More Than A Fat Measurement Tool BIA is much more than a superficial tool to measure fat. How Does Bioelectrical Impedance Analysis Work?

What Measurements Does Bioelectrical Impedance Analysis Provide? A BIA measures several key objective markers of health also known as biomarkers , including: Phase angle : An indicator of cellular health independent of weight.

Phase angle values vary depending on your age and gender. Resistance : Resistance is the effect on an electrical current caused by different components in your body. A high resistance value indicates low amounts of fat-free body mass. A low resistance is consistent with high amounts of fat-free body mass.

A high value means healthy cells. This includes bone and muscle tissue. BCM includes the water inside living cells.

Intracellular water ICW : The water volume of the body cell mass. Increases in intracellular water can indicate better health. Extracellular water ECW : The volume of water outside of the body cell mass.

High levels of extracellular water can mean inflammation, infection, or mineral imbalance. Fat mass : The amount of fat in your body.

Extracellular mass ECM : ECM consists of all the metabolically inactive parts of your body, which includes your bone and blood plasma. It also includes the water outside living cells. Lean body mass LBM : Your total body weight minus your fat mass. How Can You Prepare for a Bioelectrical Impedance Analysis?

There are just a few guidelines to follow before your test: The day before your BIA : Ensure normal hydration by drinking 8 ounces of water every 2 hours. Do not engage in intense exercise or any lifestyle practices that can promote dehydration.

Avoid alcohol for 24 hours prior to the test. whereas others are trying to increase muscle mass. Each method is based on assumptions regarding the proportions and properties of fat mass and FFM. However, universities and medical facilities offer more sophisticated methods, such as Dual-Energy X-Ray Absorptiometry DEXA and Air Displacement Plethysmography Bod Pod.

The only direct method of measuring body composition is cadaver dissection, i. Each assessment method has a degree of variability, which is largely dependent on: the equipment, tester, and environmental conditions.

If these variables are controlled carefully, then the variability of the measurement is reduced. Most body fat methods are based on a two-compartment model, where the body is divided into two compartments: fat and FFM. Clients who want to increase muscle mass for performance or aesthetic reasons often focus on increasing FFM.

For example, a change in hydration affects total body water, which is included within FFM. This consideration is particularly important when using bioelectrical impedance analysis.

Various commercially available weighing scales can estimate body fat using a principle called bioelectrical impedance analysis BIA.

BIA is based on how an electrical current is conducted through different body tissues. The current flows more easily through areas of the body that are composed mostly of water such as muscle than it does through fat.

This variability is usually caused by changes in hydration status, body temperature or taking a reading at a different time of day. For example, if a person is dehydrated, the amount of fat will likely be overestimated. We demonstrate this effect during a practical class, which involves measuring the body composition of a student using BIA.

After the initial measurement the student drinks pints of water and the measurement is repeated after 30 minutes. If only losing body fat was this easy!

Skinfold calipers are used to measure subcutaneous body fat fat under the skin. Using various equations , the skinfold data can be used to calculate body density and body fat percentage.

As with all body composition methods, the skinfold technique involves a series of assumptions, such as adipose tissue compresses in a predictable manner and the thickness of skin is negligible.

We typically use the skinfold method when working with athletes, as the method offers good repeatability and we can perform this when travelling. Furthermore, this method allows us to perform segmental analysis. Fat-free mass contains mostly water, while fat contains very little water.

Thus, fat-free mass will have less resistance to an electrical current. By determining the resistance of a current running through your body, theoretically we could get an estimate of how much fat-free and fat mass you have. There are many BIA devices out there, including devices by Omron and Tanita.

While the theory behind BIA sounds nice, it is problematic. First, an electrical current will follow the path of least resistance through your body.

This means that, if you carry a large amount of fat underneath your skin, the BIA won't even hit it; the current will instead pass through internal tissues.

Second, I mentioned last week how hydrostatic weighing can be affected by the hydration of fat-free mass ; BIA is going to be even more affected by this.

And while there is one device that tries to differentiate between fluid inside your cells and outside your cells by sending the current at different frequencies , you still have the problem of the current following the path of least resistance.

