Kai Hibbard holds the record for being the female to shed the most weight on NBC’s The Biggest Loser. The 28-year-old Alaskan lost 118 pounds in the third season of the Reality TV hit. She was runner-up to Erik Chopin, who got rid of a staggering 214 pounds on the series.

Since the series aired, Kai, an aerobics instructor, has kept the weight off with the help of her friends, which include Heather Hansen and Pam Smith. Heather, Pam and Kai became pals while appearing on The Biggest Loser together. Their friendship is so special to Kai that she’s asked the gals to be bridesmaids at her wedding. Kai will wed her fiancée, Jake Zwiestra, on October 6, 2007.

Kai continues to eat wholesome foods which include whole-grain (not white) carbs and healthy fats and runs 45 minutes each morning and does strength-training each night.
