Brief Summary

Currently, the best behavioral treatments for obesity only work for 50% of adults, and of those who initially succeed, most do not maintain their weight loss. One reason for this failure may be due to neurocognitive deficits found among individuals with obesity, particularly related to executive function, which make it difficult for these adults to adhere to treatment recommendations. The proposed study aims to develop a Novel Executive Function Treatment (NEXT), which when administered prior to the behavioral treatment, could help improve outcomes by addressing the neurocognitive deficits in adults with overweight or obesity.

Study Arms (2)

Novel Executive Function Training - NEXT

EXPERIMENTAL

Same as BWL with some additional strategies targeted at improving executive function to help adherence to BWL skills.

Behavioral: Behavioral Weight Loss - BWLBehavioral: Novel Executive Function Training - NEXT

Behavioral Weight Loss - BWL

ACTIVE COMPARATOR

All participants will be instructed on how to consume a balanced deficit diet of conventional foods; individual goals for energy intake will be based on initial body weight. Participants will be instructed in measuring portion sizes, counting calories (with a calorie counter provided or on their phone), and self-monitoring food intake. The physical activity program will focus on increasing both lifestyle activity and structured exercise programs. Behavior change recommendations include stimulus control, self-monitoring, goal setting, managing high-risk situations, meal planning, slowing eating, problem solving, social support, cognitive restructuring, lapse and relapse prevention skills, and maintaining weight loss.
