Your Basal Metabolic Rate or Basal Energy Expenditure is an approximate calculation of caloric expenditure to sustain physiological functions and processes including, but not limited to breathing, blood circulation, digestion, and intracellular growth and repair within a designated time frame of twenty-four hours.

The BMR/BEE calculation is based on the The Harris–Benedict equations revised by Mifflin and St Jeor in 1990.
