1. What is Basal Metabolic Rate (BMR)?

Basal Metabolic Rate (BMR) represents the number of calories your body burns at rest to maintain vital functions such as breathing, circulation, and cell production. It accounts for 60-75% of total daily calorie expenditure.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor BMR equation:

\[ BMR = 10 \times Weight + 6.25 \times Height - 5 \times Age + 5 \text{ (men)} \] \[ BMR = 10 \times Weight + 6.25 \times Height - 5 \times Age - 161 \text{ (women)} \]

Where:

\( Weight \) — Body weight in kilograms (kg)
\( Height \) — Height in centimeters (cm)
\( Age \) — Age in years
\( +5 \) — Male adjustment factor
\( -161 \) — Female adjustment factor

Explanation: This equation provides the most accurate estimate of BMR for most populations and is widely used in clinical settings.

3. Importance of BMR Calculation

Details: Knowing your BMR is essential for weight management, creating effective diet plans, understanding your metabolism, and determining daily calorie needs for maintenance, loss, or gain.

4. Using the Calculator

Tips: Enter weight in kilograms, height in centimeters, age in years, and select gender. For accurate results, use recent measurements and input values in the specified units.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between BMR and RMR?
A: BMR measures calories burned in complete rest, while RMR (Resting Metabolic Rate) measures calories burned at rest but may include light activities. BMR is typically slightly lower than RMR.

Q2: How accurate is this BMR calculation?
A: The Mifflin-St Jeor equation is about 90% accurate for most people. For precise measurement, laboratory methods like indirect calorimetry are needed.

Q3: What factors affect BMR?
A: Age, gender, weight, height, body composition, genetics, hormonal factors, and environmental temperature all influence BMR.

Q4: How can I increase my BMR?
A: Building muscle through strength training, staying hydrated, getting adequate sleep, and eating enough protein can help increase BMR.

Q5: Should I use BMR for weight loss planning?
A: Yes, BMR is the foundation for calculating Total Daily Energy Expenditure (TDEE), which helps determine appropriate calorie intake for weight loss.
