This calculator will calculate your BMR (Basal Metabolic Rate). Your BMR, is the energy (measured in calories) expended by the body at rest to maintain normal bodily functions. This continual work makes up about 60-70% of the calories we use (“burn” or expend) and includes the beating of our heart, respiration, and the… (more) maintenance of body temperature. To lose 1 pound per week means that you have to consume 500 less calories daily than you burn.
