The Basal Metabolic Rate, BMR, is Defined As

Question

The basal metabolic rate, BMR, is defined as
A) The metabolic rate while the person is resting, fasting and awake
B) The overall average metabolism during the course of a day
C) The total metabolism averaged over a year, expressed per day
D) Metabolic rate during light exercise
E) The metabolic rate during sleep

Accepted Answer

The basal metabolic rate (BMR) is defined as the rate at which the body uses energy while at rest to maintain vital functions such as breathing and keeping warm. This is measured under very specific conditions: the person must be at rest, in a state of post-absorptive metabolism (meaning they have not eaten for at least 12 hours), awake, and in a thermally neutral environment. Choices B, C, D, and E describe different conditions or averages that do not specifically match the strict criteria for measuring BMR.
