EER Estimated Energy Requirement Calculator

This (EER) estimated energy requirement calculator is an essential tool designed to compute your daily caloric needs based on multiple variables including age, gender, height, weight, and physical activity level to provide a more accurate estimation of energy needs.

The EER calculator utilizes equations developed by the Institute of Medicine (IOM), which are considered the gold standard in nutritional science. These equations factor in the basal metabolic rate (BMR) and energy expenditure from physical activity, making them more comprehensive than simpler calorie estimation methods.

Estimated Energy Requirement Formula

The EER formula varies based on gender and age groups. Here are the primary equations:

For Adult Men:

EER = 662 - (9.53 × age) + PA × [(15.91 × weight) + (539.6 × height)]

For Adult Women:

EER = 354 - (6.91 × age) + PA × [(9.36 × weight) + (726 × height)]

Where PA (Physical Activity Coefficient) values are:

• Sedentary: 1.0
• Low active: 1.12
• Active: 1.27
• Very active: 1.45

How to Calculate Estimated Energy Requirement?

Calculating EER involves a step-by-step process:

• Gather Personal Data: Record accurate height and weight measurements, Note age and gender, Assess physical activity level honestly
• Select Appropriate Formula: Choose the correct equation based on gender, Input measurements in correct units (kg for weight, meters for height)
• Apply PA Coefficient: Determine activity level, Use corresponding PA value

For a 35-year-old active male:

• Weight: 80 kg
• Height: 1.75 m
• PA: 1.27 (Active)

EER = 662 - (9.53 × 35) + 1.27 × [(15.91 × 80) + (539.6 × 1.75)]
    = 662 - 333.55 + 1.27 × (1272.8 + 944.3)
    ≈ 2,821 calories/day

What is the EER measurement for nutrition?

The EER measurement serves as a cornerstone in nutritional planning. It helps:

• Meal Planning: Guides portion sizes and meal frequency
• Weight Management: Assists in creating caloric deficits or surpluses
• Athletic Performance: Ensures adequate energy for training
• Medical Nutrition Therapy: Supports clinical nutrition interventions

What is the eer for a 25 year old man who is 72 inches tall and weighs 175 pounds

The eer for a 25 year old man who is 72 inches tall and weighs 175 pounds is 2,865 calories/day.

Let’s calculate:

• Height: 72 inches = 1.83 m
• Weight: 175 lbs = 79.4 kg
• Age: 25 years
• Assuming moderate activity (PA = 1.27)

EER = 662 - (9.53 × 25) + 1.27 × [(15.91 × 79.4) + (539.6 × 1.83)]
    = 662 - 238.25 + 1.27 × (1263.25 + 987.47)
    ≈ 2,865 calories/day

Is EER the Same as TDEE?

The EER and Total Daily Energy Expenditure (TDEE) are related concepts, they’re not identical:

EER: Uses IOM equations, focuses on long-term energy balance

TDEE: Often uses simpler formulas, may be more suitable for short-term goals

For the same person:

• EER might calculate: 2,865 calories
• TDEE might estimate: 2,750 calories
  The difference stems from varying calculation methods and underlying assumptions.
