Biggest Loser diet contest

It's almost half-way through on the local edition of the biggest loser. Next Monday, I will have my weight and bodyfat checked again. The half-way point winner will be announced on Saturday and will win $500. Do I expect to win? Not exactly. After 2 months, I have lost somewhere between 8 and 12 lbs, depending on how much salt I've eaten the day before. The Biiggest Loser contest on TV shows people losing 20 and 30 lbs in ONE WEEK. I don't lose that many ounces in one week.
