Body fat measurement techniques -
HW was formerly the most trusted body composition testing method up until the Bod Pod came into play. Some people might feel uncomfortable exhaling all of the air from their lungs while underwater, although it is performed in shallow water.
The tank must be emptied and cleaned after each weighing, thus it takes longer to perform several tests in a day compared to a Bod Pod. The Bod Pod is an egg shaped device that measures body volume and body weight to determine body density and body fat.
First, you step on an electronic scale outside of the device which measures your weight. Then, you measure the air pressure of the Bod Pod without you in it. Next, step into the chamber and let the machine measure the air pressure with you in it.
These values will give you the volume of the empty Bod Pod and the volume of the pod with you inside. The software uses density to estimate body fat. We tried a Bod Pod and it only took a few minutes to complete two testing trials.
The results are printed immediately and you also get your resting metabolic rate RMR and total energy expenditure estimates TEE. Recent research, such as this European Clinical Journal of Nutrition study and this American Journal of Clinical Nutrition study shows that the Bod Pod is safe and accurate for body composition analysis.
There are certain things you must do in order for the rest to work properly. There you lose some accuracy. In a DEXA scan, you lie down and receive a scan of your body composition and bone mineral density.
DEXA systems use a source that generates x-rays at two energies to estimate bone mineral content and soft tissue composition. Also, with DEXA, you find out exactly where your fat is located; it can actually tell you the amount of belly fat you have.
Finding a place that offers DEXA scans for body composition might take some digging. Skin calipers are the most accessible method in determining body fat percentage. A technician uses the device by pinching a layer of skin to get any underlying fat.
Sites that are measured are: triceps, pectoral, abdominal, supriliac, and thigh. There are two steps to determining body fat percentage: body density and using body density to estimate body fat.
The body density equation was developed for each by Dr. Andrew Jackson and M. As for the fat percentage equation was created by Siri and Brozek As mentioned before, skin calipers are easily accessible, making them a huge pro. Too much of this fat can lead to metabolic syndrome. Skin calipers require a lot of accuracy, and usually the technician has to go through rigorous training to be certifiable to use one.
This can lead to false results, adding more fat to a lean, ripped physique. Body fat scales are also called bioeletrical imedance scales, which is quite similar to a normal scale. The only difference is that there are electrodes under your feet or where you places your hands on the hand-held device.
A small electrical impulse gets sent through the body, and the rate of the impulses are measured. Lean tissues conducts electrical impulses quicker than fat. The scales are affordable and most gyms have the hand-held device. Both devices only require you pressing a button, making it user-friendly.
Accuracy is the biggest down fall of this method because readings can be impacted by hydration levels, meal times, and workouts. Another method is waist-to-hip ratio, which gets determined by the use of a measuring tape.
Using the measuring tape, measure the circumference around the widest part of your buttocks and then around your waist. Once you get both measurements, divide your waist measurement by your hip measurement. Each method requires a simple calculation. Accuracy is another issue for the two methods.
Hence, muscle weighs more than fat—giving an inaccurate measurement. Body fat testing is a great way to have an accurate metric for your body composition. There are many ways of getting your body fat tested, but most experts will agree that the DEXA Dual-Energy X-ray Absorptiometry scan is the most accurate testing technology available.
Think X-rays were just for broken bones? A DEXA scan exposes patients to X-ray beams of differing intensities and can be used to measure bone mineral density alongside body composition. Participants lie still on a table while a machine arm passes over their entire body, which emits a high- and a low-energy X-ray beam.
By measuring the absorption of each beam into parts of the body, technicians can get readings for bone mineral density, lean body mass and fat mass. And since the machine scans body parts individually, the test can also break down body composition per limb so you can confirm your suspicions that your right leg is indeed just a bit stronger than your left.
DEXA scans are incredibly accurate at measuring body composition. A DEXA scan is quick, dry and painless, involving simply lying on a table for a few minutes. DEXA has surpassed hydrostatic weighing as the gold standard and is being utilized as the criterion measure in clinical research more so than underwater weighing hydrostatic.
Getting a DEXA scan usually involves making an appointment with a medical professional. The high level of accuracy also comes at a relatively high price tag compared to other methods, which will vary based on location. Air-displacement plethysmography is actually very similar to underwater weighing.
