Bioelectrical Fat Analyzer Using Microcontroller Atmega328

Abstract

Bioelectrical impedance analysis (BIA) is a useful method for determining the fat mass (FM), Fat free mass (FFM), and overall body water content (TWC) of the body. BIA plays a vital role in fitness and health care by measuring the body’s compositions. It’s easy for an individual to concentrate on particular part of body to reduce the body fat and make one’s progress better in fitness. Adiposity leads to major deadly diseases in our body including stroke and cardiovascular diseases. BIA gives an accurate result of body’s fat mass and total water content. BIA method is performed by passing very minimal amount of current about (500micro amps to 800micro amps) through different parts of body (hand, wrist, ankle and foot). The Electrolytes passes easily through water where FFM allows it quickly but FM doesn’t allow electrolyte to pass, as it contains low water content and have high resistance. FFM includes calculating extracellular water, intracellular water, bone and visceral protein, where FM gives the mass of body’s fat. BIA is a cost effective tool to maintain one’s health and fitness.
