I did this one year and noticed that when they first measure you that they're holding the tape a little slack so that when they remeasure you the tape is held tighter so that it makes it seem like you lost a lot of inches. I also thought that this was the whole body when in fact it was only half body (you choose upper or lower), it was overpriced in my opinion (I've had similiar where I live and it's cheaper for the whole body). Don't know if this had anything to do with it but afterwards the next 3 days I was really sick, I don't know if it brought out the toxins in my body which made me sick or if I already had a bug in me and by doing this it brought it out. Personally, I wouldn't do it again, not worth the money spent.
