Frequently Asked Questions

- How does a body-weight scale calculate my body fat %?

Digital scales work with the help of sensors placed underneath feet that use a small non-harmful electrical impulse to measure impedance.

When stepped on the digital scale, a small electrical current runs up through leg and across pelvis, measuring the amount of resistance from body fat. It is said that greater body resistance means a higher fat percentage. Because the fat contains less water than muscle, so it’s denser than muscle and more difficult for a current to travel through.

The accuracy of digital scales is based on the quality of manufacture and their instruction to be followed to get accurate reading. For example the presence of clothes, electronic devices such as cellphone, shoes and any other thing such as wallet or bags may change the results. However other factors are gender, pregnancy, age and height and posture.

The greatest benefit of using digital scale is that one can measure body fat in the comfort of own home at any time, without going to a gym or clinic.

Can you consistently track your body fat % and muscle mass with a body composition analyzer?

The most consistent and easiest approach to weighing is getting on the scale with less additional weight like clothes, watch, shoes. If that’s not an option, at least one has to be consistent all the way.

For example, if you wear shoes, try to wear the same shoes every time. Weighing after physical activity will result loss of water through sweating. This is why one of the best times to weigh is in the morning before eating or exercise.
