BMI Bathroom Scales Are Not Accurate Stating Your Body Fat

Fitness has gone high tech and that includes your bathroom scale.  No longer does it simply give you weight, it transmits your weight to your fitness tracker and plots out your progress on a flow chart.  Some scales go a step further in showing your body fat percentage or BMI. The problem is that number is widely inaccurate.  Even a body fat scan isn't a true measurement of body fat.  The only way to truly measure your body fat is to have all of it stripped out, placed on a scale, and weighed. The only downside is that you have to be dead in order for it to happen. Your smart bathroom scale uses a method known as bioelectrical impedance to determine your body fat.  It involves running a light electrical current through your body, and measuring the degree of resistance (or impedance) to the flow of the current. The first and perhaps most obvious problem with body fat scales is that they miss out large segments of your body. Stand on a set of foot-to-foot body fat scales, for example, and the current will simply go up one leg and down the other. Which means that you’re only measuring how fat your legs are. At best, a body fat number should be viewed as a prediction than a measurement. In other words, it is an educated guess much like predicting the weather.
