Smart scales have gained popularity in the health and fitness industry due to their advanced features, such as body fat measurement. But, can you rely on the accuracy of the readings provided by these scales?
To understand the reliability of smart scales in measuring body fat and the trustworthiness of their readings, it is important to learn more about their technology and methods.
How do Smart Scales Work?
Smart scales are digital bathroom scales that use sensors to measure various fitness indicators, including weight, body fat percentage, and BMI. The scale sends this information to a companion app on your smartphone, where you can track your progress over time.
There are a few different types of sensors that smart scales use to measure body fat percentage. The most common is bioelectrical impedance analysis (BIA). BIA works by sending a small electrical current through your body. Since fat conducts electricity differently than muscle or water, the resistance of the current can be used to estimate body fat percentage.
Other sensors used on smart scales include skinfold calipers and optical scanners. Skinfold calipers work by pinching the skin and measuring the thickness of the subcutaneous fat layer underneath. Optical scanners use light to estimate the percent of the light reflected off your body, which can be used to calculate body fat percentage.
The accuracy of smart scales can vary depending on the type of sensor used and other factors, such as hydration levels. In general, BIA-based scales tend to be more accurate than skinfold caliper or optical scanner-based scales. However, no matter what type of sensor is used, smart scale measurements should be taken with a grain of salt and not used as the sole basis for making health or fitness decisions.
However, knowing your body composition is a good way to understand your overall health, which can be easily done through orthodox ways of visiting your doctor, but the real question in today's advanced world regarding BFP is how accurately your body fat can be measured with a smart scale and can this method be trusted.
