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 nutritional 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

Explanation: The equation calculates your Basal Metabolic Rate (BMR) first, then multiplies it by an activity factor to estimate your total daily energy needs.

3. Importance of TDEE Calculation

Details: Knowing your TDEE helps you determine appropriate calorie intake for weight loss, maintenance, or gain. It's fundamental for creating effective diet and fitness plans.

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 positive numbers for accurate results.

5. Frequently Asked Questions (FAQ)

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

Q2: How accurate is this TDEE calculation?
A: The Mifflin-St Jeor equation is considered one of the most accurate formulas for estimating calorie needs, though individual variations exist.

Q3: Should I use this calculator if I'm pregnant or breastfeeding?
A: No, this calculator is not designed for pregnant or breastfeeding women who have different nutritional requirements.

Q4: How often should I recalculate my TDEE?
A: Recalculate whenever your weight changes significantly (±5kg) or your activity level changes substantially.

Q5: Can men use this calculator?
A: This specific calculator uses the women's equation. Men should use a different formula that accounts for gender differences in metabolism.
