In the short term, some aerobic training with plastic wrap can really lose weight. When running or exercising, wrapping thighs, arms or abdomen with thick sebum plastic wrap can raise local body surface temperature and increase local perspiration. Sweating a lot is the main reason for the obvious weight loss after exercise. So it is not difficult to see that water accounts for a large proportion of this method to lose weight. What people want to lose through exercise is the accumulated fat in the body, and plastic wrap can't bring this effect.

Studies have shown that water is an important medium for lipid metabolism in the body. When the body loses too much water, it will slow down fat metabolism, which is not conducive to fat consumption. In addition, long-term use of plastic wrap will cause the sweat on the skin surface to be unable to evaporate, and the metabolic waste in the sweat will remain on the skin surface, which will have adverse effects on the skin, and may also block sweat glands and cause skin diseases such as eczema.
