This particular subforum is for questions specific to the Atkins plan, but you'll find that many people who post responses, while familiar with the Atkins plan, may not necessarily be following Atkins and will bring their own perspectives and experiences to their replies.
There are several low carb plans and they all have their different perspectives and good information on low carb in general which is why I will often encourage people to read books from other low carb plans. You never know when you will read something in a book for another low carb plan that sheds light on something that you may be experiencing on the plan that you are currently following. I firmly belive that no one plan has "all" the answers.
Definitely follow the plan that you are on as written until you are comfortable with it and low carb principles in general, but it never hurts to learn about other plans and perhaps down the road a bit incorporate principles from those into your low carb lifestyle as well.
