Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
* Dietary calcium supplementation as calcium carbonate or dairy calcium modulates energy balance in adolescents.
* Increased calcium in the diet of adolescents will increase fecal fat excretion and thereby decrease fat absorption.
* Calcium and dairy product supplementation will increase lipid oxidation resulting in an increase in energy expenditure.
