For people who say he's gonna lose some work, what's better lose some work or lose your life? Nobody lives to be old with that kind of fat body. Look at John Candy and Chris Farley, both died of a heart attack. He just won't get any jobs being the fat guy anymore.
Besides, he's rich as it is. Now he can go be a poster boy for fat guys who want to lose weight, if he wanted to. Once you got fame and money, you don't have to worry about getting jobs in the future. Just look at George Foreman, you'd think that after boxing he wouldn't have a job either, but look at him now.
