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.”

From tension between Bob Harper and Jillian Michaels to one contestant nearly dying on the set, the new series was full of secrets.

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 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 is never one to hold back. In an Aug. 19 Instagram post, she called out fellow TV icon Jay Leno for a mean-spirited 2009 segment from "The Tonight Show with Jay Leno," which was revisited in the new Netflix docuseries " Fit for TV: The Reality of the Biggest Loser ."
