Impedance body fat analysis had a lot of problems, I’ll just get into one:
The measurements, even the palm to feet ones on big machines in medical settings with handles, are based on a known level of how much human skin conducts electric currents. I’m part of a genetic group that I’m missing one of the 5 types of collagen and so my skin conducts electricity differently and the impedance machine gives me the exact same 44% BF reading regardless of my actual weight. My doctor had to tell me that impedance BF measurements will never be accurate for me so I have to have a DEXA or skin fold if I want to know for sure. This would have been fine if I hadn’t already spent years believing those fucking devices that thinking that even though I was losing fat, I must be doing something wrong be the impedance scale didn’t change as they were “scientific”.
They aren’t that accurate for the whole population, and we don’t actually know what percentage of the population they are accurate for because no one has bothered to check.
