1. What is Basal Metabolic Rate?

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
• \( Height \) — Height in centimeters
• \( Age \) — Age in years

Explanation: The equation estimates the calories burned at complete rest based on your body size and age.

3. Importance of BMR Calculation

Details: Knowing your BMR helps determine your daily caloric needs for weight maintenance, loss, or gain. It's the foundation for creating personalized nutrition plans.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Is this equation different for men?
A: Yes, the male equation is: BMR = 66 + (13.7 × weight) + (5 × height) - (6.8 × age)

Q2: How accurate is this calculation?
A: It provides a good estimate (±10%) for most people, but individual variations exist based on muscle mass, genetics, and other factors.

Q3: Does BMR change over time?
A: Yes, BMR decreases with age (about 1-2% per decade after 20) and changes with weight fluctuations.

Q4: How does muscle mass affect BMR?
A: Muscle tissue burns more calories at rest than fat tissue, so those with more muscle mass typically have higher BMR.

Q5: What's the difference between BMR and TDEE?
A: TDEE (Total Daily Energy Expenditure) includes BMR plus calories burned through activity and digestion.
