Effects of IF and LDF on serum glucose, insulin, IGF-1, and β-hydroxybutyrate levels. Serum concentrations of glucose (a), insulin (b), IGF-1 (c), and β-hydroxybutyrate (d) were quantified in mice that had been maintained for 20 weeks on the indicated feeding regimens. Values are the mean and SEM of determinations made in eight mice per group. Statistical comparisons to the AL-fed group are indicated by * and to the PF group by †: * and †, P ≤ 0.05; ** and ††, P ≤ 0.01; *** and †††, P ≤ 0.001.
