FOND DU LAC, Wis. — Tim and Molly Haack are a combined 125 pounds lighter and their wallets are $1,200 fatter after winning a weight loss contest.

The contest, sponsored by radio station WTCX-FM of Fond du. Lac, encouraged pairs or partners to lose weight together and rewarded those who lost the greatest percentage of body weight in 12 weeks.

The Haacks went to the YMCA twice a day and completely changed their eating habits, Molly Haack said.

For their weight-loss ways, the Haacks won $1,200 in cash, a yearlong membership to the YMCA, a year's worth of free food from a sandwich chain and $1,000 in services at a salon.

"There are lots of contests that give away prizes and money, but we wanted a contest that would change someone's life," said Michael Brown, the station's marketing director.

Molly Haack said losing weight was as much mental work as it was physical.

"You have to decide to do it and be committed to it," she said. "And now I'm a better wife, mother and employee because I take better care of myself."
