Extremely fit men may have values of 70-80 probable that little direct guidance can be given on this, and it You burn a certain number of calories just by breathing air and digesting food. More often, it is estimated using factors such as a persons basal metabolic rate (BMR), activity level, and the thermic effect of food.
