Your not having to calculate the 1/3 x 1/3 x 1/3...
What it means is to get a picture in your mind of your dinner in front of you like this...
1. A 2 cup salad (this is separate and supossedly eaten first)
2. A plate with 3 equal sections:
a) 1 section will hold cooked low carb veggies
b) 1 section will hold your meat or other protein
c) 1 section will hold your reward (desert,breadings or otherwise no-nos.)

Now This is just to give you a 'picture' to go by because your 'reward' may actually be a part of your drink or even a coating on your protein...so you have to 'equal out' the portions as best as you can at times. The main thing to remember is that this reward meal is NOT a 'free for all' to pig out on forbidden foods...it is to allow you a reward inside of a balanced (as much as possible) LC meal. If you eat it all and want more...you divide it up again the same way(maybe a spoon more of each instead of whole portions though)...Just finish it all in your hour.

What is really good about Low Carbing though is it is really a 'forgiving' woe at times. I have been following some of those with the best results in CAD/Calp/Atkins/otherLC and have seen some are having good results even though they are doing things slightly different than the 'exact' rules. The individualizations that work for them may or may not work for me or you but we can try things a little at a time as we go and see...but the main thing is to use the book, keep a journal, ask questions and get more strict if what your doing is NOT getting results.
If your addicted to carbs like we are this will work for you too.
