Adult men usually consume about 1500 to 2500 calories a day, the specific consumption of my body surface area, body type, gender, endocrine, environment, physical activity and disease and other factors. 1. Body surface area and body type: basal metabolic energy consumption is basically proportional to the body surface area; secondly, the basal metabolism of tall and thin people is higher than that of short and fat people. 2. Gender: the consumption of energy in the basal metabolism part is about 5% to 10% higher in men than in women, but there are special cases, such as women’s basal metabolism consumption will increase significantly during pregnancy. 3. Endocrine: when the adrenal gland, thyroid gland, pituitary gland and other secretion of hormone imbalance, will also affect the basal metabolism consumption of energy level. 4. Environment: The heat or cold of the external environment can increase the level of basal metabolism. 5. Disease: Fever, for example, can increase the basal metabolic rate significantly. 6. Physical activity level: If more physical labor is performed in a day, the calories consumed can even exceed 4000 to 5000 calories.
