The Biggest Loser - Season 5 Episode 16 "Biggest Loser" Revealed in Season Finale
5.50 90 minutes In this must-see, exciting live finale, all of The Biggest Loser contestants from this season return for a special reunion and a chance to weigh in one last time and show America how much weight they've all lost since beginning their weight-loss journeys. There are four contestants left, but America has voted on the two that fell below the yellow line in last week's episode to choose who will be the third finalist in the game. After America's vote is revealed and the third finalist is announced, the eliminated player will then weigh in with the other 16 eliminated contestants to compete for the $100,000 "at home" prize. Then it's the moment viewers have been waiting for, when one of the three finalists will be named this season's "Biggest Loser" and win the coveted grand prize of $250,000.
