I'm 48 yo. As a physician I have access to dexa and Tanita segmental BF scale MC-780MA (>6000 U$D).
I work out 6 times a week (combined aerobic/strength training) with average steady calories consumption of 1000-1100 kcal per training (according to my garmin 6x pro watch), have a clean diet
I did measurements 10 days ago. BF% on dexa is 20, on Tanita 20 and Garmin 31%.
I have same problems. There is absolutely something wrong with this scale BF% calculation.
