Jessica - on page 225 of DANDR, Dr. Atkins lists the carbohydrate increments - ....

So as you move up the carbohydrate ladder (as he puts it) ... if you increase 5g carb per day, every 7 days... this list will help you add those items... so that week 1 after induction you go to 25 g carb a day by adding something like:

Example: 15 almonds = 4 g
1 cup cauliflower = 5 g
1/2 cup spinach = 5 g

there's more on the list, check it out.
