简要总结
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.

研究组 & 干预措施
Behavioral Weight Loss + Healthy Thinking
Participants will receive a 4-week behavioral weight loss intervention based on evidence-based weight loss strategies focused on diet, exercise, and behavioral skills. In this treatment, participants will be asked to read short passages related to nutrition and a healthy lifestyle through our study website twice a day for the duration of treatment.
干预措施: Behavioral Weight Loss + Healthy Thinking (Behavioral)
Behavioral Weight Loss + Future Thinking
Participants will receive a 4-week behavioral weight loss intervention based on evidence-based weight loss strategies focused on diet, exercise, and behavioral skills. In this treatment, participants will create descriptions of upcoming positive events and will be asked to read short passages through our study website at least twice a day for the duration of treatment.
