Biology
In the body, energy consumption is part of
energy homeostasis. It derived from
food energy. Energy consumption in the body is a product of the
basal metabolic rate and the
physical activity level. The physical activity level are defined for a non-
pregnant, non-
lactating adult as that person's total energy expenditure (TEE) in a 24-hour period, divided by his or her
basal metabolic rate (BMR):
