The food challenges are always interesting on NBC’s “The Biggest Loser.” Contestants can indulge (or not) to obtain some sort of prize that will give them an advantage in the game. This week it was cupcakes, but the prize was the biggest potentially in the history of the show. Finding the one-pound advantage card under the cupcake would be one thing, but then they could hold it over and let the card appreciate in value, giving that person two pounds next week, three pounds the following week, and up to eight pounds. Wow. But as some of the contestants pointed out, doing so would also put a target on that person’s back. Very true. So most of them didn’t even attempt it, but Adam and Rick did as well as Elizabeth, and Adam won, but not after ingesting about 1300 calories worth of cakes.
