Eksperimentel: Lifestyle Education (LS)
The lifestyle curriculum will be taught in twice weekly after-school sessions of ~1.25 hours, one physical activity and one nutrition-related, delivered over 12-weeks during the course of a single academic semester.
The lifestyle program will utilize the "Shape Up" curriculum of SOSMentor, a community non-profit collaborator, modified to seamlessly integrate key concepts of the non-diet philosophy of "Intuitive Eating".
The curriculum fully encompasses health-promoting nutrition and physical activity practices consistent with consensus recommendations .

Eksperimentel: LS + Stress Reduction Guided Imagery
In addition to the after school lifestyle classes, participants will receive group Interactive Guided Imagery (IGI) consisting of standard stress reduction imagery practices, delivered once weekly for 12 weeks as an after school class of ~1.25 hours.
