S9, E14: This week, contestants learn that the kitchen will be closed for a day and theyll have to eat their meals from a buffet table offering both high and low calorie choices. Whoever eats the most calories will win a coveted prize - the only vote at elimination. Then its off to a circuit beach workout with pro volleyball player Gabrielle Reece, and later, the players face off in a building block challenge testing their design and climbing skills. Also, Dr. Huizenga stops by to give updated "Know Your Number" health scores and reveals how many years the contestants have added to their lives since starting the show. And one player gets devastating news before the weigh-in, followed by an elimination that sends another contestant home. Alison Sweeney hosts the series and trainers Bob Harper and Jillian Michaels also star.
