1. What is TDEE?

TDEE (Total Daily Energy Expenditure) represents the total number of calories you burn in a day, including basal metabolic rate (BMR) and physical activity. It's used to determine maintenance calorie needs for weight management.

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

3. Importance of TDEE Calculation

Details: Knowing your TDEE helps with weight management - consuming more than TDEE leads to weight gain, consuming less leads to weight loss, and matching TDEE maintains weight.

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 do I calculate my BMR?
A: Use a BMR calculator that considers your age, gender, weight, and height. Popular equations include Mifflin-St Jeor and Harris-Benedict.

Q2: What if my activity varies day to day?
A: Choose an average activity level or calculate separate TDEEs for different days of the week.

Q3: How accurate is TDEE estimation?
A: It's an estimate. Individual variations in metabolism can cause actual TDEE to differ by ±10-15%.

Q4: Should I adjust my TDEE over time?
A: Yes, recalculate when your weight changes significantly or your activity level changes.

Q5: Can TDEE be measured directly?
A: Indirect calorimetry can measure resting metabolic rate, but full TDEE measurement requires specialized equipment.
