Netflix’s newest docuseries interviews cast, crew, and contestants on how a reality show about weight loss changed their lives.

Robert Huizenga spoke about his experience on 'The Biggest Loser' on the Netflix docuseries 'Fit for TV: The Reality of The Biggest Loser'

Netflix’s new documentary, “Fit for TV: The Reality of the Biggest Loser” just landed on the streamer and it pulls back the curtain on allegations made against producers and former cast members of NBC’s former series “The Biggest Loser.”

The documentary Fit for TV: The Reality of the Biggest Loser revealed that weight regain affected the majority of previous contestants. This pattern suggests that the show's extreme methods were not sustainable for long-term health. The lack of aftercare support may have contributed to these disappointing outcomes for the contestants.

The Reality of the Biggest Loser alum, Rachel Frederickson, lost a remarkable 59% of her body weight, from 260 to 105 pounds, winning the series in 2014.

Rosie O’Donnell has strong feelings about Netflix’s “Biggest Loser” docuseries. After watching “Fit for TV: The Reality of the Biggest Loser,” O’Donnell publicly called out Jay Leno for how he treated former contestant Tracey Yukich in the doc.

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, is shining a bright light on the old weight-loss show, and it’s not looking pretty.
