You might want to lose weight, but the noticeable benefits seem so far off in the future that you continually procrastinate. You need a reason to get more fit right now - how about money? A new study in the journal Archives of Internal Medicine reinforces this idea that if money were on the line, you might start on a healthier path. In fact, there's other evidence to suggest that money does matter. A 2008 study in the Journal of the American Medical Association found that financial incentives did get people to lose weight. You can find websites that offer rewards for healthy behaviors.
