AS a religious practice I would fast one day a week from sunset to sunset.
(Ancient day was from sunset to sunset) But mainly that was an easy thing to do. I only drank water. I would also do some three or four day and I am mad at myself for not practicing fasting more often. I could think so much better and was a great form of self-discipline.
Most modern Christians have a wacky idea of fasting. Most do not go water only. Several will drink liquid juices and other liquid foods. No idea why???? Or there is the weird modern invention called the "Daniel Fast" which equals eating Kosher in the Bible but in practice it is eating like a vegetarian for a few days or weeks. No idea how this happened.
