I'm not sure if you can answer this here but I just heard you speak on the Better Life Summit with Chef AJ and heard you speak about the fat % scale. I was wondering how accurate this scale would be for me since I have 2 steel rods the length of my back. I hate to purchase one if it is not going to be accurate. I know I am a little overweight but since I don't feel that BMI is accurate for me because of my scoliosis, I was hoping this scale could give me a better picture.
