DENVER -- National Jewish Health is offering to pay you to try its weight-management program, FitLogix, and you don't even need to lose weight to get the prepaid cards.

Beginning in early January, FitLogix participants who continue participating in the 12-month program will receive $10 prepaid cards after 6, 15, 25 and 47 weeks of participation in the program. Denver-based Springbok Services, Inc. will supply and service the debit cards.

"Our data clearly show that the longer people stay in the program, the more weight they lose. So, we decided to pay them to stay in the program," said David Tinkelman, vice president of health initiatives at National Jewish Health.

FitLogix uses customized personal coaching, Internet education and support and accountability through activity monitors and scales wirelessly connected to computers to help people lose weight. Since its inception, participants have lost an average of 7.5 pounds. Those who stay with the program the full 12 months lose an average of 12 pounds.

Right now, companies and health plans can sign up for FitLogix. Anthem and Colorado PERA are already involved. Individuals will be allowed to sign up by mid-January, but the price for individuals hasn't been set yet. For more details, visit the FitLogix Web site.
