This tool calculates your daily calorie needs based on your personal information and activity level.
How to Use the Calorie Needs Calculator
To use the calorie needs calculator, enter your age, select your gender, input your current weight in kilograms, and your height in centimeters. Then, select your daily activity level from the provided options. Once you have entered all the required details, click on the “Calculate” button to receive your daily calorie needs.
How the Calculator Works
The calculator uses the Harris-Benedict formula to estimate the Basal Metabolic Rate (BMR), which represents the number of calories your body needs at rest to maintain basic physiological functions such as breathing and keeping warm.
The BMR is adjusted based on your activity level to calculate the Total Daily Energy Expenditure (TDEE), which represents the total number of calories you need to maintain your current weight. The formula used is:
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)
The TDEE is then calculated by multiplying the BMR with the selected Activity Level factor:
Sedentary: BMR x 1.2
Lightly Active: BMR x 1.375
Moderately Active: BMR x 1.55
Very Active: BMR x 1.725
Super Active: BMR x 1.9
