Exactly how are you counting?  There are several newbie errors that
could account for this.

Are you deducting fiber but also using the cup counts from the book?
The cup counts predate fiber deduction.  One cup form the low carb
veggie list is 5 grams *minus fiber*.  One cup from the ultra low
carb veeggie list aka the salad list is 2.5 grams *minus fiber*.  So
if you eat a cup of broccoli and two cups of lettuce+cuke+etc, then
you are getting your basic veggie-half of 10 *minus fiber*.  Since
fiber deduction was added after the edition of the book, the cup
guideline became obsolete.  Eat more veggies.

Are you counting all dairy and eggs for their carbs?  Eggs are 0.6
each, cream at 6 per cup is 0.4 per tablespoon, cheeses run 1 per
ounce, etc.  It is extremely standard to get 5 from these sources
so if you aren't counting them that brings you down to 15 right
there when you're actually at the proper quota of 20.

Are you counting everything?  In specific, there are labels that
claim zero that are actually rounded down from 0.5 and next to
nothing is really truely zero.  A cup of decafe coffee is really
0.4 and so on.  If you carefully count each and every instance of
something going in the mouth that folks think of as zero, it
generally comes out to enough halves-rounded-down to total 5 for
the day.  So if you aren't counting them that brings you down to 10,
just like you claimed, but you are actually at the quota of 20.

In review: Quota is 20, mandatory at least half from veggies.

Enough veggies to total 10 after fiber deduction.  Two cups of
low carb veggies plus plenty of salad.  Subtotal 10.

The limit of 4 ounces of dairy, perhaps 3 oz cheese and 2 tbls of
cream.  Two eggs.  Count is 5.  Subtotal 15.

Coffee and so on that has labels claiming zero that is actually
rounded down from near 0.5.  Count is 5.  Subtotal 20.  Bingo.
