I have one of those Tanita IronMan scales and I know the only thing it tells you directly is your weight -- everything else is based upon equations and population studies related to bioimpedance. But it is helpful to track your trends. Mine also has something called "Metabolic Age" that you might presume is a kind of overall fitness measure. So during this cut I am now down to a metabolic age of 32!! Yeah, it's voodoo, but at an actual age of 47, I can't help but feel good about it. OK, just a little something to celebrate!
