The Reality of The Biggest Loser is stirring up old debates about the hit weight-loss show that ruled the 2000s.

Netflix viewers have reacted in disbelief over 'outrageous' documentary Fit for TV: The Reality of The Biggest Loser, which lifts the veil on the TV series.

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.

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.

Netflix's new documentary series, Fit for TV: The Reality of The Biggest Loser, streaming from today (August 15), offers a behind-the-scenes look at the popular reality TV competition that aired for 18 seasons from 2004 to 2016, with a failed comeback attempt in 2020.
