How to use Calorie Needs Calculator

A calorie needs calculator estimates how much energy your body may need per day based on factors such as age, sex, height, weight, and activity level.

Basic idea

BMR x activity factor = estimated daily calorie needs

Is the result exact?

No. It is an estimate. Real needs can vary based on metabolism, training, sleep, stress, and tracking accuracy.
