Basal metabolic rate refers to the minimum energy required to maintain life in a natural temperature environment in an inactive state (including the digestive system, that is, fasting for more than two hours).

The basal metabolic rate will decrease with age or weight loss, but increase with muscle gain. The unit of basal metabolic rate is "kilojoule/square meter/hour", which represents the heat emitted from the body surface per square meter per hour.

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.

Determination of basal metabolic rate is a simple and effective method for clinical diagnosis of thyroid diseases. Others, such as adrenal cortex and anterior pituitary gland, can also show a decrease in basal metabolic rate when hormone secretion is insufficient. As the body temperature rises, so does the basal metabolic rate.

Generally, the basal metabolic rate will increase by 65438 0℃ every time the temperature rises. When people are hungry or malnourished for a long time, their basal metabolism will decrease. In addition, the determination of basal metabolic rate and energy metabolic rate under different activity intensities is also the basis for formulating nutritional standards and reasonably arranging people's diets.
