Experimental: INCENT weight loss program
INCENT: The INCENT intervention is an internet-delivered weight loss program with periodic financial incentives for weight loss. INCENT participants receive daily e-mail support with nutritional and physical activity suggestions to enhance weight loss. Monetary incentives are earned on a quarterly basis for weight loss and participants receive monthly checks that reflect the percent weight loss. A regularly calibrated scale with a built in digital camera captures an image of the participant during a weigh-in, and is used to objectively obtain weight data from participants at each quarterly weigh-in.
Behavioral: INCENT weight loss program
Tangible incentives seem to be effective in enhancing short term, but not long-term weight loss. The monetary rewards are based on participant quarterly weigh-ins and the monetary amount of incentive will be identical to the percentage of body weight lost. Participants who lose 1, 2, 3, 4, or 5% of their body weight will then be compensated with 1, 2, 3, 4, or 5 dollars per month. Dollar amounts for participants that lose more than 5% of initial body weight then increase by increments of 5 (e.g., 5-9% weight loss = $5; 10-14%=$10; 15-19%=$15; >20%=$20). These incentives will be based on quarterly weight and all percentage weight loss is calculated based on a participant's initial weight. commencement). Participants receive monthly checks that reflect the percent weight loss.
Experimental: Livin My Weigh
Livin My Weigh: The Livin My Weigh (LMW) intervention is an internet-delivered weight loss program without daily support or financial incentives. Participants receive quarterly newsletters with tips on weight loss, increasing physical activity, and menu suggestions, and optional quarterly educational sessions. Weight is measured in the same manner as the INCENT participants.

- Reach and representativeness of participants in the INCENT intervention [ Time Frame: 12 months ]Determine the reach (participation rate and representativeness)of the INCENT intervention.
- Weight Loss [ Time Frame: 6 and 12 months ]Determine, using a cluster (worksite) 2 group randomized design, if the INCENT intervention will produce objectively verified decreases in body weight in the short term (6 months) and enhance longer-term (12 months) weight control for overweight and obese employees when compared to control.
- Composite Measure of Intervention Costs [ Time Frame: 12 months ]Evaluate the cost and cost effectiveness of each intervention arm based on: A) cost per 5% reduction in body weight, B) cost per unit changes in productivity and absenteeism.
