Original sentence: Some argue, on this basis, that the ketogenic low-carbohydrate diets offer a metabolic advantage, allowing the body to automatically eliminate food energy that it does not need even with a high-calorie diet, but this view is not widely accepted
Edited sentence: Some argue, on this basis, that the ketogenic low-carbohydrate diets offer a metabolic advantage, in that the body automatically eliminates food energy that it does not need even with a high-energy diet.This argument has not yet been demonstrated in clinical studies; one 2006 study failed to find such an advantage over non-ketogenic low-carb diets
