Using body fat percentage rather than your weight when following a weight loss program can be more motivational and will also give a better indication of the increase in health. Probably the cheapest and quickest way to accurately measure and monitor body fat is by using calipers.
Skinfolds - Body Fat Calipers
Body fat or skinfold calipers take skinfold measurments on predetermined sites. The calipers pinch the skin and a measurement is taken to determine the thickness of the skinfold (or skin pinch) to determine your body fat.Best Calipers
Among the best skinfold calipers are the Harpenden Skinfold Caliper, Lafayette Skinfold Caliper, Lange Caliper, Accu-Measure Calipers, Slim Guide Skinfold Caliper.The body fat caliper measurement should be carried out by an exercise professional and repeated to give a reliable test. The skinfold measurement should also be taken before exercise since the increase in blood cirulation during physical exertion may cause the skin to swell. There are other options such as body fat scales, bioelectrical impedance, under water or hydrostatic weighing.
