Estimated Energy Requirement (EER) is an estimate of the average amount of food energy you need daily to balance out your body's expenditure of energy in order to maintain body size and composition at a level of physical activity consistent with long term good health.

Energy intakes above the EER would be expected to result in weight gain, whereas intakes below the EER would be expected to lead to weight loss.

This calculator uses the Institute of Medicine equations to calculate EER. It covers all age groups, as well as pregnant and nursing mothers.
