4:42 "as monks and mediators, we only eat once in the morning." This seems quite plausibly an acquired wisdom, as opposed to a quirk of the practice. While I've not yet read much of the science myself, I've heard a great deal about the benefits of intermittent fasting. Moreover, there's interesting research suggesting that making breakfast your biggest meal provides benefits. I would not be at all surprised if eating only once in the morning is the optimal approach.
