Introduction
Teenagers require proper nutrition to support their growth and development. One crucial aspect of maintaining a healthy lifestyle is understanding the number of calories their bodies need. The Calorie Calculator for Teens is a helpful tool that allows teenagers to estimate their daily calorie intake based on various factors.
Formula
The calorie calculator utilizes the Harris-Benedict equation to estimate Basal Metabolic Rate (BMR) and then multiplies it by an activity factor to determine daily calorie needs. The formula varies slightly based on gender:
- For males: BMR = 88.362 + (13.397 * weight in kg) + (4.799 * height in cm) – (5.677 * age in years)
- For females: BMR = 447.593 + (9.247 * weight in kg) + (3.098 * height in cm) – (4.330 * age in years)
The BMR is then multiplied by an activity factor, which depends on the teenager’s physical activity level.
How to Use
- Enter your age in years.
- Select your gender (male or female).
- Input your weight in kilograms.
- Specify your height in centimeters.
- Choose your activity level from the dropdown menu.
- Click the “Calculate” button.
The calculator will display your estimated daily calorie intake.
Example
Let’s consider an example: A 16-year-old female, weighing 55 kg, with a height of 160 cm, and a moderately active lifestyle.
- Age: 16
- Gender: Female
- Weight: 55 kg
- Height: 160 cm
- Activity Level: Moderately active
Upon clicking “Calculate,” the estimated daily calorie intake for this teenager would be displayed.
