Basal metabolic rate is the amount of energy expended while at rest in a neutrally temperate environment,inthe post absorptive state(meaning that digestive system is inactive, which requires about 12 hours of fasting). The release of the energy in this stage is sufficient only for the functioning of the vital organs such as the heart, lungs, brain and the rest of the nervous systems, liver kidneys, sex oragans, muscles and skin. BMR decresses with age and with the loss of lean body mass. Increasing muscle mass increases BMR.
