What would you define as a "healthy relationship with food"?

Sorry for all the food-related questions… it just seems like Fluther really knows about this subject!

I hear a lot of talk about maintaining a “healthy relationship with food.” What does this phrase mean to you? How would you define a healthy or unhealthy relationship with food?

Is it purely a matter of making sure you get the right number of calories each day – not too many, not too few? Or is it also mental, like not being excessively hard on yourself, too lax with your caloric limits? What about being mentally dependent on food – would you consider not being able to study without food an unhealthy relationship, or a habit of midnight snacking?

Do you know anyone who you feel has an unhealthy relationship with food, and if so, why?
