The formula for calculating the basal metabolic rate is the patient’s basal metabolic rate % = (pulse rate + pulse pressure difference) – 111 (Gale method). If the basal metabolic rate is to be done, it is better to go to the hospital to be more accurate, because the basal metabolic rate has strict requirements before measurement, that is, in the early morning before breakfast, and to rest for more than half an hour, and the room temperature should be maintained at 20 ℃ or less, so that it may be more accurate. The basal metabolic rate is usually related to gender and age, normally the basal metabolic rate of men is higher than that of women, and the younger the age, the higher the basal metabolic rate.
