An accurate BMR measurement requires that the person's sympathetic nervous system is not stimulated.īasal metabolic rate is measured under very restrictive circumstances. Illness, previously consumed food and beverages, environmental temperature, and stress levels can affect ones overallĮnergy expenditure, and can affect one's BMR as revealed by gas analysis. IncreasedĬardiovascular exercise and muscle mass can increase BMR. BMR decreases with age and with the loss of lean body mass. Heart, lungs, brain and the rest of the nervous system, liver, kidneys, sex organs, muscles and skin. The release of energy in this state is sufficient only for the functioning of the vital organs, such as the Is inactive, which requires about twelve hours of fasting in humans). Obviously the body will burn more calories on top of those burned due to BMR.īasal metabolic rate (BMR) is the amount of energy expended while at rest in a neutrally temperate environment, in the post-absorptive state (meaning that the digestive system BMI (body mass index), which is based on the height and weight of a person, is an inaccurate measure of body fat content and does not take into account muscle mass, bone density, overall body.
