The Biggest Loser TV show is a competition reality series on NBC with episodes that have varied in length from sixty to 120. It features "weight-challenged" individuals who compete to try and lose more pounds than the other contestants. The one who pulls that off wins a $250,000 prize! Each week, the two contestants who lose the least weight must face a vote by the other players with one of them being sent home. Just like in other competitive shows, the one who did the worst is not always the one to be voted off. Sometimes a player who is disliked or seen as a greater threat is sent packing.
