Caloric Restriction Reverses Hepatic Insulin Resistance and Steatosis in Rats with Low Aerobic Capacity

Abstract: Rats selectively bred for low aerobic running capacity exhibit the metabolic syndrome, including hyperinsulinemia, insulin resistance, visceral obesity, and dyslipidemia. They also exhibit features of nonalcoholic steatohepatitis, including chicken-wire fibrosis, inflammation, and oxidative stress. Hyperinsulinemia in these rats is associated with impaired hepatic insulin clearance. The current studies aimed to determine whether these metabolic abnormalities could be reversed by caloric restriction (CR). CR by… Show more

“…Similarly in rats selectively bred for low aerobic running capacity there is an age related development of the metabolic syndrome, including hyperinsulinemia, insulin resistance, visceral obesity, and dyslipidemia. Hyperinsulinemia in these rats is associated with impaired hepatic insulin clearance (Bowman et al, 2010). These metabolic abnormalities were reversed by 30% CR for 3 months.…”

“…HCR and LCR have been previously subjected to long-term (3 months to 12 months) calorie restrictions at 30% of a similar standard rat chow (Lab Diet no. 5001) with no discernable effects of malnutrition being reported [42]. …”

“…Neste contexto, mudança na adiposidade induzida pela RC pode modular a ação desse hormônio. Em ratos com baixa capacidade aeróbia, 30 % de RC durante 3 meses foram capazes de reverter a resistência à insulina hepática, além de reduzirem a adipogênese no fígado (BOWMAN et al, 2010). Em outro estudo, com ratos idosos, 20 % de RC durante 8 meses reduziram a adiposidade visceral e a massa adiposa total.…”
