From my own experience, I think the Atkins 40 is better suited to someone with more to lose versus less anyway. It is close to Dr. Atkins New Diet Revolution ongoing weight loss going to 40 carbs on the carbohydrate ladder (rung 4) which includes more veggies, cheeses, seeds and nuts, berries and melons. Some don't like to acknowledge that the good doctor did also say convenience foods were ok in moderation just check labels to make sure ingredients are acceptable and carb count ok.
So good luck to you, I know you will do great!
