Basal metabolic rate basically refers to the energy expanded or the amount of calories burnt to obtain energy when a person is not indulged in any activity and is absolutely at rest. We can say that basal metabolic rate is the amount of energy required by the body to simply exist and perform its normal functions internally when at rest. The units in which the energy expenditure is measured is basically Joule/second. 

The measurement of BMR on daily basis is highly recommended. You can calculate BMR to weight loss on daily basis with the help of an online tool. With the different uses of knowing its values and the significance of being aware with the calculated value, the process becomes a little complex. The measurement is done by taking a number of different precautions. These precautions include being in a neutral state and doing no exertion. And many others. Basal metabolic rate is however, somewhat different from SMR. SMR or standard metabolic rate specifically takes the temperature surrounding the organism into consideration while BMR does not.


Metabolism refers to all the metabolic processes or all the reactions which are undergoing in the body. These processes or reactions are being carried out to support the body and sustain life.

Usually people have this misconception that if the body is not engaged in any kind of activity and specifically the physical activity, then there’s no expenditure of energy.

However, this is only a mere misconception. Even when the body is at rest, there are some energy requiring processes that the body is still performing. These processes include: breathing, respiration, blood circulation, digestion and so much more.

The energy that is being utilized or the calories that are being burnt to obtain the energy requirement is basically what the BASAL METABOLIC RATE measures or tells us.

Now whenever a person tends to go for the process of loss of weight,  maintenance of weight or even the gain of weight, the calculation of basal metabolic rate is given high importance.

This is because if one wants to lose, gain or maintain weight, the Basal metabolic rate tends to impact the burn of calories of a person. The total daily percentage expenditure of calories that is done through the basal metabolic rate is from 60 up to 75%. However, BMR is influenced by a number of different factors. (Which have been discussed below). Therefore, in a total calorie count of an individual, the calculation of and reduction of the calories burnt through BMR are also given prominent attention.


Maintenance of a healthy weight is important for a number of reasons.

You might feel absolutely comfortable in your body which is a very appreciable thing. However, the medical conditions that obesity accompanies and the life threatening diseases caused in people who are overweight are some factors which one can not overlook no matter what.

Obesity is known to be a “root disease”. Just like the roots support the tree having numerous branches, obesity also gives rise to a number of different diseases. The underlying cause of countless diseases can be obesity.

Some of these include, problems with breathing or respiratory disorders, cardiovascular diseases or the diseases which relate to the heart (even increases the chances of heart attack), diabetes, PCOS or polycystic ovaries in women, complications with delivery or during gestation, diabetes and so much more.


Bmr is dependent upon a number of factors and these factors cause the BMR values to vary.

Gender: Basal metabolic rate is around 5 to 10 percent lower in women as compared to men.

Age: As a person ages, there’s a decrease in the lean muscle mass. Due to this decrease,

Basal metabolic rate also depends upon the height and Body surface area or BSA.

Climate: surprising to many, but climate is one factor influencing BMR too. People living in temperate areas tend to have a higher BMR than in other areas. This is simply because in such climate conditions, the body expands a lot of energy in maintaining the normal body temperature.


With the significance of knowing your BMR, many people remain in a state of confusion on how to calculate the basal metabolic rate. There are many methods and formulas for the calculation. However, using an online calculator does not only save your time but it also provides you with an error free value which might not be the case in doing the calculations on your own. How to use the calculator?

The calculator basically requires a few very basic information.

  • Your gender: As BMR varies with gender, therefore the calculator requires the information about your gender to decide your BMR.
  • Height: Height is another factor as has been mentioned above. A person of the same age and gender might have a higher BMR simply because of his or her height.
  • Weight: Just like the height, weight is another important factor playing its part in BMR determination.
  • Age.
  • Your activity level: People having an active routine and those who do maximum exertion have expectedly a greater energy expenditure than people who have an office job or a sedentary life style.

After you have put all the required information on the left of the calculator into the boxes, the next step is only pressing the calculate button.

The benefit of using this calculator is that not only does it calculate the BMR but it also tells you about the amount of calories that you require per day to lose weight.

This calculator is absolutely free and highly accurate. It can provide you with your seconds just in a few seconds. Moreover, the precision of the calculated value is highly appreciable as well.
