>Intermittent fasting has a nice advantage - nobody can make any money off of it.
I think the Abrahamic religions figured it out already...you create holy days like Yom Kippur, Lent, Ramadan and make fasting a mainstay of the traditions. Boom, not only can you make money on not eating, but you can simultaneously take credit for all the actual benefits of the fast itself.
I would disagree here. You're assuming that Abrahamic religion solely integrated fasting for credit purposes. Whatever you think of religion, you can at least give them a point on that.
