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 Mifflin-St Jeor equation:

Where:

• \( weight \) — Body weight in kilograms
• \( height \) — Height in centimeters
• \( age \) — Age in years
• \( gender \) — +5 for male, -161 for female

Explanation: This equation accounts for the fact that men typically have more muscle mass than women, and that metabolism slows with age.

3. Importance of RMR Calculation

Details: Knowing your RMR helps in weight management, as it provides a baseline for determining your daily caloric needs. It's essential for creating personalized diet plans and understanding your body's energy requirements.

4. Using the Calculator

Tips: For accurate results, measure your weight and height precisely. Use morning measurements before eating or drinking. The calculator is for adults only (18+ years).

5. Frequently Asked Questions (FAQ)

Q1: How does RMR differ from BMR?
A: Basal Metabolic Rate (BMR) is measured under stricter conditions (complete rest, fasting, and thermoneutral environment), while RMR is measured under less restrictive conditions.

Q2: What factors affect RMR?
A: Muscle mass, age, genetics, hormonal status, body size, and environmental temperature all influence RMR.

Q3: How often should I recalculate my RMR?
A: Recalculate after significant weight changes (5+ kg) or every 6 months as metabolism changes with age.

Q4: Can I increase my RMR?
A: Yes, through strength training to build muscle, proper nutrition, and adequate sleep.

Q5: How accurate is this calculator?
A: It provides a good estimate (±10%) for most people, but individual variations exist. For precise measurement, consider indirect calorimetry.
