If a person is not succesfull in some accomplishment, it is because he has doubts about it and doesn't belief fully in the issue he is trying to accomplish.

It would not dawn upon a believing Jew to pick up Dairy after having eating Meat, because he is convinced and knows this is Halacha and there is no other choice.

This is exactly the principle of OA. If I truly belief that I am powerless over food, If I truly belief Step one: I have a chance to recover, however as long as I doubt it, and I think there might be another way I will pick up.
