1. What is BMR and PAL?

BMR (Basal Metabolic Rate) is the number of calories your body needs to perform basic life-sustaining functions. PAL (Physical Activity Level) is a factor that represents your daily activity level, used to calculate TDEE (Total Daily Energy Expenditure).

2. How Does the Calculator Work?

The calculator uses the NHS BMR and PAL formulas:

\[ BMR = 655.1 + 9.563 \times weight + 1.850 \times height - 4.676 \times age \] \[ TDEE = BMR \times PAL \]

Where:

\( weight \) — Body weight in kilograms (kg)
\( height \) — Height in centimeters (cm)
\( age \) — Age in years
\( PAL \) — Physical Activity Level (1.2-1.9)

Explanation: The BMR formula estimates your resting metabolic rate, while TDEE calculates your total daily calorie needs based on your activity level.

3. Importance of BMR and TDEE Calculation

Details: Understanding your BMR and TDEE is essential for weight management, creating appropriate diet plans, and setting realistic fitness goals. It helps determine your daily calorie needs for maintenance, weight loss, or weight gain.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, and select your appropriate PAL level based on your daily activity. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between BMR and TDEE?
A: BMR represents calories burned at complete rest, while TDEE includes all daily activities and represents total calories burned in a day.

Q2: How accurate is this calculator?
A: This provides a good estimate for most people, but individual variations in metabolism may affect accuracy. It's best used as a starting point.

Q3: Should I use BMR or TDEE for weight loss?
A: Use TDEE as it represents your total daily energy expenditure. For weight loss, consume fewer calories than your TDEE.

Q4: How often should I recalculate my BMR/TDEE?
A: Recalculate whenever your weight changes significantly (5+ kg) or your activity level changes substantially.

Q5: Are there different formulas for men and women?
A: Yes, this formula is specifically for women. The Mifflin-St Jeor equation is commonly used for both genders with different coefficients.
