How Does a Calorie Calculator Work – Simple Guide

This tool helps you calculate the number of calories you need daily based on your personal details and activity level.







How to Use the Calorie Calculator

Enter your age, weight, height, and select your gender and activity level in the fields provided. Click the “Calculate” button to find out your daily calorie needs.

How It Calculates the Results

The Calorie Calculator uses the Mifflin-St Jeor Equation to calculate Basal Metabolic Rate (BMR). The equation is as follows:

For men: BMR = 88.362 + (13.397 × weight in kg) + (4.799 × height in cm) – (5.677 × age in years)

For women: BMR = 447.593 + (9.247 × weight in kg) + (3.098 × height in cm) – (4.330 × age in years)

Then, the BMR is multiplied by an activity factor that corresponds to your activity level to calculate daily calorie needs.

Limitations

Please note that while the Calorie Calculator provides a good estimate, it might not be perfectly accurate for everyone. Factors like muscle mass, health conditions, and metabolism variations can affect the actual calorie requirements.
