Of course it's your "fault", obviously. But why do you think so many people are so messed up then?
There will be no obesity if person maintains a low calorie intake.
And because certain groups promote fatness as a virtue, or that fatness is healthy.
Just a few comments above you claimed "The sheer scope of the obesity pandemic should make it clear that we are not the problem", and now you admit that it's your fault. Which one is it?
