BTW, fat isn't necessarily bad either. For example, it's a hell of a lot more efficient to be fat in the extreme cold, because of the insulation that it provides than be skinny, which is why certain animals have evolved fatty-type bodies. Eskimoes possess fatty bodies. Fat also benefits swimmers as well, because of the natural buoyancy effect. Excess body fat to a degree, for example, has been correlated in some studies to be protective for elderly people.
