1. What is the BMR Equation?

The BMR (Basal Metabolic Rate) equation estimates the number of calories your body needs to perform basic life-sustaining functions. It's a fundamental calculation for weight management and creating effective diet plans.

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
• +5 — Additional calories for men
• -161 — Adjustment for women

Explanation: The equation calculates the minimum energy required to maintain vital functions while at complete rest.

3. Importance of BMR Calculation

Details: Knowing your BMR is essential for creating effective weight loss or weight gain plans. It helps determine your total daily energy expenditure when combined with activity level factors.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is 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 accurate is this BMR calculation?
A: This formula provides a good estimate for most people, but individual variations in metabolism may affect accuracy.

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

Q4: Can BMR be increased?
A: Yes, through muscle building, regular exercise, proper nutrition, and adequate sleep.

Q5: How do I use BMR for weight loss?
A: Create a calorie deficit by consuming fewer calories than your total daily energy expenditure (BMR × activity factor).
