Don't know about 2/3 of the world, but certainly Americans need to be fat shamed into better health. And I say this as someone for whom maintaining a barely sensible weight has been a lifelong effort. I find it odd that we were so willing to ostracize smoking. Quite apologetically. Even to the point of insanity, some might say. But nonetheless, because smoking is empirically bad for your health. Well guess what? So is being overweight. And something like 95% if not more like 98%+ of overweight Americans are overweight due to behavioral factors.
