That's useless. This and losing weight are two concepts. That's a quick weight loss. It can only last for a few days in a short time. I used to be a wrestler. I lost weight to prepare for the competition. I really weighed myself in the last ten days, that is, I returned to about 80% of my original weight after eating one or two meals, and then I returned to my original weight in two or three days. This method is extremely painful and very harmful to my health. Moreover, during the period of losing weight, physical fitness will drop a lot, and even speaking will feel powerless. It's not as simple as you think, and it doesn't mean you can stick to it. So it is not feasible to lose weight in this way. Most importantly, this method needs to control your diet cruelly. Therefore, if you can eat a bowl in the original meal, the athletes' total meal for two or even three days during the weight loss period is only one bowl, which is similar to the total meal, so it is not feasible to lose weight in this way.
