Records
The following table contains records for the American version of The Biggest Loser . Only records which were officially announced on the show are included .
The Biggest Loser is an American competition reality show that has run on NBC for 17 seasons, from 2004 to 2016. The show features obese or overweight contestants competing to win a cash prize by losing the highest percentage of weight relative to their initial weight. The Biggest Loser has been fairly popular for some of its run, ranking among the top 50 shows in the United States from 2004 to 2005 and again from 2009 to 2011. It has also attracted significant controversy, including both general critiques of its approach of rapid weight loss, and specific allegations that contestants have been malnourished, dehydrated, overexerted and, in some cases, been given weight loss pills, in order for them to lose as much weight as possible. The Biggest Loser format has been highly popular around the world, spawning over 30 international adaptations, some of which remain on the air. On May 13, 2019, it was announced that a reboot of the show will premiere in USA Network in 2020.
