Many bodybuilders, and general fitness exponents, keep their body-fat at around 8-10-percent (within striking distance of a competition, or simply to look good year round). How Do Body Fat Scales Work? They work with the help of the underfoot sensors that use bioelectrical impedance. The chart below takes a look at the best body fat scales and lets you find the products that work best for you. But body fat scales wrongly assumes that the density of various tissues is the same from person to person, and remains constant over time as you lose weight. Body composition measurements include body fat, muscle mass and and metabolic rate, and over time the user can see, in detail, the results of their weight loss or fitness programme. Fat contains less water than muscle and provides more resistance due to its higher density. How do the digital body fat scale work? In short, electricity. Copyright Policy So how do body fat scales work? Measuring body fat percentage is a better indicator of how well your diet and exercise program is working. How do body fat scales work?
