Why Hunger?

What's our problem with hunger? I've done a lot of pondering on this topic, and have come to realize that we were created with a need for hunger. When our bodies are done using what they've been fed, we are supposed to feel the trigger of hunger. The problem is, we are so used to either stuffing ourselves throughout the day, listening to diets and food plans that tell us when to eat and how much, bingeing on food to the point of feeling ill, or abusing hunger (anorexia)going after its starvation effect. Why are we so afraid to experience the normal function of hunger in our lives?
I believe we experience three types of hunger:
Body Hunger: This is the natural function of the body that uses up the food we ingest, and then needs to be filled again.

Spirit Hunger: The desire to be filled spiritually by communicating with God in prayer, learning from the word (the bible), fellowship with other believers, and experiencing the beauty of God within creation (nature, music, people).

Emotional Hunger: Eating to cover up an emotion such as boredom, loneliness, fear, anger, stress or frustration.

Many times we are really hungry spiritually, yet we stuff in food rather than turn to God. Sometimes we have an emotion that is glaring, yet we eat to cover it up and not "feel" it. Sometimes our bodies are just plain hungry, yet we deny our body the satisfaction of feeding it properly, or binge instead of listening to what our bodies need. Paying attention to what kind of hunger we are experiencing can start to undo disorder when it comes to food.
