BIA body fat percentage calculation -

All of these potential complications have the ability to reduce a person's life expectancy, and as such, obesity is a medical condition that is studied by many researchers.

As previously mentioned, fat produces a number of essential hormones that affect a person's body. An excess or a lack of critical hormones can have negative effects that preclude proper body function. On a related note, studies have found that excess body fat, particularly abdominal fat, disrupts the normal balance and function of some of these hormones.

Furthermore, body fat, specifically visceral fat, has a role in the release of specific cytokines, which are a broad category of proteins involved in cell signaling, that can potentially increase the risk of cardiovascular disease.

Visceral fat is also directly associated with higher levels of low-density lipoprotein LDL cholesterol, lower high-density lipoprotein HDL cholesterol, and insulin resistance.

LDL cholesterol is commonly referred to as "bad cholesterol" while HDL is referred to as "good cholesterol. Insulin resistance involves cells not properly responding to the hormone insulin, which can lead to high blood sugar levels, and eventually to type 2 diabetes.

As can be seen, excess visceral fat can have measurable negative impacts to a person's health. There are many specific techniques used for measuring body fat. The calculator above uses a method involving equations developed at the Naval Health Research Center by Hodgdon and Beckett in The method for measuring the relevant body parts as well as the specific equations used are provided below:.

Once these measurements are obtained, use the following formulas to calculate an estimate of body fat. Two equations are provided, one using the U.

customary system USC , which uses inches, and the other using the International System of Units, specifically the unit of centimeters:. Note that the results of these calculations are only an estimate since they are based on many different assumptions to make them as applicable to as many people as possible.

For more accurate measurements of body fat, the use of instruments such as bioelectric impedance analysis or hydrostatic density testing is necessary. Another method for calculating an estimate of body fat percentage uses BMI. These tools measure body fat using Bioelectric Impedance Analysis BIA.

A very low power current is passed through the body, and makes an assessment based on the level of water content in the body muscle holds a high water content while fat holds a low content.

As you become slimmer you may find calipers provide a more accurate result as it is easier to "pinch" the fat. This explains why body fat analyzers are better for more obese people, as the amount if internal fat will normally be higher and is not picked up by the fat calipers.

Simply dropping food intake and doing nothing else will usually result in a loss of fat as well as muscle. Women: Measure halfway between navel and sternum breastbone.

Abdomen mm Take the fold vertical about 1 inch to the side of the navel. Thigh mm Take fold half way between knee and hip. Suprailic mm Take a diagonal fold halfway between hip joint and bottom of rib cage. RESULTS Body Fat? Estimate method A quick estimate using weight, age, and waist size.

But these research studies generally do not test the scales you find in the store. Experts generally agree that the accuracy of the measurement depends, in part, on the quality of the device. In addition, other factors may affect a reading when you use a BIA scale. Some researchers also say that ethnicity can affect the accuracy of BIA measurements.

Overall, studies show that this method is not very accurate although it may be able to track change over time, your results are unlikely to reflect your actual body composition.

Even if you get an accurate reading on a bioimpedance scale, the number represents an estimate of your total body fat percentage. Bioelectrical impedance analysis does not accurately measure your total body fat.

Most scales also cannot tell you where fat is located on your body. Even though many factors can affect your reading accuracy, a regular BIA scale can show you changes in your body fat over time.

The actual number may not be perfect, but you can still track changes to your body composition. Because many BIA scales offer several features for a reasonable cost and are a quick and easy way to estimate body fat percent, body fat scales that use bioelectrical impedance analysis are a worthwhile investment for consumers who are curious about their body composition.

Keep in mind that they are not likely to be very accurate but you can use them to track changes over time. Using another method of tracking your body composition can help you get a better picture of your actual measurements.

It's also wise to understand that there is more to health than your body fat percentage or weight, and these scales are only a tool, not a reflection of your general wellness.

Cardiovascular exercises fat percentage is the percentage of your weight that is made up of fat. It consists of both storage body fat and essential body fat. There are several ways in calculating body fat percentage, including bioelectrical impedance analysis, skin-fold methods and other anthropometric methods, or methods involving the circumference of various body parts. Here's a method to calculate your body fat using only your scale and a calculator.
