What being a support worker for a literal autistic fatty has taught me. I work with a mid-30s male who is autistic, violent and needs a support worker around him 24/7. He has a criminal record but the courts decided that since he is so mentally ill, he doesn't go to jail. So guys like me are hired to hang out with him and keep him from attacking random people in public because he thought about professional wrestling. Most of my coworkers were SJW types who didnt take care of themselves and just wanted to "help" him by giving him everything he wants. He used to weigh 300lbs standing at about 5'6", but after some staffing changes he is down to around 190lb. What has been interesting is how much his sense of entitlement has changed. Once everyone started to realize he was going to die if nothing was done, we didn't care if he was going to throw a tantrum and try to fight us every day. So a lock was put on the fridge and his intake regulated. What's interesting is that his outbursts have become so much less violent. His appetites don't master him the same way, so it isn't life or death if he is a little bit hungry. Now that he has momentum he goes on the elliptical 5 days out of 7 by choice and says funny things to strangers like, "I used to be a porker." The connection between behavior and weight is undeniable.
