From what I read on the boards/in books, it's not good to keep confusing your metabolism by chopping and changing. This is a way of life and you need to be convinced that it's right for you if you are to be happy to stay with it for the long haul. I'm convinced that it works for me - maybe you might read up some more so that you can muster the arguments for yourself first and then you won't feel so vulnerable when your family attack it. Losing weight healthily without hunger and keeping it off is a great way of having the last word!
