BMR Calculator

BMR Calculator

Are you interested to know the exact BMR of your body?

BMR stands for Basal Metabolic Rate. This calculator measures the number of calories burnt by your body during the night time or at the time when your body is at rest. BMR works differently to individuals on the basis of their body structure.

While you are sleeping at night time, your body performs vital functions that require energy. These functions include liver function, brain function, kidneys, heart function, along with other organs. In addition, the energy body’s functions to carry out these vital operations of the body are calculated with this calculator.

Furthermore, the BMR calculation of the body requires some strict measurements. During the BMR calculation, the brain function and other vital movement organs must be at rest so that the results can be accurate.  

The Harris-Benedict Equation is the most important and considered the crucial calculator while calculating your body’s BMR.

Calculation working of the calculator:

Few steps need to be performed while calculating your BMR. The calculator works on the US units and Metric units basis. Let us start with the US units section first.

BMR with US units:

1. In the first step, you have to enter the age.
2. In the next step, you have to disclose your gender.
3. Then comes the height; you have to write down your height in terms of Feet and inches.
4. Further comes the weight section. Now you have to enter your weight in terms of kilograms. Furthermore, there is an option in which you can enter your weight in pounds as well.
5. And now, in the last, you have to enter the level of exercise you do daily. 
6. Press calculate, and within no time, the answer will appear in front of you, telling you the exact amount of your BMR.

BMR with Metrics Units:

On the other hand, it is now coming towards the Metric unit base section. The step of this calculator is also simple.

1. You have to enter your age in the first section
2. In the second step, you have to elaborate on your sex, whether you are a male or female.
3. In the next step, you have to enter your height in centimeters.
4. Then you have to enter the weight in terms of kilograms.
5. In the last, now you have to tell the type of exercise you do daily.
6. Press the submit button, and the result will be shown to you on your screen.

Impact on the level of exercises:

The exercise level that you do has an impact only if your body’s muscle mass increases.

Types of exercises	Exercise Mode	Calories required to be multiplied by BMR
Sedentary	No Exercise	1.2 Calories * with your BMR rate
Light active	Very light Exercise	1.375 Calories * with your BMR rate
Moderately active	Moderate Exercise	1.55 Calories * with your BMR rate
Very active	Regular Exercise	1.725 Calories * with your BMR rate
Extra active	Very hard Exercise	1.9 Calories * with your BMR rate

Formula for BMR calculation for Men:

The working of the calculator works on a strict formula that is elaborated for your ease.

BMR formula on the basis of US units for men:

BMR (metric) = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5

BMR formula on the basis of Metrics units for men:

BMR (imperial) = (4.536 × weight in pounds) + (15.88 × height in inches) - (5 × age) + 5

Formula for BMR calculation for women:

Calculator working on the basis of the formula for women at your disposal.

BMR formula on the basis of US units for men:

BMR (metric) = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) – 161

BMR formula on the basis of Metrics units for men:

BMR (imperial) = (4.536 × weight in pounds) + (15.88 × height in inches) - (5 × age) - 161

where:

W = stands for the weight of the body in kilograms

H = stands for the height of the body in Centimeters

A = stands for the age

F = stands for the fats percentage in your body

Percentage of energy that is required by your body while sleeping:

Particulars	Percentage
Brain function	19%
Liver function	25%
Skeletal muscles	18%
Other organs	19%
Heart	7%
Kidney	10%

Metabolism variations :

Multiple variations come towards calculating the metabolism that varies from person to person based on their body structure.

Metabolism	Increase or Decrease
Increase	With an increase in body height, weight, and structure
Decrease	With the decrease in body fats or muscle tissues
Decrease	In women as compared to men
Decrease	With the decrease in age
Increase	With the increase in body temperature
Increase	With the decrease in health

Variables for BMR:

Few variables need to be considered while making any decision based on your BMR rate.

Age:

The more they age, the lesser the BMR and the calories requirements for maintaining the current physical structure.

Genetics:

The genetics of every individual affects the BMR in particular. Every human has a different body structure and attributes with which he is born.

Muscles:

The BMR level of the body increases when you exercise, and as a result, your muscle mass increases. This tends to increase your BMR overall. However, if you do light exercise, then there is no change in the BMR as your muscle mass remains the same.

Diet:

When you are starving, your actual BMR can drop to even 30%. Diet habits have too many things attached to your body’s actual BMR that needs to be addressed. When you eat a lot in a single shift, the BMR decreases. On the other hand, if your eating patterns are small and are dispersed, it increases your BMR.

Weather:

If the internal temperature of your body increases, so does your BMR. It has been said that the BMR increases to 7% with the rise in the temperature of 1.36F. This is because your body needs additional energy to cool down the internal organs.
