i'm too lazy to read all the papers on this subject, so indulge me: Do any measure brain "output"? i bet earlier humans would eat a lot, then walk for miles until finding another spot, or stuff them on seals and then sleep on some warm cave and do nothing until the hunger was bad enough to justify another hunt on the cold outside, etc. I doubt you can live that way with a 9-5 job.

I did a 15 days total fast (ie no food, only water) last year. As far as I can tell my brain output remained the same, I could function plainly as a dev. I was not 100% physically (say 80%), but nothing major (I'm not practicing any sport though).

  This is fascinating to me. How much wait did you lose? Did your hunger stay at approximately the same level? Did eating destroy your system after your fast?

    After 2 or 3 days, I wasn't hungry anymore, it was just my brain that wanted the comfort of eating especially when I was bored. But if you manage to get over the first days, the willpower needed to go on until the end is not that great. Physically I could have done at least 15 more days but I would have needed to have a busy life. When idle my brain was tricking me, I ended watching a lot of cooking videos on Youtube, preparing all the good meals I would do once I restarted to eat. I felt weak in the morning, but once I started to drink about one liter (about a quart) of water after waking up it disappeared. I lost 11.8kg (about 26 pounds) but of course I regained everything once I stopped the fasting. I didn't fast for weight loss (though I wouldn't have minded if the loss was permanent, I'm clearly overweight) but for the supposed global health benefits. Honestly I didn't see much change, it was a bit disappointing. Before this long fast I was fasting every Monday and had done a successful 3 days fast. However since then, I wasn't able to fast even one day a bit like my willpower is gone.
