Let me tell you an effective method. I have practiced it myself. If your weight is above 108 kg, this method will definitely work. Just eat 3-4 apples a day, and you can't eat anything else. Take a laxative every two days (other laxatives are also acceptable, and the effect is preferably direct). If you are really hungry, eat a banana or three or four soda cookies, and you can't eat anything else. Basically, you can lose at least ten pounds from one week to ten days. I lost weight in a week 15 kg. This method is certainly harmful to the health, but it is worthwhile for the ultimate goal. As for the rebound after that, I also have a good idea. If you want to communicate in the future, let's talk about it. I wish you success in losing weight first.
