lost 3 lbs from a couple of days age; weighed in at 186 on my new scale the lowest weight so far equal to 181 on my old scale but the body fat increased. read the manual on my tanita fit scan and it says the fat percentage is 5% accuracy meaning that it is off by 5percent on the high end so wondered if my body fat percentage is much lower than my scale readings. the scale is just good for using as a reference to know which direction your body fat percentages are trending.
