Electrical currents move through muscle easier than fat due to the higher water content of muscle BIA devices work by sending small electrical currents through your body to see how easily they travel through your tissues. Many different devices are available, although advanced devices produce more accurate results.

BIS and BIA devices look similar but use different technology. BIS uses a much larger number of electrical currents than BIA, in addition to high and low frequencies, to mathematically predict your amount of body fluid BIS also analyzes the information differently, and some researchers believe that BIS is more accurate than BIA 14 , However, similar to BIA, BIS uses the body fluid information it gathers to predict your body composition based on equations The accuracy of both of these methods depends on how similar you are to the people for whom these equations were developed However, BIS uses more electrical currents and processes the information differently.

However, while BIA and BIS send currents through your whole body, EIM sends currents through smaller regions of your body These devices are placed on different parts of the body to estimate the body fat of those specific areas Because this device is placed directly on specific body regions, it has some similarities to skinfold calipers, although the technologies are very different.

EIM injects electrical currents into small body regions. Portable devices are placed directly on different body parts to estimate the body fat percentage at those locations. More research is needed to establish the accuracy of this method.

For some devices, you stand on a rotating platform for several minutes while the sensors detect your body shape. Other devices use sensors that rotate around your body.

In this way, 3-D body scanners are similar to circumference measurements. However, a greater amount of information is provided by a 3-D scanner The method uses information about your body shape to predict your body fat percentage.

More information is needed about the accuracy of these methods. Multi-compartment models are considered to be the most accurate method of body composition assessment 3 , These models split the body into three or more parts.

The most common assessments are called 3-compartment and 4-compartment models. These models require multiple tests to get estimates of body mass, body volume, body water and bone content For example, hydrostatic weighing or ADP can provide body volume, BIS or BIA can provide body water and DXA can measure bone content.

Information from each of these methods is combined to build a more complete picture of the body and obtain the most accurate body fat percentage 21 , However, they involve multiple tests and are not typically available to the general public.

Some methods, such as skinfold measurements, circumference calculations and portable BIA devices, are inexpensive and allow you to be measured in your own home as frequently as you like.

The devices can also be purchased online easily, such as on Amazon. Most of the methods with highest accuracies are not available to use in your own home. If you want a more accurate assessment and are willing to pay for it, you could pursue a method with good accuracy like hydrostatic weighing, ADP or DXA.

Ideally, you should do the test before you have anything to drink, especially for methods that rely on electrical signals like BIA, BIS and EIM. Assessing yourself the same way each time will reduce error rates and make it easier to tell if you are making progress.

However, you should always interpret your results from any method with caution. Even the best methods are not perfect and only give you an estimate of your true body fat. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available.

Several dietary and lifestyle changes can help you burn body fat. Here are 12 great methods to promote long-term fat loss. It is a myth that a pound of body fat contains exactly 3, calories. This article explains the actual amount and what that means for weight loss.

Ann Nutr Metab 1 March Body composition evaluation tools 60 1 : 6— Composiiton is insufficiently detected in in- and outpatients, and this is likely to worsen during the next decades. The increased prevalence of obesity together with chronic illnesses associated with fat-free mass FFM loss will result in an increased prevalence of sarcopenic obesity. In patients with sarcopenic obesity, weight loss and the body mass index lack accuracy to detect FFM loss.
