Here's how we're seeking God as a church:
Take time right now and ask God what you are to be specifically believing for as you step into the fast. Then, ask God how you are to fast. Are you to do the "Daniel Fast" of only fruits and vegetables? Maybe an all liquid fast (consult your physician first)? God may direct you to fast a specific meal each day or to not eat sweets or carbs. (Hopefully not coffee ;-) God may direct you to fast all media: TV, internet, social media, ETC. However God directs you to fast, be sure to enter into it prayerfully and full of faith.
Prepare yourself. There will be resistance from your flesh, maybe friends, and most definitely from the enemy. But, also be encouraged! God is going to supernaturally help you and give you a great victory.
Get ready! The Holy Spirit will be speaking to you. The Word of God is going to come alive for you. You are going to be spiritually hungry like never before! 2013 is going to be the greatest year of your life.
