Factors that affect the accuracy and precision of this method include instrumentation, subject factors, technician skill, and the prediction equation formulated to estimate the fat-free mass. 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.

Different scales often give different numbers, and depending on the time of day you weigh yourself, your numbers may vary. Try weighing yourself on the same scale at approximately the same time of day over a few days to get an average of your body weight. You can easily calculate your BMI by dividing your weight in pounds by your height in inches squared, and then multiplying by a conversion factor of According to a study published in the British Journal of Nutrition in , if you are an adult, your percentage of body fat can be estimated as accurately as with skin-fold measurements and bioelectrical tests using the following gender-based formulas in conjunction with your BMI.

This calculation has been shown to slightly overestimate body fat percentage in people who are very overweight. Take your BMI result from Step 3 and plug it into the appropriate formula below to calculate your body fat percentage.

After learning how to calculate average body fat percentage, take a moment to compare the result you got in Step 4 to the body fat percentiles in Step 1. Comparing your results with these numbers should give you a good indication of how close or how far you may be from your ideal body fat percentage.

If your BMI or body fat percentage is higher than what you want it to be, a slight change in your lifestyle or workout routine can make a big difference, and having the right equipment enhances the effects to help you achieve the body you want.

It was hard but I humbled myself and listened; 2 years later I have nothing but respect and admiration for these guys.

Training has always been a way to focus my energy but after consulting with Steve and learning a fraction of his vast knowledge and putting this into practice I was able to take advantage of my training capability and understand how I could transform negative experiences in my life of illness and hardship into pushing further and making me stronger both mentally and physically.

With my change in body composition it also inspired me to learn Callisthenics a type of gymnastics. I had grown in confidence and learnt a lot from Steve and Mark. To me they are truly inspirational people. They may not see themselves as mentors but to me; how they have conduct themselves and how they have helped me, this is how I see them.

Steve was able to help me even with my personal dietary requirements and I have been able to build lean mass and continue to grow in strength. Steve helped me to understand how, even with my dietary restrictions that I could still surpass my wishes and excel in my training and well being.

It has inspired me to help others as Steve has also helped me realise my passion for training again and the way he has helped me achieve my goals, I also wish to help others. Training has helped me during work, relationships and as a person.

I am grateful because this would not be the case if Steve had not helped me to realise my potential in training and what I could achieve if I just focused. Meeting Steve was one of those tasks that I kept meaning to do and kept not getting around to it.

Finally I found myself face to face with Steve and talking our way through the challenges I was having. I needed I needed to lose weight to get fit enough to enjoy my active business life.

Steve humoured me and took notes, he listens well. I could tell he had heard this story many times before. Patiently he coaxes me on to the scales and talks to me about the challenges people have weighing themselves.

There is a part of me that feels like I have finally come face to face with the bank manager who wrote to me in my late teens — there is no avoiding it, a hard number is about to appear.

Now on to the body fat measurements, outcome the callipers and the calculations. Steve knows this is a challenge for people but handles it with grace and dignity and helps me to understand the numbers and charts. A clear picture of my nutritional health is starting to take shape.

We sit down and design a change in diet that is manageable. Over the course of the next several months we take on the other meals and start to work on a simple exercise plan.

Even though the changes were small to start off with, every month I lost a bit of weight and body fat. Things were working but not as fast as Steve thought they should be, we decide to carry out blood and stool tests to see how my body is digesting food and whether there were any food sensitivities.

Three weeks later we have the results, it turns out that I was having some reactions to foods that I was unaware of. We came up with a solution which meant certain foods where out, but Steve focused on the foods that I could eat rather than focusing on what I should not be eating.

Nothing changes for a couple of weeks and then finally the needle on the scales begins to flicker and start to come down. I start to lose weight, keep the exercise going, lose more weight, feel healthier and bingo I am finally on the path to good health.

Although I am now in Canada, I still plan on seeing Steve when I return to England on work. He is patient, polite and professional. He researches and questions and is always learning. Great customisable and workable service based on science and compassion. Totally recommend!

I have learnt a lot from Steve over the months! He has a straight to the point approach which I love! I would definitely recommend Steve to anyone looking for a nutritionist or a functional medicine practitioner!

I am so happy that Steve was recommended to me. My long standing digestive issues were impacting daily on my life and since meeting Steve I am feeling so much better both physically and mentally. I have seen many practitioners over the years and Steve is the only one who I have seen many practitioners over the years and Steve is the only one who has truly made a difference to my health and well being.

When experiencing a health issue, nothing that I tried worked and I knew I had to get help from an expert in this field. Luckily Steven was recommended to me by a close friend and after our initial consultation, my life changed for the better. He helped me to address and He helped me to address and reverse a health issue I was having an imbalance of yeast in the gut which was causing other issues such as water retention and weight gain.

I became the healthiest and happiest version of myself. Shortly after this I fell pregnant and had the healthiest and happiest of pregnancies I could have ever wished for. In addition, he took the time to reply to all of my annoying emails, and still does to this day.

