Well, maybe metabolism isn't improved from exercise, but all I know is that even when I was mostly sedentary for two weeks this year (I rode my bike a few times, but nothing serious), I still maintained my weight really well. Didn't eat like crap, but wasn't a saint either everyday.
My leg strength is another story though...
