I too have (accidentally) consumed less than 800 calories in a day (got caught up in something and lost track of time). I felt noticeably worse.
Does anyone know if/how much people can get used to such a diet? For people that fasted regularly (more than one day), is it always like that, or do you sort of get used to it? Being distracted by being hungry is a pretty big downside for me since I spend a lot of time programming, and distractions make me considerably less productive.
The feeling of hunger never disappeared, but it got easier to accept.
Some days that were really busy at work flew by without a problem at all. It was easier for me when I was engaged in a task that demanded most of my concentration.
One day is not enough time to adapt to a major dietary modification. I’d suggest giving any change at least a week or two, but preferably a month, before deciding if you can tolerate it or not.
And try out CR and IF independently, don’t jump into both at the same time.
ETA: If you go more than a week on IF and you still feel terrible, you (like most people, sadly) have larger metabolic issues to resolve first. So switching to a Weston A. Price traditional/paleo-ish or Perfect Health Diet setup, getting your health up a few levels, and then trying IF after that.
Anecdotally, I found it fairly easy when younger to do an IF diet. The first few times fasting for a day, the waves of craving/hunger could be fairly bad, and fasting for a second or third day was pushing it much too far, but overall it wasn’t so bad. And it was fun eating double on the non-fasting days.
I fast once a month (sometimes more), generally the first sunday of the month. One does get used to doing that.
I have also fasted for a week at a time, being one small meal each day. It isn’t so bad especially if one is used to fasting for a day time period previously.
