The Obesity Code
Fung reframes weight gain around insulin, meal timing, refined foods, and hormonal signals rather than simple moral failure.
Core idea.
The book’s practical thesis is that the body responds to hormonal context. Food quality, refined carbohydrates, meal frequency, sleep, stress, and fasting windows all change the signal environment.
