An accurate BMR measurement requires that the person's sympathetic nervous system not be stimulated, a condition which requires complete rest. BMR is measured under very restrictive circumstances when a person is awake.Illness, previously consumed food and beverages, environmental temperature, and stress levels can affect one's overall energy expenditure as well as one's BMR. But anaerobic exercise does increase resting energy consumption. Aerobic (resistance) fitness level, a product of cardiovascular exercise, while previously thought to have effect on BMR, has been shown in the 1990s not to correlate with BMR when adjusted for fat-free body mass. Increasing muscle mass has the effect of increasing BMR. BMR generally decreases with age, and with the decrease in lean body mass. The body's generation of heat is known as thermogenesis and it can be measured to determine the amount of energy expended.BMR typically declines by 1–2% per decade after age 20, mostly due to loss of fat-free mass, although the variability between individuals is high. The basal metabolic rate accounts for about 60 to 75% of the daily calorie expenditure by individuals. Basal metabolic rate (BMR) affects the rate that a person burns calories and ultimately whether that individual maintains, gains, or loses weight. Some of those processes are breathing, blood circulation, controlling body temperature, cell growth, brain and nerve function, and contraction of muscles.
