FFMI has nothing to do with having low body fat. It's literally the exclusion of fat from the index. You can have a high FFMI and a high BF%. A few years ago I had a DEXA scan done to assess my starting condition prior to starting an exercise regime. That scan showed me as having 30% body fat at a body weight of 260 lbs. Being 6'2" I had an FFMI of 23.4 and an AFFMI of 22.9. My calculated BMR at the time was in the 2200 kcal/day area. (Might be misremembering the BMR, but it definitely wasn't in the high 2000s.)
