Did you make a 2014 New Year's resolution to drop a few pounds?

Maybe you'll find some inspiration in Rachel Frederickson, 24, a voice-over artist from Los Angeles. On Tuesday night, she was crowned winner of The Biggest Loser: Second Chances, Season 15 of the NBC weight loss reality competition.

Frederickson started at 260 pounds. She weighed in on Tuesday's episode at a mere 105.

But her dramatic loss has caused many to wonder (on Twitter Tuesday when her figure was revealed) if she lost too much weight, as she shed 60% of her body weight.

"I came here to gain back my life, and I did exactly that. I've found that proud, confident girl that has so much respect for herself," she told People backstage after the show.

After a season that included a trip to Utah Olympic Park to train with Olympic athletes, makeovers with fashion guru Tim Gunn and celebrity hairstylist Ken Paves and the show's first sprint triathlon, three finalists showed off a combined 1,700-pound loss.

Competing for the $250,000 grand prize with Frederickson were David Brown, 43, a project manager for a construction company, from Edmond, Okla., and Bobby Saleem, 29, from Chicago.

Ruben Studdard, who was the second person eliminated from this season, returned to perform the single Meant to Be with David Foster. He showed off a slimmer figure, too. He left the show weighing 423 pounds, but on Tuesday night, he returned to tip the scales at 343, bringing his total weight loss to 119 pounds.
