This tool calculates the daily calorie needs of a 13-year-old boy based on his activity level.
How the Calorie Calculator Works
This calculator estimates the daily caloric needs for a 13-year-old boy by considering their weight, height, and activity level:
- Weight: Enter the current weight in kilograms.
- Height: Enter the current height in centimeters.
- Age: This is fixed at 13 years for the purposes of this calculator.
- Activity Level: Select the level of daily physical activity from the dropdown menu.
- Body Fat Percentage: If known, this can improve the accuracy of the estimate, but it is optional.
How to Use the Calorie Calculator
- Fill out the form with the required inputs.
- Click the ‘Calculate’ button.
- The calculator will display your daily caloric needs based on the inputs provided.
Calculation Method
This calculator estimates caloric needs using the Mifflin-St Jeor Equation, which is a widely accepted method for determining Basal Metabolic Rate (BMR). The BMR is then adjusted based on the selected activity level. The general formula is as follows:
- BMR: 10 * weight (kg) + 6.25 * height (cm) – 5 * age (years) + 5
- TDEE (Total Daily Energy Expenditure): BMR * Activity Level
If body fat percentage is known, it will alter the calculation to include lean body mass for higher accuracy.
Limitations
This calculator provides an estimate and is not a substitute for professional medical advice. Exact caloric needs can vary based on numerous factors that this calculator does not take into account, including but not limited to metabolic health, genetic factors, and overall well-being. Always consult with a healthcare professional before making significant changes to diet or exercise levels.
