1. What is BMR?

BMR (Basal Metabolic Rate) is the number of calories your body needs to perform basic life-sustaining functions while at complete rest. It represents the minimum energy required to maintain vital functions such as breathing, circulation, and cell production.

2. How Does the Calculator Work?

The calculator uses the BMR equation:

Where:

• \( weight \) — Body weight in kilograms (kg)
• \( height \) — Height in centimeters (cm)
• \( age \) — Age in years

Explanation: This equation calculates the basal metabolic rate based on your body's basic energy requirements at rest.

3. Importance of BMR Calculation

Details: Knowing your BMR is essential for weight management, creating effective diet plans, and understanding your body's energy needs. It helps determine your total daily energy expenditure when combined with activity level.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What factors affect BMR?
A: BMR is influenced by age, gender, weight, height, body composition, and genetic factors.

Q2: How often should I calculate my BMR?
A: Recalculate your BMR every 3-6 months or when there are significant changes in your weight or body composition.

Q3: Is BMR the same as calories burned?
A: No, BMR is only the calories burned at complete rest. Total daily energy expenditure includes BMR plus calories burned through activity.

Q4: Can I increase my BMR?
A: Yes, through building muscle mass, regular exercise, proper nutrition, and adequate sleep.

Q5: How accurate is this BMR calculation?
A: This provides a good estimate, but individual variations exist. For precise measurements, professional metabolic testing is recommended.
