The average adult’s daily basal metabolism is about 1,200 to 1,400 calories. Basal metabolism is the basic energy expenditure to maintain the body’s vital activities, and requires the body to be in a quiet and awake state to measure the energy metabolism without the influence of muscle activity, food and mental stress, environmental temperature and other factors. Normally, the daily basal metabolism of an adult is 1,200-1,400 calories. The basal metabolism of a normal person is relatively stable and is generally higher in men than in women, and higher in children and adolescents than in adults, with a gradual decrease in basal metabolism in adulthood. If you have an abnormal basal metabolism, it is recommended that you seek medical attention.
