BMR (Basal metabolic rate) is the amount of energy expended while at rest in a neutrally temperate environment, in the post-absorptive state that is when the digestive system is inactive, which requires about twelve hours of fasting in humans. The release of energy in this state is sufficient only for the functioning of the vital organs, such as the heart, lungs, brain and the rest of the nervous system, liver, kidneys, sex organs, muscles and skin.
