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 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.

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

Rachel Frederickson won The Biggest Loser Season 15 in 2014 after losing a staggering 155 pounds, dropping from 260 pounds to just 105, meaning she’d shed nearly 60% of her body weight over the course of the competition. When she stepped on stage at the finale, viewers, fellow contestants, and even the show’s trainers appeared visibly stunned.

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
