1. What is TDEE?

Total Daily Energy Expenditure (TDEE) is the total number of calories you burn in a day, accounting for your basal metabolic rate (BMR) and physical activity level. It represents the calories needed to maintain your current weight.

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 body's baseline energy needs (BMR) multiplied by your activity level to estimate total daily calorie expenditure.

3. Importance of TDEE Calculation

Details: Knowing your TDEE is essential for weight management - to maintain weight, eat at TDEE; to lose weight, eat below TDEE; to gain weight, eat above TDEE.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

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

Q2: Should I recalculate my TDEE often?
A: Yes, especially if your weight, activity level, or body composition changes significantly.

Q3: What's the difference between BMR and TDEE?
A: BMR is calories burned at complete rest, while TDEE includes all daily activities and exercise.

Q4: Why are there different activity factors?
A: Different activity levels burn different amounts of calories. The factors account for this variation.

Q5: Can I use TDEE for weight loss?
A: Yes, eating 300-500 kcal below TDEE typically leads to steady weight loss (0.5-1 lb/week).
