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)
• \( \text{activity factor} \) — Multiplier based on activity level

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

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 equations like Mifflin-St Jeor or Harris-Benedict, or measured through indirect calorimetry.

Q2: What if my activity level changes day to day?
A: Choose an activity factor that represents your average weekly activity level.

Q3: How accurate is this calculation?
A: It provides a good estimate but individual variations exist. For precise needs, consider professional metabolic testing.

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

Q5: Can I use this for weight loss?
A: Yes, subtract 250-500 calories from your TDEE for gradual weight loss (0.5-1 lb/week).
