Frederickson lost a whopping 155 pounds, dropping from 260 pounds to 105, which is underweight for a woman her height (5'4"), to win the NBC reality hit series' latest season (and the $250,000 prize). Now, Biggest Loser trainer Dolvett Quince, the man behind her weight loss, is breaking his silence on her shocking weight loss.
After his fellow trainers Jillian Michaels and Bob Harper's shocked reactions during Frederickson's finale reveal spoke volumes, Quince took to his Facebook page on Wednesday night to address the controversy surrounding his contestant's transformation.
"Last night's Biggest Loser Finale has sparked a huge reaction and I do not want the day to end without addressing it," Quince wrote. "Biggest Loser is a journey which has its ups and downs. Please try not to look at one slice of Rachel's journey and come to broad conclusions. Rachel's health is and always has been my main concern and her journey to good health has not yet ended!!"
Frederickson chatted with E! News at the finale, insisting she feels "amazing."
"I feel truly alive and just transformed," she gushed. "I couldn't be more happy, more thankful to get this second chance to take charge of my life again."
On Wednesday, Frederickson thanked her supporters through a message posted on her Twitter. "I want to thank everyone for the amazing support," the winner wrote. "It's been an incredible journey and I can't wait to start the next chapter of my life."
And after their shocked reactions to Frederickson's weight loss garnered fans' attention, Michaels and Harper both weighed in (no pun intended) on the controversy.
Michaels' rep told E! News, "Jillian Michaels will not comment on Rachel's journey as she was not her trainer. She is celebrating the at-home win of her contestant, Tumi. Any questions about any of the other contestants on the Biggest Loser should be directed to the show's producers." Harper, meanwhile, wrote on his Twitter account, "Jillian and I want to take a moment to congratulate all of the BL contestants on their hard work. We're not comfortable commenting on Rachel's journey because we weren't her trainers and weren't given an opportunity to work with her at any point."
