After 4 months of pretty hardcore dieting, I lost 78 and decided to get my BF % tested at my gym. I also have a Tanita body fat scale at home that uses Bioelectrical Impedance Analysis to measure BF (or so they say!). I am 5'10" and started at 255lbs and ended at 177lbs. According to my scale at home I went from 41%BF to 19%BF... however when I got tested at my gym the computer gave me a reading of 9%. My gym uses a system from RJL Systems... this is supposed to be extremely accurate (or so they say!).
There is a pretty big swing between 9% and 18%... which one is accurate???
