1. What is Total Energy Expenditure?

Total Energy Expenditure (TEE) represents the total number of calories your body burns in a day, including basal metabolic rate and physical activity. It's a crucial measure for weight management and nutritional planning.

2. How Does the Calculator Work?

The calculator uses the TEE equation:

Where:

• \( BMR \) — Basal Metabolic Rate (kcal/day)
• \( activity\_factor \) — Multiplier based on activity level

Explanation: The equation multiplies your basal metabolic rate by an activity factor that accounts for your daily physical activity level.

3. Importance of TEE Calculation

Details: Accurate TEE estimation is essential for weight management, athletic training, and nutritional planning. It helps determine appropriate calorie intake for weight loss, maintenance, or gain.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your appropriate activity level. BMR can be calculated using various formulas (Harris-Benedict, Mifflin-St Jeor, etc.) based on age, gender, weight, and height.

5. Frequently Asked Questions (FAQ)

Q1: What are typical activity factor values?
A: Sedentary: 1.2, Lightly active: 1.375, Moderately active: 1.55, Very active: 1.725, Extra active: 1.9

Q2: How accurate is this calculation?
A: While useful for estimation, individual variations in metabolism and activity patterns mean actual TEE may differ by ±10-20%.

Q3: Should I use this for weight loss planning?
A: Yes, but consider it a starting point. Adjust based on actual results and consult with healthcare professionals for personalized advice.

Q4: How often should I recalculate my TEE?
A: Recalculate when your weight changes significantly, activity level changes, or every 3-6 months for accuracy.

Q5: Are there other factors that affect TEE?
A: Yes, factors like thermic effect of food, non-exercise activity thermogenesis (NEAT), and individual metabolic variations also contribute to total energy expenditure.
