Gluttony run rampant

My husband became glutinous in his old age!!! I don't know what happened to him, he wasn't like this when he was young, but now he stuffs himself like crazy. It's like watching a junk yard dog eat and it's all day every day. He's eating enough for six men and weighs enough for three. It's very expensive feeding him. He's up to 360 pound and has broken four of our chairs so far. He can't dress himself anymore. He is taking appetite suppressants, which are dangerous methamphetamines by prescription, and they aren't helping at all. He insists he cannot stop eating when he stops being hungry, he says he wants to feel full. So he keeps stuffing it in. When I tell him he's eating too much he yells at me that it's my fault for being a good cook. So then I tell him I'm not going to the store anymore, I'm ashamed of the sheer volume of food I have been buying And I'm not going to cook for him. If he wants to overeat he can fix it himself. He is yelling and screaming tonight about how if I don't cook for him I am not earning my keep. Really I think I should have this man committed. He's lost his mind, right?
