I can fast 36 hours no problem (evening day 1 to morning day 3). I do this once a week and Keto omad/tmad on other days. However I want to do an extended fast each month, partly because I have a lot more fat to lose and partly because I want autophagy. I only have water, salt and black coffee.
I’ve been surprised at how non-hungry I am, even when others near me are gorging. However after 3-4 days I am desperate to TASTE something - it’s like my mouth is bored of having no flavours in it. So, not hungry, but some weird sort of oral boredom is leading me to break fasts. Possibly the more I do the better I’ll get. But if anyone has ideas to avoid this feeling I’d welcome it!
