1. Basal metabolic rate
The rate at which an animal body consumes oxygen when it is at rest and is not digesting a meal.

2. Basal metabolic rate (BMR)
The amount of energy liberated per unit time (metabolic rate) determined at as complete mental and physical rest as possible, in a room at a comfortable temperature, 12 hours after the last meal. The BMR of a man of average size is about 2000 food calories per day. BMR is lower in elderly subjects both on an absolute basis and per unit body weight. BMR falls by about 10% between 20 to 60 years of age. However, if the changes in body composition that comes with aging is taken into consideration, the BMR of the elderly may not be that much lower.
