Olivia Ward is now a living, breathing testament to the benefits of determination and putting one's mind to accomplishing a goal, no matter how substantive.

After an incredible 129-pound weight loss over a span of eight months, the New York City opera singer was crowned Season 11's Biggest Loser on NBC Tuesday.

Here's a before-and-after display of what she achieved:

Ward and sister Hannah Curlee became breakout stars following a sensational run during the trip to New Zealand earlier this year, both making the finals.

Also in the final four ahead of the finale were Irene Alvarado and Jay Jacobs, who vied for America's vote and the right to compete for the ultimate prize.

Joining Hannah and Olivia in an all-female final three was Irene, who became a best buddy to the Purple Team during the season. All four were worthy.

In the end, it was Olivia Ward who edged the competition and was crowned the winner. But obviously, all of these giant losers were winners last night!
