This is an interesting theory, and a very minority one. The traditional theory is that obesity is caused by a person’s lack of will power, where if you don’t eat you won’t gain weight. This theory, the Carbohydrate-Insulin Model (CIM) of obesity, says that insulin is a hormone. When you eat carbs or sugar, insulin kicks in and tells your cells to burn carbs and not fat. You therefore crave more carbs and accumulate and not burn fat.
