Estimated Energy Requirement (EER) is the average energy intake that is needed to maintain the current weight of the individual. Its value depends on:
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:
PA | Male | Female |
Sedentary | 1.0 | 1.0 |
Low active | 1.11 | 1.12 |
Active | 1.25 | 1.27 |
Very Active | 1.48 | 1.45 |
