Metabolic switching is impaired by aging and facilitated by ketosis independent of glycogen

Figure 9. Keto-adaptation enhances physiological metabolic response to stress. The percent difference in blood (A) glucose, (B) BHB and (C) GKI between saline and epinephrine injections during ad libitum feeding and TRF with SD or KD. Data are represented as group mean ± 1 SEM, * = p < 0.05. For all panels: TRF standard diet n = 6 young, n = 8 aged; TRF ketogenic diet n = 6 young, n = 7 aged.
