If your old lifestyle is the reason that makes you fat, then no matter how you lose weight, you will rebound. As a successful weight-loss person, it is strongly recommended that you don't try the same way of losing weight as violent demolitions. Using diet pills, not to mention side effects, may cause irreversible permanent damage to the body, with a high probability of rebound. I hope you can lose weight healthily, keep your mouth shut, and do aerobic exercise for more than half an hour every day. Otherwise, the intensity will be great. You can even stick to the strength that you can change from weak to strong step by step until you accept it. The key is to have enough time every time. Stick to it and form a habit. The circulation in the body has become faster, and you have not only lost weight. Why can't you come back fat?
