The human body’s daily basal metabolism is generally about 1,200 to 1,500 kcal. Different factors such as age, gender and body size lead to large differences in basal metabolism among different people. In general, the basal metabolism of a normal adult human body is generally about 1,200 to 1,500 kcal per day. The basal metabolism of males is generally higher than that of females, but it is significantly higher in females during pregnancy. Taller, more muscular people usually have higher basal metabolism levels. Basal metabolism also increases in heat, cold, and stress. Metabolism is regulated by endocrine hormones, such as thyroid hormones, adrenal hormones, glucocorticoids, etc. Endocrine disorders can also affect basal metabolism. Consult your doctor for details.
