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 body composition factors.

3. Importance of BMR Calculation

Details: Knowing your BMR helps in creating effective weight management plans, whether for weight loss, maintenance, or gain. It serves as the foundation for calculating total daily energy expenditure.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this BMR calculation?
A: The Mifflin-St Jeor Equation is about 70% accurate for most people. For more precise measurement, consider indirect calorimetry.

Q2: Why is BMR different for women and men?
A: Men typically have more muscle mass and less body fat than women of the same weight, resulting in higher BMR.

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

Q4: Does pregnancy affect BMR?
A: Yes, BMR increases during pregnancy, especially in later trimesters. This calculator is for non-pregnant women.

Q5: How can I increase my BMR?
A: Building muscle through strength training can increase BMR, as muscle tissue burns more calories at rest than fat tissue.
