I did 35 days on electrolytes/vitamins-only. The first two days were annoying, then it was a smooth sailing for a week (did two bike climbs at the end of the week) and then gradual decrease of physical energy/abilities while mental energy stayed constant. At around three weeks some feelings of euphoria arrived, then a week later the opposites. I was thinking whether to continue or not, but I reached my target weight (losing 1lb/day) and my weight loss slowed to less than 0.5lb/day so I called it quits. Refeeding was kicked off with a high-dose thiamine and some glucose to avoid refeeding syndrome, then I spent a week on bone broth, slowly adding more stuff in. A few months later covid arrived, I got it and am not sure if the fast helped surviving it or actually worsened it as while I had almost asymptomatic run, in a few months it morphed into long covid. I think I depleted my B vitamins during the long fast and kicked off mitochondrial dysfunction as a consequence of covid.
