Body weight (a), Lee index (b), body fat percentage (c), and serum TG (d). The body weight in CUGA rats (RN) is remarkably lower than their age-matched controls (NC). No significant difference was observed in Lee index or the body fat percentage of subcutaneous AT (SAT/BW) in R4 compared with N4, in R4N4 compared with N8 (P > 0.05), while the body fat percentage of visceral AT (VAT/BW) was lower in R4 than that in N4 and greater in R4N4 than that in N8 (P < 0.05). The serum TG was greater in R4N4 than that in N8 (P < 0.05). (*P < 0.05 vs. age-matched normal chow controls, all data are mean ± SE)