I can highly recommend Steve for both your body composition and health related goals. Join our newsletter list for free weekly content, discounts and your FREE seasonal recipe eBook. What is an appropriate body fat percentage goal?

Total body fat can be split into two categories: essential fat and storage fat. Classifications of percentage body fat Whilst research clearly shows that increased body fat is associated with a host of chronic diseases and increased mortality, too low body fat is also associated with severe health risks and is dangerous.

American council of Exercise ACE ranges calliper-based measurements Whilst we have used skinfold callipers in clinical practice, we find the equations associated to calliper use do not provide an accurate measurement of body composition when compared to more gold standard measurements.

American College of Sports Medicine ACSM ranges These ranges are based upon a sample size of 18, individuals Males Females Proposal of normative table for body fat percentages through bioimpedanciometry — Journal of Exercise Rehabilitation Is there an ideal body fat percentage?

We can carry out these body composition assessments at our clinics in London and Hertfordshire. Health effects of too low body fat Too low body fat, and for a long period of time, may have a devastating effect on your health. Health effects of too high body fat Too low body fat, and for a long period of time, may have a devastating effect on your health.

How to work out what is your ideal body fat percentage? Consider feedback from your body to inform decisions: If you have any potential signs that your body fat is too low, begin taking action to change this or enlist some support.

Consider body weight and composition measurements: If you have had feedback from your doctor that you may be under or overweight, it might be worth further investigating this.

Consider what is right for you: Whilst average body fat percentages can be helpful information for one to be aware of, remember that you are unique and to ultimately follow what is right for you.

A few words on Body Mass Index BMI Whilst it is assumed that BMI is strongly positively associated with body fat percentage, studies indicate that this relationship may not be so strong Meeuwsen et al.

Key take-aways: Body fat is essential for health and well-being: having both too low body fat levels and too high body fat levels are associated with severe health complications. References Lee et al. Predicted lean body mass, fat mass, and all cause and cause specific mortality in men: prospective US cohort study.

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.

First, you must consider variables such as body type, heredity, age, activity and gender. For instance, the range for a healthy body fat percentage in women tends to be higher than that of men, as women need more body fat.

A certain amount of fat is important for bodily functions. So it's important to have neither too much nor too little body fat. If you'd like to try and reduce your body fat percentage, consider a new Yoga or Pilates class.

Mayo Clinic staff, as well as other health professionals, list the following age-adjusted body fat percentile recommendations:. Obtain as accurate a body weight as possible. Different scales often give different numbers, and depending on the time of day you weigh yourself, your numbers may vary.

After learning how to calculate average body fat percentage, take a moment to compare the result you got in Step 4 to the body fat percentiles in Step 1.

So if this sounds like you, too, relax. Ignore the BMI lies and take a different approach to determining your body-fat percentage than your less-fit friends. To add insult to injury, there are many reasons your scale or BMI are not even providing you with accurate results.

Mansour says these could include the following:. So can we all agree to ignore the BMI calculator when trying to accurately determine your body-fat percentage? Look at other factors in your life , including the following:.

And, as you know, muscle beats fat for many reasons. Instead, sports nutritionists and trainers urge active women to consider where their fat is stored. Abdominal fat, for example, is increasingly linked to metabolic syndrome and heart disease. Women whose waists are 35 inches or more have a higher risk of health problems than those with smaller waists, no matter how much they weigh.

The term athletic in this context refers to sports where low body fat is an advantage. Different sports have different requirements in terms of body composition. In some contact sports such as American football or rugby, a higher body weight is generally seen as an advantage.

In sports such as gymnastics, marathon running, and other weight-bearing activities, a lower body weight and high power-to-weight ratio are extremely important. Therefore, in these sports both low body fat and low body weight are necessary.

In sports such as body­building, increasing lean-body mass and increasing body weight without increasing body fat are desir­able. No accepted percentage body fat standards exist for athletes. The ideal body composition is highly dependent on the particular sport or discipline and should be discussed on an individual basis with the coach, physiologist, and nutritionist or dietician.

Body weight and body composition should be dis­cussed in relation to functional capacity and exercise performance. Learn more about Sport Nutrition, Second Edition. Previous Next. Call Us Hours Mon-Fri 7am - 5pm CST.

Anything below In his prime, Arnold Schwarzenegger had a whopping BMI of On the flip side, research shows that BMI also can be a false indicator of health in other ways. According to the American College of Cardiology , researchers presented their findings, which showed that individuals with a normal BMI can still have a high body-fat content, increasing their risk for cardiovascular disease and other health-related problems.

Because muscle is denser than fat, it takes up less space on your frame. As you advance in your training and gain more lean muscle mass, the spikes in your weight and BMI are signs of progress — not reasons to lose motivation.

It may sound high, but since I work out regularly, I have a lot of muscle on my body. Athletes, bodybuilders and those who strength-train regularly often have higher BMIs. So if this sounds like you, too, relax.
