Plasma BHB concentrations of weanling rats fed different diets for four weeks.
Notes: Plasma was obtained after an overnight food withdrawal for 10–12 hours (see the Methods and Materials section). Significance of difference among diet groups by one-way ANOVA, P < 0.001. error bars represent ± SEM (n = 5); a, b, means not sharing common letter significantly differ (P < 0.05; Tukey test after logarithmic transformation).
Feeding protocol: LZ-CB, fed the LZ diet (7 mg/kg diet) with 22% CB free choice; HZ-CBR, fed the HZ diet (50 mg/kg) with 22% CB in restricted amounts according to intake in the LZ-CB group; LZ-SF, fed the LZ diet with 22% SF oil free choice; HZ-SFR, fed the HZ diet with 22% SF oil in restricted amounts according to intake in the LZ-SF group; and HZ-SF, fed the LZ diet with 22% SF oil free choice.
