1. What is Resting Metabolic Rate?

Resting Metabolic Rate (RMR) represents the number of calories your body burns at complete rest to maintain basic physiological functions like breathing, circulation, and cell production. It accounts for 60-75% of your total daily energy expenditure.

2. How Does the Calculator Work?

The calculator uses the Harris-Benedict equation:

Where:

• \( RMR \) — Resting metabolic rate (kcal/day)
• \( W \) — Weight in kilograms (kg)
• \( H \) — Height in centimeters (cm)
• \( A \) — Age in years
• \( s \) — Sex coefficient (+5 for male, -161 for female)

Explanation: This equation estimates your basal energy requirements based on your body size, age, and gender, providing a foundation for determining daily caloric needs.

3. Importance of RMR Calculation

Details: Knowing your RMR is essential for weight management, creating effective diet plans, setting appropriate calorie targets for weight loss or gain, and understanding your body's energy requirements.

4. Using the Calculator

Tips: Enter weight in kilograms, height in centimeters, age in years, and select your gender. For accurate results, use precise measurements and fasted morning values when possible.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between RMR and BMR?
A: BMR (Basal Metabolic Rate) is measured under strict laboratory conditions, while RMR is measured under less restrictive conditions and is typically about 10% higher than BMR.

Q2: How accurate is the Harris-Benedict equation?
A: It's generally accurate within 10% for most people, though individual variations in muscle mass, body composition, and metabolic health can affect accuracy.

Q3: What factors can affect my RMR?
A: Muscle mass, age, gender, genetics, hormone levels, body temperature, and environmental factors can all influence your metabolic rate.

Q4: How often should I recalculate my RMR?
A: Recalculate every 3-6 months or after significant weight changes (±5 kg) to ensure your calorie targets remain appropriate.

Q5: Can I increase my RMR?
A: Yes, through strength training to build muscle, adequate protein intake, proper hydration, and maintaining an active lifestyle.
