Ctrl-f also returns no results for Lent. I haven't tried for other religious fasting or abstinent holidays but I'm sure there would be 0 to few mentions. HN skews strongly towards certain industries and demographics so it's a bad sample of "the western world" and it seems that most people posting here would simply lump Ramadan under "religious practices" of which there are several mentions. Most religions include both feasting and fasting practices so I wouldn't single out any single one as more healthy or hurtful for the world.

I agree with the basic premise that religious fasting is an often overlooked but beneficial practice in the modern era.
