For decades, breakfast has been presented as the pillar of a successful day. This idea, often taught from childhood, is based on an affirmation: “Breakfast is the most important meal of the day”. But what do scientific studies really say about it, and why has this notion become so established in our habits?
A belief rooted in history and marketing
The origin of this idea goes back at the end of the 19th centurywhen influential figures like John Harvey Kelloggpioneer of industrial cereals, promoted the importance of breakfast for reasons both medical and commercial. This discourse, amplified in the 20th century, has benefited from sustained marketing campaigns, often financed by the agri-food industry. The objective? Encourage cereal consumption ready to eat and other products intended for this meal.
What modern studies say
A study published in 2019 in the “BMJ” (British Medical Journal) questions the universality of this statement. After analyzing several studies on the impact of breakfast, the authors concluded that, contrary to popular belief, skipping this meal does not automatically cause weight gain. On the contrary, people who skip breakfast sometimes consume fewer calories throughout the day.
However, these findings do not mean that breakfast is useless or harmful. Its importance depends largely lifestyle, energy needs, and eating habits of each person. For example, athletes, growing children, or people with physical jobs can benefit from a nutrient-rich breakfast to maintain their energy and focus throughout the day.
The impact of breakfast on well-being
Beyond nutrition, the study shows correlations between eating a balanced breakfast and better mental health, particularly among young people. According to some research, children and adolescents who take one are perform better at school and display better life satisfaction. These positive effects could be explained by blood glucose regulationcrucial for the brain, and the social role of the morning family meal.
-Although breakfast can be beneficial, it is important to qualify the general recommendations. Many works extolling its merits have been funded by those in the food industry, which can bias the conclusions. Moreover, a balanced dietadapted to its specific needs, remains more essential than the time at which the calories are consumed.
An individual choice above all
Ultimately, there is no universal rule. Some find their balance by taking a hearty breakfast, while others feel better as they start their day without eating. The main thing is to pay attention to your body’s signals, choose nutritious foods and avoid processed products, whether in the morning or at another time of the day.
So, if the idea of “most important meal” persists, it must be placed in a personal context, far from universal slogans. It’s up to everyone to redefine their food priorities according to their lifestyle and needs.
