Personally, I think that no matter how you lose weight, as long as you stop, don't insist on exercise and don't control your diet, it will cause a rebound. After all, they are not people who eat too much and are not fat. This is like saying that after you use beauty products, if you don't take care of your skin, it will still return to its original appearance, or it may get worse because you stay up late to eat spicy food every day. Weight loss products are just tools for us to lose weight quickly, and after losing weight, we must keep it ourselves. It is irresponsible for our future life.
