Sperimentale: 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 .
