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 Harris-Benedict equation:

For women: \[ BMR = 655 + (9.6 \times Weight) + (1.8 \times Height) - (4.7 \times Age) \]
For men: \[ BMR = 66 + (13.7 \times Weight) + (5 \times Height) - (6.8 \times Age) \]

Where:

Explanation: The equation estimates your body's energy requirements at complete rest based on your size, age, and gender.

3. Importance of BMR Calculation

Details: Knowing your BMR helps in weight management by determining your daily calorie needs. It's the foundation for calculating your Total Daily Energy Expenditure (TDEE) when combined with activity level.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, and age in years. Select your gender. For accurate results, measure your weight and height precisely.

5. Frequently Asked Questions (FAQ)

Q1: How is BMR different from TDEE?
A: BMR is calories burned at rest, while TDEE includes calories burned through daily activities and exercise.

Q2: How can I use BMR for weight loss?
A: Create a calorie deficit by consuming fewer calories than your TDEE (BMR × activity factor).

Q3: Does muscle mass affect BMR?
A: Yes, muscle tissue burns more calories at rest than fat tissue, so higher muscle mass increases BMR.

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

Q5: Are there more accurate methods than equations?
A: Indirect calorimetry measures oxygen consumption for precise BMR, but equations provide good estimates.