Third, many BIA devices will miss entire sections of your body. For example, some devices, like Tanita scales, send the current through one leg and out the other, which means your entire torso is missed.

Some hand-held devices will send the current through one arm and out the other, missing the rest of your body. And while there is now one device that is able to send the current through every section of your body , it is still limited by all of the other problems associated with BIA.

The biggest problem with BIA is that it's a prediction based off of a prediction. When a manufacturer develops a BIA device, the manufacturer gathers a large group of people and determines their body composition using another method.

Usually, this method is not the gold standard of the 4-compartment model; most often it is hydrostatic weighing. The manufacturer then takes the results of the BIA equipment, and develops a prediction equation from those results and variables like the individual's height, weight, and gender.

This equation is designed to predict what your body fat would be if we were to perform underwater weighing on you, based on the BIA results. The problem here is that you have error compounding upon error.

Well, now we're trying to predict your hydrostatic-weighing-derived body fat using BIA. And this prediction itself is going to have an error. So we're multiplying the error by making predictions off of predictions. So how much error are we talking about here?

A lot. Here's a chart from one study , showing the difference between fat mass assessed by BIA versus a 4-compartment model:. The X-axis shows the difference in fat mass in kilograms between BIA and the 4-compartment model. The Y-axis shows the number of people who showed this difference this study involved 50 people overall.

To convert kilograms to pounds, multiply the number of kilograms by 2. First, you can see the chart is skewed to the right of 0.

This means that the 4-compartment model showed higher amounts of body fat than BIA for most people. Second, you can see some pretty large differences for quite a few people. In fact, in 20 out of the 50 people, BIA showed the people had at least 8 pounds less body fat than they really had.

Twelve out of the 50 people showed differences of more than 10 pounds. Here's another chart from a study on bodybuilders :. I just want you to focus on BIA. You can see that BIA had the biggest spread of all of the techniques. I've heard people make the argument that, while BIA may not be that accurate, it should work fine when tracking change over time.

The theory, they say, is that the error should be the same each time you use it. The problem is that this isn't true. As I mentioned in the article on hydrostatic weighing , the density and hydration of fat-free mass can change with weight loss. If this can affect the accuracy of hydrostatic weighing for measuring change over time, then you can be sure that the effect on BIA outcomes is going to be significantly larger.

Researchers have looked at the accuracy of BIA for tracking body fat change over time. In one study , the disagreement between BIA and the 4-compartment model ranged from This means you could lose 3. Or, BIA could tell you that you lost 8. In fact, in this study, plain ol' bod mass index BMI did just as well as BIA for predicting change in body fat, except for in one person.

Let's take a look at that study on bodybuilders I mentioned earlier. The error gets even larger:. Again, you can see BIA had the biggest spread of all the methods, even bigger than BMI.

Bioelectrical impedance analysis BIA measures body composition based on the rate at which an electrical current travels through the body. Body fat adipose tissue causes greater resistance impedance than lean mass and slows the rate at which the current travels. BIA scales estimate body fat percentage using bioelectrical impedance analysis.

While it can be tempting to rely solely on the scale to gauge your success, understanding and monitoring your body composition can provide a much more comprehensive and nuanced view of your overall health and weight loss achievements.

At Austin Luxury Medspa, we believe that empowering our clients with knowledge is essential for achieving sustainable weight loss outcomes.

To that end, we offer comprehensive education and support in understanding the importance of body composition and the most effective methods for monitoring your progress. For example, gaining muscle while losing body fat is a positive change, even if your overall weight remains the same.

Body fat percentage is a valuable metric for assessing weight loss progress, as it represents the portion of your total body weight composed of fat.

Your body fat percentage can help professionals determine an appropriate weight loss strategy and set realistic goals. Lean body mass encompasses muscle mass, bone mass, and internal organs, excluding body fat. Monitoring changes in lean body mass can provide insights into the effectiveness of your diet and exercise regimen and help identify areas for improvement.

BIA is a non-invasive, quick, and cost-effective method for estimating body composition. Since fat and muscle tissues have different levels of resistance, BIA can provide an estimate of your body fat percentage and lean body mass. Some modern scales and handheld devices utilize BIA technology for at-home body composition monitoring.

