1. What is the EER Equation?

The EER (Estimated Energy Requirement) equation calculates daily energy requirement by multiplying Basal Metabolic Rate (BMR) with an activity factor. It provides an estimate of the number of calories needed to maintain current body weight based on activity level.

2. How Does the Calculator Work?

The calculator uses the EER equation:

Where:

• \( BMR \) — Basal Metabolic Rate (kcal/day)
• \( Activity Factor \) — Multiplier based on physical activity level (dimensionless)

Explanation: The equation accounts for individual metabolic rate and activity level to estimate total daily energy expenditure.

3. Importance of EER Calculation

Details: Accurate EER estimation is crucial for weight management, nutritional planning, and determining appropriate calorie intake for maintaining, losing, or gaining weight.

4. Using the Calculator

Tips: Enter BMR in kcal/day and activity factor (typically ranges from 1.2 for sedentary to 2.5 for very active). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is BMR?
A: Basal Metabolic Rate is the number of calories your body needs to perform basic life-sustaining functions at rest.

Q2: How to determine activity factor?
A: Activity factors typically range from 1.2 (sedentary) to 2.5 (very active). Choose based on your daily physical activity level.

Q3: What are typical EER values?
A: EER varies significantly based on age, gender, weight, height, and activity level. Typical ranges are 1500-3000 kcal/day for adults.

Q4: Can EER be used for weight loss?
A: Yes, consuming fewer calories than your EER typically results in weight loss, while consuming more leads to weight gain.

Q5: How accurate is the EER calculation?
A: It provides a good estimate but individual variations in metabolism and activity patterns may affect accuracy.
