The Biggest Loser' is the subject of the 2025 Netflix docuseries 'Fit for TV: The Reality of the Biggest Loser'

"The Biggest Loser" was the target of criticism practically from its start in 2004, but nevertheless ran for 18 seasons.

The Biggest Loser became a cultural phenomenon when it premiered in 2004 — but the show has been plagued with scandals and controversy as well. When NBC introduced the show, it followed a group of people deemed overweight who would compete in a 30-week competition.

Former Biggest Loser celebrity trainer Jillian Michaels took to social media to break her silence on the Netflix docu-series, Fit for TV: The Reality of the Biggest Loser.

Tracey Yukich collapsed during the first challenge on "The Biggest Loser" Season 8, later claiming she died before being transported from a beach to a hospital.
