1. What is the EER Equation?

The Estimated Energy Requirement (EER) equation calculates the average dietary energy intake predicted to maintain energy balance in healthy adult men. It accounts for age, physical activity level, weight, and height.

2. How Does the Calculator Work?

The calculator uses the EER equation for adult men:

Where:

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

Explanation: The equation accounts for basal metabolic rate (first two terms) and adds energy expenditure based on physical activity level.

3. Importance of EER Calculation

Details: EER is crucial for nutritional planning, weight management, and ensuring adequate energy intake for individuals based on their specific characteristics and activity levels.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What are the PA level categories?
A: Sedentary (1.0), Low Active (1.11), Active (1.25), Very Active (1.48). Choose based on your daily physical activity.

Q2: Is this equation suitable for women?
A: No, this is specifically for adult men. Women have a different equation.

Q3: What's a typical EER range?
A: For average adult men, EER typically ranges between 2000-3000 kcal/day depending on size and activity level.

Q4: How accurate is this calculation?
A: It provides a reasonable estimate for healthy adults but individual variations exist based on body composition and metabolism.

Q5: Should this be used for weight loss planning?
A: For weight loss, you'd typically consume 500-1000 kcal/day less than your EER, depending on goals.
