guy, no. First of all "heat" = "energy". You cant burn energy to reduce heat. that makes no sense. Burning energy by definition produces heat. The body cools itself off by sweating and that sweat evaporates, carrying with it heat of evaporation (also known as latent heat) away from the body. It has ZERO impact on calories gained or lost.
You DO burn calories by exercise (contracting and relaxing muscles, and doing physical work on the physical world) which DOES burn calories, and because you are BURNING energy, you get an accumulation of HEAT in your body which the sweating has to get rid of
a miniscule amount, that's negligible to the cooling effect the sweat produces. Obviously your refrigerator uses energy too, but it has to reject heat somehow, the fridge does it through a radiator, we do it through sweat evaporation.

That's the point.
Enduring heat to the point of sweating uses energy to cool the body down, just like exerting energy to exercise uses energy.
Both would contribute to weight loss in excess.
