Energy balance

Ketogenic diets (KD) do not independently reduce energy intake or increase energy expenditure compared to non-ketogenic diets when energy density and behavioral factors are controlled; any observed weight loss is attributable to caloric deficit rather than ketosis itself.

If you are choosing a diet for weight loss, know that a ketogenic diet is not metabolically superior to a high-carbohydrate diet in terms of appetite control or energy expenditure. You will lose weight on either diet if you maintain a caloric deficit. Do not expect ketones to magically suppress your hunger or boost your metabolism beyond what is achieved by simply eating fewer calories.
