Celebrity fit club

There is show on TV called celebrity fit club where celebrity are forced to lose weight in the form of a contest. Now I'm thinking the US has an obesity problem and the problem is in the masses or in other words the average American. How stupid is it to get celebrities to do a show like this. I mean the reason they are fat isn't fast food its lots and lots of money. Oh and one other thing. Do celebrities really need more confidence? For crying out loud your famous already!