First, participants sit in a small machine; then, by measuring how much air is displaced by the individual, technicians can determine body density.
The shape and size of the machine used in this technique, which typically resembles an egg, makes it accommodating for persons of almost any age, shape and size. While commercial machines might pop up at select high-level training facilities, locating one near you might be difficult.
Regardless of which method you choose, you should wait at least six to eight weeks before re-measuring body fat percentage and use the same method.
Find a method that works for you and stick with it. Though bioelectrical impedance and skin calipers tend to be slightly less accurate than more high-tech methods like underwater weighing, they can still be an incredibly useful tool if you just want to track your loss fat and gains muscle.
And remember, body composition should be just one metric on the road to health and fitness alongside others like sleep quality, energy levels and happiness — not the entire focus of your training.
Most people are rarely excited with their baseline body fat test. Keep in mind that your body fat percentage should be viewed as a metric in the same way that your total cholesterol or liver enzyme values are metrics of your health.
This is where you start to take a look at things such as — lifestyle, diet, supplements, medications, aging, and other factors can begin to affect your health.
Most people a body composition goal, it can also be useful to have this data point tested again to validate whatever training and nutrition strategy you may be using. That being said, most people want to know more about where they stand and there are various sources for helping you interpret body fat percentages.
One of the most commonly referenced charts is from the American Council on Exercise. Another useful chart is sourced from the research of Dr. Andrew Jackson and M. We at Invictus prefer this chart over the ACE chart as it accounts for both gender differences AND age differences.
Simply find your age category in the left hand column of your respective gender, and then look across to see where you fall in your age group.
Body fat testing provides another very important number: lean body mass LBM. Your LBM is simply your body fat subtracted from your total body weight. LBM includes organs, bones, muscle, and everything else in your body besides body fat.
Typically, changes in LBM are primarily from increases or decreases in muscle mass. Changes in bone density can affect your LBM as well, however a DEXA scan will be able to differentiate between the two.
Usually, this is listed as Bone Mineral Content BMC on a DEXA report. A hydrostatic test will give you LBM and body fat only. If your goal is to get leaner, you need to decrease your body fat percentage while maintaining or increasing your LBM. Your LBM is also very useful for helping us calculate your daily nutritional requirements.
Well, common sense tells us a pound of muscle and a pound of fat have to weigh the same; however, they do differ when it comes to density. This means if you look at five pounds of muscle and five pounds of fat side by side on a table, the fat will take up more volume, or space, than the muscle.
The same holds true with your body; you may look noticeably leaner due to fat loss, but when you add in muscle gain, the weight on the scale could be up five or maybe even ten pounds more than it was before. If you look and feel leaner but your weight is up on the scale, then a body fat percentage testing method may be a better choice for those who like to set milestone numbers for body composition goals.
Ask yourselves — at the end of the day, which is more important: how you look, feel and perform, or what the cold hearted scale tells you whenever you step on it? There was a time when I wrote down and recorded every single thing that I ate and drank; I also would weigh myself times a day.
I did both of these things every single day for months at a time; and when I decided I needed a mental break from all of that dedication, I found it to be actually quite hard for me to stop, as weighing myself became a habit — an obsession — that was very hard to break. For those of you who weigh themselves on a regular basis, I challenge you to hide your scale away and not weigh yourself for seven days.
Stick to one source. Yes, this reason needs just one word to sum it up. Hormones play a big role in wreaking havoc on the scale for women, even causing their weight to fluctuate from day to day, depending on your time of the month.
You may not feel bloated, but you could be retaining fluids. Studies have shown that women hit a peak day of fluid retention at the start of their menstrual cycle, with some women retaining fluids the days leading up the cycle [1].
We all want to be healthy, look great and perform our best in life, both inside and outside of the gym. Obsessing about the weight on a scale can actually get in the way of your body composition goals.
This is an informative and insightful post about the significance of body fat testing and the crucial role of lean body mass LBM in understanding overall health and fitness. For those aiming to achieve a leaner physique, the emphasis on reducing body fat percentage while preserving or increasing LBM is crucial and also students can dig this to have quality work.
