The Biggest Loser: Season 1, Episode 8

1 - 8: Episode 8: Playing It Close to the Vest

Caroline Rhea ("Sabrina, The Teenage Witch") hosts this unscripted, one-hour series in which two competing teams follow comprehensive diet and exercise plans to undergo radical physical makeovers. In this episode, everyone "re-gains" the weight they lost after eight weeks of diet and exercise. This happens in the challenge in which they must run a quarter mile while wearing a vest weighted with the total amount of pounds the contestant previously lost. In addition, everyone reaches a personal best, although one contestant threatens to throw in the towel.
