Is this supposed to be a statement of tendency (i.e., "MOST people who are overweight are aware of their size") or is it supposed to be an absolute ("ALL people who are overweight are aware of their size.")? When I first gained weight in high school, I had no idea how overweight I was. It wasn't until I lost 30 or so pounds (by eating cafeteria food at college, which gives you an idea how bad my snacking was during high school) that I gained some inkling of just how fat I had been.
