1. What is Resting Metabolic Rate?

Resting Metabolic Rate (RMR) is the number of calories your body burns at rest to maintain basic physiological functions such as breathing, circulation, and cell production. It represents the minimum energy required to keep your body functioning while at complete rest.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ RMR = (9.99 \times Weight + 6.25 \times Height - 4.92 \times Age + s) \times Activity Factor \]

Where:

Explanation: The formula calculates basal metabolic rate adjusted for physical activity level to estimate total daily energy expenditure.

3. Importance of RMR Calculation

Details: Knowing your RMR is essential for weight management, creating effective diet plans, setting appropriate calorie intake goals, and understanding your body's energy needs for optimal health and fitness.

4. Using the Calculator

Tips: Enter accurate weight in kg, height in cm, age in years, select gender, and choose the appropriate activity factor that matches your daily physical activity level.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between RMR and BMR?
A: RMR (Resting Metabolic Rate) and BMR (Basal Metabolic Rate) are often used interchangeably, but BMR is measured under more strict conditions while RMR is slightly higher and more practical for daily use.

Q2: How accurate is this calculation?
A: This formula provides a good estimate for most people, but individual variations exist. For precise measurements, professional metabolic testing is recommended.

Q3: How often should I recalculate my RMR?
A: Recalculate whenever your weight changes significantly (5+ kg), or every 3-6 months to account for natural metabolic changes.

Q4: Can RMR change over time?
A: Yes, RMR can decrease with age, weight loss, or decreased muscle mass, and increase with muscle gain or certain medical conditions.

Q5: How can I increase my RMR?
A: Building muscle through strength training, staying hydrated, getting enough sleep, and eating adequate protein can help increase your metabolic rate.
