Metabolic Optimization Through Diet/Lifestyle Improvements For Youth

The overarching goal of this study is to evaluate plasma ceramides (Cers) as early nutrition-sensitive biomarkers of metabolic health. The investigators will implement a diet and lifestyle intervention to improve cardiometabolic risk factors and test the corresponding change in Cer levels. The intervention will incorporate: a) family-level engagement, enrolling both adolescents and one parent/adult caretaker (PAC); and b) a behavior change mobile health (m-health) app, which will offer real-time support, education and monitoring of diet and activity.
