Commonly Used Methods for Calculating Body Fat

Using this online calculator is the easiest way to calculate your body fat percentage. But if that’s not satisfying your curious nature and you want to calculate it manually, read further. We will explain to you about different methods and approaches to determine body fat percentage in your body composition:

1.    Calculating Body Fat Using BMI Method

BMI formula or body mass index formula is the most conventional method to calculate body fat percentage. Most of the online calculators use the same method. Even our body fat calculation is based on this approach.

The reason behind the popularity of this approach is that you need the least number of inputs and almost no tool or equipment to calculate results. All you need is:

  • A weight scale if you don’t know your weight.
  • Inch tape or measuring tape to determine your height.

Once have your weight and height noted, the other inputs are quite simple i.e., your age and gender. With all these 4 input values, you can know body fat percentage using the BMI method.

a.    Calculate Your BMI

BMI or Body Mass Index calculation is quite easy and simple. You need to know your weight in Kilograms (Kg) and Your height in meters. If you know your height in centimeters, convert it into meters by dividing it by 100. For example, if the height is 180cm then it would be 1.8 meters (180 / 100 = 1.80).

Now the BMI formula is BMI = Weight / Height2

If your weight is 80 Kg and height is 1.8 meters, then BMI: 80/ (1.8)2 = 24.7

b.    Calculate Your Body Fat Percentage

Now you have all the values you need to determine your body fat percentage. So far, we haven’t used Age and Gender in our calculation. If you are wondering where these 2 values will be required, then this is the stage where we will utilize these two values.

The calculation of body fat is different for each gender, as you can see in the body fat percentage formula below:

Women Body Fat % = (1.20 x BMI) + (0.23 x Age) – 5.4

Men Body Fat % = (1.20 x BMI) + (0.23 x Age) – 16.2

c.     Compare with Chart

Now after using these formulae, you will get a value. That’s your body fat percentage. Find that value in the given chart to know your physique category. We have given below a detailed chart where you can try to determine your physique category most accurately. If you are confused with this detailed chart, the simple and easier one is given, just below the calculator.

Remember, this method is only an estimate of body fat percentage and is not a substitute for a professional body composition analysis.

2.    Professional Methods of Calculating Body Fat

The professional method of calculating fat percentage in your body is considered the most accurate and reliable. It is used by professionals and experts like fitness trainers, physiotherapists, and health experts. Professional tools or gadgets are employed to calculate body fat percentage accurately.

In professional techniques for finding body fat, the hydrostatic pressure gauge and the subcutaneous fat test are used by experts. This method can’t be performed at home and the experts may charge you for telling you the fat percentage.

In an expert’s method to find body fat percentage, a subcutaneous fat caliper or a bioelectrical impedance instrument can be utilized by the person. Fat thickness is measured using calipers by placing it at different points of the belly.

Some experts use modern tools like bioelectrical impedance devices instead of calipers. It throws a weak current through your body and the resistance in current flow is used to determine the percentage of body fat in your body. Though it is an easier method but most of the experts claim the results are not always accurate.

What is Body Fat?

Body fat is a particular type of fat found in the human body. Fat in our body serves as an energy reserve. If you won’t eat food and won’t get carbs, fat will be used to produce energy to run the machinery of your body. But if you keep consuming excessive amounts of food then this excessive amount will be stored in your body as fats.

Fat is also used as a cushion for vital organs and saves them from jerks and collisions. Fat under your skin also serves as insulation. It saves your body from the harshness of weather and helps in maintaining the body temperature. It is estimated that up to 60-70% of an adult’s body weight can be composed of fat
