I would say you can give up a meal, sweets,tv show or something of sacrafice to you for God. You must during the time of fast
pray and read your Bible. Some also do a juce fast with real fruit juices. Whatever you do as sacrafice to God he
will bless you efforts. It is not about food but sacrafice to God and hearing from Him through prayer and His word. The Daniel fast of fruits and vegtables is another one. Their are several recorded in the Bible read the info I gave and do some research on fasting and praying. I will post some details I have on the different types of fasting. But please join us in praying and loving God as unit. There is more power we it is a group.
