I don't think that any sales person would like to hear that they would loose their commission and you would get the same results with something cheaper, so keep that in mind. Karen lost without any lites, so it can be done. Also my other thought would be to just not tell them, say you got them off e-bay.
I really wonder where that number came from, I would ask for it in writing next time, because at my old center i know they useto make up some of the stuff they said. Once they told me that their supplements are the only ones that can work with the diet, because other supplements aren't made for "healthy living" and one also said that they could actually feel the cellulite go away with the pills.
but you are doing great, just substitute for something similar like Luna bars, or ask about the plan with the more food, and if you don't like that go back to the lunas...work your plan to fit your needs.
