News Summary: Put cash on the line to lose weight
By The Associated Press
CASHING IN: DietBet.com and HealthyWage.com offer cash rewards for meeting your goals. The GymPact app pays out money if you hit the gym when you say you will.
HOW IT WORKS: The sites and app make their money by taking a cut of the money pooled from those that don't meet their goals.
