Overview
Brief Summary
This study aims to test two strategies for weight loss. Participants will be randomly assigned to one of the two 4-week weight loss programs: (1) a behavioral weight loss program that involves recording weekly weight, physical activity, and caloric intake plus daily exercises in which information about a healthy lifestyle is reviewed or (2) a behavioral weight loss program that involves recording weekly weight, physical activity, and caloric intake plus daily exercises in which descriptions of positive future events are reviewed. Throughout the study, participants will complete assessments that examine the effects of the interventions on delay discounting, physical activity, weight, and other important health and psychosocial outcomes.
