See what meat you want to lose. If you want to lose weight, you can lose weight without eating, or you are malnourished, but you can't lose fat. The scientific method of losing weight is mainly to reduce body fat, so it can't be said that losing weight is successful. Just by taking some measures, you lost weight in a short time, but the fat on your body did not decrease, only the water decreased. Such weight loss is harmful. The premise of scientific weight loss is that cells can get complete and sufficient nutrition. If energy is insufficient, cells will release fat.
