Fasting is interesting.
When someone fasts for lent...giving up chocolate or something specific.that they like for 30 days that is one aspect.
When someone fasts during Ramadan, they feast after the sun sets everyday.
When someone is on a dietary fast, food, or a particular food is eliminated for days...no breaks...
Me? I fast from the time I fall asleep...everyday...once a day...till I break the fast...at breakfast. And then I fast again...till lunch, lol.
Fasts are what you make of them...and looking down your nose in session at what others do or call fasting...that speaks more about you than them.
