A no carb diet differs from a low carb diet in one crucial element – not even a little carbohydrate is allowed. In addition to being more intense, this makes the no carb dieter dependent on alternative sources of food types for meeting energy requirements.
Fats and proteins are the common alternatives. Of these, fat oxidation causes the formation of ketone bodies. This means a no carb diet imposes a ketogenic state upon your metabolism. Such a state is not normally seen in a situation where your body uses carbs for energy. That is the reason why some nutritionists advocate getting a doctor’s opinion before embarking upon a no carb diet.
