That's sort of the rub in cavalierly recommending things to the general population, even when they're only somewhat extreme. There are plenty of undiagnosed conditions out there, and the further you move from the center of the distribution, the more you're going to sweep up potential risk in ways that aren't easily caught with a simple "not applicable if".

I say this as someone who fasts pretty often, though usually not more than 2 days. It's the same reason I wouldn't recommend everyone go out and take 200 mcg of LSD, "unless you have a mental health condition". This world of perfect information about one's own health that you're imagining simply doesn't exist. (Again, I say this as someone who thinks LSD is wonderful and salutary and has recommended it to many many friends in person with the appropriate personalized caveats).
