My aim is to do a 3 day fast, 4 times per year, so once per quarter/once every 3 months. I didn't quite make it to 3 full days in my first attempt, but I'm happy with how far I made it for this one; 62 hours and 42 minutes. I'll endeavour to do better next time. During my fasting days, I still drink black coffee with MCT oil added, lots of water obviously, I have an essential amino acid (EAA) drink once per day, and a cup of beef bone broth once per day too. The first things I ate when I broke my fast were a green apple, followed by a couple of handfuls of salted macadamias, and within about 10 minutes, I had what felt like 10 times the mental clarity and physical energy, I felt awesome.
