What is Normal Eating? To quote Ellyn Satter, MS, RDN, and recognized authority on nutrition for families:
“Normal eating is going to the table hungry and eating until you are satisfied…
Normal eating is being able to give some thought to your food selection so you get nutritious food, but not being so wary and restrictive that you miss out on enjoyable food…
In short, normal eating is flexible. It varies in response to your hunger, your schedule, your proximity to food, and your feelings.”
