Feb. 5, 2014 -- Rachel Frederickson is the reason "The Biggest Loser" was created.
The 24-year-old voiceover artist began season 15 weighing 260 pounds.
Last night, she was crowned the winner - now weighing a mere 105 pounds. That's 155 pounds she lost! Yes, she lost well more than half her original weight (60 percent, actually).
"Knowing that I can take control and do anything that I want … it's been amazing," she said on the show Tuesday night.
She also won $250,000 for shedding all the weight. Not a bad night at all.
Yes, this is her below!
