Frederickson started the show at 260 pounds, and dropped 155 pounds for the win. At the finale, she looked gaunt at only 105 pounds, leaving some to wonder if she had gone too far.
Season 10 winner Patrick House, who started the show at 424 and now weighs 220, told People, "She did what she had to do. Rachel's transformation was like any ‘Biggest Loser’ contestant. She had to do the best that she possibly could, and at the end of the day, there's a carrot dangling that's a quarter of a million dollars up for grabs."
Ali Vincent, the winner of Season 5, agrees. She told the mag, "I think she chose to win."
The former contestant, who once weighed 234 pounds, explained, "I know what it's like. I gave it every single thing I had. I was working out from 10 in the morning to 2 in the morning. Is that healthy? No! But it's a conscious adult decision to win. I weighed 122 lbs. [at the finale]. I took a drink of water and I gained weight back."
Season 11 winner Olivia Ward is upset that the public is labeling Rachel as “anorexic.”
"Whether it's a healthy weight or not, it's not okay for people to put words on her like anorexic. That's disgusting. You're diagnosing without knowing her story," Ward said. "I feel so bad for her because it really robbed her of a special moment in her life."
She continued, "Granted it's never good to do anything unhealthy to yourself, but let's all support her and give her a couple of weeks.”
Ward, who started the show at 261 pounds, added, "I weighed 132 lbs. when I weighed in. I was up 6 to 7 lbs. in a couple of days, and that was just some basic water weight."
Ali Vincent said he hoped Frederickson will be back to her fighting weight soon. "If in a few months she's still exactly where she is right now, then it's our responsibility to get her some help."
