It's useless I tell you, all the weight-loss products I have used, including it, have no effect. I really lost a lot of weight after using it, but it rebounded immediately after a while, and it was heavier than before. Most of the human body is water. In fact, it reduces moisture. The fat man's body itself is in a state of water shortage, and it is also reducing water. After a while, your water will rebound! Drugs and weight loss machines are useless. You'd better control your diet and exercise.
