Basal Energy Expenditure - also known as basal metabolic rate (BMR) or (incorrectly) as resting metabolic rate (RMR) - is the minimum number of calories your body needs at rest to fuel its metabolic activity, for example to maintain functions such as heart beat, breathing and temperature. (A kilocalorie, commonly referred to as a calorie, is equivalent to approximately 4.1868 kilojoules.)
