1. What is BMR?

Basal Metabolic Rate (BMR) is the number of calories your body needs to maintain basic physiological functions at rest. It accounts for 60-75% of daily calorie expenditure in most people.

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: This equation estimates the calories needed to maintain basic bodily functions like breathing, circulation, and cell production.

3. Importance of BMR for Weight Loss

Details: Knowing your BMR helps create effective weight loss plans. To lose weight, you typically need to consume fewer calories than your BMR plus activity calories.

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: It's about 70% accurate for most people. For greater accuracy, consider professional metabolic testing.

Q2: How does BMR change with weight loss?
A: BMR typically decreases with weight loss since smaller bodies require fewer calories to function.

Q3: What's the difference between BMR and TDEE?
A: TDEE (Total Daily Energy Expenditure) includes BMR plus calories burned through activity and digestion.

Q4: How often should I recalculate my BMR?
A: Recalculate after significant weight changes (5+ kg) or every 3-6 months during weight loss.

Q5: Can exercise increase my BMR?
A: Yes, especially strength training that increases muscle mass, as muscle burns more calories at rest than fat.
