Use the basal metabolic rate calculator (BMR calculator) below to determine your Basal Metabolic Rate – BMR, or the minimum number of calories you need to sustain your essential body functions.

What Is Basal Metabolic Rate – BMR
BMR or basal metabolic rate refers to the amount of energy your body uses (in calories) when you are completely at rest. In other words it is the amount of energy your body needs to keep your organs functioning and keeping you alive. This is the energy (calories) required to support life – such as body temperature, circulation, breathing, and so on. This energy does not take into account the extra energy you may require for any extra physical activities.
When you exercise your body will use more energy.
Your Basal Metabolic Rate (BMR) is affected by a number of factors:
In addition, there are other variables, such as your body’s percentage of fat, diet, and exercise habits. For example, your metabolic rate increases when you have more muscle. Muscle burns 3-5 times more calories than fat does.
As well, the body temperature will also fluctuate your BMR. For example, during sleep your body temperature drops and so does your basal metabolic rate by up to 10%. Fever will increase BMR by as much as 7%.
Stress increases basal metabolic rate and relaxation decreases it.
As well, if your body thinks you are starving (as a result of fasting or extreme dieting) it will reduce your metabolism and your BMR by up to 50%. Typically, diets below 1000 calories are perceived by our bodies as starvation.
The basal metabolic rate calculator is not suitable for children or teenagers who are still growing. As well, use this BMR calculator just as an informational tool. If you are concerned about your BMR make sure to discuss the results with your healthcare professional.
What Is RMR
RMR is an acronym for Resting Metabolic Rate and although it is the same as BMR, it is measured under conditions which are less strict and less scientifically precise. Hence the higher value for the resting metabolic rate.
Roughly, RMR values are about 15% higher than basal metabolic rate values. When you are trying to figure out your diet caloric requirements, you can safely use the RMR value.
