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

David Broome, a co-creator of The Biggest Loser, says in the docuseries that he got the idea for the show after seeing a desperate “help wanted” ad for a personal trainer to “save my life” on a bulletin board outside of a gym. Once the show was underway, producers searched for similarly desperate contestants.

The Reality of ‘The Biggest Loser’ premiered on August 15, 2025, on Netflix. The three-part docuseries examines NBC’s The Biggest Loser, with all episodes released simultaneously.
