Drink lots of water and do it for your spiritual reason , the mind is strong and you will be able to do it . i fast for 7 days during holly week, its not required by the Catholic church but its something i have been doing for 4 years now . the hardest days are the first 2 or 3 then your body gets use to it . when you are done fasting start eating small portions and slowly or else you might get sick . or get a stomach illness

fastling is not for 1+ days. That is unhealthy and ur spirit isnt worth death. When i fast for ramdhan (dont eat from sunrise to sunset) I just avoid food. Its easiest with school or work because u usually cant eat except for lunch breaks so its only avoiding food for like 30 minutes.
