Yes, it is indeed the Hypothalamus that regulates your body's core temp and heat loss/preservation mechanisms. I agree wholeheartedly that that's what's happening when you sweat... your body is trying to cool itself down.
Now, I'd like to comment on my original post. Of course I wasn't trying to say that if as long as one is sweating, he is losing fat... I may not be the smartest guy out there, but even I know that the fat dude that sits in the Sauna for an hour (there's actually a guy at my gym that does this too) is not burning fat... he's just losing sub-q water. All I was saying is that for us--guys who lift weights and do cardio and diet--more sweating in this context does indeed reflect increased calories burned, increased BMR, and increased fat loss. I was totally joking about the "Biochemsitry Big Guns" thing... I don't know why y'all had to take it so seriously and start to try and disprove me at all costs. And the fact of the matter is, although I may indeed have been able to do some hardcore research into the matter and come up with some poignant rebuttles of my own, I just didn't think it was worth it B/C... without getting overly analytical about it, my original point "Sweating = Fat loss" is indeed true, as I'm sure you all would agree.
And the rest of the stuff about Imnotdutch/Shirley being a hemaphrodite lol... well I was just ------- around -- just like I do with my friends in real life. So, bro don't take it so seriously o.k.? Truce?
