Dewed - re apple - its what weight watchers used to tell us. If your hungry but your only hungry for a cookie, you are not really hungry - you just have "mouth hunger" for a cookie! If you were really hungry, an apple would sound good, not just a cookie (or whatever "bad" food).
The weight watchers coach once gave me heck for eating protein with my snack, saying that made it a meal. NOW they say you SHOULD eat protein with a carb or fat snack, to never eat them alone!
I mean, they super-shamed me those witches. So you do you.
