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 for vital functions like 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 determine daily caloric needs for weight maintenance, loss, or gain. It's particularly useful when considering weight loss supplements or dietary plans.

4. Using the Calculator

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

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 greater precision, consider professional metabolic testing.

Q2: How does BMR relate to weight loss pills?
A: Some weight loss supplements aim to increase metabolic rate. Knowing your BMR helps assess their effectiveness.

Q3: Why is the equation different for women?
A: Women typically have higher body fat percentages and different hormonal profiles that affect metabolism.

Q4: Does muscle mass affect BMR?
A: Yes, muscle tissue burns more calories at rest than fat tissue. Those with more muscle mass will have higher BMR.

Q5: How often should I recalculate my BMR?
A: Recalculate after significant weight changes (±5kg) or every 6 months as metabolism changes with age.
