Bodystat is dedicated to researching bioelectrical impedance technology to provide the best, most advanced electronics that accurately measure body composition and hydration within the human body, non-invasively.

With over 80 years collective in-house experience in Bioelectrical Impedance Analysis (BIA), Bodystat can confidently and proudly not only give you the electronic measurements, but also the explanations required to analyse the data through a thorough understanding of BIA technology.



BIA (Bioelectrical Impedance Analysis) is a measurement of the opposing flow of current at a particular frequency (strength of current) through any biological tissue. When the resistance to the flow of the current in tissues (ie their insulating properties) is high, the impedance value seen on the device is reflected as high. The impedance values are then used within gold standard validated regression equations, and the quantity of those tissues in a given body can be calculated for fat, muscle and water. For example, fat has a high resistance due to the small amount of water present in the adipose tissue. This makes fat a poor conductor of current and will give high impedance readings. Lean muscle mass has a low resistance, since it consists largely of electrolytes and fluids. At higher frequencies, additional tissues/cells can be measured including intra-cellular and extra-cellular water (i.e. the body’s internal and external cell hydration. Using spectroscopy at the higher frequencies will calculate the volume of over-hydration.


Body Mass Index (BMI) is no longer believed to be an accurate marker for health or weight management. BMI uses total body weight (kg) divided by height squared (m2), however the total body weight does not account for the different proportions of fat or lean muscle. If you are muscular or short in stature, your BMI will be high and you could be wrongly classified as obese or unhealthy. BIA is widely considered the most accessibly accurate method for measuring body composition within the fitness, nutrition, health and medical fields around the globe.


Essentially, body composition refers to the different proportions of body tissue in your body: body fat, lean muscle mass and water*. BIA can measure each of these compartments, and including *total body water, can also give measurements of water inside the cells and water outside the cells. A valuable marker within BIA is called the Phase Angle, which measures the integrity and functioning of the cell membrane, clinically associated with nutritional status. Bodystat is unique in that the Phase Angle (or Phase Shift) is measured (not calculated) which is now used internationally as a prognostic indicator of health/survival, muscle quality and nutritional assessment.

Bodystat’s trademarked Prediction Marker, accredited in the ESPEN Blue Book as a “a newer way to evaluate cell membrane function”, has been shown in recent ICU studies to be a reliable guide to prognosis. Patients who died in ICU or during hospitalisation had significantly higher Prediction Markers than patients who survived.*


Bodystat Limited started with humble beginnings in 1990 run from the family home by pure passion, drive and belief in the technology. Over the years, the company grew and now owns its own office block sitting proudly in a prestigious location in one of the island’s largest business parks.
