1. What is the Harris-Benedict Equation?

The Harris-Benedict equation is a widely used formula for estimating basal metabolic rate (BMR), which represents the number of calories your body needs at rest to maintain basic physiological functions. This version is specifically designed for women.

2. How Does the Calculator Work?

The calculator uses the Harris-Benedict equation for women:

\[ BMR = 447.593 + (9.247 \times Weight) + (3.098 \times Height) - (4.330 \times Age) \]

Where:

\( Weight \) — Body weight in kilograms (kg)
\( Height \) — Height in centimeters (cm)
\( Age \) — Age in years

Explanation: The equation estimates the minimum energy expenditure required to sustain vital functions while at complete rest.

3. Importance of BMR Calculation

Details: Knowing your BMR is essential for creating effective weight management plans, whether for weight loss, maintenance, or gain. It serves as the foundation for determining daily calorie needs based on 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). For accurate results, use precise measurements.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between BMR and TDEE?
A: BMR (Basal Metabolic Rate) represents calories burned at complete rest, while TDEE (Total Daily Energy Expenditure) includes all activities and is typically higher than BMR.

Q2: How accurate is the Harris-Benedict equation?
A: While widely used, it's an estimation that may vary by ±10% from actual metabolic rates. Individual factors like body composition and genetics can affect accuracy.

Q3: Should I use metric or imperial measurements?
A: This calculator uses metric measurements (kg for weight, cm for height). Convert imperial measurements if needed (1 lb = 0.4536 kg, 1 inch = 2.54 cm).

Q4: How often should I recalculate my BMR?
A: Recalculate after significant weight changes (±5 kg) or annually as age increases, since these factors directly affect your metabolic rate.

Q5: Can men use this calculator?
A: No, this calculator uses the equation specifically formulated for women. Men should use the male-specific Harris-Benedict equation.
