简要总结
The primary aim of this study is to compare the changes in body weight between a technology-based system, an in-person behavioral weight loss intervention, and a combination of both during a 12 month behavioral weight loss intervention in adults. Sedentary, healthy overweight and obese adults will be recruited to participate. Assessments will be conducted at 0, 6, and 12 months. This is a randomized trial in which participants will be randomized to one of three groups: standard behavioral weight loss (SBWL), standard behavioral weight loss plus technology (SBWL+TECH), and technology alone alone (TECH).

- •Currently being treated for coronary heart disease, diabetes mellitus, hypertension, or cancer.
- •Have a history of myocardial infarction or other heart-related surgeries.
- •Have a resting systolic blood pressure > 150 mmHg or diastolic blood pressure of > 100 mmHg or currently taking any medications that affect blood pressure or heart rate (e.g. beta blockers).
- •Currently enrolled in a commercial weight loss program, participating in another weight loss study, or in a weight loss study in the last 12 months.
- •Have lost > 5% of current body weight in the past 6 months.
