Seems to have previously unknown benefits to the brain.
The problem with this article is that (a) they don’t really describe what the “fasting-style diet” is, in terms of how long the fast, or what days they do it, and (b), as with most nutrition studies, it’s probably based on self reporting, and it’s not clear that there are any controls.
I do suspect, though, that we didn’t evolved to three squares a day, which would have been hard as hunter gatherers, which is one of the ways that agriculture screwed up our health, though it allowed the existence of orders of magnitude more unhealthy people.
I personally fast almost every day until evening. Dinner (or supper, depending on your local vernacular) is my literal breakfast, though I don’t have bacon and eggs then.

Honey, I’m home! What’s for dinner?
Mammoth.
The original journal article is linked at the bottom of the page. The diet is described in the section headed “IER protocol.”
I once did an informal alternate day restriction protocol for several months with several total fasts for as many as three days. Like these subjects I rapidly lost fat and waist circumference, along with some muscle despite sustained moderate physical activity throughout the five working days every week.
To me eating a large meal in the morning or midday and no supper feels better than eating only in the evening.
