What are some major effects of short term fasting?

no professional stuff but i have fasted dozens of times in my life. if its your first time you will get very hungry, later on in the day becoming weak, tired and maybe a little dizzy. this could be helped by the fact that you can drink, for when i fast i do not. good luck and if u have to just lay down for a while and watch tv, makes the time go by faster. ull feel fulfilled when its over.
