This tool helps you calculate the daily calorie needs for a 15-year-old based on their activity level.
How to Use the Calorie Calculator
Enter your gender, weight, height, and activity level into the fields above. Then press the ‘Calculate’ button to see your estimated daily calorie needs.
How It Calculates the Results
The calculator uses the following formula:
- For males: BMR = 66 + (6.23 * weight in kg) + (12.7 * height in cm) – (6.8 * age)
- For females: BMR = 655 + (4.35 * weight in kg) + (4.7 * height in cm) – (4.7 * age)
The BMR is then multiplied by an activity factor to get the total daily calorie needs:
- Sedentary: BMR * 1.2
- Lightly active: BMR * 1.375
- Moderately active: BMR * 1.55
- Active: BMR * 1.725
Calculator Limitations
This calculator provides an estimate of daily calorie needs based on the Harris-Benedict formula. It does not take into account specific individual conditions or needs. Always consult with a healthcare provider for personalized advice.
