Body fat scales and accuracy
August 21, 2020
Body fat scales and accuracy, is one of the big topics that people are debating about these days, when they see all that body fat scales can do .
Some people exercise on a regular basis, eat healthy food to lose weight and yet don’t see any change, when they look at their body weight on the scale. The reason this happens, is that exercising strengthens the muscles which also means an increasing muscle mass despite a body fat loss.
When this happens to someone, it may be a sign that they need to measure their body fat percentage instead of just the body weight.This is how they would be able see what is going on inside their body and see if all the hard exercising and discipline are paying off .
These smart scales can tell the user about their health.They show the user the healthy ratio fat VS muscles and where they are standing based on their measurements data .
Although they can do a lot of nice things,they are not perfect.Nothing is perfect here on earth .
Since they can measure a lot of things, someone could think they don’t need doctors anymore, to know about their body composition data.Who knows ?It could happen someday. However, for now,they are mostly for home use, while a person is waiting for the next visit to their doctors or personal trainer.
How do body fat scales work ?
Body fat scales work differently from old body weighing scales.One of the thing they have in common and which i think can be guessed ,is the fact that a person has to step on them,wait a little bit,until the measurement is taken .
For the old weighing scales,the person who is taking the measurement, stands on the scale, steady,with no shoes or heavy clothing,until the needle stops.An old scale has a screen with numbers around a turning needle,it looks almost like a big clock .The weight of the person would be the number where the needle has stopped after a person has stepped on the scale .
Body fat smart scale can take the measurement in seconds.When a person steps on the scale,a weak ,small and safe electric current, is released from the scale, goes through the leg of the user,travels through the whole body from bottom to top, before going back to the scale through the other leg. The current which travels through the body, experience a natural resistance from body fat.A body fat scale usually has sensors which are used to measure the level of the resistance,the current encountered while traveling through the body .
Smart body fat scales, usually have a nicer design than the old scales,they are also lighter and easy to carry around . Most of the time,these scales work with an application of their own, to connect with phones,tablets ,smartwatches and other devices . The measurement results from a smart body fat scale ,are displayed directly on the screen of the connected phone or tablet ,where they can be accessed easily ,studied,tracked and more.
What is the body fat percentage ?
The body fat percentage of a human also known as BFP, is the total mass of a person’s fat divided by their total body mass.To get a percentage value, the result of the division is multiplied by a hundred.A person can’t live without body fat and a risky level of body fat percentage can affect the reproductive ability . Women naturally have a higher body fat percentage than men because their body is designed different, they can bear a child and their hormones have different functions.Storage body fat are from an accumulation in adipose tissues, a part of them protect internal organs in the chest, abdomen and arms ( Lungs, veins , stomach,skeleton ,kidneys ,etc).The body fat percentage is very efficient in measuring the fitness level of a person. The body fat percentage and the body mass index (BMI) are the most used to measure other body composition index.The BFP measures without using their height and their weight of the person and it can be measured in many ways. It can be measured using calipers per example or bio electrical impedance analysis (BIA)which most body fat scales use .
What is the body mass index (BMI )
The body mass index (BMI), can be used to determine also the body composition of a person. However,BMI uses the height and the weight of a person for the measurement.The BMI can be very efficient when measuring a large group of people to determine the big health picture of everybody but it sometimes can’t provide that many informations on the fitness level of a single person like the body fat percentage measurement does. The body mass index measurement can be affected easily by the muscle mass and the size of the bones of a person .
What is a safe body fat percentage range ?
Here are the different ranges of body fat percentage starting from what a person naturally needs to live, to the range where a person could be in danger, of getting health problem, because of their body fat :
- Essential fat are between 10 and 13 percent
- For people who are more active,like athletes, with a higher muscle mass,they have between 14 and 20 percent
- If a person has from 21 percent to 24,it means they are generally, in a fit condition .
- 25 percent to 31 is considered acceptable for a person who is less active
- Above 32 percent of body fat, a person could obese, depending on their age .
Here is the right body fat percentage,based on the age of a person :
- For someone between 20 and 39 years old, the right range of body fat, should be between 21 to 32 percent .
- For a person who is 40 years old,up to 59,their body fat should be between 23 to 33 percent .
- As a person ages, their body fat increases, while their lean mass and bone mineral density decrease. A 60 years old person should have between 24 to 35 percent of body fat and should stay in this range until when they are approaching 80 years .
How accurate are body fat scales?
To sum up,body fat smart scales are usually accurate .While some people say that they are not accurate enough , these scales depend on many variables when measuring, to give the user the best accurate result and best experience.The reason why some people say this,is probably due to how these scales are designed to function. When a new user is setting up a body fat scale,they need to enter correct and exact information regarding their body (Height ,Gender, Age , etc ).If one of these information is mistaken,results from the body fat scales are probably going to be wrong to a certain measure.In such a case, the scale tries to stay in the reasonable measurement range .That is why sometimes the user can get two different measurement results .Here is a suggestion ,if a body fat scale gives two different measurements, it means that the right result is the average of the two, because it always tries to stay in the right range of measurements, depending on the personal information interred while setting up the scale.Although the set up process is very easy and takes like 2 minutes max,it is one of the most important part of using these body weight scales.
Are you an active person who like to exercise ?Are you a kid or an adult?Are you pregnant ? These are some questions which can also be answered in the setting up process.These scales usually have different modes to fit everyone,they have many more nice features ,check out the best smart scales in 2020 for more.
