"Maybe I was a little too enthusiastic in my training to get to the finale," says the 24-year old of her six-hours-per-day workout routine and 1,600-calorie-per-day diet, though she insists:

"I am very, very healthy."

Producers add that they closely monitored Frederickson throughout her seven-and-a-half months on the series, including in the days before the finale.

"Rachel passed all the required medical tests ensuring she was healthy, the show's executive producer, Dave Broome, tells the magazine.

On a conference call with reporters shortly after her victory, Frederickson said only takes positives away from the experience.

"I've officially found that proud, confident girl that I lost. I was an athletic national-level swimmer, and to have that athlete come back again, it's just truly an amazing feeling and I'm going to embrace the new me and continue this journey," she said. "And my body is going to balance and find its way with the new maintenance and it will be perfect."
