Estimated Energy Requirement (EER)

Estimated Energy Requirement (EER) is the average energy intake that is needed to maintain the current weight of the individual. Its value depends on:

• age;
• sex;
• weight;
• height;
• level of physical activity; and
• physiological state (e.g., pregnancy, lactation, illness).

The EER calculator calculates the estimated energy requirement using formulas as below:

Males:

EER = 662 – (9.53 * A) + PA * [(15.91 * W) + (539.6 * H)]

Females:

EER = 354 – (6.91 * A) + PA * [(9.36 * W) + (726 * H)]

where:

EER – estimated energy requirement;

A – age, in years;

W – weight, in kilograms;

H – height, in meters; and

PA – physical activity, with the following values:

PA – physical activity, with the following values:
