Fasting and duration seems to be an individual discovery, until more scientific data measurements about amino acids, genetics, immune state, glycogen levels, etc are established. I've water fasted over 50 times in the 15 months ranging from 16 - 48 hours to help with Lyme and other tick borne pathogens. I've found it to be highly anti-inflammatory and have yet to feel bad (maybe 3 very mild headaches). For example, my vision acuity improves around 15 hours into a fast every time (noticeable when reading). I've even jogged or walked miles 30 hours into a fast, depending on residual glycogen levels in the blood and muscles. The glycogen should be consumed from the liver, blood, and muscles (partial) before entering ketosis. With that said, it's not for everyone and it is probably better to slowly increase the duration of the water fast to evaluate individual response. Also, hundreds of millions in the Muslim culture practice a complete daylight fast every year with minimal side effect. That should be significantly significant ;-).
