Basal Metabolic Rate(BMR) Calculator
Calculate Basal Metabolic Rate! This BMR calculator provides an estimate of your Basal Metabolic Rate (BMR). Your BMR is the the amount of calories that you burn while you are at complete rest and not digesting any food. In other words, BMR represents the amount of calories your body must burn to simply keep itself alive without accomplishing anything else.
BMR calories are burned to sustain the function of vital organs like your heart, brain, nervous system, lungs, kidneys, liver, muscles, and skin, but BMR does not include calories burned to support physical activity or digestion of food.

FAQs:
♣ Basal metabolic rate (BMR):"Basal metabolic rate (BMR) is the minimal rate of energy expenditure per unit time by endothermic animals at rest.It is reported in energy units per unit time ranging from watt (joule/second) to ml O2/min or joule per hour per kg body mass J/(h·kg). Proper measurement requires a strict set of criteria be met. These criteria include being in a physically and psychologically undisturbed state, in a thermally neutral environment, while in the post-absorptive state (i.e., not actively digesting food). In bradymetabolic animals, such as fish and reptiles, the equivalent term standard metabolic rate (SMR) is used. It follows the same criteria as BMR, but requires the documentation of the temperature at which the metabolic rate was measured. This makes BMR a variant of standard metabolic rate measurement that excludes the temperature data, a practice that has led to problems in defining "standard" rates of metabolism for many mammals."
Basal metabolic rate (BMR) is the total number of calories that your body needs to perform basic, life-sustaining functions. These basal functions include circulation, breathing, cell production, nutrient processing, protein synthesis and ion transport. You can calculate basal metabolic rate using a mathematical formula.
Definition of Basal Metabolic Rate vs. Resting Metabolic Rate
Many weight loss and exercise guides use the terms basal metabolic rate and resting metabolic rate (RMR) interchangeably.
And the fact is that these two terms are very similar. But there is a slight difference in the definition of BMR and the definition of RMR that is helpful to understand.
Definition of Basal Metabolic Rate. A measurement of the number of calories needed to perform your body's most basic (basal) functions, like breathing, circulation and cell production. BMR is most accurately measured in a lab setting under very restrictive conditions.
Definition of Resting Metabolic Rate. A measurement of the number of calories that your body burns at rest. Resting metabolic rate is usually measured in the morning before you eat or exercise and after a full night of restful sleep.
As you can see, the definitions of RMR and BMR are almost identical. Your resting metabolic rate should be an accurate estimate of your basal metabolic rate. Because the terms are similar, many fitness and weight loss experts use both terms to describe the same thing.
But the term "resting metabolic rate" is more common.
♣ Equations:
This calculator is based on the widely used and accepted Harris-Benedict equations for BMR. They are shown below:
Male (metric): BMR = (13.75 x WKG) + (5 x HC) - (6.76 x age) + 66
Male (imperial): BMR = (6.25 x WP) + (12.7 x HI) - (6.76 x age) + 66
Female (metric): BMR = (9.56 x WKG) + (1.85 x HC) - 4.68 x age) + 655
Female (imperial): BMR = (4.35 x WP) + (4.7 x HI) - 4.68 x age) + 655
where
HC = Height in Centimetres
HI = Height in Inches
WKG = Weight in Kilograms
WP = Weight in Pounds
The equations above are exactly the same as those used for our Daily Caloric Expenditure Calculator, except that the "Activity Level Factor" that is used for the Daily Caloric Expenditure Calculator has been removed here. In the Daily Caloric Expenditure Calculator, BMR was multiplied by the "Activity Level Factor" to account for daily physical activity levels and the thermic effect of food (thereby providing an estimate of the total amount of calories you burn in a day), but these factors are not a consideration when determining BMR. The difference between the equations shown above and those on the Daily Caloric Expenditure Calculator is illustrative of the actual meaning of BMR.
How to Calculate Basal Metabolic Rate:If you want to lose weight, it's helpful to calculate your BMR. You can either find the number using a formula designed by scientists, you can get it tested in a lab, or you can use an online calculator. There is no method that is perfectly accurate, but a lab test will probably give you the best estimate.
But since lab tests can be costly, many dieters and exercisers use one of the other two methods to determine basal metabolic rate and/or the total number of calories they burn each day.
- Use an online BMR calculator. Put your height, weight, and age into our online calculator to find your basal metabolic rate with the addition of daily activity. The calculator provides you with an estimate of the total number of calories you burn each day.
- Calculate your own BMR. The Harris-Benedict Equation is often used to estimate basal metabolic rate.
Men: BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) - (5.677 x age in years)
Women: BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) - (4.330 x age in years)
♣ How to Change Your Basal Metabolic Rate:Your BMR is determined by a combination of factors. These include genetic factors, age, gender and body composition. There's not much you can do to control genetics, age or gender. But you can change your body composition to boost metabolism.So how do you change your BMR? Build muscle! Even when your body is at rest, lean muscle mass will burn more calories than fat. And you don't even have to be a bodybuilder to see benefits.Several studies have shown that after just a few weeks of resistance training you may be able to see a 7-8% increase in resting metabolic rate.
♣ How to Use BMR for Weight Loss:Now that you understand BMR you can use the number to help you lose weight. Your basal metabolic rate combined with two other factors can give you an idea of the total number of calories you burn each day.
Total Calories Burned Each Day:
Basal metabolic rate: 60-75% of total calories burned each day
Activity thermogenesis (non-exercise movement and exercise) 15-30% of total calories burned each day
Thermic effect of food (calories burned from eating and digestion) 10% of total calories burned each day
If you can burn more calories than you eat, you will create a calorie deficit. A calorie deficit of 500-1000 calories per day should result in a 1-2 pound weight loss per week.
