Scientists claim that overeating is not the primary cause of obesity

The energy balance model fails to explain the biological causes of weight gain, whereas the carbohydrate-insulin model identifies excessive consumption of rapidly digestible carbohydrates as a key contributor to obesity. This perspective argues for a shift in focus from calorie restriction to dietary pattern change.
