Rachel Frederickson – 155 Lbs
Rachel Frederickson is an entrepreneur used to the idea of gaining to win. But when she entered “The Biggest Loser” competition in 2014, she had to change tact, because this time losing was the key to winning. She adapted well–so well, that she eventually won the competition.

She lost an insane amount of weight, dropping from 260 pounds to 105 pounds. This made her one of the most talked-about winners of the competition, but also created concerns about her health. She was eventually advised to gain some weight due to the health risks of her massive weight loss.
