What Is EER?

Estimated Energy Requirements (EER) represent the average dietary energy intake needed to maintain energy balance in healthy individuals. EER depends on age, gender, height, weight, and physical activity level. Using the EER calculator, you can estimate how many calories a person needs each day.

EER Formula

The EER calculator uses the Institute of Medicine (IOM) equations. These formulas estimate the calories needed to maintain energy balance for men and women.

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:

W = Weight in kilograms (kg)
H = Height in centimeters (cm)
A = Age in years

Physical Activity Levels (PAL)

EER depends on activity level. The PAL coefficients are:

Sedentary: 1.0 – 1.39
Low active: 1.4 – 1.59
Moderately active: 1.6 – 1.89
Very active: 1.9 – 2.5

EER Equations for Different Age Groups

Group	EER Equation (kcal/day)
Males, 7–12 mo / Females, 7–12 mo	89 × Weight (kg) − 100 + 22
Males, 13–35 mo / Females, 13–35 mo	89 × Weight (kg) − 100 + 20
Males, 3–8 yr	[88.5 − 61.9 × Age (yr)] + [Physical Activity × 26.7 × Weight (kg)] + [903 × Height (m) + 20]
Females, 3–8 yr	[135.3 − 30.8 × Age (yr)] + [Physical Activity × 10.0 × Weight (kg)] + [934 × Height (m) + 20]
Males, 9–18 yr	[88.5 − 61.9 × Age (yr)] + [Physical Activity × 26.7 × Weight (kg)] + [903 × Height (m) + 25]
Females, 9–18 yr	[135.3 − 30.8 × Age (yr)] + [Physical Activity × 10.0 × Weight (kg)] + [934 × Height (m) + 25]
Males, >19 yr	[662 − 9.53 × Age (yr)] + [Physical Activity × 15.91 × Weight (kg)] + [539.6 × Height (m)]
Females, >19 yr	[354 − 6.91 × Age (yr)] + [Physical Activity × 9.36 × Weight (kg)] + [726 × Height (m)]
Pregnancy, 1st trimester (14–50 yr)	Non-pregnant EER + 0
Pregnancy, 2nd trimester (14–50 yr)	Non-pregnant EER + 340
Pregnancy, 3rd trimester (14–50 yr)	Non-pregnant EER + 452
Lactation, 0–6 months postpartum	Non-pregnant EER + 330
Lactation, 7–12 months postpartum	Non-pregnant EER + 400

How to Calculate EER (Manually)

The EER calculator helps evaluate diet and activity plans to meet health goals. By calculating your energy requirements, you can understand how your body uses energy and make informed adjustments.

Example: Calculate the estimated energy requirements of a 5-year-old girl who is physically low active.

Weight = 14 kg
Height = 1.524 m
Age = 5 years
Activity Level = 1.0 (low active)

Using the EER formula for girls aged 3–8 years:

EER = [135.3 − (30.8 × Age)] + [Activity Level × 10.0 × Weight] + (934 × Height) + 20

Substitute the values:

EER = 135.3 − (30.8 × 5) + (1.0 × 10 × 14) + (934 × 1.524) + 20

Calculation Result: EER ≈ 1564.72 kcal/day

Role of EER in Nutrition and Weight Control

The energy intake compared to EER affects weight:

Intakes above EER → weight gain
Intakes below EER → weight loss

Calories come from three macronutrients. A balanced daily intake should be:

45–65% of calories from carbohydrates
20–35% of calories from fats
10–35% of calories from protein

Frequently Asked Questions

What Should I Eat To Get More Energy?

Foods that help boost energy include:

Bananas
Fatty fish (salmon, mackerel)
Brown rice
Sweet potatoes
Coffee (in moderation)
Eggs
Apples
Water
Dark chocolate (in moderation)

How Is EER Determined for Pregnant Females?

During pregnancy (14–50 years old), additional energy needs are added to the non-pregnant EER:

1st trimester: Non-pregnant EER + 0 kcal
2nd trimester: Non-pregnant EER + 340 kcal
3rd trimester: Non-pregnant EER + 452 kcal

How Can I Boost My Energy Levels?

To naturally boost energy levels, you can:

Manage and reduce stress
Lighten your workload
Exercise regularly
Avoid smoking
Prioritize sufficient sleep
Eat energy-rich foods
Use caffeine strategically
Limit alcohol consumption
Stay hydrated by drinking water
