Estimate the average dietary energy intakes to maintain healthy and normal individuals.
The EER calculator enables you to calculate how many calories an individual needs on a daily basis according to gender, age, height, weight, and physical activity.
Estimated energy requirements is the approximation of average dietary energy intake which helps to maintain energy in an individual with respect to a given age, gender, height, weight, and physical activity levels.
The estimated energy requirement calculator perform calculations by using IOM (Institute of Medicine Equations), to know the EER formula.
The use of estimated energy equation helps to maintain energy needs for different genders. So, look at the EER equation below:
For Men:
EER = 88.362 + (13.397 × W) + (4.799 × H) – (5.677 × A)
For Women:
EER = 447.593 + (9.247 × W) + (3.097 × H) – (4.331 × A)
Where:
EER calculations utilize physical activity coefficients to assess the energy expenditure with different physical activity levels. As, the bodies are constantly burning calories, even when we’re at rest. This consumption of calories varies depending on a number of some factors.
For the purposes, the PAL has been determined as follows:
So, take a look at the below table to make the EER calculations easy.

The EER calculator evaluates the diet and exercise plan to achieve health goals. By calculating your estimated energy requirements, you can gain valuable insights into how your body uses energy and make adjustments accordingly.
So, let us take a look at the example below to make your concept broader.
For Example:
Calculate the estimated energy requirements of a 5 year old girl, but keep in mind that she is physically low active than the young female.
Let’s put the values of total calorie requirements in the below eer formula:
= 135.3 – (30.8*Age) + ActivityLevel*(10.0*[Weight in kg]) + (934*[Height in meter]) + 20
= 135.3 – (30.8 * 5) + 1.0 * 10.0 * 14 + 934 * 1.524 + 20
= 1564.72
The energy intakes above the EER would be expected to weight gain – whereas intakes below the EER would be expected to result in weight loss.
Remember that food is converted for human’s body to function through the three yielding nutrients such as lipids (fats), protein, and carbohydrates. So, the percentage of these yielding nutrients that should need to consume daily as part of a healthy diet is:
These are the foods that have been proven to help promote energy intakes:
Pregnancy (1450 years old)
1st trimester EER = Nonpregnant EER + 0
2nd trimester EER = Nonpregnant EER + 340
3rd trimester EER = Nonpregnant EER + 452
