This is the breakfast that increases satiety and improves concentration

The statement “breakfast is the most important meal of the day” is a well-worn cliché that never had much of a scientific basis, but a new Danish study explored how different types of breakfast affect satiety and concentration and put a new spin on the old one. topical.

According to researchers published in the Journal of Dairy Science, a protein-rich breakfast can increase satiety and improve concentration. The study followed 30 obese women between the ages of 18 and 30 for three days, during which they consumed a high-protein breakfast, a high-carbohydrate breakfast, or no breakfast.

The women’s feelings of satiety, hormone levels and energy intake were measured at mealtime. Their total daily energy intake was also measured. Participants also had to complete a cognitive concentration test during the study.

“We found that a high-protein breakfast with skyr (a sour milk-based product) and oats increased participants’ satiety and concentration, but did not reduce overall energy intake compared to skipping breakfast or eating a rich breakfast. in carbohydrates,” says Mette Hansen, associate professor at Aarhus University, doctor at the Department of Public Health and one of the authors of the study.

The number of overweight people is increasing around the world. Obesity is often accompanied by lifestyle diseases, such as type 2 diabetes. Previous studies have shown that people who eat breakfast have a lower BMI than those who do not eat breakfast, and in general it was found that foods rich in Proteins have a greater satiating effect compared to carbohydrate-rich and fat-rich foods with the same calorie content.

The aim was, therefore, to check whether a protein-rich breakfast could be a good strategy to achieve greater satiety during the day and thus reduce daily calorie intake. However, the solution is not so simple, according to Mette Hansen.

“The results confirm that protein-rich meals increase the feeling of satiety, which is positive for preventing weight gain. However, the results also suggest that, for this nutritional strategy to be effective, it is not enough to have a protein-rich breakfast,” he says.

The potential of replacing a diet rich in carbohydrates with one rich in protein is clearly seen in the satiating effects measured in the study. Several of the subjects had difficulty consuming the entire protein-rich breakfast of skyr and oats.

The satiating effect of two different foods

“It is intriguing that there can be such a big difference in the satiating effect of two different foods with the same calorie content. If the women in the project had been able to choose the size of the meal themselves, it is likely that they would have consumed more food and therefore more calories on the day they were served bread and jam than on the day they were given skyr and oats,” explains Mette Hansen.

According to the researcher, although the study provided important data, it also has its limitations because only young, overweight women participated in it. The research is also based on relatively short-term observations, leaving open the question of how long-term dietary changes may affect health and weight.

Therefore, Mette Hansen points out that the study highlights the need for further research to understand how different types of foods affect health over time. “We already have new data from a trial in which participants received either a high-protein breakfast or a low-protein breakfast,” she says.

The objective was to study how different types of breakfast affect body composition and other parameters such as microbiota and cholesterol levels,” concludes Hansen, who indicates that the results of these studies can lead to the development of more specific nutritional recommendations. in the future.
