Nothing won't rebound unless you can control your appetite and exercise more ... If you can do what you say, there won't be so many obese people in the world ... If you want to lose weight, you still have to rely on yourself. It's no use relying on those so-called drugs, it will hurt your money and your health. If you lose weight, it will be miserable at that time, so ... you still have to rely on yourself. If you are lazy to exercise, you should pay attention to your diet. Don't overeat. Don't eat easily.
