THE LEBOWSKYS
After buying her wedding gown, "I put on 80 lbs.," says Kimberly. "I couldn't get the dress over my arms." But once she and her then-fiancé, Bruce, went on The Biggest Loser, their wedding started shaping up. "We ran a 10K—I never thought I'd enjoy that," says Bruce of the prenuptial workouts. Ultimately, the two got more than just a slimmed-down ceremony out of Loser. "It bonded us more than ever," says Kimberly. "One of us might say, "Maybe you shouldn't eat that.' We're an amazing team."

THE KEELERS
"Our problem was we really loved to eat out," says Nick. He and Lael may have lost their Loser competition to the Lebowskys, but they won a fresh outlook on food. "We still love to wine and dine, but now we're a lot smarter about it," he says. "We'll order two appetizers and split an entree and dessert."
