BMR Calculator stands for Basal Metabolic Rate. Metabolism is a set of chemical reactions happening in any body that maintain its living state.

Your BMR accounts for about 75% of calories you burn every day, depending on how active your lifestyle is. BMR tends to get lower with aging and decrease the leanner your body mass becomes.
