Protein distribution throughout the day

Proteins are a component whose quantity is usually monitored first when assessing the quality of a diet. In practice, it turns out that despite the crucial role they play in metabolism, most of the population manages them poorly in their diet.

Monitoring the amount of proteins in the diet is important for several reasons:

• for the child population, it is necessary to manage rapid growth,
• athletes aim to support muscle metabolism,
• women after menopause and men after andropause need a slightly higher intake due to the prevention of bone density reduction,
• the general population should control their adequate intake mainly to prevent catabolic processes.

Setting their optimal amount in the daily diet is not difficult at all; it is typically recommended to be 15-20% of the total energy intake.

A common phenomenon in Western society is their excess, which unnecessarily burdens the metabolism and partially supports fat storage. The most common mistake, however, is their distribution throughout the day. Most people tend to consume a low-protein breakfast, increase the proportion of proteins at lunch, and generously have an even larger portion for dinner. It turns out that even in situations where the total daily protein intake corresponds to the recommended standard, having a varied distribution in meals has a much worse impact on supporting muscle metabolism than having them evenly distributed throughout the day.

The difference is truly significant. Research conducted by American scientists found that if each main meal throughout the day contains approximately the same amount of proteins, muscle protein synthesis increases by 25% compared to a situation where breakfast is low in protein and dinner is rich in protein. [1] This information holds considerable value for many people, and its potential can be exploited not only by athletes seeking to enhance physical performance and support recovery processes.

Implementing such a change is not difficult at all. It simply requires an effort to control the amount of protein-rich foods in individual meals. If a person is used to light breakfasts with a very low protein content, they should start exploring ways to enrich their protein balance with different foods.

Conversely, for dinners that contain unnecessarily high amounts of proteins, it is necessary to consider to what extent the quantity of their concentrated source, which is most often meat, should be reduced.
