What Is BMR?
BMR stands for basal metabolic rate and represents the number of calories you would burn in a day if you were inactive and stayed in bed all day. Our BMR calculator allows you to calculate not only the number of calories you burn when inactive but also a daily calorie figure that takes into account your lifestyle activity level. These two figures together give you a representative figure for your daily calorie intake. The BMR tool uses two formulas to calculate figures:
- Basal Metabolic Rate (BMR): This formula takes basic variables such as your age, weight and height and provides you with the number of calories you might burn each day if you were inactive for that day.
- Harris Benedict Formula: We use the original Harris Benedict Formula to calculate your daily calorie burn based upon your activity level. The calculation is fairly straight forward, taking your BMR and multiplying it by a set figure based on how active you are.
Using these equations, our calculator can provide you with an accurate gauge of your daily calorie burn. Do bear in mind that the one thing this method omits is lean body mass, which will obviously have a factor of its own. Very muscular people, for example, with receive a figure that probably under-estimates their calorie needs and very overweight people will get a calculation that over-estimates their calorie requirements.
