1. What is the Total Energy Expenditure Formula?

The Total Energy Expenditure (TEE) formula calculates the total number of calories a person burns in a day. It is the sum of Basal Metabolic Rate (BMR), Thermic Effect of Food (TEF), and Physical Activity Energy Expenditure (PAEE).

2. How Does the Calculator Work?

The calculator uses the TEE equation:

Where:

• \( BMR \) — Basal Metabolic Rate (kcal/day)
• \( TEF \) — Thermic Effect of Food (kcal/day)
• \( PAEE \) — Physical Activity Energy Expenditure (kcal/day)

Explanation: BMR represents the calories burned at rest, TEF accounts for energy used in digesting food, and PAEE includes calories burned through physical activity.

3. Importance of TEE Calculation

Details: Accurate TEE estimation is crucial for weight management, designing nutrition plans, and understanding daily energy requirements for maintaining, losing, or gaining weight.

4. Using the Calculator

Tips: Enter BMR, TEF, and PAEE values in kcal/day. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How is BMR different from TEE?
A: BMR represents only the energy needed for basic bodily functions at rest, while TEE includes all energy expenditure including physical activity and food digestion.

Q2: What is a typical TEF value?
A: TEF typically accounts for about 10% of total daily energy expenditure, but can vary based on meal composition and frequency.

Q3: How can PAEE be measured accurately?
A: PAEE can be estimated using activity trackers, heart rate monitors, or through detailed activity logs with established MET values.

Q4: Why is TEE important for weight management?
A: Understanding TEE helps determine appropriate calorie intake for weight maintenance, loss, or gain based on energy balance principles.

Q5: Can TEE vary day to day?
A: Yes, TEE can fluctuate based on activity levels, diet composition, stress, sleep quality, and other metabolic factors.
