i did it quite successfully (and then had another bub so all my hard work gone) - it is quite expensive to start if you follow meal plan as per book - if I do it these days I adjust the meal plans and chose dinner options that we would normally buy or used similar ingredients. I used to put up the meal plan for the day and as I had something ticked it off thus not necessarily sticking to the three meals but using the dessert fruit and dairy allowances and even some of the lunch meat as snacks throughout the day and thus over the day having the required amount of food rather than the three distinct meal times.

Basically if you can develop a meal plan that meets the daily allowances (but mix it up a bit for variety which I find is the key to keeping me happy when losing weight) you don't need to follow the meal plans as developed in the book. I do like the fact that the menu options are there though to give you different ideas on how to prepare meals with less carbs (that was our problem).
