It's the double whammy. Atleast someone who knows and admits they're fat doesn't constantly try to delude themselves.  Those self-deluder types, of all shapes and sizes, are some of the most spiteful and disgusting human beings. They see the world through a fucked up lense where reality is not bending to their delusions, so it's people and humans that are the problem. It's the only way to explain why guys aren't falling over for them (or whatever) - because men are disgusting pigs who are too stupid to see their beauty.
