'Biggest Loser' winner Rachel Frederickson 'grateful for the concern' about her weight

Critics called her dramatic loss "unhealthy" for debuting a skinny, 105-pound, 5'4" body during the finale of the NBC show.

Frederickson has since gained back 20 pounds and is speaking out about the criticism she faced over the past two months.

"I'll always be grateful for the concern everyone had," Frederickson tells Us Weekly. "I will say, I had so much positive support, even on social media. Honestly, you look at it and you say, 'Wow, if people are talking, they're concerned or they're supportive.' And at the end of the day, that's pretty amazing to have so many people aware of what I went through, what others are going through."

It wasn't always easy for her, though. "It can be challenging," Frederickson says. "But I'm really proud of the work that I did and how healthy I was. I could ignore [the controversy] because I was really proud of the work I did. And something that I really learned was that I can't be judgmental of myself or others. You never know what someone else is dealing with. I know how I lost the weight, and I know that I did it healthfully and naturally."

Frederickson is glad she went on "The Biggest Loser," for more than just losing weight. "That's what I wanted to go on 'The Biggest Loser' for, to find my confidence and my self worth. And I have found it!" Frederickson says. "I found it when I stepped on that stage, and through the backlash and the controversy, I'm helping others find theirs, too."
