The idea of losing weight is to eliminate excess body fat. At present, there are only two effective ways to lose weight; The first is the physical exertion method. Is to do super sports until you sweat, that is, physical exercise (also called fat burning exercise); The second method is to drink more water to lose weight. Because drinking too much water will speed up excretion, it will also take away some nutrients while eliminating garbage in the body. The loss of nutrients will reduce the accumulation of fat, thus achieving the purpose of losing weight. Other methods of losing weight are not credible and easy to be faked.
