In another experiment, volunteers ate two diets in a random order – one 10 per cent carbs and 75 per cent fat, the other 75 per cent carbs and 10 per cent fat. Contrary to what the carbohydrate–insulin hypothesis would have predicted, it was found that participants actually ate 700 fewer calories per day on the high-carb diet, and that only the high-carb dieters reported a significant loss of body fat.
