While having too much body fat can be harmful to one’s health. Moreover, having too little body fat can also be harmful. And also keeping a body fat % below, or even within, the critical body fat percentage range, is something that should be reviewed with a medical practitioner.

Body Fat Introduction

Body fat has a negative reputation, but it serves an important function. The fat you eat is stored in your body as deposits that can be used for energy, insulation, and protection. To live and operate, everyone requires some fat. Obesity-related disorders and Obesity, such as heart disease and diabetes type -2 can develop when too much body fat accumulates.

It’s not always as simple as gazing in the mirror or stepping on a scale to figure out how much body fat you have. A bodybuilder and an obese person may have the same weight, but their body fat percentages are vastly different. You can’t tell how much muscle or fat you have just by looking at your weight. However, you’ll need to figure out the fat % in your body instead.

Human Body Composition

Six elements make up more than 98 percent of the human body: calcium, oxygen, nitrogen, hydrogen, phosphorus, and carbon. Magnesium, sulfur, chlorine, sodium, and potassium account for 1% of the total. Below is a list of the 11 most vital non-trace elements. Water is the most abundant molecule in the human body. It accounts for around 65 percent of its mass, followed by lipids and proteins. Polysaccharides, Hydroxyapatite, and nucleic acids are some of the other molecules with significant mass.

The Formula for the Body Fat Calculator

With our body fat % calculator, you may assess your body composition. Remember that no calculator, no matter how sophisticated, can substitute for a trip to the doctor’s office. This result can only be used as a guide; all it can do is to notify you if your body fat % is dangerously high. But there’s no need to be concerned if it differs little from the ideal value.

You’ll need the following information to figure out your body fat percentage:

  • Measure the length from the apex of your head to the floor while standing straight. Remember, foot wears are permitted.
  • Your gender and age
  • Weigh yourself: it’s as simple as that. Check your weight in the morning, before your morning meal. And also without clothes on will give you the most accurate result.

Once you’ve gathered all of your information, enter it into the body fat calculator. Here’s the formula we use if you’re curious about how it works:

Body fat % = –44.988 + (0.503 x age) + (10.689 x gender) + (3.172 x BMI) – (0.026 x BMI2) + (0.181 x BMI x gender) – (0.02 x BMI x age) – (0.005 x BMI2 x gender) + (0.00021 x BMI2 x age)


  • BMI = weight divided by height² = kg/m²
  • Gender value: female = 1 and male = 0

Alternatives to the Body Fat Calculator of Calculating Body Fat

If you search for “ How to Work Out Your Body Fat “on your search web engine, you’ll find several techniques for calculating body fat %. Different calculators employ a variety of different formulas. Alternative ways can be found in the list below:

  • From BMI: Some algorithms allow you to compute body fat percentage directly from your BMI. They aren’t entirely correct, though, because the body fat % in 2 people with uniform BMI might vary dramatically.
  • Human fat cells have a density of 0.9 kg per liter when weighed underwater. The density of mass of lean muscle is higher, at 1.1 kilos per liter. Submerging the complete body in water can be used to know the density of the entire body if this difference is known. After making certain adjustments for air in the lungs, the body fat% can be calculated with just a limited margin of error.
  • Ultrasound can be used to determine the shape of the tissue and thus the amount of adipose tissue beneath the skin.
  • The skin fold method is a way of measuring the thickness of the layer of fat by pinching your skin in numerous predefined spots with calipers. 3 to 7 measurements are required. The disadvantage of this approach is that it only assesses the layer of adipose tissue directly beneath the skin and ignores any interior body fat.

Body Fat % vs. Body Mass Index

BMI stands for body mass index. This number differs from your body fat percentage in that it only indicates whether you are underweight, normal weight, overweight, or obese. It is unable to determine the amount of fat in your body.

While useful and simple to compute in some instances, your BMI may not be a highly trustworthy measure of your general health. If you’re an athlete, for example, you can have a low body fat % yet a high BMI due to all of your muscle. Other crucial aspects are not taken into consideration by BMI.


Your body fat percentage can be calculated by using our body fat calculator. It may also be calculated in a variety of ways, ranging from simple measurements to expensive testing. You might get different results if you attempt many of these ways. Underwater weighing or instruments like the BOD POD are the most precise. But they’re also the most expensive unless you have insurance.

It’s broken down in the muscles, producing energy and CO2. CO2 is subsequently expelled from the body via the urine or lungs.
