Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The primary hypothesis for the E-LITE Study is that the CM intervention will reduce BMI more than the SM intervention, which in turn will reduce BMI more than usual care, over 15 months. Secondarily, we hypothesize that, compared with usual care, intervention participants will be associated with greater improvements in waist circumference, lipids, blood pressure, blood glucose, lifestyle behaviors, and psychosocial well-being. In addition, we will examine the durability of weight loss and behavioral change in the months after the initial 3-month intensive stage.

Self-Management Program
Online Self-Management.
Self-management program (SM)
Participants will attend a group orientation where the study nutritionist will provide an overview of the self-management lifestyle intervention program. Participants will receive instructions on how to use HeartHubTM, the American Heart Association's patient portal for information, tools, resources about cardiovascular risk assessment, goal setting, action planning, and self-monitoring.
During the remainder of the 15-month intervention, participants will receive reminders on a regular basis to use the patient portal to assist in their ongoing self-management.
Care Management Program
Care management lifestyle modification program with intensive intervention phase with exercise and nutrition specialist. Followed by a online self-management phase.
Care management program (CM)
In addition to participating in the activities described above, with the exception of the orientation session, participants in the Care Management Program will attend 12 weekly weight management classes during the initial 3 months. Classes will be co-led by a dietician and exercise specialist and will include a private weigh-in, a group discussion, a presentation of a lifestyle topic, 30 minutes of supervised moderate physical activity, followed by individual action-planning and goal-setting.
During the remainder of the 15-month intervention, participants will continue to monitor their body weight, caloric intake, physical activity, and other data according to their care plan. In addition, study interventionist will follow up with participants regularly, via secure messaging or by phone, to provide ongoing counseling and support.
