How Accurate Are Body Fat Scales?

Body fat scales are devices that a person can use to measure
their weight and body composition at home. The term “body
composition” refers to the relative percentages of fat, muscle,
and water inside the body.
Understanding how much fat and muscle make up the body can be an
important tool for people looking to track their overall health.
In this article, we provide information on how body fat scales
work and whether they give an accurate estimate of a person’s
body fat percentage (BFP). We also outline alternative methods
for estimating BPF.
How do they work?

Body fat scales may give a person a rough idea of how much fat
is in their body.
Body fat scales use bioelectrical impedance analysis (BIA) to
estimate the relative percentages of different tissues and
substances within the body.
BIA sends a weak electrical impulse through the body. The
impulse encounters varying levels of resistance or “impedance”
from the different tissues and substances.
The scales then use a mathematical formula that incorporates the
value for electrical resistance with information about a
person’s age, height, and gender. People typically supply this
information via a smartphone or other electronic device.
The mathematical formula then estimates the relative percentages
of the following:
· total fat
· muscle
· water
· bone density
Fat offers more resistance than either muscle or water. As such,
higher resistance values tend to result in calculations of a
greater percentage of body fat.
Are they accurate?
Body fat scales provide a rough estimate of a person’s BFP.
However, they are not very accurate.
A 2016 study found that the BIA method of measuring body
composition is accurate when using standard, published
mathematical formulas. However, the body fat scale that the
researchers tested did not use accurate formulas to estimate
BFP. Therefore, it produced inaccurate estimates.
Also in 2016, Consumer Reports conducted a test of six different
body fat scales. First, the researchers used a lab-based machine
called a Bod Pod to take accurate body fat measurements. They
then compared these results with the data that they retrieved
from the home-use BIA body fat scales.
In this study, the home-use body fat scales either overestimated
or underestimated BFPs. The most accurate readings were off by
about 21%, while the least accurate were off by about 34%.
Pros and cons of using them
The primary advantage of using body fat scales at home is
convenience. The scales are easy and safe to use. Also, as long
as the scales are consistent in their measurements — even if
these are inaccurate — they can help the person roughly track
the effectiveness of their exercise regimen or diet over time.
However, body fat scales are not an accurate method for
estimating BFP. According to doctors, they typically
overestimate or underestimate BFP by a large amount.
Home body fat scales also cannot show where a person’s body fat
is stored. The location of body fat is an important
consideration when assessing a person’s susceptibility to
disease. For instance, a 2016 studyTrusted Source found an
association between increased abdominal fat and a higher risk of
developing cardiovascular disease.
But now！
Light&Move Tech has launched a brand new smart scale, they
called it smart scale 2.0.

The first smart scale can measure Bust, Waist, and Hip
This is a eight-electrode Light&Move smart scale. look the
appearance, its difficult to find out what is special about it,
but its truly incredible part is the measurement of body data.
The accuracy rate is almost the same as that of the professional
human body analyzers we use in hospital or fitness center, it
can detect up to 40 body data. The official description that it
matches the truly data as close as 97%. Let’s take a look at the
actual testing.

Summary
If you are a fitness enthusiast, or you are very concerned about
your body situation, this will be an explosive big news. You can
perform accurate body data measurement at home in the future.
You can monitor your real physical condition every day, and
throw away the false smart scale.
The BodyPedia is currently in production, and I believe it will
be available for purchase very soon, you can follow them to know
about the latest of this revolutionary smart scale on
