Do sweat belts work?

The efficacy of abdominal sweat belts have yet to be verified by scientific studies. The manufacturers of these sweat belts claim that the band will heat fat cells, which makes it easier to lose stubborn fat; however, scientific researchers have not put the theory to the test.

According to the American Council on Exercise, increasing perspiration during exercise could lead to dehydration, and that the abdominal sweat bands cause an individual to sweat, but do not actually burn fat. Sweat bands most likely help reduce water weight, but as soon as the body is rehydrated, that weight comes back. It can be very confusing and frustrating for those expecting permanent results.
