1. What is TDEE for Teenagers?

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

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor equation for BMR and multiplies by activity factor:

Where:

• \( BMR \) — Basal Metabolic Rate (kcal/day)
• \( activity\_factor \) — Multiplier based on activity level (1.2-1.9)

BMR Calculation:
For males: \( (10 \times weight\:kg) + (6.25 \times height\:cm) - (5 \times age) + 5 \)
For females: \( (10 \times weight\:kg) + (6.25 \times height\:cm) - (5 \times age) - 161 \)

3. Importance of TDEE Calculation

Details: Understanding TDEE helps teenagers maintain proper nutrition during growth spurts, supports athletic performance, and prevents unhealthy weight gain or loss.

4. Using the Calculator

Tips: Enter accurate weight and height measurements. Select activity level honestly - overestimation is common. Remember TDEE changes with growth and activity patterns.

5. Frequently Asked Questions (FAQ)

Q1: How often should TDEE be recalculated?
A: Every 2-3 months or after significant changes in weight, height, or activity level.

Q2: Is TDEE different for growing teenagers?
A: Yes, teenagers often have higher TDEE than adults due to growth requirements and typically higher activity levels.

Q3: What if I'm very athletic?
A: Competitive 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, professional assessment is recommended.

Q5: Should I eat below my TDEE to lose weight?
A: Teenagers should consult a healthcare provider before restricting calories, as proper nutrition is crucial for development.
