Over the weekend I bought this portable bodyfat analysis. The box of the device says its accurate to about 0.1%. The device measure the bodyfat by sending a bioelectrical signal through the body to determine the percentage. I’ve been checking my bodyfat percentage the past couple of days and it has average about 5%. I sometimes question the accuracy of the device because 5% is low and is usually reserve for world class athletes or mal-nutritioned individuals in third-world countries.
