1. Conduct a randomized trial comparing the HWL intervention to the CBP intervention over 2 years in adult dependents of AD or retired military personnel. The primary outcome will be weight change from baseline to 2 years. The working hypothesis is that randomization to the HWL intervention will result in significantly greater weight loss over 2 years than randomization to the CBP intervention, and that greater weight loss in the HWL intervention will be associated with greater adherence to the goals of reducing energy intake and hunger.
