can't get much simpler than that.

Well, maybe, yeah, no, not quite.
There's that whole "metabolism" thing.
The above forumula would suggest that you could lose weight by exercising more while not changing your diet.
I used to listen to Loveline with Dr. Drew, who was pretty darned right about most (not all) things-- one of his frequently harped-upon convictions was that exercise alone doesn't cut it-- you have to change your diet if you want to lose weight.
You wouldn't argue with Dr. Drew, would you?
