Question

Quizplus · Accepted Answer

Basal metabolic rate (BMR) refers to the amount of energy expended while at rest in a neutrally temperate environment, in the post-absorptive state (meaning that the digestive system is inactive, which requires about 12 hours of fasting in humans). The energy spent is to maintain the body's basic physiological needs, such as cellular metabolism, respiration, and maintaining body temperature, not for food processing, psychological needs, or physical activity.
