'Biggest Loser' Winner Dubbed Too Thin

It might be the last phrase a contestant on The Biggest Loser expects to hear–you’re too skinny.

Yet the winner of this season’s Biggest Loser competition is getting called just that after Tuesday’s live finale on the NBC reality show.

The image of a newly slim Rachel Frederickson shocked even the show’s fitness coaches, Jillian Michaels and Bob Harper, whose stunned looks at the sight of the contestant caused Twitter to buzz with concern.

Frederickson’s dramatic weight loss and new skinny figure caused plenty of debate on social media. While some came to her defense saying she had to lose a lot of weight to win and that she would probably put some back on after the show, it appeared more were concerned that she had gone too far with her weight loss questioning the ethics of the show and its message to impressionable viewers.

Frederickson narrowly beat her fellow weight loss contestants for the $250,000 grand prize.
