A person’s basal metabolic rate can be calculated by pulse rate, pulse pressure difference, or measured by a smart body fat meter. Patients who need to measure it are advised to consult a doctor. Basal metabolic rate is the rate of energy metabolism of the human body when it is in a state of wakefulness and extreme quietness, and is not affected by muscle activity, ambient temperature, food and mental stress. 1. Calculated by pulse rate and pulse pressure. Such as the following formula: basal metabolic rate = (pulse rate + pulse pressure) – 111 or basal metabolic rate = 1.28 * (pulse rate + pulse pressure) – 116. 2. Intelligent body fat meter: Some intelligent body fat meters can measure the basal metabolic rate of the human body, but there is a certain degree of error. Patients with abnormal basal metabolic rate are advised to seek timely medical attention.
