1. What is TDEE?

TDEE (Total Daily Energy Expenditure) represents the total number of calories you burn in a day, including your basal metabolic rate (BMR) and activity level. It's crucial for weight management and nutrition planning.

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 helps with weight loss (eat below TDEE), maintenance (eat at TDEE), or weight gain (eat above TDEE). It's fundamental for personalized nutrition planning.

4. Using the Calculator

Tips: Enter your BMR (from a BMR calculator) and select your activity level. For best results, be honest about your activity level to get accurate calorie needs.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is TDEE calculation?
A: It provides a good estimate, but actual needs may vary ±10% due to individual differences in metabolism and activity.

Q2: Should I adjust my TDEE over time?
A: Yes, recalculate when your weight changes significantly or your activity level changes by more than one category.

Q3: What's the best way to determine my BMR?
A: Use a validated BMR calculator or, for most accuracy, get it measured via indirect calorimetry.

Q4: How often should I recalculate my TDEE?
A: Every 4-6 weeks if trying to lose/gain weight, or whenever your activity level changes significantly.

Q5: Can TDEE be used for athletes?
A: Yes, but highly active individuals may need to use the "extra active" multiplier or track intake/weight changes for more precision.
