1. What is the Energy Requirement Equation?

The Estimated Energy Requirement (EER) equation calculates the average dietary energy intake needed to maintain energy balance in healthy adult women based on age, physical activity level, weight, and height.

2. How Does the Calculator Work?

The calculator uses the EER equation for adult women:

Where:

• \( A \) — Age in years
• \( PA \) — Physical Activity Level
• \( W \) — Weight in kilograms
• \( H \) — Height in meters

Physical Activity Levels:

• Sedentary (PA = 1.0): Little or no exercise
• Low Active (PA = 1.12): Light exercise 1-3 days/week
• Active (PA = 1.27): Moderate exercise 3-5 days/week
• Very Active (PA = 1.45): Hard exercise 6-7 days/week

3. Importance of EER Calculation

Details: EER helps in planning appropriate dietary intake for weight maintenance, weight loss, or weight gain programs. It's essential for nutrition assessment and dietary planning.

4. Using the Calculator

Tips: Enter age (must be 18+ years), select physical activity level, enter weight in kg, and height in meters. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Can this equation be used for men?
A: No, this specific equation is for adult women only. Men require a different equation.

Q2: What are typical EER values?
A: Typical values range from 1600-3000 kcal/day depending on age, size, and activity level.

Q3: How accurate is this calculation?
A: It provides a reasonable estimate for healthy adult women but individual needs may vary by ±200 kcal/day.

Q4: Should this be used during pregnancy?
A: No, pregnancy requires additional energy intake not accounted for in this equation.

Q5: How often should EER be recalculated?
A: Recalculate whenever weight changes by ±5 kg or activity level changes significantly.
