Calories are the unit of measurement for the energy that the human body gets from the nutrients it consumes, and it enables it to perform the main vital functions to supply the body with the necessary energy while avoiding obesity. The calories needed by a person are calculated by calculating the person's main metabolic rate, and multiplying the rate by the factor of the person's physical activity.

A man who weighs 80 kilograms and does a lot of effort needs 50% of the 1920 calories, that is, to 960 additional calories, meaning that the total of what he needs from calories per day is: 1920 basic energy + 960 calories for effort = 2880 calories Daily, as for the calculation of 70%, he needs additional 1,344 calories, meaning that the total of what he needs per day is: 1920 + 1344 = 3264 calories per day.
