Feb. 6, 2014 -- The reveal of "The Biggest Loser" winner Rachel Frederickson came with some critics who thought the 155-pound weight loss might have been a bit too much.
The 5'5" Frederickson, a voice-over artist from Los Angeles, started the show at 260 pounds and now weighs just 105.
The winner told reporters she's happy with the change.
"I feel great," Frederickson, 24, told reporters over a conference call, US Weekly reports. "I've never felt this great, and it's very exciting!"
She continued, "Now I'm really at maintenance mode, so now it's gonna be about doing a yoga class this day, a spin class this day, and I think I'm going to try dance classes because I don't have a lot of rhythm."
She added that she's "never felt this great before" and she is going to embrace the new her.
Jillian Michaels, one of the trainers on the show, posted a statement on her Facebook page.
"Bob and I want to take a moment to congratulate all of the BL contestants on their hard work," she said. "We're not comfortable commenting on Rachel's journey because weren't her trainers and weren't given an opportunity to work with her at any point."
Frederickson's trainer, Dolvett Quince, addressed the issue on his Facebook page.
"Biggest Loser is a journey which has its ups and downs," he wrote. "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!!"
Today, Chris Powell, a host and trainer on another life-changing program, "Extreme Weight Loss," gave "Good Morning America" his take on Frederickson dropping almost 60 percent of her original weight.
"She did what she set out to do," he said. "To lose as much as you can in as short a time as you can ... she's playing a game. You need to keep that in mind."
For winning the show, Frederickson got $250,000.
Powell said Frederickson's goal should be to find "that balance" in life now that she's lost all the weight.
"Most of the people we work with they come from the over-eating," he added. "It's an unhealthy relationship with food, it's so easy to switch over to the opposite end of the spectrum by under-eating."
