However, the influence of food insecurity on the effectiveness of behavioral weight loss interventions is unknown.Objective: To examine via post hoc analysis whether food security status modified patient responses to a high-intensity, lifestyle-based intervention for weight loss.Methods and Findings: The PROPEL (Promoting Successful Weight Loss in Primary Care in Louisiana) trial was a 2-year, cluster randomized, 2-group pragmatic trial done in 18 primary care clinics across Louisiana to ...References1.
