How is Body Fat Percentage Measured?

Why is the percentage of body fat important? If your objective is to lose weight, you might be tempted to check your progress using a straightforward bodyweight scale, but your body fat percentage will tell you more than the scale.

Fat loss, not just weight loss, should be your objective when you’re trying to lose weight intentionally, improve your health, or get more fit. The lean mass, or fat-free mass, that your body need should remain. Bone, blood, connective tissue, organs, and muscle all make up lean mass.

You may determine how well your fitness or weight loss program is working for you by monitoring changes in your body fat percentage. This will allow you to shed fat while preserving lean mass.


Other Methods of Determining Body Fat Percentage

Body composition, or the ratio of your lean to fat mass, can be calculated in a variety of methods. One of them is using a calculator to determine body fat.

Body Fat Calculator

For women, the formula begins with a simple weight calculation:

  • (Total bodyweight x 0.732) + 8.987

The tool uses fractions of each body measurement to estimate your body fat percentage.

For men, the formula begins with a different weight calculation:

  • (Total bodyweight x 1.082) + 94.42

The tool uses a fraction of the weight measurement to estimate your body fat percentage.

The most accurate way to determine body fat percentage is not via a body fat calculator. It is, nevertheless, the easiest system to use. Consequently, you might be able to use it more frequently.

You can track trends in your development if you measure at the same time every day and use the same equipment (the same tape measure and online calculator), which can be much more helpful in evaluating your fitness gains than a single measurement.


Skin Caliper Measurements

Your body is pinched by skin calipers to determine how much fat is present. For measuring body fat percentage, employing calipers can be more precise than using a calculator, however accuracy depends on the user’s level of expertise.


Bioelectrical Impedance (BIA)

You receive an immediate and quick body fat percentage result. Even though this method is practical, some elements, including hydration level, can affect the accuracy of the outcome.


DeXA Scanning

The gold standard for calculating body fat percentage is gradually evolving to be whole-body scanning. The test is mostly accurate since it is typically carried out in a medical setting by highly qualified technicians. The DeXA exam is frequently expensive and could not be offered where you live.

Hydrostatic Weighing

The most accurate way to determine body fat percentage has long been the submersion technique. However, it necessitates holding one’s breath while completely submerged in a tank of water.

The stamina needed for hydrostatic weighing can be difficult for many people. Finding a place to conduct the test can be challenging as well.


How to Cut Back on Body Fat

Many people desire to reduce weight at some point because many cultures place such a high emphasis on being slender. However, everyone shouldn’t make losing weight their main objective.

Make sure to incorporate up to two or three sessions each week of high-intensity interval training into your regimen. You should also do easy, moderate workouts in addition to cardio.


Your Strength Training Program

Cardio is frequently the main weight-loss strategy, but building more muscle will increase your ability to burn fat. Since muscle has a higher metabolic activity than fat, having more of it increases your daily caloric expenditure. To add lean muscle tissue and burn more fat, all you need to do is strength exercise a few times per week.


Lifestyle Factors

Since stress hormones can cause weight gain, managing your stress levels and getting enough sleep are essential to maintaining a healthy weight. Taking care of yourself will help you stay motivated to prepare healthy meals and keep the energy required to finish important workouts.
