Maintaining a healthy lifestyle involves various factors, and one of the essential aspects is managing your calorie intake. The Calories Requirement Calculator is a handy tool that can help you determine the number of calories your body needs on a daily basis. Whether you’re aiming to lose weight, gain muscle, or maintain your current weight, understanding your calorie requirements is crucial.
Formula
The calculator uses the Harris-Benedict equation to estimate your Basal Metabolic Rate (BMR), which is the number of calories your body needs to maintain basic functions at rest. The formula varies for men and women:
- For men: BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) – (5.677 x age in years).
- For women: BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) – (4.330 x age in years).
After calculating BMR, the calculator then takes into account your activity level to estimate your daily calorie needs. The available activity levels include sedentary, lightly active, moderately active, very active, and super active.
How to Use
Using the Calories Requirement Calculator is straightforward. Follow these simple steps:
- Age: Enter your age in years.
- Gender: Select your gender (male or female).
- Weight: Input your weight in kilograms.
- Height: Specify your height in centimeters.
- Activity Level: Choose the activity level that best describes your daily physical activity.
After filling in the required information, click the “Calculate” button. The calculator will provide you with your estimated daily calorie requirement.
Example
Let’s say a 30-year-old male with a weight of 75 kg, a height of 180 cm, and a moderately active lifestyle wants to determine his daily calorie requirement. After inputting his information and selecting “Moderately Active,” the calculator reveals that his daily calorie requirement is approximately 2689.44 calories.
