Within the matrix of body fat, also called Bod tissue, there is not only fat cells but nerve and immune cells and connective tissue. Macrophages, neutrophils, and eosinophils are some of the immune cells found in fat tissue that play a role in inflammation—both anti-inflammatory and proinflammatory. Fat cells also secrete percenntage and build enzymes involved with immune function and the creation of steroid hormones. Fat cells can grow in size and number.

Body fat percentage -

The measurements that need to be taken are slightly different for men and women. Men only measure waist circumference, but women also measure other parts of the body, including hips, wrist, and forearm.

Once you've gathered your numbers, input the data to calculate your body fat percentage. Now that you've got your number, you probably want to know how your body fat percent compares to other men or women in various categories.

According to the American Council on Exercise ACE , there are five different ranges or body fat categories. Keep in mind that these categories are based on body fat norms and may not be an indicator of your specific level of fitness or health.

It is problematic to assign a strict cut-off for what body fat percentage puts someone at higher risk of health concerns like heart disease, diabetes, and stroke.

Body fat percentage as a standalone figure does not account for sex, ethnicity, or age differences. There are other measurements that might help you evaluate your risk for conditions like cardiovascular disease.

If your body fat is too high according to the calculator, speak to a healthcare provider about different tools that you can use to measure your health risks. One of the most popular assessment tools is body mass index BMI.

BMI is a number that is used to evaluate your body size. It is not a percentage of body fat but a general score that helps determine if your weight falls into a healthy range. The number is calculated using your weight and height. If you carry too much weight for your height, the excess weight is assumed to be fat.

Body mass index is simply a tool that puts you into a category based on weight. It is not designed to be an accurate diagnostic tool for determining health. Despite being a flawed measure , BMI is widely used today in the medical community because it is an inexpensive and quick method for analyzing potential health status and outcomes.

Why does body fat percentage matter? If your goal is weight loss , you might be tempted to use a simple bodyweight scale for feedback on your progress, but your body fat percentage will tell you more than the scale.

When you are participating in intentional weight loss, boosting your health, or increasing your fitness level, fat loss should be your goal, rather than simple weight loss.

You want to keep the lean mass, or fat-free mass, that your body needs. Lean mass includes bone, blood, connective tissue, organs, and muscle. Muscle loss sometimes occurs when you lose weight, but it's not the kind of weight loss you seek. You want to maintain muscle mass because it helps your body to function and perform more efficiently, boosts your metabolism, and can help improve glycemic control.

By measuring changes in body fat percentage, you can tell how well your fitness or weight loss program is helping you to lose fat while maintaining fat-free mass.

There are many different ways to measure body composition or the amount of fat and lean mass on your body. Using a body fat calculator is just one of them. One method won't be appropriate for every body. For example, if you would be uncomfortable going underwater, you would not want to attempt hydrostatic weighing.

Each method also has its pros and cons. When you input body measurements into a body fat calculator like the one above, the tool uses a specific formula to estimate your percentage of fat. The formula is slightly different for men and women.

For women, the formula begins with a simple weight calculation:. The tool uses fractions of each body measurement to estimate your body fat percentage. For men, the formula begins with a different weight calculation:. The tool uses a fraction of the weight measurement to estimate your body fat percentage.

A body fat calculator is not the most accurate measurement of body fat percentage. However, it's the most accessible system to use. Therefore, you may be able to use it more often.

If you measure at the same time each day and use the same tools the same tape measure and the same online calculator , you can track trends in your progress, which can be far more valuable in assessing your fitness gains than a standalone measurement.

Several body fat calculators use skinfold measurements instead of body circumference measurements to estimate your body fat percentage. Skinfold calipers can be purchased to use at home, or you can hire a professional who is skilled in using them in healthcare or gym settings.

Skin calipers pinch a portion of your body to estimate fat levels. The caliper method can be more accurate than a calculator for measuring body fat percentage, but the accuracy depends on the skill level of the person using them.

Home scales, gym-quality scales, and devices in your healthcare provider's office may use bioelectrical impedance to estimate body fat. Simply put, the device sends a harmless, completely pain-free electrical signal through your body to measure fat. You get a quick and instantaneous body fat percentage result.

While this method is convenient, certain factors such as hydration level can influence the accuracy of the result. Whole-body scanning is quickly becoming the gold standard for measuring body fat percentage.

However, the main reason the test is so accurate is that it is generally performed in a medical setting by highly skilled technicians. The DeXA test is often costly and may not be available where you live.

Each bare foot may be placed on an electrode, with the current sent up one leg, across the abdomen and down the other leg.

For convenience, an instrument which must be stepped on will also measure weight. Alternatively, an electrode may be held in each hand; calculation of fat percentage uses the weight, so that must be measured with scales and entered by the user.

The two methods may give different percentages, without being inconsistent, as they measure fat in different parts of the body. More sophisticated instruments for domestic use are available with electrodes for both feet and hands.

There is little scope for technician error as such, but factors such as eating, drinking and exercising must be controlled [16] since hydration level is an important source of error in determining the flow of the electric current to estimate body fat.

The instructions for use of instruments typically recommended not making measurements soon after drinking or eating or exercising, or when dehydrated. Instruments require details such as sex and age to be entered, and use formulae taking these into account; for example, men and women store fat differently around the abdomen and thigh region.

