Explanation:

The Estimated Energy Requirement (EER) is the average dietary energy intake that a person needs to maintain energy balance. EER is expressed in calories and it should be calculated in each person since it depends on the specific height, weight, age, gender, and physical activity pattern. Different equations are available to calculate the EER, however it is recommended to see a nutritionist to have the more accurate calculation as well as a diet plan to allow to be as healthy as possible.
