BMR - Basal Metabolic Rate
Your BMR is the amount of energy in calories that your body needs to perform your basic functions such as breathing and running your nervous system, while you are at rest.
The value of the BMR does not include calories needed for digestion or exercise, even for the most moderate of movement. It only includes enough energy for the functions used to support life and the vital organs for the upkeep of the body. The BMR usually accounts for at least 70% of daily calories used.
A BMR measurement is comparable to measuring the fuel a car uses when it is idling ie. just ticking over whilst not moving or carrying any load.
This calculator provides an estimate of your BMR figure and is essential for knowing your body's absolute minimum requirement of calories needed to keep you functioning and healthy.
It forms the basis of any calorie controlled diet, since it is used in our calculation to determine how many calories you need per day to gain, maintain or lose weight.
Once you have your BMR figure, see the chart here on how to adapt it according to your lifestyle and activity level.
