Energy consumption

Template:Short description Template:For Energy consumption is the amount of energy used.

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):

$\text{PAL}=\frac{\text{TEE/24h}}{\text{BMR}}$
