Calculate Your BMR
Simply enter your height and weight, being careful to specify the measures (i.e feet and inches or metres and centimeters for height, and stones and pounds or kilos and grams for weight), along with your age and sex.
- If you are 6 foot and 1 inches tall, then enter 6.1
- If you are 1.83 metres tall then enter 1.83
- If you are 14 stones and 4 pounds in weight, then enter 14.4
Then hit the calculate button. We'll do some magic behind the scenes and give you your BMR in a flash.
Info on Basal Metabolic Rate (BMR)
Basal metabolic rate (BMR), and the closely related resting metabolic rate (RMR), is the amount of energy expended while at rest in a room of normal temperature.
BMR is the number of calories your body burns at rest to maintain normal body functions. It is the amount of calories per day your body burns, regardless of exercise. It changes with age, weight, height, gender, diet and exercise habits.
Basal metabolism is usually by far the largest component of total caloric expenditure. However, the Harris-Benedict equations are only approximate and variation in BMR (reflecting varying body composition), in physical activity levels, and in energy expended in the digestion of food make it difficult to estimate the dietary consumption any particular individual needs in order to maintain body weight. 2000 calories is often quoted but is no more than a guideline.
