Table 1.
Anthropometric measurements of study participants, reported as mean +/- standard deviation.
Using a Wilcoxon-Mann–Whitney test we found no significantly difference for any variable in terms of gender.
Fig 1.
Boxplot shows the intake values including number of participants for each case (above the box), and median values (inside it).
Both nutrients categories are significantly different (Lipid: t = 3.30, p < 0.001; Protein t = 8.065, p < 0.001).

Basic flow diagram for data analysis.
Table 2.
Values above gray boxes correspond to mean and standard deviation for each nutrient intake condition; Gray boxes shows U Mann-Whitney test.
Fig 3.
We show a resting-state EEG Mutual Information networks (MI), considering five regions of interest (ROIs): Front left, front right; posterior left, posterior right; and midline.
MI was obtained for each broad brain band in the two resting-state conditions, Open and Closed eyes. Similar to what is occurring in a correlation analysis, the red color indicates positive relationship between ROIs and blue negative. The thickness of the line represents the intensity of the relationship.
Fig 4.
Minimum spanning tree (MST) of absolute brain power networks for protein or lipid intake level in both condition A) closed or B) Open eyes.
Weight of the MST represents a measure of total structural and functional network connectivity (the higher the value, the higher connectivity). The complementary right-side subpanel (one for protein intake and one for lipid intake) shows the difference percentage for the condition, each value is annotated inside the corresponding bar of the sub-panel (light blue is used for positive difference, dark blue for negative difference).
Fig 5.
Results from Random Forest of Mean Decrease Gini values that tell us the relative importance of different ASVs to the classification processes into low Vs high intake for both protein (gray) and lipid (black) intake.
Fig 6.
Weight of the Minimum Spanning Tree (MST) as a measure of total structural and functional network connectivity (the higher the value, the higher connectivity) for both protein and lipid intake.
There is a notable difference percentage in the weight of MST of the high intake treatment compared with the low intake treatment.Light colors are used for high intake and dark colors for low intake, and the corresponding MST weight values are annotated inside each. Value of difference percentage is annotated in black sub-bar.
