Ok, I'm getting sucked into a new reality show on <gasp> Lifetime! It's called Fit to Fat to Fit.
It follows two people who are related by blood or marriage, one fat, one fit. The premise is the fit person gains as much weight as their counterpart wants to lose. Then they work to get both people to lose weight and get in shape. There are two married couples, and three or four pairs of siblings.
So they stop working out, and just eat everything. It's kinda sad to watch the really fit ones having to eat a bunch of crap that makes them feel sick. One guy has to gain 70 pounds in 4 months, which I can't even...70 pounds!
