The Basal Metabolic Rate (BMR) Calculator estimates your Basal Metabolic Rate (BMR) - the amount of energy per unit time that you need to keep your body functioning at rest in a neutrally temperate environment. Basal metabolic rate affects the rate that a person burns calories; in other words, it affects your speed of losing and gaining weight. There are several existing estimation formulas. This formula was put forward by Mifflin - St Jeor.
