I apologize if this is a repeat question. I have read the book, tried searching this forum, gone to the Hellers' site and read the stickies -- I really have tried to find the answer -- what I have found was worded in a confusing way though.

Is the rule of thumb for each Complimentary Meals to eat 4 or fewer net carbs? or total carbs? or does this "4 carbs" phrase I have seen frequently mean that you should not eat any food with more than 4 carbs per serving at a CM, with no specific limit of total/net carbs per CM?

Thank you in advance for your help!
