1. What is TDEE?

Total Daily Energy Expenditure (TDEE) represents the total number of calories your body burns in a day, including basal metabolic rate (BMR) and calories burned through physical activity. It's essential for weight management and nutrition planning.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor Equation for women:

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 first calculates your Basal Metabolic Rate (BMR), then multiplies it by your activity level to estimate total daily calorie needs.

3. Importance of TDEE Calculation

Details: Knowing your TDEE helps in creating effective weight loss, maintenance, or muscle gain plans. It provides a scientific basis for determining appropriate calorie intake for your goals.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, and select your activity level. For accurate results, use current measurements and be honest about your activity level.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between BMR and TDEE?
A: BMR is the calories your body burns at complete rest, while TDEE includes all daily activities and exercise.

Q2: How accurate is this calculator?
A: It provides a good estimate, but individual variations in metabolism may affect accuracy. Use it as a starting point and adjust based on results.

Q3: Should I eat below or above my TDEE?
A: For weight loss, eat below TDEE; for weight gain, eat above; for maintenance, match your TDEE.

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

Q5: Can men use this calculator?
A: This specific calculator uses the women's equation. Men should use a different BMR calculation: (10 × weight + 6.25 × height - 5 × age + 5).
