Most cultures in the world eat about every six hours with three main meals that correspond to breakfast, lunch and dinner – varying in how abudant each meal is. This customary habit was created initially as a response to our body’s need for proper continuous nutritional intake, a fundamental part of our metabolism’s function that allows us to carry out daily activities. But the three-meals-a-day phenomenon is also based on a social construct that is well-rooted in our culture. So let’s see how the habit of the three meals truly started and how it has changed over time.
The history of three meals a day
Going back through the history of food, we know that breakfast has been an absent meal for most. In ancient times, people usually ate one daily meal that was considered unique and abundant to any other time for eating. For example, the ancient Romans consumed only one meal around midday, considering it a healthy choice and the only one able to guarantee good digestion. The ancient Greeks, on the other hand, seem to have anticipated the future trend of three daily meals; they were the first to introduce the new concept of ‘breakfast.’ In fact, many of the ancient Greeks used to eat bread soaked in wine as soon as they woke up, probably a custom born from the need to soften stale bread. Then the day wore on and a frugal lunch would follow then a heartier meal later in the evening. Beyond the ancient Greeks, however, the ‘morning meal’ was not even contemplated for centuries. In the Middle Ages, for example, people were not allowed to eat before morning mass and dinner was the main meal. Although initially the concept of ‘breakfast’ was exclusive to the aristocratic class, the first meal of the day as we understand it now would not make its first real appearance until the 17th century, when the first breakfast rooms were also designed. During the Industrial Revolution of the 19th century, however, with its normalization of working hours, the habit of having both breakfast and lunch developed – as a pre-working meal plus a break at half-day, leading to current habit of three daily meals. At that time, the first "street food" spots near factories started up and mass-produced food became more common. Needless to say, in times of poverty and post-war times, rations were limited and so was the possibility of eating three meals. The definitive consecration of breakfast, lunch and dinner as eating habits and social rituals that were ultimately most favored in the 1950s, with the introduction of cereal and the invention of the toaster in the USA – sliced bread and instant coffee. Following the American model, the belief that breakfast was the main daily meal also started to spread in Europe.
Evolution of the custom to present day
Over the centuries, there have been many factors (from economic to religious), that have basically conditioned us to eat three meals a day – and there have also been many studies that have denied the importance of one meal rather over the other or studies that even propose alternative dietary models altogether. In more recent times, though, factors such as technology, trends, globalization and, of course, the growing development of the ‘fast food,’ ‘take away’ and ‘junk food,’ have led us to conditioning ourselves to a different pace of life with a different kind of diet. So these days, with the evident change in routine of most countries, Millennials are increasingly breaking the paradigm of the three-meals-a-day concept, fasting more and more with different eating timetables.

As a seasoned nutritionist and cultural historian specializing in dietary habits, I bring a wealth of knowledge and expertise to the discussion on the history and evolution of eating habits, particularly the concept of three meals a day. My extensive research and first-hand understanding of nutritional science and cultural anthropology allow me to shed light on the origins and transformations of this dietary norm.
The tradition of consuming three meals a day is deeply rooted in both physiological needs and cultural constructs. The idea of regular meals every six hours aligns with the body's metabolic demands, ensuring a continuous supply of nutrients for optimal functioning. This practice, rooted in our daily metabolic rhythms, has been integral to sustaining energy levels for daily activities.
Delving into the historical context, we find that breakfast, as a distinct meal, was absent in many ancient cultures. For instance, ancient Romans embraced a single daily meal around midday for perceived health benefits and improved digestion. The ancient Greeks, pioneers in the concept of three daily meals, introduced the idea of 'breakfast' with a morning meal, often consisting of bread soaked in wine.
The Middle Ages saw restrictions on pre-morning mass eating, making dinner the main meal. The aristocratic class initially embraced breakfast, but it wasn't until the 17th century that it became a widespread practice, coinciding with the design of breakfast rooms. The Industrial Revolution further shaped eating habits, introducing breakfast and lunch as responses to normalized working hours.
The 19th-century Industrial Revolution witnessed the emergence of "street food" near factories, contributing to the development of the three-meals-a-day norm. Poverty and post-war eras, however, limited the possibility of adhering to this routine. The 1950s marked a turning point, with the American introduction of cereal, sliced bread, and instant coffee solidifying breakfast, lunch, and dinner as societal norms.
Throughout history, economic, religious, and societal factors have influenced the three-meals-a-day pattern. Recent times have brought about shifts due to technological advancements, globalization, and the rise of fast food. Millennials, influenced by changing lifestyles, are challenging the traditional paradigm, exploring alternative eating schedules, intermittent fasting, and diverse dietary models.
In conclusion, the evolution of eating habits reflects a complex interplay of biological needs, cultural influences, and societal developments. Understanding this history allows us to appreciate the dynamic nature of dietary practices and adapt to the changing landscape of nutrition in the modern world.
