Obesity has become a modern age disease and many peoplesuffer from it and its many consequences. Being overweight can damage thehealth of a person, and because of that fact many people exercise and watchtheir everyday diet.

According to the body mass index (or shortened just BMI),there are four categories of people. You can be underweight, normal weight,overweight or obese. All you need to do is to calculate the BMI and look at thecharts, to evaluate your body weight. However, this method doesn’t say anythingabout the percentage of fat in your body. This fact is also very important,because body fat, especially belly fat has been associated with increased risksfor your heart and many other organs in the body.

Measuring Body Fat

When you want to determine the percent of fat in the body,there are several useful methods. You could use DEXA (dual energy X-rayabsorptometry), Calipers (skinfold measure), hydrostatic weighing or NIR (nearinfrared interactance) or some other technique.

DEXA is commonly used to determine the density of the bones,but doctors found the same method useful for measuring the percent of body fat.Skinfold measurement includes measuring of skin thickness on different spots onthe body, especially chest or abdomen. Hydrostatic weighing is done underwater, and it is based on the premise that the person with more body fat willweigh less under water.

Underwater weighing and DEXA are considered accurate, butthese methods are very expensive and demand special facilities to bedetermined. Because of that, many people turn to body fat scale, less expensiveand similarly truthful method for measuring body fat.

Body Fat Scale

This method uses bioelectrical impedance analysis (BIA), andduring the measurement a very small amount of electricity has been passedthrough the patient. Fat tissue is more resistant to electricity than muscles,and that fact is used to calculate the density of the body and estimate amountof body fat.

Body fat scales are easily available, much less expensivethan other reliable methods for determining the body fat. Also, you can usebody fat scales regularly, at home, and monitor your everyday progress in fat loss.

The problem with body fat scale is the number of factorsthat could interfere with the results of measurement. Temperature of the bodyand the room, physical activity and amount of water in the body can significantlyaffect the results, and even if everything has been under control, the final percentof fat in the body still remain only rough estimation.
