Calculating a man’s calorie requirement

The calorie requirement allows someone’s calorie requirement to be assessed based on their daily physical activity  

A man's calorie requirement

Do you weight-train, and need to know how many calories you have to consume? Or do you want to know your calorie requirement? That will depend on your basal metabolic rate and daily level of activity.

Are you very athletic? Your daily calorie requirement will be higher, because you are using more of your energy reserves. In other words, the more active you are, the more calories you will need each day.
