I have been reading about the ancient civilisations who understood the importance of not over-eating, especially at breakfast.
"At the period of their greatest power, the Greeks and Romans ate only one meal a day."
For example, here are some good quotes from the book entitled “The Hygienic System: Orthotrophy” by Dr Herbert M. Shelton, originally published in 1935: Dr. Felix Oswald says that “during the zenith period of Grecian and Roman civilization monogamy was not as firmly established as the rule that a health-loving man should content himself with one meal a day, and never eat till he had leisure to digest, i.e., not till the day’s work was wholly done.
For more than a thousand years the one meal plan was the established rule among the civilized nations inhabiting the coast-lands of the Mediterranean.
The evening repast–call it supper or dinner–was a kind of domestic festival, the reward of the day’s toil, an enjoyment which rich and poor refrained from marring by premature gratifications of their appetites.”
Breakfast as we know it didn’t exist for large parts of history. The Romans didn’t really eat it, usually consuming only one meal a day around noon, says food historian Caroline Yeldham. In fact, breakfast was actively frowned upon.
“The Romans believed it was healthier to eat only one meal a day,” she says. “They were obsessed with digestion and eating more than one meal was considered a form of gluttony. This thinking impacted on the way people ate for a very long time.”
In the Middle Ages monastic life largely shaped when people ate, says food historian Ivan Day. Nothing could be eaten before morning Mass and meat could only be eaten for half the days of the year. It's thought the word breakfast entered the English language during this time and literally meant "break the night's fast".
So, if breakfast literally means breaking our overnight fast. Wouldn't we want to continue fasting in order to reap the additional benefits of daily intermittent fasting? It is surely easier to continue fasting for a few extra hours - say until 10.30 am or perhaps longer until we genuinely feel hungry. The whole idea of eating breakfast is deeply entrenched but is still an invented cultural concept and is not a given. So although it is considered healthy and essential, breakfast was not always considered desirable and it is not a prima facie paradigm of healthy eating.
Skipping or delaying your breakfast until mid morning might be a useful tool to try a few times. Give it a go and see if it works for you!
