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 RMR equation:

Where:

• \( Weight \) — Body weight in kilograms (kg)
• \( Height \) — Height in centimeters (cm)
• \( Age \) — Age in years
• \( s \) — Gender factor (5 for men, -161 for women)

Explanation: This equation estimates the minimum calories needed to sustain vital body functions while at complete rest, taking into account individual body composition and demographic factors.

3. Importance of RMR Calculation

Details: Knowing your RMR is essential for creating effective weight management plans, determining daily caloric needs, and optimizing nutrition strategies for health and fitness goals.

4. Using the Calculator

Tips: Enter weight in kilograms, height in centimeters, age in years, and select gender. All values must be valid (weight > 0, height > 0, age between 1-120).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between RMR and BMR?
A: BMR (Basal Metabolic Rate) is measured under stricter conditions (complete rest, fasting, thermoneutral environment), while RMR is measured under less restrictive conditions and is typically slightly higher.

Q2: How accurate is this RMR calculation?
A: This provides a good estimate for most healthy adults, but individual variations in muscle mass, body composition, and metabolic health can affect accuracy.

Q3: What factors influence RMR?
A: Key factors include age, gender, body size and composition, genetics, thyroid function, and environmental temperature.

Q4: How often does RMR change?
A: RMR decreases with age (about 1-2% per decade after age 20) and changes with weight fluctuations, muscle mass changes, and hormonal variations.

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