DEXA is considered gold standard these days (even though I know other research facilities have access to various scientific machines that are supposed to be more accurate).
Wife and I do DEXA close to every 8 weeks and it does make a slight difference with visceral, android, gynoid, etc. Of he had a real analysis given after by someone, they would explain to him the differences of overall BF% versus visceral, android, etc. on the print out and I am guessing he is weighing heavily on the overall BF% given!
I would say he is close to 15/16% overall and obviously may have less fat around midsection, which is why you pay attention to gynoid and android.
My overall BF fluctuates slightly when I’m maintaining, so I focus on the areas versus overall.
