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.”

Mockery, dangerous weight loss practices and long-term health impacts — “The Biggest Loser” was a TV phenomenon that shaped how Americans view weight.

Back in 2009, Danny Cahill won $250,000 after being crowned the winner of The Biggest Loser Season 8. He lost nearly 240 pounds on the show. Cahill started the show at 430 pounds and was down to 191 pounds by the end of his journey.

The two fitness trainers starred for many years on 'The Biggest Loser,' which promised $250,000 to the contestant who lost the most weight

Netflix’s three-part docuseries revisits the reality TV phenomenon as director Skye Borgman and EP Michael Gasparro reveal its most dramatic fights, jaw-dropping moments, and lasting scars.

However, a detail briefly touched upon in the new Netflix documentary is that a year after The Biggest Loser's initial run ended, Bob suffered a near fatal heart attack at the age of 52 while exercising.
