Just completed my spontaneous 72 hours no food fasting (only water) 🍽️❌ My longest autophagy experiment so far. Day 1 was the most unfamiliar. A bit hangry here and there. Day 2 my head got really clear and I could work well. The obvious part I didn't see coming: I train a lot, so there's always this calculation running about getting enough protein in. For three days it was just gone. That felt freeing. Whats your experiece with longer fast? What stuck with you afterwards and did you archive any specific goals?

@nebjamin Sure :) Blood pressure and glucose markers improve during multi day fasts in healthy people. Ketosis builds from day two, that's where the clearer head comes from. And autophagy, the cell recycling process that won the 2016 Nobel, gets triggered but it’s important to now distract your body with anything but water (and up to 5g salt per day) The anti aging claims you see everywhere aren't shown in humans though.
