1. What is the TDEE Formula?

The TDEE (Total Daily Energy Expenditure) formula estimates the total number of calories your body burns in a day, including basal metabolic rate and physical activity. It provides a comprehensive assessment of your daily energy needs for weight management.

2. How Does the Calculator Work?

The calculator uses the TDEE equation:

\[ TDEE = (10 \times weight + 6.25 \times height - 5 \times age - 161) \times activity\ factor \]

Where:

\( weight \) — Body weight in kilograms (kg)
\( height \) — Height in centimeters (cm)
\( age \) — Age in years
\( activity\ factor \) — Multiplier based on activity level (1.2-1.9)

Explanation: The equation calculates your basal metabolic rate first, then multiplies it by an activity factor to account for your daily physical activity level.

3. Importance of TDEE Calculation

Details: Accurate TDEE estimation is crucial for weight management, whether your goal is weight loss, weight maintenance, or muscle gain. It helps determine appropriate calorie intake for your specific needs.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, and select your activity level. All values must be valid (weight > 0, height > 0, age between 1-120).

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between BMR and TDEE?
A: BMR (Basal Metabolic Rate) is the calories your body burns at complete rest, while TDEE includes all daily activities and exercise.

Q2: How accurate is this TDEE formula?
A: This formula provides a good estimate for most people, but individual variations in metabolism may affect accuracy. It's best used as a starting point.

Q3: Should I use metric or imperial measurements?
A: This calculator uses metric measurements (kg for weight, cm for height). Convert imperial measurements if needed (1 kg = 2.2 lbs, 1 cm = 0.39 inches).

Q4: How often should I recalculate my TDEE?
A: Recalculate when your weight changes significantly, activity level changes, or every 3-6 months to account for metabolic changes.

Q5: Can TDEE help with weight loss goals?
A: Yes, creating a calorie deficit of 500-1000 calories below your TDEE typically results in 0.5-1 kg of weight loss per week.
