BIA (Bioelectrical Impedance Analysis)
Bio impedance is a relatively new technique that determines a current breakdown of the bodies individuals being water, fat and muscle weight within minutes. A much more insightful way of determining where weight needs to be influenced relating to specific issues.
Are your scales telling you the truth? Most likely not. But breaking down your bodies different issues into individual classes comes with the ability to monitor outcomes, and protocols can be more specific this way.
