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.

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.
