Normal eating does not need a meal plan. Normal eating is being able to eat when you are hungry and continue eating until you are satisfied. Normal eating is being able to use some moderate constraint in your food selection to get the right food, but not being so restrictive that you miss out on pleasurable foods. It is giving yourself permission to eat sometimes because you are happy, sad or bored, or just because it feels good. So long as you have other ways of satisfying these needs as well.
Normal eating is three meals a day for some, but it can also be choosing to munch along.
It is leaving some cookies on the plate because you know you can have some again tomorrow. In short, normal eating is flexible. It varies in response to your emotions, your schedule, your hunger and your proximity to food. If you eat foods that are good for you and get regular exercise, you won't necessarily be thin but you will be healthier and probably happier.
