Im not sure where to post this but I was wondering if anyone used or know how accurate and how these scales work. I paid over 100$ for it and I love it but still not sure how it measures everything. BF% M% Bone mass and water. Thanks alot people.
It uses electrical impedance to send a small electrical current through your body. The current travels through the water in your body. When the current returns to the scale it measures the amount of resistance that it faced while passing through your body, and that resistance will determine your total body water content. Your water content is used to estimate your lean mass, and it calculates the difference between that and your total weight to give you your body fat%.
These scales will give you a rough estimate of body composition, but they are not terribly accurate. For instance, someone with a significantly low bodyfat% or someone with a significant amount of muscle mass will get an inaccurate reading.
another, you will get different readings depending upon how much food you have ate during the day or the amount of liquids consumed.
try it in the morning when you first awake. then try it later in the day, and you should have a some varience, probably one to two percent.
so although you can not count on these type of things to give an accurate reading, you can however depend on it to be pretty consistant and if you know the limits of this device you can turn it into a helpful tool that can show you results of changes in diet or training over time, keeping records of these things can be useful and something of value if you are doing a trial and error approach and experimenting to find what will work for you.
i was told electricity will take the shortest path, so it may not go through the whole body
Well from one foot to your waist and back down the other leg. I hold most of my fat in my legs, most likely gives me a high(but somewhat consistent) reading.
