Some have pre-wedding jitters, but Season 4 "The Biggest Loser" contestant Neil Tejwani had pre-wedding surgery instead. Going from 421 pounds to 210, 26-year-old Neil Tejwani literally lost half of himself while competing on the show in 2007. Soon after he popped the question to long-time girlfriend Stefani Nigro.

Impressively, Tejwani has maintained a healthy weight of 230 pounds by working out five days a week, bypassing white bread and drinking less soda. But losing all that weight left Tejwani with a bunch of excess skin. So last spring, he sought a final tuxedo-tweak in preparation for his October 24, 2009 wedding -- six-hours of plastic surgery. Tejwani's plastic surgeon removed 15 pounds of excess skin and fatty tissue for a serious shape transformation.

The former "Loser" looked sharp in a Wilke-Rodriguez tuxedo on one of the biggest days of his life. But dropping those additional 15 pounds does not mean calorie-counting is over. "We did however make sure to bank up a few extra calories for our big day, so we don't feel too guilty indulging a bit or enjoying the open bar!" Tejwani told PEOPLE magazine. Seems Tejwani is dedicated to a forever-healthy lifestyle, and he's got the body to show for it.

Keeping the weight off after "The Biggest Loser" is no guarantee, but former contestants like Erik Chopin are not giving up the fight.
