1. What is TDEE for Teens?

Total Daily Energy Expenditure (TDEE) represents the total number of calories a teenager burns in a day, including basal metabolic rate (BMR) and physical activity. It's crucial for maintaining, gaining, or losing weight healthily during adolescence.

2. How Does the Calculator Work?

The calculator uses the following equations:

Where BMR is calculated using the Mifflin-St Jeor Equation:

Explanation: The equation accounts for basic metabolic needs plus activity level to estimate total daily calorie needs.

3. Importance of TDEE Calculation

Details: Understanding TDEE helps teens maintain healthy weight during growth spurts, supports athletic performance, and prevents unhealthy weight gain or loss during this critical development period.

4. Using the Calculator

Tips: Enter weight in kg, height in cm, age between 13-19 years, select gender and activity level. For accurate results, measure weight and height in the morning before eating.

5. Frequently Asked Questions (FAQ)

Q1: Is TDEE different for teens than adults?
A: Yes, teens typically have higher TDEE due to growth and development needs, even with similar activity levels.

Q2: How often should teens recalculate TDEE?
A: Every 3-6 months or after significant growth spurts or changes in activity level.

Q3: Should active teen athletes use different calculations?
A: Highly active athletes may need to use the "very active" or "extra active" multipliers and consult a sports nutritionist.

Q4: How accurate is this calculator?
A: It provides a good estimate but individual variations exist. For precise needs, metabolic testing is recommended.

Q5: Can this be used for weight loss in teens?
A: Teens should consult healthcare providers before calorie restriction as it may affect growth and development.
