Something we don't often consider in our modern society. Is there a role for fasting in your spiritual walk? I think the scripture would say that there is. But remember, fasting is not only about food. The most important thing is that a fast is between you and the Lord. It is never something done out of ritual, a sense of duty, or for the benefit of others seeing you. Sort of like Fight Club: "The first rule of fasting is that you don't talk about fasting..."
Good discussions on fasting here and here.
