CHICAGO, Ill. (WPVI) -- If you're trying to lose weight, more evidence shows putting money where your goals are can help.
Records of 5,000 people who made online contracts, either making pledges to charities or wagers with friends, were more likely to reach their goals than those with no money at stake.
And the most successful people were those whose money went to causes they don't support if they missed their target weight.
Experts say the risk of losing money seems to work the best.
There are many online sites you can use to wager, or you can just make a friendly bet with a friend.
Of course, the support can also help you both get healthy.
