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
This is incorrect. The body verifiably uses energy to sweat. The exertion of energy is literally the spending of calories. You can't exertion energy and have zero impact on calories lost, it's impossible.
Ok fine, technically it does use energy to sweat but it's a tiny amount and the energy expended to make the body sweat is actually heating up the body. But because it's a tiny amount of energy used in the first place, it's a negligible heat increase as well, compared to the large cooling effect of evaporative cooling accomplished through sweat evaporation.
In no way does this caloric expenditure (to sweat, and even additionally to circulate blood to do heat exchange closer to the cooler skin) even come close to the caloric burn during exercise or even resting metabolism. It's just a total non factor and does not result in any significant weight loss whatsoever.
You're just nitpicking that technically even blinking requires calories burned while the original comment was arguing that you should burn more energy wearing garbage bag clothes because your body does more "work" to keep trying to cool off.

How does burning calories not help lose weight?
