Weight is not the key, but the ratio of body protein to fat. If you have more fat, your body will be bloated; Eat more protein and less fat, and you can keep slim. Because protein is about three times heavier than fat, people who are heavy may not be obese, but the waist is too thick, and there must be too much fat accumulation. Therefore, the key is to see whether the figure is getting better, not puffiness. As long as the muscle content is moderately increased (that is, the protein ratio is increased), the figure will become slimmer and slimmer, which is more beneficial to health.
