As long as you just drink water, eat fruit, skip meals, exercise more, and buy some laxatives outside, you will lose weight in a few days, but there may be side effects, such as dehydration, general fatigue and collapse, which may cause me to stop talking. I advise you not to listen to this method. If you really want to lose weight, you should eat reasonably, eat less and exercise more to ensure that you can lose weight healthily.
