Details and patient eligibility

About

Subjects will be enrolled in a stress-induced eating intervention with 5, 7, or 9 treatments or control. Treatment will comprise imagining a stressful event, engaging in a stress relief activity (Progressive Muscle Relaxation), and consuming a fruit once per day. There will be one lab visit at baseline in which participants undergo an acute laboratory stressor (i.e., speech and math tasks) and consume food from a buffet. There will be another lab visit at two weeks post-intervention. In the second (and final) lab visit, participants will repeat the acute laboratory stressor (i.e., speech and math tasks) and buffet, and additionally complete questionnaires about their experience in the study.
