I found this site to more valuable than the coaches. Mine is very nice and supportive, but she is a little dippy and at this point I feel more confident that I know more about the program than she does.
I am pretty sure that most of the drinks and the puddings are the lowest carb counts. I was surprised to see that the crispy cereal and omelette had 7 carbs each and the chocolate drink packet had 9. I am not sure how "magic" the 30 carb number is because essentially you could have (2) chocolate drinks and a restricted bar and be on plan and that would put you at roughly 33-35 carbs in IP packets alone.
What I try to do is just be smart about it and balance it out. If you like the chocolate drink, the ready made chocolate drink is delicious and is only 4 carbs. Also, the dark chocolate pudding can be made into a drink by add 10 oz. of water and I think that is 6-7 carbs. In the end, I think as long as you select 2 unrestricted and 1 restricted packet a day, you should be fine. But if I do have a chocolate drink, I try to balance it out by having a pudding or the orange drink as my other choice for the day.
