Rachel Frederickson, the 24-year-old winner of NBC's reality weight-loss TV show 'The Biggest Loser,' revealed on last night's season finale that she lost a whopping 155 pounds from her original weight of 260, losing 59.62% of her body fat. 

When Frederickson revealed herself, she earned a huge amount of applause - but after coming into sharper view, it was clear that she was dramatically thinner since the last physical challenge on the television show before the finale. 

After she emerged, the cameras zoom in on show trainers Jillian Michaels and Bob Harper as they can't help but show a look of shock at her new appearance- see the screen-grab below that is quickly circulating social media.

Show fans didn't hesitate to take to twitter to share their feedback. Did you watch the season finale? Do you think that Rachel went too far to win the $250,000 prize?
