1. What is TDEE?

TDEE (Total Daily Energy Expenditure) represents the total number of calories you burn each day, including basal metabolic rate (BMR) and calories burned through activity.

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 base 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, and to gain weight you need to consume more.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this TDEE calculation?
A: It provides a good estimate but individual variations exist. For best results, track your intake and weight changes over time.

Q2: What's the difference between BMR and TDEE?
A: BMR is calories burned at complete rest, while TDEE includes all daily activities and exercise.

Q3: How often should I recalculate my TDEE?
A: Recalculate whenever your weight changes significantly (5+ lbs) or your activity level changes substantially.

Q4: Why are there different activity factors?
A: Different activity levels burn different amounts of calories. Choose the one that best matches your typical week.

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