Summary

Numerous studies have established the role of nutrition on obesity and its related metabolic diseases, which together affect a billion individuals worldwide. Evidence indicate that meal timing regulates numerous metabolic processes suggesting that meal time manipulation may be a simple intervention against obesity and its metabolic diseases. Time-restricted eating (TRE) is a dietary manipulation that involves restricting food intake to 6-10 h/day with no energy intake the rest of the day. In rodents, TRE significantly decreases hepatic steatosis and dyslipidemia, while it supports a healthier hepatic cellular content even without caloric restriction, potentially by alternating activation of nutrient sensing mechanisms and effects on circadian oscillations. However, an understanding of the effect of TRE on liver health in people is not clear. Accordingly, we will conduct a randomized controlled trial in people with overweight/obesity and hepatic steatosis to determine the effect of 9 h TRE for 12 weeks, on key metabolic outcomes in liver health: 1) intrahepatic triglyceride content using magnetic resonance imaging; 2) de novo lipogenesis during fasting and postprandial conditions using administration of deuterated water in conjunction with mathematical modeling. The proposed study will enable us to determine the effect of meal timing on metabolic function in people with NAFLD.
