It doesn’t have to be just fasting from food, it can be from anything that you really want to do. Many people choose different things to fast from. Some from food, others watching TV, some Internet, others hobbies.
No matter what you chose to fast from, so long as you mean the sacrifice of time you’re giving, its a really invigorating experience.
Fasting is about sacrifice, it could be anything that you REALLY want to do, but you rather use the time to be with God.
Fasting is feeding the spirit and it helps you humble yourself. You can do it any day.
Jesus has given us fasting to cleanse our souls from attachments to things of this world. Also in reparation for our sins. It’s a wonderful thing.
We are human and fallen, that is a fact. And we all should be working on being holy.
Jesus has told us to fast, check this out from the Sermon on the Mount, where Jesus says:
“And when you fast, do not look dismal, like the hypocrites, for they disfigure their faces that their fasting may be seen by men. Truly, I say to you, they have received their reward. But when you fast, anoint your head and wash your face, so that you do not appear to men to be fasting, but to your Father who is in the secret place; and your Father who sees in secret will reward you openly.”
