The Obesity Code: Unlocking the Secrets of Weight Loss

Fri, 24 Jul 2026 00:00:00 +0000

For thirty years the advice never changed: eat less, move more. Count your calories, cut your fat, and the weight will come off. It didn’t. Jason Fung’s argument is that this failed because the premise itself is wrong. Obesity is not a problem of too many calories and too little willpower. It is a hormonal disorder, and the hormone that runs it is insulin. Insulin is your body’s fat-storage signal. When it stays high, your body locks fat away and keeps it there, no matter how carefully you ration your plate. The way out is not to eat less of everything. It is to lower insulin, mainly by cutting the refined carbohydrates and sugar that spike it, and by giving your body long stretches with no food at all.
