on the day to day I regularly do 12h during the day without food (almost every work day)

I've done a few 2 and 3 day fasts for various reasons

I've done 3 or so day stints when sick with rotavirus and when I fucked up my shoulder and waiting for surgery

All in all going with out food for 3 days is not too hard

I’ve gone three weeks and change without a single calorie of food. Not by choice - medical thing. Lost about 30 lbs give or take. Was hard to start eating again once I did. Lost additional weight beyond the 30. Went from fat to skinny. Took years to eat properly again. Now I’m fat again :)

Was interesting for many reasons.

1. it’s possible if you’re injured to not be hungry and starve to death without feeling any hunger whatsoever
2. while I lost fat, I lost more muscle. Crazy how the body canibalizes itself.
3. still need water, that you can’t go without. But you can go a long time without food. I could have easily gone weeks longer I think without food.
4. Hug your family and always tell them you love them. I lived through my ordeal and gained perspective, but many young people die without saying and doing the things they should.

I fasted about 48 hours to experience a semi ascetic acid trip. Was a good time; had some incredible break throughs. Dived into a pool, and it felt like I was diving into a kaleidoscope of colors. Can't recommend anyone experience it that way, nor would I say I'd do it that way again, but taking your mind and body through moderated extremes can be pretty profound; assuming you have people around you to make sure you're not doing anything particularly stupid to hurt yourself or others.

I’ve fasted for a couple days when depressed and it was fine.

What I can never compare anything to is suffering food insecurity. When I was a kid the union my father was a part of went on strike. My mom didn’t work. I was in kindergarten, and I was starving all the time. Some days it was just flintstone vitamins and juicy juice. Sometimes just a pack of snack crackers. I remember being so excited to get those. Once I was so hungry I climbed the cabinets and was gnawing on dried out brown sugar because it was the only thing I could find. That earned another flintstone. I received a few granola bars from my teachers.

For a long time I used to go into any new house and explore the kitchen and make sure there was food. Also, I end up feeding all my hungry kids now. Costco saves me there.

I've done just shy of 2 weeks without food. I've never gone more than like 10 hours without water though, at least not while awake.

Fasting is fine. "Hunger" is usually anticipation of food. Once you push past the initial feeling it simply goes away.

Not drinking water sucks. Everything feels awful after a day without water.

84 hours without food (that's 3 full days plus the extra night after). Didn't feel too bad since after 24 hours my body gave up asking for food so I felt kind of lethargic but not hungry. I did it as a kind of personal challenge, probably ill-advised, but it wasn't too bad for me. I still drank plenty of water throughout that time. I wasn't even that hungry when I broke the fast, I just had a light salad, then I felt really hungry in the hours afterwards..

Around a day and a half without any source of food, limited water and building my own shelter in the middle of nowhere. Would not recommend on the thirst and hunger side, but it was quite peaceful. I ended up eating a little bit of my flavoured chapstick, I was quite hungry and thirsty. Thankfully weather was mild so no heat or cold related issues shelter wise. I've been camping in tents when it's gotten so cold that frost formed inside the tent, that's not fun either. Once I made it back to civilisation, I had a long shower, drank lots of water, and ate two full plates of food. Almost threw up afterwards from overeating.

Had ulcerative colitis. Went about a month on Gatorade and clear vegetable broth. Another month or two on TPN after surgery with very little to no veggie broth.

Went from 175 to 115. 0/10 would not recommend.

Went two days without food. It was pretty horrible and I slept more to cope.

I had terrible stomach cramps one night. I was so sore that I didn't eat after that for 4 days. It's actually way easier than I would have thought, no real consequences.

Never really been without water, but I've avoided eating for ~3 days due to illness a couple times. It's kinda easy when there's a reason for it (nausea, mostly) - when you know the alternative is worse, short-term hunger is only mildly annoying.

Five days without food. I had a bout of gastritus (damage to the stomach lining) and never once felt hungry during that time. I was going about my normal routine and felt completely normal otherwise. Kinda surprised by that.

There was a period where I would fast every thursday into friday, 24 hours, but I allowed myself water. No real issues. Less impactful than a single beer or smoking some pot.

That being said I have huge respect for those keeping Ramadan.

Did a week as a challenge/experience. I read up a bit beforehand and just made sure I got enough water and electrolytes. Was getting hungry during the first day and more during the second, but then it just kinda stopped. I felt tired and weak a bit but apart from that everything fine.

Two days without solid food because my stomach is stupid. I was hydrated the entire time though and drinking ginger ale occasionally.

Without food, I think 2.5 days (somewhere around 2.5 days). Wasn't bad, although I sometimes get dizzy when standing and it exacerbated to the point I was worried I might actually pass out (but I didn't; just felt like a had a very low-grade fever for a couple minutes after?)

Without food, just shy of 24 hours. Slept around 12 hours after almost pulling an all-nighter, then never got hungry enough to get out of my room until late in the night. Was groggy all day, didn't feel hungry for several hours, then it nagged for another few hours until it gnawed at me and I couldn't do anything without thinking about food. So I ate, surprisingly only took a normal-sized meal to satisfy the hunger.

I've gone without water or food for about 9 hours at a time on several occasions. Mostly just makes me lethargic at the end. But the most memorable time was when I went on a trail with a couple friends for about 4 hours. It was the middle of summer in an arid climate and I realized I forgot to bring water about an hour in. Was very parched and heart racing by the end, but didn't bother me too much. Then chugged about 3x 500 mL bottles as soon as I got back in the car.
