Figure 1.

The effect of ketone salt combined with the ketogenic diet on blood ketone levels in uninjured rats.

Concentrations of β-hydroxybutyrate at baseline and 2 days following gavage in the different groups. One hour after the first gavage is also one hour after starting the KD; 1 hour after the day 2 gavage is 25 hours after starting the KD; and 1 hour after the day 3 gavage is 49 hours after starting the KD. Data are expressed as the mean ± SEM (n = 5 per group). *P < 0.05, vs. control group; #P < 0.05, vs. KD group (two-way analysis of variance and Tukey’s multiple comparisons test).
