Huh, I might have to look into that. I've always had a "high metabolism" in that I can eat enormous quantities of food (and calories) and still struggle to put on weight. If I don't lift weights often I lose weight until people comment on how skinny I am. I get the shakes and feel horrible if I skip a single meal, or if I don't constantly consume food - doubly so when working out. I also use the bathroom often, certainly every day.
