Normal eating is positive and enjoyable. Normal eating will be flexible eating and depends on your internal cues of hunger, thirst and satisfaction. It's a way that grows out of trust - trust in yourself to eat in a way that's right for you, based on how you feel. It's the opposite of being on a diet and having a book dictate what you eat. Normal eating is giving yourself permission to eat sometimes because you are happy, sad or bored, or just because it feels good.
Normal eating means eating regularly most of the time.
It can also be choosing to graze at a party. It is leaving some cookies on the plate because you know you can have some tomorrow. Or, it is eating more now because they taste fresh. Normal eating is overeating at times -feeling stuffed and uncomfortable. It is also undereating at times because you are busy or sick.
