虽然饮食诱导的肥胖症完全归因于脂肪热量摄入增加,但随意饲喂高脂肪饮食(HFD)的动物在白天和晚上频繁进食,扰乱了正常的喂养周期。为了测试肥胖症和代谢疾病是否由HFD或代谢周期的破坏引起,我们使小鼠接受HFD的随意或时间限制性喂养(tRF)8小时/天。在tRF下的小鼠从HFD消耗的卡路里与那些随意获取的小鼠相等,但被保护免于肥胖、高胰岛素血症、肝脂肪变性、炎症,并且具有改善的运动协调。tRF方案可改善CREB、mTOR和AMPK通路的功能,改善生物钟的振荡及其靶基因的表达。分解代谢和合成代谢途径的这些变化改变了肝脏代谢组,改善了营养利用和能量消耗。我们在小鼠中证明了tRF方案是一种针对肥胖和相关疾病的非药物策略。
While diet-induced obesity has been exclusively attributed to increased caloric intake from fat, animals fed high fat diet (HFD) ad libitum (ad lib) eat frequently throughout day and night disrupting the normal feeding cycle. To test whether obesity and metabolic diseases result from HFD or disruption of metabolic cycles, we subjected mice to either ad lib or time restricted feeding (tRF) of a HFD for 8 h/day. Mice under tRF consume equivalent calories from HFD as those with ad lib access, yet are protected against obesity, hyperinsulinemia, hepatic steatosis, inflammation, and have improved motor coordination. The tRF regimen improved CREB, mTOR and AMPK pathway function and oscillations of the circadian clock and their target genes' expression. These changes in catabolic and anabolic pathways altered liver metabolome, improved nutrient utilization and energy expenditure. We demonstrate in mice that tRF regimen is a non-pharmacological strategy against obesity and associated diseases.
