These people are not autistic, its a subculture and part of the self diagnosis crap. Ive been around loads of autistics and they are mostly fat, the parents overfeed them.  Same with downsyndrome people. I was diagnosed with moderate/classic autism twice, i only ate when i wanted to and was a healthy weight until 7 years old when my mum made me overeat and now i have autoamune disorders cuz of that and have issues feeling full most of the time but im in control of my life and away from my crazy mum so i dont overeat. She claims i was anorexic which all my photos show i wasnt.  She worried about me being anorexic still, says i eat "f**k all" eventhough she goes all day without eating before binging on crap food.
