(A–C) Body weight, fat-free mass (FFM), and fat mass (FM) at baseline. (D) %Δ body weight. Diet main effect, p = 0.004; age group main effect, p = 0.044; diet × age group interaction, (p = n.s.). § diet effect (same age) in the old group: ST12 vs. HF12, p = 0.039; * age effect (same diet) in ST12 rats, p = 0.013. (E) %Δ fat-free mass (FFM): § diet effect (same age) in the old group ST25 vs. ST12, p = 0.048. (F) %Δ fat mass (FM): diet main effect, p < 0.001; age group main effect, n.s.. § diet effect (same age) in the adult group: HF12 vs. ST12, p = 0.007; HF12 vs. ST25, p = 0.007. § diet effect (same age) in the old group HF12 vs. ST12, p < 0.001, and HF12 vs. ST25, p < 0.001. Adult rats: ST12 (n = 12); ST25 (n = 12); HF12 (n = 12); HF25 (n = 11). Old rats: ST12 (n = 11); ST25 (n = 11); HF12 (n = 9); HF25 (n = 7).
