Frederickson dodged questions about the mixed reactions during press interviews Wednesday and said she was "excited" about her results. Her specially assigned trainer, Dolvett Quince, released his statement on Wednesday night.
"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 in a Facebook post. "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!!"
Fellow trainers Jillian Michaels and Bob Harper distanced themselves from the controversy on Wednesday, writing in a joint statement that they were "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."
"Any questions about the contestants on the Biggest Loser should be directed to the show's producers," they added.
Social media users cited the pair's finale facial reactions as evidence that they were just as surprised by Frederickson's weight loss as everyone else.
