Animal body weight analysis. Data presented as change in body mass, showed as mean ± SEM representative for the group tested for the longest period. Analysis was performed for 3 weeks before and 4 weeks after brain surgery. Dashed line marks the day of operation. p value ≤ 0.05 was set as significance threshold and marked as * vs. normal diet + sham, L vs. normal diet + 6-OHDA lesion, K vs. ketogenic diet + sham. Repeated measure ANOVA with LSD post hoc test for analysis in time and 3-way ANOVA with LSD post hoc test for analysis of total values were performed. Number of animals in groups was: for NS n = 16; for NL n = 14; for KS n = 17; for KL n = 16.
