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:

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

Explanation: This equation estimates the minimum calories needed for basic bodily functions while at complete rest.

3. Importance of BMR Calculation

Details: Knowing your BMR helps in creating effective weight management plans, determining daily calorie needs, and understanding your body's energy requirements for maintaining, losing, or gaining weight.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, and age in years. All values must be valid (weight > 0, height > 0, age between 1-120). For accurate results, measure weight and height precisely.

5. Frequently Asked Questions (FAQ)

Q1: Why is there a different equation for women?
A: Women typically have a lower BMR than men due to differences in body composition, muscle mass, and hormonal factors.

Q2: What factors affect BMR?
A: Age, gender, weight, height, body composition, genetics, and hormonal status all influence BMR.

Q3: How often should I recalculate my BMR?
A: Recalculate whenever your weight changes significantly (5+ kg) or annually as you age.

Q4: Is BMR the same as daily calorie needs?
A: No, BMR represents basal metabolic rate. Total daily energy expenditure includes BMR plus calories burned through activity and digestion.

Q5: Can I use this calculator if I'm pregnant?
A: This calculator is designed for non-pregnant women. Pregnancy significantly alters metabolic rate and requires specialized calculations.
