing of food intake are crucial for hormonal balance and effective weight management. He shares his experience as an early proponent of intermittent fasting, the resistance he faced, and the physiological basis for its benefits, highlighting the importance of viewing food as instructions to the body rather than just energy.
