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

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 in kcal/day (from a BMR calculator or test) 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 results and adjust as needed.

Q2: Should I use sedentary or actual activity level?
A: Use your actual activity level for maintenance calories. Some prefer using sedentary and adding exercise calories separately.

Q3: How often should I recalculate TDEE?
A: Recalculate when your weight changes significantly (±10 lbs) or your activity level changes substantially.

Q4: Why is my TDEE different from fitness trackers?
A: Different algorithms and activity measurements can cause variations. Use this as a baseline and adjust based on results.

Q5: Can I use this for weight loss?
A: Yes, subtract 250-500 kcal from TDEE for gradual weight loss (0.5-1 lb/week). More aggressive deficits may be unsustainable.
