There is Body Fat% tracking and always was. And it is used for the Fitness Age, when available. You just either have to use a Garmin scale, or import the Body Fat% data in a CSV file. Check the "Related" threads on the right side of this page, if you do not know how to do it exactly. There are plenty of threads discussing it.
Weight-in page does not have Body Fat %, so it's not there. Quite disappointing. I'm not buying another scale, but I will look at the CSV workaround, at least that's something.
