Dieting can make you thinner, but basically all you excrete is water. Regard dieting as a way to lose weight, that is, like those actors, they will go on a diet all their lives and never touch rice and steamed bread. Take slimming as a lifelong career. If you go on a short diet, you will lose weight. If you don't go on a diet, you will rebound immediately. There is no doubt about it.
