The Basal Metabolic Rate (BMR)

Wikipedia defines BMR as follows:

Basal metabolic rate (BMR), and the closely related resting metabolic rate (RMR), is the amount of energy expended daily by humans and other animals at rest. Rest is defined as existing in a neutrally temperate environment while in the post-absorptive state. In plants, different considerations apply. The release, and using, of energy in this state is sufficient only for the functioning of the vital organs, the heart, lungs, nervous system, kidneys, liver, intestine, sex organs, muscles, and skin.

In laymans terms this is the number of calories you would burn in a day with no exercise. For more information on BMR click here.
