A reality show I would actually watch Take 10 fatties who claim they mysteriously remain fat despite starving themselves. Put them on an island or whatever for 30 days. Put 450,000 calories worth of food and drink on the Island. That's 1500 calories per day, per fattie. Set up hidden cameras and shit, recording how much they actually eat. The food will run out in the 2nd week. Audience gets to laugh as they accuse each other of stealing, hoarding, etc.  (note inspired by this comment from @interstate-15)
