Basal Metabolic Rate Calculator

Estimate your daily calorie needs with this interactive calculator.
Your basal metabolic rate, or BMR, is the minimum caloric requirement needed to sustain life in a resting individual and does not account for any activity. It can be looked at as being the amount of energy (measured in calories) expended by the body to remain in bed asleep all day.  Calories are burned by bodily processes such as respiration, the pumping of blood around the body and maintenance of body temperature. Obviously the body will burn more calories on top of those burned due to BMR.

BMR can be responsible for burning up to 70% of the total calories expended, but this figure varies according to factors such as gender, age, muscle mass, climate, calorie intake etc.
