1. What is TDEE?

Total Daily Energy Expenditure (TDEE) is an estimate of how many calories you burn per day when exercise is taken into account. It's calculated by multiplying your Basal Metabolic Rate (BMR) by your activity factor.

2. How Does the Calculator Work?

The calculator uses the TDEE equation:

Where:

• \( BMR \) — Basal Metabolic Rate (calories burned at rest)
• \( Activity\ Factor \) — Multiplier based on activity level

Example: TDEE = 1500 * 1.55 = 2325 kcal/day

3. Importance of TDEE Calculation

Details: Knowing your TDEE helps with weight management - consuming fewer calories than your TDEE leads to weight loss, while consuming more leads to weight gain.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your activity level. For accurate results, use a recent BMR measurement or calculation.

5. Frequently Asked Questions (FAQ)

Q1: How do I calculate my BMR?
A: BMR can be calculated using formulas like Mifflin-St Jeor or Harris-Benedict, or measured via indirect calorimetry.

Q2: What if my activity level changes day to day?
A: Use an average activity factor or calculate TDEE separately for different days.

Q3: How accurate is this calculation?
A: It provides a good estimate but individual variations exist. Adjust based on real-world results.

Q4: Should I adjust my TDEE over time?
A: Yes, recalculate as your weight, body composition, or activity levels change.

Q5: Can TDEE be used for weight loss?
A: Yes, creating a calorie deficit of 500 kcal/day below TDEE typically results in about 1 lb/week weight loss.
