1. What is the Calories Burned Equation?

The Calories Burned Equation estimates your daily calorie expenditure by multiplying your Basal Metabolic Rate (BMR) by an activity factor that represents your typical daily activity level.

2. How Does the Calculator Work?

The calculator uses the Calories Burned Equation:

Where:

• \( BMR \) — Basal Metabolic Rate (calories your body needs at complete rest)
• \( Activity\ Factor \) — Multiplier based on your activity level (1.2-1.9)

Explanation: The equation accounts for both your body's basic energy needs and the additional calories burned through daily activities and exercise.

3. Importance of Calorie Calculation

Details: Knowing your daily calorie expenditure is crucial for weight management, whether your goal is weight loss, maintenance, or gain. It helps create appropriate diet plans.

4. Using the Calculator

Tips: Enter your BMR in kcal (use a BMR calculator if unknown) and select your activity level. All values must be valid (BMR > 0).

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation?
A: It provides a good estimate but individual variations exist based on metabolism, body composition, and exact activity levels.

Q2: What's the difference between BMR and TDEE?
A: BMR is calories burned at complete rest, while TDEE (Total Daily Energy Expenditure) includes all activities - this calculator estimates TDEE.

Q3: How often should I recalculate?
A: Recalculate whenever your weight changes significantly (5+ lbs) or your activity level changes substantially.

Q4: Why are there different activity factors?
A: Different activity levels burn different amounts of calories. More active people need higher multipliers to account for additional energy expenditure.

Q5: Can I use this for weight loss?
A: Yes, subtract 250-500 kcal from your calculated TDEE for moderate weight loss (0.5-1 lb/week).
