According to recent research it has been observed that people who measure their body fat on a weekly basis while working out and dieting reach their health goals sooner compared to people who take regular measurements. There are different weight measuring instruments available in market and the latest among them which is currently most popular is the Electrical Impedance Body fat machine.
When you step on the sensors using in the scale an imperceptible electrical current passes up one leg moves across the pelvis, and then down the other leg. Due to it containing much more water, muscle conducts electricity better than fat does. So, simply the rule is that greater the resistance, the more body fat you have. The scales use different pre-defined formulas to calculate a body-fat percentage from this resistance information, along with other data that you enter (height, weight, age, and gender). Some other scales also include hand electrodes to better estimate overall body fat. An increasing number of models come with fancy features such as wireless transmission of data to your computer or smartphone. Nowadays these scale techniques are widely used in the market but in this article we will see whether it is worth it or not.
How much accurate are they?
There are problems associated with these scale machines just like others and sometimes they go inaccurate. The major problem is that many variables affect the results, including how hydrated you are, when you last ate and exercised, and even whether your feet are dirty, as well as the type and quality of the product itself. Different studies have now found that different body-fat scales produce widely varying readings and that these often differ from standard methods of fat measurement. In a study published in Obesity Facts in 2008, scales with only foot electrodes underestimated body fat in people with lots of body fat and overestimated it in leaner people. Even the manuals say that the devices may be less accurate for elderly people, highly trained athletes, children and people with osteoporosis, among others. The scales that make use of people to stand on them with both feet offer far greater accuracy.
Are they beneficial to use?
This purely depends upon whether you need to know your body fat or not. True, body weight can be deceptive because it doesn’t indicate how much the reading is from fat and how much is from muscle. But there’s no widely accepted standard for ideal body fat; it depends on age, sex, fitness and ethnicity. According to some experts, a “healthy” range is 23 to 33 percent for middle-aged women, 11 to 21 percent for middle-age men and up to 35 percent for older women and 24 percent for older men. Athletes typically have much less body fat.
Also a lot of researchers says that the body-fat scales can be useful for tracking body fat changes over time and that they can help motivate some people to lose weight. So, if you want to reach your health goals a lot sooner it is a good idea to invest in a body fat analyzer in order to keep a record of the weight you’ve lost or gained depending on the workout regime you follow.
