Katie - Welcome! I wish you much success.. First, remember, with the amount of excersise you are doing, you are building muscle. It weighs more than fat (if memory serves me right). Measure yourself, if you haven't already, and watch the inches decrease!! The fats coming off, but the muscle gain won't let it reflect on the scale. Frustrating, yes, but don't let it get to you.. How do your clothes feel? Any difference? It will come off, just be a little more patient.
I have no advice about the Sanoma Diet, as i'm an Atkin's dieter myself, but I wish you lots of luck and great outcome.
