Your body realises that it no longer needs carbohydrates to produce energy when you are in a state of ketosis. As a result, it looks to stored fats as a substitute energy source. The body needs ketones to power the procedure since it takes more effort to remove fats from their storage. You get a well-toned body as your body quickly consumes stubborn fats as it burns energy. Because they produce higher-quality energy than carbs, fats are the best energy source. Studies show that energy derived from burning fat is more exciting and long-lasting.
