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

Figure 2. Keto-adaptation differs by age. (A) Glucose, (B) BHB and (C) GKI levels of young and aged rats consuming either a KD or SD as a function of days on the diet indicate an age-dependent delay in keto-adaptation. Data are represented as group mean ±1 standard error of the mean (SEM), *p<0.05. For all panels: TRF standard diet n = 5 young, n = 4 aged; TRF ketogenic diet n = 5 young, n = 4 aged.
