1. What is TDEE?

Total Daily Energy Expenditure (TDEE) represents the total number of calories your body burns in a day. It consists of four main components: Basal Metabolic Rate (BMR), Thermic Effect of Food (TEF), Exercise Energy Expenditure (EEE), and Non-Exercise Activity Thermogenesis (NEAT).

2. How Does the Calculator Work?

The calculator uses the TDEE equation:

Where:

• \( BMR \) — Basal Metabolic Rate (calories burned at rest)
• \( TEF \) — Thermic Effect of Food (≈10% of total calories)
• \( EEE \) — Exercise Energy Expenditure (calories from structured exercise)
• \( NEAT \) — Non-Exercise Activity Thermogenesis (calories from daily movement)

Explanation: This comprehensive calculation provides a detailed breakdown of your total daily energy expenditure, helping you understand how different activities contribute to your overall calorie burn.

3. Importance of TDEE Calculation

Details: Understanding your TDEE is crucial for weight management, whether your goal is weight loss, maintenance, or muscle gain. It helps you determine the appropriate calorie intake for your specific goals and activity level.

4. Using the Calculator

Tips: Enter your BMR (calculated separately), estimated EEE from exercise activities, and estimated NEAT from daily non-exercise movements. All values must be in kcal/day and greater than or equal to zero.

5. Frequently Asked Questions (FAQ)

Q1: How do I calculate my BMR?
A: BMR can be estimated using formulas like Mifflin-St Jeor or Harris-Benedict, which consider age, weight, height, and gender. Many online calculators are available for this purpose.

Q2: What's the difference between EEE and NEAT?
A: EEE refers to calories burned during structured exercise (gym workouts, running, sports), while NEAT includes calories burned through daily activities (walking, fidgeting, household chores).

Q3: Why is TEF estimated at 10%?
A: The thermic effect of food typically accounts for about 10% of total energy expenditure, though this can vary slightly based on macronutrient composition of your diet.

Q4: How accurate is this TDEE calculation?
A: While this provides a good estimate, individual variations exist. For precise measurements, professional metabolic testing may be required.

Q5: How often should I recalculate my TDEE?
A: Recalculate when your weight changes significantly, activity level changes, or every 4-6 weeks to account for metabolic adaptations.
