How It's Measured. Measurement of BMR is more restrictive than RMR. Measuring BMR requires a clinical procedure that takes place in a hospital or laboratory and requires the subject to spend the night. BMR is taken first thing in the morning, after eight hours of sleep and a 12 hour fast while the subject is lying down.RMR does not require a sleepover, and is measured at any time of day following a three to four hour fast.MR is taken first thing in the morning, after eight hours of sleep and a 12 hour fast while the subject is lying down.

The rate at which these processes occur is measured in calories per unit of time, and is most often given in calories per day. The term basal metabolic rate (BMR) is often confused and/or interchanged with RMR or resting energy expenditure (REE). Because men, on average, have a greater muscle mass and a lower body-fat percentage than women, they generally have a higher basal metabolic rate. 2  Age. 3  BMR is greater in childhood than in adulthood. 4  After age 20, BMR is estimated to drop about 2 percent to 3 percent each decade.
