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 and physical activity. For girls under 18, we use the Schofield equation to estimate TDEE.

2. How Does the Calculator Work?

The calculator uses the Schofield equation for girls under 18:

\[ TDEE = (16.969 \times weight + 1.618 \times height - 413.5) \times activity\ factor \]

Where:

\( weight \) — Body weight in kilograms (kg)
\( height \) — Height in centimeters (cm)
\( activity\ factor \) — Multiplier based on activity level

Activity Factors:

Sedentary (little/no exercise): 1.2
Lightly Active (light exercise 1-3 days/week): 1.375
Moderately Active (moderate exercise 3-5 days/week): 1.55
Very Active (hard exercise 6-7 days/week): 1.725
Extremely Active (very hard exercise, physical job): 1.9

3. Importance of TDEE Calculation

Details: Knowing your TDEE is essential for weight management, whether your goal is weight loss, maintenance, or gain. It helps determine appropriate calorie intake for healthy growth and development in adolescents.

4. Using the Calculator

Tips: Enter weight in kg, height in cm, and select your activity level based on your weekly exercise routine. All values must be valid (weight > 0, height > 0).

5. Frequently Asked Questions (FAQ)

Q1: Why use the Schofield equation for girls under 18?
A: The Schofield equation is specifically validated for pediatric and adolescent populations and provides accurate estimates for this age group.

Q2: How often should I recalculate my TDEE?
A: Recalculate every 3-6 months or whenever there are significant changes in weight, height, or activity level.

Q3: Is this calculator suitable for boys under 18?
A: No, this calculator uses the equation specifically for girls. Boys require a different equation.

Q4: What if I'm between activity levels?
A: Choose the activity level that best matches your average weekly routine, or use an intermediate value if needed.

Q5: How accurate is this calculation?
A: While the Schofield equation provides a good estimate, individual variations exist. For precise needs, consult a healthcare professional.
