If he's got a thyroid that almost doesn't work, that would be an excuse for hitting 500lbs.
Otherwise, $600 dollars is what people live on for one year in places like Burundi and Malawi. He's just a glutton, what he wants is hundreds of lives in food rations to basically be babysat into consuming less food.
Fuck paying for anything but having him put down like an animal, that's such selfish sloth for someone who lives in a dream-country and has the ability to be responsible for managing others, let alone function. people put on weight sometimes, a bad ankle or stressful job can be 50lbs-big deal. gorging yourself over decades while others starve means the only shots the public should have to pay for are SigSauer ones if he really can't control himself.
