1. What is 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 BMR equation for women:

Where:

• \( W \) — Weight in kilograms (kg)
• \( H \) — Height in centimeters (cm)
• \( A \) — Age in years

Explanation: This equation calculates the minimum energy required to keep your body functioning at complete rest.

3. Importance of BMR Calculation

Details: Knowing your BMR helps determine your daily caloric needs for weight maintenance, loss, or gain. It's a fundamental component in creating personalized nutrition and fitness plans.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, and age in years. All values must be valid positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between BMR and TDEE?
A: BMR represents calories burned at complete rest, while TDEE (Total Daily Energy Expenditure) includes all daily activities and exercise.

Q2: How often does BMR change?
A: BMR changes with age, weight fluctuations, muscle mass changes, and hormonal factors. It typically decreases with age.

Q3: Can I increase my BMR?
A: Yes, through building muscle mass, regular exercise, proper nutrition, and adequate sleep.

Q4: Why is there a different formula for women?
A: Women generally have lower BMR than men due to typically higher body fat percentage and different hormonal profiles.

Q5: How accurate is this BMR calculation?
A: While this formula provides a good estimate, individual variations in metabolism, body composition, and health conditions can affect actual BMR.
