Ali Vincent became the first woman to win “The Biggest Loser” during season 5 in 2008. Then-32-year-old Vincent lost 112 pounds on the NBC reality show, dropping from 234 to 122 pounds. The competition series, which aired from 2004 to 2016, awarded a $250,000 prize to the contestant who lost the most weight over the course of the season.

Rachel Frederickson faced backlash from Biggest Loser fans for her extreme weight loss. But blame should be placed on the system that exploited her.

The Biggest Loser at-home prize was awarded to an eliminated contestant who lost the highest percentage of their body weight after leaving the competition. The at-home prize was $100,000 and part of the series since the beginning. In the first season, David Fioravanti was crowned the At-Home winner.

Frederickson did end up gaining back 20 pounds within a couple months of the finale. She told Us Weekly in April 2014 that she felt 125 pounds was her “perfect weight.” She also insisted that she’d lost weight “so naturally” on “The Biggest Loser.”
