During the "induction" period, the book specifies to only have 3 cups of lettuce per day (if no other veggies are consumed). When I looked up Romaine lettuce in the carb-counter, I found it only had about 4 grams of carbs in 3 cups. If 20grams of carbs are allowed per day, why should I only allow 1/5'th of those to be lettuce? I've been following it fairly strictly none-the-less, but I was just wondering the reasoning behind it.

Have a great day!
