The Obesity Code: Unlocking the Secrets of Weight Loss (Why Intermittent Fasting Is the Key to Controlling Your Weight)

by Jason Fung

THREE MEALS A DAY. NO SNACKS. LET’S TURN BACK the clock to the U.S. in the 1960s. Food shortages from the war are a thing of the past. Obesity is not yet a major issue. Why not? After all, they ate Oreo cookies, KitKats, white bread and pasta. They ate sugar, although not quite as much. They also ate three meals per day, with no snacks in between. Let’s assume breakfast is taken at 8 a.m. and dinner at 6 p.m. That means that they have balanced ten hours of eating with fourteen hours of fasting. The periods of increased insulin (feeding) are balanced by periods of decreased insulin (fasting). Eating large amounts of refined carbohydrates like sugar and white bread makes for higher insulin peaks. So why was obesity slow to progress? The decisive difference is that there was a daily period of low insulin levels. Insulin resistance requires persistently high levels. The nightly fasting caused periods of very low insulin, so resistance could not develop. One of the key factors in obesity’s development was removed.
