The Dietary Reference Intakes (DRIs) are a set of reference values that encompass a safe range of intake and provide recommended nutrient intakes for the United States and Canada. The DRIs for energy are used widely to provide guidance for maintaining energy balance on both an individual and group level. U.S. and Canadian governments asked the National Academies to convene an expert committee to examine available evidence and provide updated Estimated Energy Requirements (EERs) for their populations. The resulting report presents EER equations that provide a baseline for dietary planners and assessors who are estimating energy needs and monitoring energy balance to enhance the general health of individuals and populations.
