The trainer of "The Biggest Loser" season 15 winner Rachel Frederickson has come to the reality star's defense following online criticism over her dramatic 155-pound weight loss.

The 5'5" 24-year-old won the $250,000 prize on Tuesday's finale of NBC's popular weight loss competition series after showing she had dropped 59.2 percent of her body weight in seven and a half months, going from 260 pounds to 105. This makes her slightly underweight according to U.S. Department of Health & Human Services standards. She should, according to the group, ideally weigh between 109 pounds and 145 pounds.

Following online criticism about her drastic weight loss, her trainer and show cast member Dolvett Quince took to his Facebook page to address the backlash.

"Last night's 'Biggest Loser' Finale has sparked a huge reaction and I do not want the day to end without addressing it," her trainer and show star Dolvett Quince wrote late on Wednesday. "'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 "Biggest Loser" trainer Jillian Michaels said on her own Facebook page that she and co-star Bob Harper did not feel "comfortable commenting on Rachel's journey" because they did not work with her directly on the series.

Rachel Frederickson: I eat 1,600 calories a day

Following her victory, Frederickson, who used to be a competitive swimmer, talked about her weight loss in a conference call.

"Oh gosh, I just see a strong, confident woman and I feel great. "I've never felt this great and it's very exciting!" she said, according to Reality TV World.

Frederickson was given a 1,600-calorie-a-day eating plan on "The Biggest Loser" and said she continued to follow it after taping the series.

"I am extremely proud of the way I lost the weight," she said. "I did everything so naturally and the athlete in me came back. To just work extremely hard and eat healthy, I'm definitely going to continue on this path with the support of everyone at The Biggest Loser and make them proud while I'm in this maintenance mode of life now and finding balance with exercise and putting in work and eating. So absolutely I'm going to continue being healthy."
