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 BMR equation:

Where:

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

Explanation: This equation calculates the estimated number of calories your body burns at complete rest.

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 effective diet plans.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, and age in years. All values must be valid (weight > 0, height > 0, age between 1-120).

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this BMR calculation?
A: This provides a good estimate, but actual BMR can vary based on muscle mass, body composition, and other factors.

Q2: Should I eat below my BMR to lose weight?
A: Generally no - eating below BMR can slow metabolism. Instead, calculate your TDEE (Total Daily Energy Expenditure) and create a modest deficit.

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

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

Q5: What's the difference between BMR and TDEE?
A: BMR is calories burned at complete rest. TDEE includes all daily activities and is typically 1.2-2.5 times higher than BMR.
