Drinking more or less water after exercise can't make you lose weight, which has nothing to do with losing weight. Exercise accelerates the metabolism of human cells, thus producing cell metabolites. Most of them are secreted into the body in the form of sweat. Cells are in a state of water shortage, so they should be replenished in time. If we think that drinking water will make us fat at this time and insist on not drinking water, we may have what people usually call "dehydration". Therefore, drinking water after exercise is appropriate and will not get fat.
