Because the testing conditions of measuring the RMR are less stringent than those required to measure the BMR, the RMR may be slightly less accurate than the BMR.īMR calculations involve analyzing the amount of oxygen and carbon dioxide a person breathes in and out. ![]() People do not need to fast or rest for an extended period in a controlled environment to get an estimate. ![]() ![]() The RMR estimates the number of calories a person burns during a period of inactivity.
