Do they literally mean zero intake of calories for 72 hours? That sounds like a long time. How do you prepare for that nutrition wise and mentally? People eat at night during the ramadan.

I suppose not, but the lack of specification which method of fasting was used is the most glaring omission in this piece.

Probably there is some minimum, because when you drink just regular water that has some calories as well. And not drinking for a day might be he worst dietary idea ever.

UPDATE: Water doesn't contain calories. Sorry for the misinformation.

My mouth (actually my hands) was faster then my brain. :-)

> When you starve, the system tries to save energy, and one of the things it can do to save energy is to recycle a lot of the immune cells that are not needed, especially those that may be damaged

That's remarkable news. I'm waiting to see the counter-arguments though. Fasting for 3 days seems like stretching the limits a bit. Also it seems to imply that these 3days periods are repeatable over the course of a few months.

If regular water has calories in it, then I would not be willing to drink it. ;)

Please explain where the calories in plain water come from.

Although I haven't attempted this myself, I have seen many people attempt to endure a 72 hours fast (as part of diagnosing a potential pheochromocytoma) and the majority experience this as extremely difficult.

I wonder if multiple shorter fasts — e.g., a 24 hours fast once a week — could be as beneficial.

Tim Ferriss has poked at the positive effects of intermittent fasting on cancer/health/longevity a bit. I found this interview with Dominic D'Agostino very informative: http://fourhourworkweek.com/2015/11/03/dominic-dagostino/
