British people - and many others across the world - have been brought up on the idea of three square meals a day as a normal eating pattern, but it wasn't always that way.
People are repeatedly told the hallowed family dinner around a table is in decline and the UK is not the only country experiencing such change.
The case for breakfast, missed by many with deleterious effects, is that it makes us more alert, helps keep us trim and improves children's work and behaviour at school.
But when people worry that breaking with the traditional three meals a day is harmful, are they right about the traditional part? Have people always eaten in that pattern?
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".
Religious ritual also gave us the full English breakfast. On Collop Monday, the day before Shrove Tuesday, people had to use up meat before the start of Lent. Much of that meat was pork and bacon as pigs were kept by many people. The meat was often eaten with eggs, which also had to be used up, and the precursor of the full English breakfast was born.
But at the time it probably wasn't eaten in the morning.
In about the 17th Century it is believed that all social classes started eating breakfast, according to chef Clarissa Dickson Wright. After the restoration of Charles II, coffee, tea and dishes like scrambled eggs started to appear on the tables of the wealthy. By the late 1740s, breakfast rooms also started appearing in the homes of the rich.
This morning meal reached new levels of decadence in aristocratic circles in the 19th Century, with the fashion for hunting parties that lasted days, even weeks. Up to 24 dishes would be served for breakfast.
The Industrial Revolution in the mid-19th Century regularised working hours, with labourers needing an early meal to sustain them at work. All classes started to eat a meal before going to work, even the bosses.
At the turn of the 20th Century, breakfast was revolutionised once again by American John Harvey Kellogg. He accidentally left some boiled maize out and it went stale. He passed it through some rollers and baked it, creating the world's first cornflake. He sparked a multi-billion pound industry.
By the 1920s and 1930s the government was promoting breakfast as the most important meal of the day, but then World War II made the usual breakfast fare hard to get. But as Britain emerged from the post-war years into the economically liberated 1950s, things like American toasters, sliced bread, instant coffee and pre-sugared cereals invaded the home. Breakfast as we now know it.
It's the Earl of Sandwich's famous late-night snack from the 1750s that has come to dominate the modern lunchtime menu. One evening he ordered his valet to bring him cold meats between some bread. He could eat the snack with just one hand and wouldn't get grease on anything.
Today the average time taken to eat lunch - usually in front of the computer - is roughly 15 minutes, according to researchers at the University of Westminster. The original meaning of lunch or "nuncheon" as a small, quick snack between proper meals is just as apt now as it ever was.
