This question may belong in the workout forum, but we talk a lot about cardio here, so this is where I'll ask it.
This may be completely dumb, so please don't flame me.
After I do my morning cardio, I take a cool/cold shower. I have to get ready for work as quickly as possible and often times I'm still sweating even after I get dressed, so I try to cool down my body in the shower. There's a guy I talk to from time to time that tells me this is bad because my higher body temp is what keeps the fat burning going. If I cool off quickly, I'll stop lipolysis.
I've never heard this before, but my argument was twofold:
1) Any weight loss caused by a high body temp is water loss, due to sweat.
2) The higher body temp is a byproduct of my metabolism, it is not the CAUSE.
Somebody tell me I'm right and he's wrong.
