Any slimming method has no good effect and will not rebound. Because if you don't rebound, it means that your medication has damaged the gastrointestinal function, and no matter how you eat it, it will not be digested and absorbed, and your body will soon collapse. Proper diet and exercise are the best ways to lose weight. The calories you consume are equal to the calories you consume in exercise, so your weight loss will not rebound, but will become healthier and healthier.
