1. What is TDEE?

Total Daily Energy Expenditure (TDEE) is the total number of calories you burn each day, including basal metabolic rate (BMR) and activity level. It's crucial for weight management, whether your goal is to lose, maintain, or gain weight.

2. How Does the Calculator Work?

The calculator uses the following equations:

Where:

• \( weight \) — Weight in kilograms
• \( height \) — Height in centimeters
• \( age \) — Age in years
• \( activity\_factor \) — Multiplier based on activity level

3. Importance of TDEE Calculation

Details: Knowing your TDEE helps you create an appropriate calorie plan for your fitness goals. To lose weight, consume fewer calories than your TDEE; to gain weight, consume more.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, and select your activity level. For accurate results, measure your weight and height precisely.

5. Frequently Asked Questions (FAQ)

Q1: Why use Mifflin-St Jeor instead of Harris-Benedict?
A: The Mifflin-St Jeor equation is considered more accurate for most people in modern times.

Q2: How often should I recalculate my TDEE?
A: Recalculate whenever your weight changes significantly (5+ kg) or your activity level changes substantially.

Q3: What if I'm between activity levels?
A: Choose the lower level if unsure, as people often overestimate their activity.

Q4: Does this account for body composition?
A: No, these equations don't account for muscle mass vs. fat mass. Very muscular individuals may need to adjust upwards.

Q5: How accurate is this calculator?
A: It provides a good estimate, but individual variations exist. Track your results and adjust as needed.
