Myth Buster: The more I sweat during exercise, the more fat I lose.

Time to take out the trash bag.
Sweating does not mean that you are losing fat or exercising harder. Profuse sweating can be caused by poor fitness conditioning, heredity or being overweight. Sweating is your bodies way of removing heat through evaporation. Intense exercise increases heat production.
As mammals we must maintain a near constant body temperature. Death or serious illness can occur quickly if body temperature exceeds 105°F. At this temperature your bodies proteins begin to coagulate, much like an egg in a frying pan.
Lack of air movement hampers effective evaporation because the air surrounding the body saturates with water vapor, just as it does inside a sweat suit or football uniform. Wearing plastic suits or sitting in saunas or steam baths definitely makes you sweat more and have an immediate impact on weight, but this weight is merely water weight. These pounds will more than likely return once proper fluids are replenished. So wearing a plastic suit or trash bag is dangerous and counterproductive to the proper cooling of your bodies core temperature.
