The formula for calculating basal metabolic rate in women is: BMR = pulse beats per minute + pulse pressure difference – 111 (simple algorithm). Basal metabolic rate (BMR) is the number of calories produced per square meter of body surface area per hour by the body in the basal state (quiet and fasting), and oxygen consumption is usually used as an indicator in clinical practice. The formula for calculating basal metabolic rate in women is the same as in men: BMR = pulse beats per minute + pulse pressure difference – 111 (a simple algorithm). In a healthy state, the body’s physiological activities are relatively stable, and the basal metabolic rate is maintained in a normal range. When measuring the basal metabolic rate, it is necessary to pay attention to the following: a few days before the test, should stop taking drugs that affect the function of the thyroid gland, so as not to affect their own basal metabolic rate; the day before the test, fasting after dinner, the next morning no longer eat, drink a small amount of water, minimize the activities, empty the bladder, because eating also affects the basal metabolic rate of a person. 30 minutes before the test lying down to rest, relax the collar button, pants belt, keep the environment quiet, fever does not carry out this test.
