Tanita feels it is very important for people to fully understand the benefits--and limitations--of body composition analysis. This information will enable people to make better decisions about which method is the best cholesterol or most appropriate for their particular needs. Reference Models Measurements of body composition are based on theoretical body composition models. The more traditional methods are based on a two-component model that simply divides the body cholesterol into fat and fat-free mass. Newer, more sophisticated techniques measure the body as multiple compartments consisting of water, protein, bone mineral, and fat. This approach improves the accuracy of the calculation for determining the real density of fat-free mass. There are two basic body-composition models: the two-compartment model--fat-free mass and fat; and the four-compartment model-- bone/mineral, protein, water, and fat. Equation Formulas The equations used in predicting body composition have been developed using regression models that take into account data from many different research projects.
