Hi Amy,
Not Cathe, but I can try and help. I own a body fat scale, probably one of the best on the market. It works really well, however even so, these scales work on a bioelectrical feedback which is greatly affected by the water content in your body which can vary greatly anytime simply by what you are eating and have an error ratio of
+5% or -5%! My best suggestion is to go to a reputable gym to a trainer who can use the calipers on you, this way you have an ACURATE base line for the future. I did this and he gave me a reading of 16%, I then came home and checked myself on my scale and it told me 19%! I hope this helps.
