It doesn't work. To tell the truth, no weight loss product is really effective now. If it was so magical, it would have won the Nobel Prize. A lot of weight loss is to make you eat less or not. Including acupuncture. Think about it, even if you don't eat their products, you will lose weight. But once you eat it, it bounces back. I think exercise is more correct. But some people really have a hard time losing weight. I believe that a few days is not enough to produce such a great effect. If you insist on it for a month first, it will definitely have an effect.
