Tailored Lifestyle Intervention in Obese Adults Within Primary Care Practice - Choose to Lose

The primary objective of the study is to evaluate the effectiveness of tailored lifestyle intervention in primary care by comparing changes in the primary measure of weight and body mass index (BMI) and secondarily: physical activity (PA), fat calories consumed, and fruit/vegetable servings within the two arms (intervention and control) of the study. It is hypothesized that the intervention cohort will demonstrate greater reductions in body weight, body neglect, and fat calories consumed and greater increases in physical activity and fruits/vegetable servings after two years compared to the control cohort. The study also aims to evaluate and compare the cost of intervention for purpose per each unit of measure lost between the two arms of the study as a secondary objective. The cost of intervention will be evaluated as it relates to study replication.
