Measuring the exact amount of a person's body fat level is not easy. The most accurate measures of body fat are weighing a person underwater or inside a chamber that uses the principle of air displacement to estimate body volume, or to use an X-ray technique called DEXA. Body fat mesaurements need not be so complex. There are many simpler methods to estimate fat content of the body. One is to measure the thickness of the fat layer just under the skin in several parts of the body. Another involves passing a small amount of electricity through a person's body. Results from these methods, can however be, less than accurate especially if done by an inexperienced person or on someperson with high level of obesity.
Because directly measuring body fat is cumbersome, physicians and other health care workers often rely on other methods to make a diagnosis of obesity. These include weight for height charts, and body mass index estimations. These are good estimates of a person's body fat content even though less accurate than direct measurements.
