"The Biggest Loser" already is off to a rousing start (thanks Tracey!), but I say you should still leave room on your TV schedule for another weight loss reality show, Lifetime's "DietTribe." It starts tonight at 9.

It's the show's second season. Last time, the premise was 5 friends -- all over 200 pounds --- who set out to lose 30 pounds before one of the friends' wedding.
