Same here.
I have often wanted to try fasting, mainly because Jesus says in Matthew 6:16-18 - When you fast, do not look sombre as the hypocrites do, for they disfigure their faces to show others they are fasting. I tell you the truth, they have received their reward in full. But when you fast, put oil on your head and wash your face, so that it will not be obvious to others that you are fasting, but only to your Father, who is unseen; and your Father, who sees what is done in secret, will reward you." (bold print mine)
So, he is not saying if you fast, he is saying when you fast, as if he expects us to do so. From all accounts, it is beneficial for us in terms of prayer and spiritual blessing. I've only ever tried fasting from caffeine and chocolate during Lent; would like to try other times, and more of a total fast (except water).
