Eating late at night increases the risk of developing liver diseases such as fatty liver disease and cirrhosis by 20 to 30 percent, according to a large-scale study published in Clinical Gastroenterology and Hepatology.
The study examined data sourced from three major United States cohorts, which included the Nurses’ Health Study, the Nurses’ Health Study II, and the Health Professionals Follow-Up Study. Lead author and OHSU liver transplant specialist Robert Wilechansky stated that while previous research linked nocturnal snacking to obesity and heart conditions, this investigation focuses directly on the long-term connection between late-night eating and fatty liver disease. Researchers emphasized these findings do not prove late eating directly causes liver disease, but rather establish a correlation.
Biological Clocks and Circadian Rhythms Disrupt Nutrient Processing
The human liver operates in close coordination with the body’s biological clock, regulating energy use, sleep, and daily physiological functions. Co-author and OHSU sleep and circadian researcher Andrew McHill explained that consuming food while the body actively prepares for sleep makes it significantly harder to process nutrients efficiently. Animal experiments previously demonstrated how eating schedules misaligned with normal sleep cycles negatively affect the liver.
Future Research Focuses on Dietary Timing Adjustments
Researchers intend to launch subsequent studies to track whether shifting meal times earlier in the day actively improves liver function for individuals diagnosed with fatty liver disease. Future trials will closely monitor the specific eating schedules of affected patients to measure clinical changes. Meanwhile, dietician Ayça Doğandemir, speaking to Türkinform, highlighted that nighttime eating often stems from restricted daytime nutrition or skipped meals rather than physical hunger alone.