DXA is a highly accurate method of analyzing body composition, involving the use of low-level X-rays to distinguish between bone mass, fat mass, and lean mass. While DXA scans are generally more expensive and less accessible than other methods, they offer superior accuracy and can be a valuable tool for individuals seeking precise body composition measurements.

Skinfold measurements involve using calipers to measure the thickness of skin and subcutaneous fat at specific locations on your body. A trained professional can use these measurements to estimate your total body fat percentage.

While not as accurate as DXA scans, skinfold measurements are more cost-effective and widely accessible. The Bod Pod is a device that uses air displacement to determine body composition by measuring the volume of air your body displaces while you sit inside a small chamber.

Or, BIA could tell you that you lost 8. In fact, in this study, plain ol' bod mass index BMI did just as well as BIA for predicting change in body fat, except for in one person.

Let's take a look at that study on bodybuilders I mentioned earlier. The error gets even larger:. Again, you can see BIA had the biggest spread of all the methods, even bigger than BMI. Here's a chart from a study that I mentioned earlier:.

Chart showing difference in fat loss kilograms between BIA and a 4-compartment model. The x-axis shows the difference, and the y-axis shows the number of people with that difference.

The x-axis shows the difference in fat loss in kilograms between BIA and a 4-compartment model. The y-axis shows the number of people with that difference.

The chart is heavily skewed to the left, meaning most of the people lost more body fat than what BIA indicated. Twelve out of the 50 people lost over 5 more pounds of fat than indicated by BIA, and a few people lost around 15 more pounds of fat than indicated by BIA.

The fact that BIA underpredicts fat loss in most people is not surprising. As I mentioned earlier, the electrical current of BIA won't even pass through fat underneath your skin, so you could lose a lot of fat and BIA won't detect it. In fact, the only reason BIA will even show a loss of fat is because you lost weight, and weight is a component of BIA prediction equations.

This is why BIA doesn't do much better than BMI in some studies. My own clinical experience with BIA verifies this. In the clinic for which I used to work, we had large weight losses.

Our clients were losing nearly 40 pounds on average, and we had people in the program at any one time point. It did not happen very often, but it did happen. When it did happen, it was psychologically devastating to the client; we sometimes would have a client cry over it. We would try to explain to the client that the BIA can be highly inaccurate, but the client would hang onto the number rather than looking at weight and circumference measurements which told the real story.

Most of these clients were Microsoft employees, so they tended to be very "hard numbers"-oriented individualls. I actually campaigned to do away with BIA completely, but Microsoft whose insurance covered our program required us to measure body composition.

So one change we did make was to drastically reduce the frequency of BIA measurements, taking a measurement only before and after the program, rather than every 5 weeks which is what had been done before.

This helped reduce the problem, but did not completely eliminate it. BIA can be problematic because it's a prediction based off of a prediction, so the error gets compounded. When you look at group averages for BIA measurements, there tends to be bias, with BIA often underpredicting how much fat you have.

In fact, BIA doesn't do much better than BMI at predicting body fat in some cases. For all of these reasons, I am not a fan of BIA for measuring body composition in individuals. If you are going to use BIA for tracking body composition over time, I recommend very long time intervals between measurements at least 3 months, but 6 months is probably better , as the error rate for BIA can be larger than the changes in body fat in you see.

I always laugh because most all of the bariatricians I know use a handheld BIA like the one shown. I am familiar with multifrequency, multicompartment BIA equipment like the ones you link to. However, it will still have many of the other limitations that BIA has. So, while better than older pieces of BIA equipment, there will still be sizeable error rates on an individual level.

I just read through your piece on BIA testing and just thought I would put forth my experience. We do it every months as a goal and we use the RJL Quantum II. This may include avoiding exercise for 4 hours prior to the test, avoiding a meal for hours prior to the test water is ok , avoiding saunas, and abstaining from alcohol for 12 hours prior to the test.

Make sure to ask the clinician who performs your test about the pre-testing requirements. Bioelectrical impedance analysis BIA is a quick and painless way to get a read on your body composition. It's accuracy is on-par with other practical body composition techniques.

If you have the chance to have this test done, I would recommend it! For more information on body fat: Factors That Affect Body Fat Understanding Body Composition and Testing for It.
