1. What is the EER Equation?

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

2. How Does the Calculator Work?

The calculator uses the EER equation for males:

Where:

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

Explanation: The equation accounts for basal metabolic rate and activity level to estimate daily calorie needs.

3. Importance of EER Calculation

Details: Knowing your EER helps in weight management, nutritional planning, and ensuring adequate energy intake for health and activity levels.

4. Using the Calculator

Tips: Enter your age in years, select your 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 factor values?
A: Sedentary = 1.0, Low Active = 1.11, Active = 1.25, Very Active = 1.48

Q2: Is this equation suitable for females?
A: No, this is the male equation. Females use a different equation with different coefficients.

Q3: How accurate is the EER calculation?
A: It provides a good estimate for most individuals but may need adjustment based on individual metabolism and body composition.

Q4: Should I use this for weight loss?
A: For weight loss, you would typically consume 300-500 kcal less than your EER, depending on goals.

Q5: How often should I recalculate my EER?
A: Recalculate whenever your weight, activity level, or age changes significantly (every 3-6 months).
