Non-Obese American Nudists

This is a group for the relative minority of American nudist who have managed to maintain a nice HWP body rather then allowing it to balloon out into grotesque proportions.

So many obese female nudists

In American there is a severe weight problem, yet it seems even more pronounced among women at nudist resorts. Does anyone have an idea as to why there appear to be so many obese females at American nudist camps?
