After the excess food of the festive period, losing weight is a common goal. However, the number of pounds on the scale doesn't reveal much about your state of fitness. For instance, you can just as easily lose weight by shedding muscle as you can by burning fat. Rated at 4.6 stars on Amazon, the Innotech Smart Scale tells you exactly what is happening. The device uses bioelectric impedance analysis to estimate your percentage of body fat, muscle, water, protein, visceral fat, and bone density in seconds.
