The thing is, I think he really IS on the diet, so they may actually not even do much about the diet on the show, and since he lost this weight basically over the summer, maybe that was just their way of telling us how he lost his weight and MOVE ON!! IF he is serious about this WOL, he may not want to "play games" about it on TV.
Who knows...........it'll be interesting to see how this is all played out. Because they really didn't "FOCUS" on the eating steak and eggs. etc..........they basically focused on how good he was looking etc.....
