Where does it go?

I was just wondering, when you lose weight where does it go? Is there a collection of weight in some weight bank somewhere that collects it and then distributes it to others who either withdrew it or earned it as interest or dividends?  Are we given an account in this bank the moment we are born and then it goes back into the bank, available to others when we die?

Excuse me, I'd like to make a small deposit if I might . . .
