Although the air permeability of plastic wrap is poor, wrapping it around the body during exercise will really raise the local body temperature, and the body will sweat a lot in order to dissipate heat. You may lose weight after sweating, but that's because your body has lost a lot of water. As long as you replenish water, your weight will come back easily.

Extended data:

There are many enzymes involved in the process of fat "burning", and the optimum temperature of enzyme reaction in human body is between 35℃ and 40℃. Once it exceeds 40℃, the activity of the enzyme will drop sharply and even decompose. Therefore, the local high temperature caused by wrapping the skin with plastic wrap may not necessarily promote fat consumption, but may also have the opposite effect.

Some plastic wrap itself is of poor quality. When people are exercising, the waist will generate heat. As the temperature rises, there will be toxins in the plastic wrap, which are likely to enter the human body.

Plastic wrap itself is a chemical substance, which will be allergic to individual human bodies. When people are exercising, if they are wrapped with a layer of plastic wrap, the plastic will dissolve chemical components when heated due to the heat generated by exercise, so that the plastic wrap will increase the chance of skin allergy when it contacts the skin.

In fact, the most important thing to lose weight is to consume more energy than you do. So continuous exercise is more important.