This approach ensures that any weight loss primarily comes from fat loss, rather than muscle loss, which is essential for maintaining metabolic health and overall strength.

I would caution women of childbearing age to have the test done at the same time each month, as inconsistency may alter accuracy. Pregnant women and those with implantable pacemakers or defibrillators should avoid BIA.
This method is made possible because a relationship exists between subcutaneous fat and the total amount of body fat. While this method can yield good results when done properly, it has several drawbacks.
For example, this method does not measure visceral fat. Also, different people pinch differently, which can alter accuracy. Having the same person do the test may minimize this error. Big-chain health clubs often do not use this method because people may feel uncomfortable being touched by strangers, and touching perceived as inappropriate can lead to lawsuits.
The NIR machine then uses this information along with age and activity level to estimate body composition. While variations of this technique have been used in clinical settings since the s, portable devices that are commercially available have been shown to be less accurate than other methods.

Equations are used to predict body fat percentage based on these measurements. BIA equipment sends a small, imperceptible, safe electric current through the body, measuring the resistance. The current faces more resistance passing through body fat than it does passing through lean body mass and water. Equations are used to estimate body fat percentage and fat-free mass. Individuals are weighed in air and while submerged in a tank. Fat is more buoyant less dense than water, so someone with high body fat will have a lower body density than someone with low body fat. This method is typically only used in a research setting. This method uses a similar principle to underwater weighing but can be done in the air instead of in water. Individuals drink isotope-labeled water and give body fluid samples. Researchers analyze these samples for isotope levels, which are then used to calculate total body water, fat-free body mass, and in turn, body fat mass. X-ray beams pass through different body tissues at different rates. So DEXA uses two low-level X-ray beams to develop estimates of fat-free mass, fat mass, and bone mineral density. These two imaging techniques are now considered to be the most accurate methods for measuring tissue, organ, and whole-body fat mass as well as lean muscle mass and bone mass. Measurements of Adiposity and Body Composition. In: Hu F, ed. If the thought of getting dunked underwater suits your fancy, this might be the method for you. This number is then used to estimate body composition. Hydrostatic weighing is an incredibly accurate technique for measuring body composition. The technique uses tried and true variables that feature a low percentage of error. For that reason, many experts refer to hydrostatic weighing as the gold standard for measuring body composition. As a result, this method can be a bit inconvenient. Subjects also have to forcefully exhale as much air out of their lungs as possible to reduce potential for error and sit submerged completely underwater. This might be uncomfortable for some individuals. Think X-rays only detect broken bones? A DEXA scan exposes patients to X-ray beams of differing intensities. And experts use it to calculate bone mineral density alongside body composition. Participants lie still on a table while a machine arm passes over their entire body.

Styku is another body mapping machine, offering similar readings. For most body types, 3D mapping comes within two percent of the accuracy of the DEXA method. You do, however, need to worry about your clothes. But if you prefer, tight pants and a top also works. Just remember to wear that same outfit for every reading. Standing as still as possible during the scan is also how to ensure the most accurate results. Regardless of which metric you go with, resist the urge to test on a weekly basis. According to Kneeland, results take time. Though bioelectrical impedance and skin calipers tend to be slightly less accurate than more high-tech methods like underwater weighing, they can still be an incredibly useful tool.

Measuring your waist circumference can give you an idea of your body fat levels and whether or not you have a high amount of body fat stored around your midsection Carrying high amounts of fat in your midsection can significantly increase your risk of developing a number of health conditions, including heart disease, diabetes, and more Knowing your waist circumference can help you determine if you have too much fat stored around your midsection.
All you need to do is to place a non-stretch tape measure around your midsection above your hip bones, making sure the tape measure is horizontal around your waist. Keep the tape measure snug, but make sure to avoid compressing the skin In order to reduce the risk of many health conditions, health organizations recommend that waist circumference be kept below a certain measurement For example, those of Asian descent have lower waist circumference cut off values compared to those of European descent Waist circumference measurement is an easy way to assess body fat levels in your midsection.
However, these methods are typically much less reliable compared to methods used in clinical settings like DEXA. If you have questions about your body composition, including healthy body fat levels for your age, sex, and ethnicity, reach out to a trusted healthcare professional for advice.
