The Biggest Loser has been met with some fierce criticism as Rachel Frederickson has won the latest season weighing just 105lbs, with some viewers claiming that she had lost too much weight, and one said she looked "sickly".
Now her trainer, Dolvett Quince has insisted that his priority is her health. The 24-year-old started her journey on the show at 260lbs before going on to lose 60 per cent of her total body weight, clinching the $250,000 prize.

But as the confetti hailed down, the 5ft4/5ft 5 winner's victory was tainted with criticism as her new weight would actually make her underweight on the Body Mass Index scale that is used by doctors.
Veteran trainers on the show Jillian Michaels and Bob Harper, who did not work with Rachel, looked visibly shocked at her appearance.
Last night, Dolvett posted on Instagram: "Last night's Biggest Loser Finale has sparked a huge reaction and I do not want the day to end without addressing it. 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 in my main concern and her journey to good health has not yet ended!!"

Meanwhile Bob and Jillian have distanced themselves from Rachel's weight loss journey, despite working on the show, releasing a joint statement in a post on Facebook.
"Jillian and I want to take a moment to congratulate all of the BL contestants on their hard work," it read. "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.
"Any questions about the contestants on The Biggest Loser should be directed to the show's producers."
But the Los Angeles-based champion of the show spoke to reporters yesterday following her win, and said that she had been following the plan given to her by the Biggest Loser. "I think that with my journey, I truly found the person I want to be, so it's about the lifestyle for me," the Reality World reports.

"I never felt this great and I know I'm going to feel ever better, because this life is just so open to me and I can't wait to take charge, because that's what I gained back. It's confidence, it's assuredness of myself to just take charge and conquer this life."
When asked if she had taken her weight loss too far, the former national swimmer replied: "Um, I have had support systems in place the entire time I was on The Biggest Loser. We are given a calorie budget and I stuck to that. I've done lots of working out and the finale was very enthusiastic."
While social networks were ablaze with heated discussions about her weight loss and appearance, with some speculating that she may suffer from an eating disorder, Rachel was shocked when asked about the rumours: "Oh gosh, I didn't even see that [referring to the rumours].
"I feel like my journey on The Biggest Loser was my path and I followed the advice and has the support of the medical team at The Biggest Loser the entire journey."
She added: "So it's just been natural and I've enjoyed every part of it. So I'm going to continue on that path and maintain this healthy lifestyle and just really enjoy this new life."
Rachel insisted that she didn't change her diet from the ranch, but said that she exercised a "ton", consuming 1600 calories a day.
"I just continued to follow the support system that I had from The Biggest Loser my trainer [Dolvett Quince]'s plan, Doctor Cheryl's great nutritional advice, and I worked out a ton," she said. "So I just worked out, worked part-time, continued to eat super healthy, and now that I'm at maintenance, it's trying new things."
