Btw it's anything but a fad since most Orthodox Christians have been eating this way since 200 AD (basically it's what the Orthodox fasting and daily diet pattern prescribes and very religious Orthodox people observe, they don't do OMAD but basically it's classic 16/8 intermittent fasting and a 3 day fast ,with only water,every 2,5 months)
Many other eastern religions also follow some fasting pattern when it comes to eating.
