Bioelectrical impedance analysis (BIA) is a widely used method for estimating the human body composition. The technology is relatively simple, quick and noninvasive. BIA is currently used in diverse settings, including the U.S. Military, health practitioner offices, health clubs, and hospitals, and across a spectrum of ages, body weights, and disease states. Despite a general public perception that BIA is merely a measurement of “body fat”, the technology actually determines the electrical impedance of body tissues, which provides an estimate of total body water (TBW). Using values of TBW derived from BIA, one can then estimate fat-free mass (FFM) and body fat. In addition to its use in estimating body fat, BIA is beginning to be used in the estimation of body cell mass and TBW in a variety of clinical conditions.
BIA measures the opposition of body tissues to the flow of a small alternating current. Impedance is a function of two components: the resistance of the tissues themselves, and the additional opposition (reactance) due to the capacitance (cell charge energy) of cellular membranes.
Application of BIA increasingly use multi-frequency measurements, or a frequency spectrum, to evaluate differences in body composition caused by individual subject’s clinical and nutritional status (e.g., “phase angle” or ratio between “reactance” and “resistance”, ratio between moisture inside the cells, or “intracellular water” (ICW), and moisture outside the cells, or “extracellular water” (ECW), and “parallel capacitance” or ion concentration gradient essential for cell survival.
Is BIA Safe?
Users of the BIA procedure consider it safe because of several factors. One factor is that currents at frequency of 50 kHz are reported to be unlikely to stimulate electrically excitable tissues, such as nerves or cardiac muscle. Another is the absence of any reports of untoward events induced by BIA, even in the course of thousands of individuals undergoing measurements. A third factor is that relatively small current magnitudes are involved, less than 1 mA, which are less than the threshold of perception. Furthermore, the use of batteries of low-voltage power sources greatly diminishes risk.
Because of the accessibility and widespread use of this technology, the National Institute of Health Office of Medical Applications of Research and the National Institute of of Diabetes and Digestive and Kidney Diseases, along with the National Institute of Child Health and Human Development, the National Institute of Aging, the National Heart, Lung, and Blood Institute, and the United States Department of Agriculture, convened a technology assessment conference to evaluate the validity and interpretation of data derived by BIA for the estimation of body composition. The conference brought together scientist with expertise in a variety of disciplines including nutrition, epidemiology, physiology, metabolism, biomedical engineering, and the clinical practice of medicine. The instrumentation for BIA, along with variations in techniques for its use, was examined in detail. Variables influencing the measurement of BIA and the need for standardization of testing conditions were considered. The applicability of BIA to a variety of conditions in both health and disease were examined.
BIA provides a reliable estimate of total body water under most conditions. It can be a useful technique for body composition analysis in healthy individuals and in those with a number of chronic conditions such as mild-to-moderate obesity, diabetes melitus, and other medical conditions in which major disturbances of water distribution are not prominent.
To validate Defiance Fuel ultra hydration delivery system technology it is recommended that an inexpensive BIA is conducted when beginning the use of Defiance Fuel functional beverages. A subsequent BIA administered 14 – 30 days later will demonstrate an improvement in ICW/ECW ratios and phase angle. Phase Angle is a BIA test that indicates overall cellular health.
What do your BIA results indicate?
The BIA yields resistance and reactance measurements which translate to phase angle, an indicator of cellular health and integrity, which should optimally measure 7+, ICW/ECW ratio which is optimally measures 60% ICW and 40% ECW and cellular parallel capacitance which in optimum health states measures over 1,000 pico farads. These numerics are a snapshot of overall cell energetics.
What is the simplest way to begin increasing BIA results or healthy body numerics?
Ingest a minimum of 1 liter of Defiance Fuel ultra hydrating solution daily.
What else do I do and how long?
High potassium low sodium diet filled with dark green leafy vegetables, daily exercise and regular bedtime for at least 60 days but, you may see BIA improvements in 14 days or less.
What is happening in my body when all of this change is taking place with phase angle and cellular capacitance and how does that translate to a healthier body?
Moisture is redistributed internally thereby increasing your intracellular water to extracellular water ratio which compliments whole body restoration.
