I love the features on the Precision Go Fit Digital Body Fat Scale, because not only does it show me my weight, but I also have the option to get my body fat percentage, total body water, muscle and bone mass. The scale also stores up to 8 users so it is “Smart” in the way that we “Eat” by enabling us to keep track of who is losing what. The way that is does this is by sending a low-level electrical signal though your body fat and then measures the signal resistance. The lower the body fat, the faster the signal travels. How high-tech is that? You can find out more about this scale at Eat Smart Products and you can purchase through Amazon for 54.95. You can follow Eat Smart on Twitter and Facebook.
