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 an 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 (1.2-1.9)

Explanation: The equation accounts for your basic metabolic needs plus additional calories burned through physical activity.

3. Importance of TDEE Calculation

Details: Knowing your TDEE is essential for weight management - to lose weight you need to consume fewer calories than your TDEE, to gain weight you need to consume more.

4. Using the Calculator

Tips: Enter your BMR in kcal/day (use a BMR calculator if unknown) and select your activity level. All values must be valid (BMR > 0).

5. Frequently Asked Questions (FAQ)

Q1: How accurate is TDEE calculation?
A: It provides a good estimate but individual variations exist. Track your progress and adjust as needed.

Q2: Should I eat at my TDEE to maintain weight?
A: Yes, consuming calories equal to your TDEE should maintain your current weight.

Q3: How often should I recalculate my TDEE?
A: Recalculate whenever your weight changes significantly or your activity level changes.

Q4: What's the best way to determine my activity factor?
A: Be honest about your exercise habits. When in doubt, choose a lower activity level.

Q5: Can TDEE change throughout the week?
A: Yes, if your activity levels vary significantly day-to-day, you might want to calculate separate TDEEs for different days.
