Hydrostatic weighing – This underwater weighing process estimates body fat by measuring your weight on land and in the water.These types of measurements can also be inaccurate because many things can impact the signal as it travels through the body including callouses on hands or feet, or how you hold or stand on the device. Fat will slow this down, while muscle, being a depot for water, will speed it up. These devices send out a low level electrical signal into a foot or hand and measure how long it takes the signal to travel to the other foot or hand. Bioelectric impedance – There are two main types of bioelectrical impedance analysis devices: one that you hold in your hands and body fat scales.More accurate skinfold calipers like Skyndex are several hundred dollars and can be cost prohibitive. It’s not uncommon to get a different body fat measurement when two different ‘testers’ take the same skinfold measurement on the same body. Cheap ones are easy to find, but they can get varied results on the skinfold measurements based on who’s doing the testing, the accuracy of the areas chosen for testing and their testing technique.
