Male basal metabolic rate =67+ 13.73* weight (kg)+5* height (cm)-6.9* age.
Basal metabolic rate refers to the energy metabolism of human body in the basic state. The basic state refers to the state that people are very quiet when they are awake and are not affected by factors such as muscle activity, environmental temperature, food and mental stress. The basal metabolism per unit time is called basal metabolic rate. If it does not exceed or fall below 15% of the normal value, it is normal.
Extended data
The energy metabolism rate of the human body when awake and extremely quiet is not affected by mental stress, muscle activity, food, environmental temperature and other factors. To measure basal metabolic rate, lie still for half an hour before breakfast in the morning (but keep awake), keep the room temperature at about 20℃, and measure it by indirect calorimetry.
The unit of basal metabolic rate is KJ/m2/h (kilojoules /m2/ hour), that is, the kilojoules of heat released per square meter of body surface per hour. The basal metabolic rate of normal people of the same sex, weight and age is very close, and the difference between the metabolic rate and the average value of about 90% people is less than 15%.
Therefore, this percentage is used as the boundary of normal value in clinic. Beyond this limit, it is considered to be abnormal basal metabolism. For example, in patients with hyperthyroidism, the basal metabolic rate is 20 ~ 80% higher than the normal value; But hypothyroidism is 20 ~ 40% lower than normal.
