About 30 hours.

I had to go nil-by-mouth for 12 hours before an operation to repair a fairly serious injury and they kept pushing the surgery back and back and back. Higher priority cases were keeping the surgeon. It wasn’t like I was low priority either, but my injury was stable and not immediately life threatening.

Did I mention I’d also lost blood? That made for a force multiplier.

In the end, they admitted defeat - the surgeon had worked too long anyway - let me eat something and rescheduled my surgery for the following day.

Let me tell you, that was the best chicken I ever ate.

Roughly 3 days as well. The shakes were crazy since I was drinking coffee and abusing amphetamine like mad as well.

About three days. I get headaches, and shakey, and at some point in the first twenty four hours the hunger pangs vanish. So if I focused through something without eatung I might only realize due to headache and the empty vibrating feel.

It happens less as I get older as I understand body signals better and eat before the point when the hunger pangs fade.

Something like 36 hours without food, and around 12 hours without water in prep for surgery. I was delirious the last several hours.

8 day fast. Water only. I was living and eating horribly at the time. I needed a drastic reset and it worked very well.

A couple of days, I was doing Atkins diet at the time and completely lost my hunger, so I just forgot to eat for two days until someone asked me what I had had for lunch and I realized I hadn’t eaten lunch, or dinner, or lunch the day before, or dinner the day before that. It was a weird feeling realizing I had gone almost 48 hours without food without even noticing.

Probably around 72 hours. I had a severe bout of depression a decade ago. I’m not certain how long I went without food because my memory of that period is hazy, but I barely ate or left my bed for a week. A few years before that I had salmonella poisoning (do NOT recommend) and didn’t eat or really even sleep for something like 10 days. I drank sugar water and electrolytes to stay alive but I still lost about 10 kilos.

I accidentally intermittent fast all the time, adhd brain along with weird lunch pattern at work. I think at this point, I should just say I do it to sound cool.

Covid had be bedridden for about 3 days and feeling too sick to eat, and living on my own I had nobody to help me.

Two and a half day for a fast. I don’t count being ill, like a flu

probably like 18 hours max

Did a 3 day fast once.

It was actually amazing. The last 8 hours were where it got rough, but from hours 12 to 66, I basically wasn’t even hungry because my body entered ketosis. Did full keto for a month afterwards because I was already there. Dropped 15lbs and felt like a golden god for months afterwards. I’ve done some 36-48 hour fasts since then, but even 48 hours isn’t the same thing.

From a Sunday lunch through dinner Wednesday evening.

Not a purposeful fast, I just had a huge hours-long meal of endless samples of steak, lamb, and chicken at a Brazilian Steakhouse. Also several large salads, and a small dessert.

So anyway, I just wasn’t hungry for days after that. I didn’t have any constipation, no drop in energy, so I went about my business as usual, but without eating for a few days.

Something like 65 hours. I used to routinely do 3 day fasts when I was working out a lot. But routinely like every 3 to 6 months. They are very hard to sleep and be functioning on.

A week for medical reasons, but I was being given intravenous water and nutrients the whole time. Those don’t stop you from feeling like your stomach is empty, unfortunately. The first slice of toast afterwards was possibly the best thing I have ever eaten

Out of choice, maybe 32-ish hours? A full day plus sleep the night beforehand
