While the exact format for the season finale of "The Biggest Loser" changes each season, it typically includes a reveal of the remaining contestants after leaving the Biggest Loser Ranch and a final weigh-in to announce the winner. The episode also contains a retrospective of the current season.
The NBC reality weight loss competition "The Biggest Loser" involves the journey of several contestants, sometimes as individuals and sometimes as pairs, as they work to lose weight and complete different challenges, with the ultimate goal of winning a cash prize at the end of the season. Over the course of each episode, the contestants learn about how to live a healthy lifestyle and participate in numerous workout routines led by personal trainers, such as Jillian Michaels and Bob Harper. The contestants also participate in special challenges meant to test their physical and mental abilities, with rewards ranging from cash prizes to special privileges on the show.
The end of each episode includes a final weigh in, which tracks the weight loss of each contestant over the course of the previous week. The contestant who loses the least amount of weight is eliminated from the show. This general structure continues until there are only a small number of contestants left, leaving the final weigh-in for the season finale.
