There are currently dozens of “body fat scales” on the market.

They use a new technology that is called “bioelectrical impedance” that measures how much body fat you have.


The newer devices send a small electrical current through your body, and as the muscles in your body conduct electricity better than fat, the greater resistance your body has to the charge, the more body fat you have.

The BIA analyzers or “smart scales” can be programmed to set the data based on your height,age,gender and weight, and they give you a reading that is normally based on the average person based on your attributes.

Most of the modern scales can be hooked up to a PC or App on your smartphone, so that you can keep track of your progress.

How precise are smart scales?

One of the main issues with a lot of smart scales is they are sometimes inaccurate, especially the cheaper options.

Other important factors can affect the results, these include, whether you have just ate, if you just exercised and even if you feet are clean!


Most models can give slightly different results depending on what type of surface you are placing the scales on, the harder the surface, the better the results is the normal practice.

Do you need a BIA Analyzer?

According to most health experts, the healthy medium should be between 11 to 22 percent for middle aged men, 22 to 33 for middle aged women and 25 – 35 percent of an older aged woman and  15 – 25 for an elder gentleman. – see: ideal body fat
