Activities makes one burn calories such as walking, driving, or even talking with someone. A most interesting thing is one even burns calories even while sleeping since subtle activities are naturally happening like breathing, circulation of the blood, to name a few.
That being said, there is a need to have a minimum number of calories to be able to accomplish these basic task on a daily basis. It is possible to know this through a couple of formulas, but we need to know something else first.
The minimum calories we need when we are asleep. This number can be derived through the Harris-Benedict formula which results in the basal metabolic rate (BMR). This formula has been in existence since 1918 and twice revised to reflect a more accurate number.
There is a separate formula for men and another for women in order to get the BMR. Once done, identify your activity level represented by a number with two decimal places. After that, simply multiply your BMR with the activity number and you get the daily number of calories needed.
The resulting number of calories is for weight maintenance, thus, eating less calories will result in weight loss, eating more will gain weight.
Men burns calories more because of muscle mass as compared to women where one’s body composition is important.
