The human body’s daily basal metabolism is generally around 1200 to 1500kcal. Basal metabolism refers to the body’s energy requirements to maintain basic physiological activities when the body is fasting, awake and quiet, and at an ambient temperature of 18℃ to 25℃. The human body’s daily basal metabolism is generally 1200 to 1500kcal, which varies according to the patient’s age, gender, and daily activity. The formula is:The daily basal metabolic kcal for men is 66 + (13.7 x weight (kg)) + (5 x height (cm)) – (6.8 x age (years)), and for women is 655 + (9.6 x weight (kg)) + (1.8 x height (cm)) – (4.7 x age (years)). If energy intake is higher than energy expenditure it will lead to obesity. It is recommended to exercise moderately on a daily basis and control daily energy intake to help control body weight.
