1. What is BMR?

Basal Metabolic Rate (BMR) is the number of calories your body needs to maintain basic physiological functions at rest. It represents the minimum energy required to keep your body functioning, including breathing, circulation, and cell production.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor equation for women:

Where:

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

Explanation: This equation estimates the calories burned at complete rest based on your body composition.

3. Importance of BMR Calculation

Details: Knowing your BMR helps determine your daily caloric needs for weight maintenance, loss, or gain. It serves as the foundation for calculating Total Daily Energy Expenditure (TDEE).

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, and age in years. For accurate results, measure your weight and height in the morning before eating.

5. Frequently Asked Questions (FAQ)

Q1: How does BMR differ for men and women?
A: Women generally have lower BMR than men of similar size due to higher body fat percentage and lower muscle mass.

Q2: What factors affect BMR?
A: Muscle mass, body size, age, genetics, hormonal status, and environmental temperature all influence BMR.

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

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

Q5: Is this formula accurate for everyone?
A: It provides a good estimate for most people, but those with very high muscle mass or certain medical conditions may need adjusted calculations.
