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 your body needs at complete rest)
• \( Activity\ Factor \) — Multiplier based on your activity level (1.2-1.9)

Explanation: The equation accounts for your base calorie needs plus additional calories burned through daily activities and exercise.

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 the foundation of any nutrition plan.

4. Using the Calculator

Tips: First calculate your BMR using a BMR calculator, then 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 my current weight or goal weight?
A: Always use your current weight for accurate calculations.

Q3: How often should I recalculate my TDEE?
A: Recalculate after significant weight changes (±5-10 lbs) or activity level changes.

Q4: Why are there different activity factors?
A: More active people burn more calories. Choose the level that best matches your weekly routine.

Q5: Can TDEE change day to day?
A: Yes, based on activity. TDEE represents an average - active days burn more, rest days burn less.
