How long can you fast?

I fast mostly on Sundays. I always fast 6 to 6

I've never really considered it fasting, I'm just not hungry. Most days I don't eat breakfast and rarely do I eat lunch. I may snack for lunch but mostly it's just a few snacks during the day and dinner. I got in that habit when I worked retail and never really changed. Plus with everything we do and have planned during the day I have to be reminded to eat.

I have to take one of my medications with food, so I don’t think I have ever fast for long. That doesn’t mean I have to eat a lot with the medication; half an orange is enough to keep from getting an ulcer. So the longest I’ve ever gone was probably 12 hours.

I usually don't eat breakfast as I wake up late at around 10am. I have brunch instead.

I have tried intermittent fasting before. eating my "dinner" at 3 pm and my "breakfast" at 9 am. that's 18 hours of no food just water or green tea without honey or sugar.

8 hours max That's about it Any longer I will die

My record was 30 hours. I had my dinner at 6pm the day before and the next day, I busy travelling to various locations and completing various tasks. By the time I settle down for a meal, it was already 12 midnight. I was not feeling hungry till about 11pm.
