The Biggest Loser winner Rachel Frederickson has stopped dodging questions regarding her dramatic 105-pound weight, insisting she worked out a little too hard but doesn't have an eating disorder.

"Maybe I was a little too enthusiastic in my training to get to the finale," Frederickson, who lost 155 pounds total on her slim 5'5" frame during the reality weight-loss competition's fifteenth season, told People

Frederickson's weight dropped from 260 pounds to 105 pounds and she lost just about 60 percent of her body weight to claim the show's $250,000 grand prize at last week's live finale.

The 24-year-old subsequently avoided addressing whether she thought she became "too skinny" or "took things too far," however, she has a BMI of only 17.5, which is considered underweight for her height, according to the National Institute of Health.

In response to rumors Frederickson has been suffering from an eating disorder, she said, "I am very, very healthy."

Frederickson was reportedly carefully monitored over the course of seven-and-a-half months during the show, including the days before the finale.

"Rachel passed all the required medical tests ensuring she was healthy," The Biggest Loser executive producer Dave Broome told People.

Frederickson's margin of loss was the highest percentage ever posted by any contestant in the history of The Biggest Loser. She spent most of her time on the show as a member of trainer Dolvett Quince's Red Team, who has now admitted he was "shocked" by her transformation.

"The first thing that went through my mind was, 'That's just too much,'" Quince told the magazine.

Quince initially acted happy for Frederickson but posted on his Facebook page after the finale aired that his client's "journey to good health has not yet ended" and her health continues to be his "main concern."

Fellow The Biggest Loser trainer Bob Harper also recently expressed how he was "stunned" by Frederick's current 105-pound weight.
