Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
1. To compare the effects of two interventions, a translation of the Look AHEAD lifestyle behavioral intervention program with usual care (UC) (brief nutrition counseling and referral to Nutrition Services, the current standard), on the primary outcome of weight loss and secondary outcomes of HbA1c, blood pressure, fasting lipid levels, and prescription medication (doses and costs) for diabetes and its related conditions.
We hypothesize that participants who receive the translation of the Look AHEAD program will lose significantly more weight and have lower glycemia, blood pressure, cholesterol, and drug doses and costs for these conditions than participants who receive UC.
2. To compare the effects of the two interventions on health behaviors, self-efficacy, diabetes-specific quality-of-life and patient satisfaction with quality of care.
We hypothesize that participants who receive the translation of the Look AHEAD program will be more satisfied with their care and will experience greater improvements in health behavior, self-efficacy, and diabetes-specific quality-of-life compared to participants who receive UC.
Secondary specific aim: To assess the cost-effectiveness of the two interventions and the potential cost savings in terms of reductions in medication doses. In the current environment, a cost effective approach to lifestyle change is imperative. The costs and benefits of the interventions in this project will be carefully analyzed.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group Lifestyle program
The group lifestyle program used in the IDOLc study is adapted from the first 6 months of the Look AHEAD program and will include 19 group sessions offered over a six month period. Each of 2 groups will contain up to 15 patients with type 2 diabetes and will last 1-1.5 hours. The program curriculum focuses on nutrition, activity, and behavioral topics and incorporates the use of meal replacements for the first 4-16 weeks to enhance weight loss success. The program fosters the development of knowledge and lifestyle skills to change diet and exercise habits through use of goal setting, problem solving, stimulus control and other behavioral techniques that have resulted in weight loss, weight maintenance and improved glycemic control.
Group Lifestyle Program
Usual Care
A research assistant will provide the usual care group participants with brief (\~15-20 minutes) counseling which reviews an educational handout emphasizing that modest weight loss (5 - 10%) via caloric restriction and gradual adoption of moderate increases in daily physical activity (equivalent to brisk walking for 30 minutes daily) is safe and effective in managing diabetes; and refer them to Nutrition Services for follow up.
Usual Care
