I do not have Dr Westmans book, but do have several copies of the old ones authored by Dr Atkins. Over the years I heard the newer book had major differences. Maybe this is one.

Atkins is 3 cups of vegetables. 3 cups loosely packed greens; or 2 cups greens and 1 cup of allowable vegies.

There is a sticky that contains the INDUCTION rules at the top of this Atkins section .

Atkins was a proponent of eating your vegetables; and IMHO eating as many as possilbe and still attain your goals is the way to go.

Hope this helps.
