Energy is consumed by the body whether at rest (sleeping) or not performing any task. Basal metabolic rate (BMR) is the amount of energy consumed per unit time by the endothermic organisms at rest in a moderate temperate atmosphere and when the metabolic system is inactive.
In other words this is the calculation of energy consumed by an organism at rest just like gas consumed by a car while parked. In the state of rest, the energy is mainly used by the main organs like kidneys, liver, heart, skin, and lung.
Measuring basal metabolism requires strict measures to be met. For an accurate measurement of BMR rate a person’s sympathetic nervous system must be inactive means the person must be completely at rest. Basal metabolism is the largest component that consumes most of the calories. Depending on the activity, BMR caloric daily need is between 1.2 and 1.9.
There are three equations most abundantly used for BMR calculations which are stated below:
BMR = 10W + 6.25H - 5A + 5
BMR = 10W + 6.25H - 5A - 161
BMR = 13.397W + 4.799H - 5.677A + 88.362
BMR = 9.247W + 3.098H - 4.330A + 447.593
BMR = 370 + 21.6(1 - F)W
W= Weight measured in kg
H= Height measured in cm
A= Age of the person
F= Percentage of body fat
The Harris-Benedict Equation was the earliest equation introduced and used for six years from 1984 to 1990. After that, the Mifflin-St Jeor Equation was presented and was more precise than the revised equation of Benedict. The Katch-McArdle Formula is a slightly different formula and uses lean body mass which the other equations don’t use.
Also known as metabolism calculator. This tool is developed to easily check the Basal metabolic rate of an individual.
All you have to do is just put the information into the boxes provided in the tool and the tool with show you the Basal metabolic rate (calories burned and needed per day). To calculate BMR accurately you need to insert correct readings of height, weight, and exact age.
You can measure your height, weight, and age in any unit as there are different unit options provided in the tool. Our best accurate BMR calculator is fast and reliable.
You don’t have to fast for almost 12 hours for an inactive sympathetic nervous system. Just add the appropriate details in the boxes and hit the “calculate” button and there you go with the results.
Basal metabolic rate calculator can be used to reduce weight. Weight loss is when a person’s calorie intake is less than the calories burned per day. Initially, the first thing to know is bmr to lose weight.
Know the actual calories you burn each day and the calories you need. Use our accurate bmr calculator.
Maintain healthy weight according to your height and age by having proper knowledge about your consumption.
You can use BMI (body mass index) calculator as well to know that you fall in the healthy weight category or not.
There are different aspects that are involved when BMR is discussed which involves diet, climate and other elements. Just like individuals living in cold climatic regions have more BMR as they have to release more energy to maintain their constant body temperature. There are several other variables, medically proven and some of them are discussed below:
Gender: As compared to women, men have a low percentage of body fat and higher lean muscle mass and due to this men have higher BMRs value than women. Our BMR calculator is for men and women.
Genetics: Hereditary traits from parents also affect BMR. Some person has low metabolism and others have high metabolism according to their genes.
Age: a person’s BMR decreases as they get old. After the age of 20 the metabolism rate decreases by approx. 2% every 10 years.
Body Surface Area: The surface area of the body involves the height and weight of a person. The larger the surface area more the metabolic rate and vice versa.
Percentage of Body fat: The higher the percentage of body fat the lower will the BMR. This is one main reason men have a higher metabolic rate than women.
Diet: starvations' diet plans reduce 30% of the BMR value of an individual. Low-calorie intake and weight loss diet can typically cause a reduction in an individual’s BMR value by 20%. Diet is ultimately directly proportional to metabolic rate.
Physical Exercise: Physical activity not only burns calories but also increases BMR of a person. This increase is due to the increase in lean body mass as a result of exercise.
Pregnancy: due to the separate livelihood of fetus in a pregnant woman tend to increase BMR value. This is one reason pregnant women eat more than usual. Moreover, menopause also causes a decrease or increases BMR relying on hormonal change.
There are some elements involved like height, weight and other aspects with respective units to calculate BMR manually.
Here are quick steps to calculate BMR manually for both men and women:
Step 1: Measure Height
Measure your height in inches. Multiply by 2.54 to convert them into centimeters. Just like if you are 71 inches tall then 71 into 2.54 equals 180.34cm.
Step 2: Measure Weight
Use a digital weighing machine or any other machine to weigh yourself in kg. If you know your weight in pounds then you have to convert it by dividing pounds from 2.2.
Step 3: Calculations
After getting height and weight you can calculate your BMR by using any simple calculator.
The formulas are different for both men and women. However, you can use the online BMR calculator for men and BMR calculators for women to calculate easily.
For men: BMR = (height in cm x 6.25) + (weight in kg x 9.99) - (age x 4.92) + 5.
For women: BMR = (height in cm x 6.25) + (weight in kg x 9.99) - (age x 4.92) - 161.
Add values calculated above, putting them into the equation and get the appropriate results by doing simple Math.
