Choose from several body fat measurement methods, including the US Navy Method, skinfold caliper measurements, and BMI calculations that best suit your needs. Track your fitness progress effectively and get valuable health insights.
Body composition is an important factor in overall health, measuring the different proportions of muscle, fat, bone, water, and other tissues in your body. An ideal body composition comes with a higher percentage of muscle mass and lower body fat. The body fat percentage can not determine your overall health condition. Rather it provides valuable insights (inflammation levels, overall fitness, hormonal balance, etc) into your health conditions.
Maintaining a healthy body composition with a balance of lower body fat and higher muscle mass provides various benefits including:
Knowing your body fat percentage can help you:

There are different methods to estimate the body fat percentage, each technique having varying degrees of accuracy. Below we have discussed a few of them that are convenient to use.
Body fat percentage is the total mass of the fat divided by the total mass of the body. And then multiply the result by 100.
\(BFP = \frac{\text {Mass of Fat}}{\text {Body Mass}} \times 100\)
This method was developed by the U.S. Navy's Naval Health Research Center (NHRC) in San Diego, California for estimating the body fat percentage. This method was developed specifically for military personnel to meet the requirements of body fat percentage for services.
Female:
Body Fat % = 163.205 × log10(Waist + Hips - Neck) - 97.684 × log10(Height) + 78.387
Male:
Body Fat % = 86.010 × log10(Waist - Neck) - 70.041 × log10(Height) + 36.76
Accuracy: 3.5%
Skinfold body fat measurements were introduced by researchers in 1978 named Dr. Andrew Jackson and M. L. Pollock. As with all of their methods, they aim to establish a system for assessing an individual's fat percentage. Both scholars incorporated to development of simple mathematical equations that take various body sites.
2.1 - Jackson Pollock 7:
In this test, men and women have the same measurements for body sites in mm (millimeters). These including:
For Female:
Body Density = 1.097 - (0.00046971 × sum of skinfolds) + (0.00000056 × sum of skinfolds2) - (0.00012828 × age)
\[ \text{Body Fat Percentage} = \frac{495}{\text{Body Density}} - 450 \]
For Male:
Body Density = 1.112 - (0.00043499 × Sum of Skinfolds) + (0.00000055 × (Sum of Skinfolds)2) - (0.00028826 × Age)
\[ \text{Body Fat Percentage} = \frac{495}{\text{Body Density}} - 450 \]
2.2 - Jackson Pollock 4
For both men and women, the skinfold measurements are taken from the same area of the body:
For Female:
Body Density = (0.29669 × Sum of Skinfolds) - (0.00043 × (Sum of Skinfolds)2) + (0.02963 × Age) + 1.4072
\[ \text{Body Fat Percentage} = \frac{495}{\text{Body Density}} - 450 \]
For Male:
Body Density = (0.29288 × Sum of Skinfolds) - (0.0005 × (Sum of Skinfolds)2) + (0.15845 × Age) - 5.76377
\[ \text{Body Fat Percentage} = \frac{495}{\text{Body Density}} - 450 \]
2.3 - Jackson Pollock 3
In 3-site body fat, males and females vary in body size measurements.
For Female:
Body Density = 1.0994921 - (0.0009929 × Sum of Skinfolds) + (0.0000023 × (Sum of Skinfolds)2) - (0.0001392 × Age)
\[ \text{Body Fat Percentage} = \frac{495}{\text{Body Density}} - 450 \]
For Male:
Body Density = 1.10938 - (0.0008267 × Sum of Skinfolds) + (0.0000016 × (Sum of Skinfolds)2) - (0.0002574 × Age)
\[ \text{Body Fat Percentage} = \frac{495}{\text{Body Density}} - 450 \]
2.4 - Durnin/Womersley
In Durnin & Womersley method, taking body fat at 4 sites:
For Female:
Body Density (D) = 1.1599 - (0.0717 × log(Sum of skinfolds))
\[ \text{Body Fat Percentage} = \frac{495}{\text{Body Density}} - 450 \]
For Male:
Body Density (D) = 1.1631 - (0.0632 × log(Sum of skinfolds))
\[ \text{Body Fat Percentage} = \frac{495}{\text{Body Density}} - 450 \]

Accuracy: For all skinfold methods the range in between 3.5 - 5%
For Male:
BFP = 1.20 × BMI + 0.23 × age − 16.2
For Female:
BFP = 1.20 × BMI + 0.23 × age − 5.4
For Boy:
BFP = 1.51 × BMI - 0.70 × Age - 2.2
For Girl:
BFP = 1.51 × BMI - 0.70 × Age + 1.4
Accuracy: 5% to 10% for the general population.

Having a very low body fat level can cause:
A specific amount of body fat is necessary for our health, known as essential fat. It is crucial for various things like organ function and hormone production. The exact amount may vary but typically it's considered 3% for men and 12 % for females.
