BIA[1] actually determines the electrical impedance, or opposition to the flow of an electric current through body tissues which can then be used to calculate an estimate of total body water (TBW). TBW can be used to estimate fat-free body mass and, by difference with body weight, body fat.
Nevertheless it is not a "gold standard" or reference method. Like all assessment tools,
Simple devices to estimate body fat, often using BIA, are available to consumers as body fat meters. These instruments are generally regarded as being less accurate than those used clinically or in nutritional and medical practice. They tend to under-read body fat percentage.[2]
You asked if it can be measured accurately
I said yes, why wouldn't it
You said why not
I gave an example of how 14 year old kids can measure it at least semi-accurately if done in the right way
The implications of this are that there will be methods of testing bodyfat that are a lot more accurate than a teenager can do (EG a DEXA scan)
I'm sorry this upsets you so much. I don't even get why you're arguing lol. You find it hard to believe that we have the technology to measure that accurately? Why?
You know what I'm just going to put you on my ignore list as it's obvious here and your other posts that you like to contradict and argue for the sake of it and you also lack any reading comprehension skills.
Oni, i'm going to guess you are not a scientist?You started the argument by questioning what I was saying you dumb retard
Well in the pictures and videos you post up you look like you're carved out of stone. No way would l have thought you were over 10% bodyfat.
Oni, i'm going to guess you are not a scientist?
measuring fat/muscle/bone in the body to 0.1% accuracy by any means is not possible.
If we wanted to be really clever we'd make several measurements then evaluate the mean average and accepting an epsilon/delta error margin of 0.56, which would make things even more accurate.
Yes, why would technology be limited to only being able to measure to the nearest 1%
why? because we don't. within +-2% sure, within +-1% very doubtful.You asked if it can be measured accurately
I said yes, why wouldn't it because it cannot be measured accurately
You said why not
I gave an example of how 14 year old kids can measure it at least semi-accurately if done in the right way. "semi-accurately"? no such thing, and BIA is less accurate than DEXA, and based on DEXA results which are also innaccurate
The implications of this are that there will be methods of testing bodyfat that are a lot more accurate than a teenager can do (EG a DEXA scan) more accurate yes, accurate, no
I'm sorry this upsets you so much. I don't even get why you're arguing lol. You find it hard to believe that we have the technology to measure that accurately? Why?
What would you define as accuratelyYou asked if it can be measured accurately
I said yes, why wouldn't it?
I gave an example of how 14 year old kids can measure it at least semi-accurately if done in the right way
That's all you ever doI'm not going to argue semantics...
I'm not going to argue semantics about what I define as "accurate"
