1. What is the EER Equation?

The EER (Estimated Energy Requirement) equation calculates daily energy requirements based on basal metabolic rate and activity level. It provides an estimate of the number of calories needed to maintain current body weight.

2. How Does the Calculator Work?

The calculator uses the EER equation:

Where:

• \( BMR \) — Basal Metabolic Rate (kcal/day)
• \( activity\_factor \) — Activity level multiplier (dimensionless)

Explanation: The equation multiplies your basal metabolic rate by an activity factor that represents your daily physical activity level.

3. Importance of EER Calculation

Details: Accurate EER estimation is crucial for maintaining energy balance, weight management, and designing appropriate nutritional plans for health and fitness goals.

4. Using the Calculator

Tips: Enter your basal metabolic rate in kcal/day and your activity factor. Both values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is Basal Metabolic Rate (BMR)?
A: BMR is the number of calories your body needs to perform basic life-sustaining functions at rest, such as breathing, circulation, and cell production.

Q2: How do I determine my activity factor?
A: Activity factors typically range from 1.2 (sedentary) to 2.5 (very active). Consult with a healthcare professional for accurate assessment.

Q3: What are typical EER values?
A: EER values vary significantly based on age, gender, weight, height, and activity level, typically ranging from 1500-3500 kcal/day for adults.

Q4: Can EER be used for weight loss?
A: Yes, creating a calorie deficit below your EER can lead to weight loss, while consuming above your EER can lead to weight gain.

Q5: How often should EER be recalculated?
A: EER should be recalculated when there are significant changes in weight, activity level, or body composition.
