1. What is Basal Metabolic Rate (BMR)?

Basal Metabolic Rate (BMR) is the number of calories your body needs to perform basic life-sustaining functions at rest. This includes breathing, circulation, cell production, and nutrient processing.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor Equation:

\[ BMR (men) = 10 \times weight(kg) + 6.25 \times height(cm) - 5 \times age(years) + 5 \] \[ BMR (women) = 10 \times weight(kg) + 6.25 \times height(cm) - 5 \times age(years) - 161 \]

Where:

\( weight \) — Body weight in kilograms
\( height \) — Height in centimeters
\( age \) — Age in years
Different constants are applied based on gender

Explanation: This equation is considered one of the most accurate for estimating BMR in healthy individuals.

3. Importance of BMR Calculation

Details: Knowing your BMR helps determine your daily calorie needs for weight maintenance, loss, or gain. It serves as the foundation for creating personalized nutrition plans.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the BMR calculation?
A: The Mifflin-St Jeor Equation is about 90% accurate for most people, but individual variations in metabolism can affect precision.

Q2: What factors can affect my BMR?
A: Muscle mass, body composition, genetics, hormones, environmental temperature, and certain medications can influence your BMR.

Q3: How often should I recalculate my BMR?
A: Recalculate after significant weight changes (5+ kg), or every 6-12 months as you age.

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

Q5: How does BMR relate to total daily energy expenditure?
A: Your total daily calorie needs equal your BMR multiplied by an activity factor that accounts for your physical activity level.
