The study will examine if a standard group-delivered cognitive behavioral lifestyle intervention for weight loss can be improved via the incorporation of a novel body image intervention designed to address body image and improve weight loss outcomes in a sample of women with overweight/obesity.
Weight loss is associated with improved morbidity and mortality in people with overweight/obesity. Lifestyle-focused interventions reliably produce modest weight loss. While some comprehensive multidisciplinary weight management interventions include behavioral and psychosocial aspects of behavior change, including brief body image education, few have focused substantially on body image as a potentially salient influence on motivation and/or successful outcomes. Body image is an individual's perception of their physical self. A common psychosocial correlate of obesity is body dissatisfaction, and research has shown that individuals with obesity are more often dissatisfied with their bodies than individuals without obesity. Multiple studies suggest that improving body image might enhance eating self-regulation during weight management interventions and engagement in physical activity. Additionally, negative body image has been associated with detrimental health outcomes, such as emotional eating and avoidance of physical activity. Although body image has been addressed in the context of obesity and weight management, it is often done in a cursory manner. To date, no weight loss programs have attempted to develop a novel body image intervention that specifically targets the necessary dichotomy between body acceptance and expectable desire for body changes in a weight loss program. As such, the investigators will examine if a standard group-delivered cognitive behavioral lifestyle intervention for weight loss can be improved via the incorporation of a novel body image intervention designed to address body image and improve weight loss outcomes.

A body image protocol designed to improve outcomes in a group-delivered multidisciplinary weight loss program by addressing body acceptance within a context of positive behavior change and utilizing existing body discomfort and re-purposing it as an agent of motivation.
