For starters I think it means your overall bodyfat % is 3%. It gives you your fat mass - 12st 5.4lb and your fat free mass - 5.6lb. Because if you put your weight in to lb's it is 179. Then divide it by 100 - 1.79 then times it by 3 (which is the bodyfat %) it equals 5.37, which is not far from your fat free mass measurment. That's the only way I could make any sense out of it all. TBH it doesn't so very accurate to me, 3% bodyfat ?
