Hi, Mike. On the Accu-Measure chart, the body fat percentage for men goes up by about 1 percent for each five-year age group for the same millimeter readings. What’s the reasoning behind this? And what Accu-Measure labels “lean” in their chart (in the blue shaded area) includes a higher percentage of body fat for older groups. Does a higher percentage of body fat on an older man *look* leaner than the same percentage on a younger man or are they suggesting percentages for optimal health? I couldn’t find anything on the Accu-Measure website that addresses either question.
