If we lose weight by dieting, the chance of rebound is great, because in the process of dieting, although we lose weight, we lose all the water in our body and don't really consume excess fat. And with the increase of dieting times, the absorption rate of food in our body is getting higher and higher. In the later stage, you may find that your weight has reached a bottleneck and you can't go down any more. Eat very little, but gain weight bit by bit. Moreover, our stomachs are fragile. We lose weight by dieting. The gastrointestinal tract will stretch and contract, and repeated stimulation will do great harm to the gastrointestinal tract. You may find that your body function is deteriorating, and even anorexia occurs in the later stage.
Judging from the law of conservation of energy, the rebound of weight loss is largely due to the fact that you lost too much weight before, but you couldn't hold on to it later, and the amount of exercise decreased, so you couldn't control it after exercise, so you really wanted to give yourself a sumptuous dinner. In this way, even if you insist on aerobic exercise for 60 minutes, you can't consume your dinner, and fat will naturally accumulate.
In short, fat people can't eat in one bite, and losing weight can't be completed in ten days and a half. Especially in the bottleneck period of weight loss, we must persist.
