InBody520 Composition


We Use the Latest Technology: InBody 520 Body Composition Analyzer

Weight alone is not a clear indication of good health, because it doesn't distinguish between how many pounds are fat and how many pounds are lean body mass. At Advanced Medical Weight Loss Augusta we use state-of-the-art technology to help us plan your medical weight loss program.



The information we gather using this technology can tell us if you are at a higher risk for heart disease, sleep apnea, osteoporosis or metabolic syndrome (Syndrome X).

We evaluate our patients in a variety of  ways. To facilitate our pre-program testing we use Bioelectrical Impedance Testing (BIA) using the InBody 520 from Biospace, the leading manufacturer of  physician-grade BIA devices. We use it to perform regular comprehensive body composition testing on all patients.

The InBody 520 has achieved a .98% accuracy correlation with DEXA, the gold standard in body composition analysis.

This technology provides a lot of insight into our patients' metabolism, while it accurately measures the overall weight. It also goes much further by providing the composition of that weight by distinguishing between Fat Mass (FM), total body water and Fat Free Mass (FFM), which is everything except fat and total body water.

Technically, the InBody 520 determines fat from water and lean muscle by testing the body's resistance or impedance to a mild electrical wave sent up one leg to mid torso and down the other, which then does the same thing for each arm. In this way, the Inbody 520 not only determines overall body composition, but can determine body composition for each of five segments, two arms, two legs and the torso. Fat provides more resistance than water which is a better conductor, so from this the InBody 520 can determine the Total Body Water (TBW) and then predict the Body Fat Percentage (BFP).

Men have 3-5 percent essential fat and their ideal range is 12-20 percent BF with clinical obesity starting at 25 percent. At 29 percent BF most men will have metabolic syndrome (insulin resistance). Women have 10-15 percent essential fat and their ideal range is 20-30 percent BF with clinical obesity starting at 33 percent. At 37 percent most women will have metabolic syndrome.

Beyond body composition testing, waist and hip measurements can provide very useful information. There has been considerable scientific evidence that the amount of fat accumulation around the waist is more dangerous (metabolically) than fat elsewhere in the body. Women who have a waist circumference of 35 inches or more and men who have a waist circumference of 40 inches or more are at increased risk of cardiovascular disease. These are just some of the ways we evaluate the patient's risk for disease as well as their overall progress.

More About the Technology

InBody uses 8 polar tactile electrodes where a different electrical voltage and current are sent through the inner body, resulting in five different impedance readings for the body’s trunk and four limbs. This exclusive in-depth analysis of the InBody yields accurate results for total body composition, and is able to measure segmental muscle mass as well. Its segmental analysis method is world wide patented technology.

Accurate impedance measurements of the trunk is key to bioimpedance technology and no population specific statistics (empirical factors) are used in calculation. High accuracy is guaranteed by precisely assessing your trunk.

All data solely depends on the measurements, not relying on gender or age. Multi-frequency measurement provides the precise amount of body water: ICW (Intracellular Water) and ECW (Extracellular water) Exact measurement of body water guarantees accuracy. Evaluation of Edema is important to monitor the balance of body water.

The Tactile Electrode System ensures an enhanced accuracy by fixing the measuring region. The fixed measuring regions of the body guarantee high reproducibility, also minimizing error rates due to different placement of electrodes in your hands and feet.
