Jason Fung’s The Hunger Code presents a provocative argument about food, hunger and body weight. Rather than viewing weight primarily as a simple matter of calories consumed and calories burned, Fung places considerable emphasis on insulin, hormones, hunger and the timing of eating.
Fasting is central to this argument. Fung suggests that periods without food can change the hormonal environment in the body and make it easier for the body to use stored energy. He also connects fasting with broader ideas about metabolic health and, ultimately, longevity.