Different BIA analysers may vary. Population-specific equations are available for some instruments, which are only reliable for specific ethnic groups, populations, and conditions. Population-specific equations may not be appropriate for individuals outside of specific groups. There exist various anthropometric methods for estimating body fat.

The term anthropometric refers to measurements made of various parameters of the human body, such as circumferences of various body parts or thicknesses of skinfolds.

Most of these methods are based on a statistical model. Some measurements are selected, and are applied to a population sample.

For each individual in the sample, the method's measurements are recorded, and that individual's body density is also recorded, being determined by, for instance, under-water weighing, in combination with a multi-compartment body density model.

From this data, a formula relating the body measurements to density is developed. Because most anthropometric formulas such as the Durnin-Womersley skinfold method, [18] the Jackson-Pollock skinfold method, and the US Navy circumference method, actually estimate body density, not body fat percentage, the body fat percentage is obtained by applying a second formula, such as the Siri or Brozek described in the above section on density.

Consequently, the body fat percentage calculated from skin folds or other anthropometric methods carries the cumulative error from the application of two separate statistical models.

These methods are therefore inferior to a direct measurement of body density and the application of just one formula to estimate body fat percentage. One way to regard these methods is that they trade accuracy for convenience, since it is much more convenient to take a few body measurements than to submerge individuals in water.

The chief problem with all statistically derived formulas is that in order to be widely applicable, they must be based on a broad sample of individuals. Yet, that breadth makes them inherently inaccurate. The ideal statistical estimation method for an individual is based on a sample of similar individuals.

For instance, a skinfold based body density formula developed from a sample of male collegiate rowers is likely to be much more accurate for estimating the body density of a male collegiate rower than a method developed using a sample of the general population, because the sample is narrowed down by age, sex, physical fitness level, type of sport, and lifestyle factors.

On the other hand, such a formula is unsuitable for general use. The skinfold estimation methods are based on a skinfold test , also known as a pinch test , whereby a pinch of skin is precisely measured by calipers , also known as a plicometer , [19] at several standardized points on the body to determine the subcutaneous fat layer thickness.

Some formulas require as few as three measurements, others as many as seven. The accuracy of these estimates is more dependent on a person's unique body fat distribution than on the number of sites measured.

As well, it is of utmost importance to test in a precise location with a fixed pressure. Although it may not give an accurate reading of real body fat percentage, it is a reliable measure of body composition change over a period of time, provided the test is carried out by the same person with the same technique.

Skinfold-based body fat estimation is sensitive to the type of caliper used, and technique. This method also only measures one type of fat: subcutaneous adipose tissue fat under the skin. Two individuals might have nearly identical measurements at all of the skin fold sites, yet differ greatly in their body fat levels due to differences in other body fat deposits such as visceral adipose tissue: fat in the abdominal cavity.

Some models partially address this problem by including age as a variable in the statistics and the resulting formula. Older individuals are found to have a lower body density for the same skinfold measurements , which is assumed to signify a higher body fat percentage. However, older, highly athletic individuals might not fit this assumption, causing the formulas to underestimate their body density.

Ultrasound is used extensively to measure tissue structure and has proven to be an accurate technique to measure subcutaneous fat thickness. By making thickness measurements at multiple sites on the body you can calculate the estimated body fat percentage.

Ultrasound equipment is expensive, and not cost-effective solely for body fat measurement, but where equipment is available, as in hospitals, the extra cost for the capability to measure body fat is minimal. There also exist formulas for estimating body fat percentage from an individual's weight and girth measurements.

For example, the U. Navy circumference method compares abdomen or waist and hips measurements to neck measurement and height and other sites claim to estimate one's body fat percentage by a conversion from the body mass index.

In the U. Navy, the method is known as the "rope and choke. The U. Army and U. Marine Corps also rely on the height and circumference method.

Females are measured around the hips, waist, and neck. These measurements are then looked up in published tables, with the individual's height as an additional parameter. This method is used because it is a cheap and convenient way to implement a body fat test throughout an entire service.

Methods using circumference have little acceptance outside the Department of Defense due to their negative reputation in comparison to other methods.

The method's accuracy becomes an issue when comparing people with different body compositions, those with larger necks artificially generate lower body fat percentage calculations than those with smaller necks. Body fat can be estimated from body mass index BMI , a person's mass in kilograms divided by the square of the height in meters; if weight is measured in pounds and height in inches, the result can be converted to BMI by multiplying by These formulae are based on work by researchers published in peer-reviewed journals, but their correlation with body fat are only estimates; body fat cannot be deduced accurately from BMI.

Body fat may be estimated from the body mass index by formulae derived by Deurenberg and co-workers. Internal and external cross-validation of the prediction formulas showed that they gave valid estimates of body fat in males and females at all ages.

However — contrary to the aforementioned internal and external cross-validation —, these formulae definitely proved unusable at least for adults and are presented here illustratively only.

Still, the following formula designed for adults proved to be much more accurate at least for adults: [28]. Other indices may be used; the body adiposity index was said by its developers to give a direct estimate of body fat percentage, but statistical studies found this not to be so.
