However, something did catch my eye. I've never read about intermittent fasting except little bits here occasionally. So this may be old news to people more familiar with it.
Bold italics mine.“Our earliest antecedents,†Dr. Mosley argued, “lived a feast-or-famine existence, gorging themselves after a big hunt and then not eating until they scored the next one.†Similarly, he explained, temporary fasting is a ritual of religions like Islam and Judaism — as demonstrated by Ramadan and Yom Kippur. “We shouldn’t have a fear of hunger if it is just temporary,†he said.
If one or two days weekly is just temporary hunger, then a few hours between meals is nothing --even between dinner and breakfast. Hunger isn't an emergency. Or, as Karen Le Billon wrote in French Kids Eat Everything, it's okay to feel hunger (as in between meals) but not okay to be hungry (as in never having enough food).
It's speculated that part of the reason the Greeks, who have traditionally been so healthy, is not only due to what they eat, but also how they eat. The Greek Orthodox religion has about 180 days of fasting each year. Some days just eliminate meat, others are more restrictive, even including abstinence from olive oil. Every Wednesday and Friday are fasting days.
