Fasting does have a place in your life. It's a Christian tradition dating back to Jesus. Your fasting also has to have meaning - it's never an end in itself as though suffering were good.
Fasting help put you int ouch with reality. There's something very real about hunger and it brings you closer to life itself. When you are hungry, you begin to appreciate that you are not a self-contained, independent being.
When you fast, you are anything but self-satisfied (although apparently that is how some Pharisees felt when they fasted). When you are hungry, you realize that you depend upon God's gifts to survive. You begin to put your life in context - that's something you don't do when your needs are met automatically, when your refrigerator or freezer is full, or when food is readily available at any nearby store. Hunger is an experience of helplessness. You experience your dependence on God and on God's gifts. It's a different way to look at fasting.
Hunger teaches you your interdependence on others. The food you eat depends on many people. A slice of bread is placed on the table through the cooperation of a wide variety of people.
Fasting helps you to appreciate all of that ... or at least it should.
