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 physical activity level

Explanation: The equation calculates your basal metabolic rate first, then multiplies it by an activity factor to estimate total daily energy expenditure.

3. Importance of TDEE Calculation

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

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, and select your activity level based on your weekly exercise routine. All values must be valid positive numbers.

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

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

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

Q5: Are there limitations to this calculation?
A: This calculation may be less accurate for athletes, pregnant women, or individuals with certain medical conditions affecting metabolism.
