Keeping a proper amount of fat in the diet is good for losing weight. This is because: first, fat can inhibit the secretion of insulin and glucagon and promote the body's utilization of fat. Secondly, the reduction of carbohydrate intake is likely to lead to relatively more incomplete metabolism of fat in the body, resulting in a certain amount of ketone bodies. Ketones can suppress hunger. When ketone body is decomposed and excreted, it can also consume some extra heat. In addition, the right amount of fat can also make people feel full, so that dieters can naturally accept low-calorie meals without feeling hungry.

When the total calorie intake decreases, it is often accompanied by insufficient intake of inorganic salts and vitamins. So during the period of losing weight, we should eat more fresh fruits, vegetables and seafood. Foods rich in fiber (such as whole wheat products, oats, etc.) ) It feels full without supplying heat energy, and at the same time it can reduce the absorption of heat, so it is the best diet food.
