According to a recent study, frequently eating takeout food increases the risk of a metabolically induced fatty liver. One gender should be particularly cautious with takeout consumption.
Monday Asian noodles, Tuesday currywurst with fries, Wednesday kebab, Thursday… Stop! This is where it gets critical. Ordering four or more takeout meals per week increases the risk of a metabolically induced fatty liver (MASLD). This condition is associated with metabolic issues like obesity and insulin resistance, not alcohol. The dramatic consequences range from liver inflammation to liver cancer. A Chinese research team found that you don’t have to be an extreme “fast-food junkie” for this risk, as detailed in a study published in the “American Journal of Epidemiology.”1
This Is What the Researchers Wanted to Find Out
It’s clear that ready-made meals don’t fall into the “clean eating” category. However, previous studies say little about the quantity at which it becomes unhealthy or even dangerous for the liver. The liver is known to be a very patient organ that can endure a lot until it can’t anymore. Particularly insidious: Once the damage is done, there are often no noticeable symptoms. Therefore, the researchers wanted to know if frequent takeout consumption is related to the occurrence and severity of a metabolically induced fatty liver. According to their data, MASLD now affects about 30 percent of the global population.
This Is How It Was Studied in 3 Cohorts
The Chinese cohort included 3,186 adults who did not have fatty liver at the start of the study. Their takeout consumption was recorded using questionnaires. During the observation period of 12,941 person-years, 724 developed MASLD. Additionally, data from 99,781 people from the UK Biobank were included. Here, too, the amount of takeout food was recorded via questionnaires. The 724 fatty liver diagnoses made within 1,033,546 person-years were determined using hospital data and death registers. The third cohort included 334 Chinese adults with biopsy-confirmed MASLD. This allowed the researchers to examine not only whether takeout consumption was linked to fatty liver but also whether it was associated with the severity of the disease. The comparison group consisted of those who indulged in to-go food less than once a week.
Does Takeout Food Cause Fatty Liver? Here’s What the Analysis Revealed
There appears to be a significant link between takeout food and metabolically induced fatty liver, particularly among men. For them, the risk increased by about 30 percent with four takeout meals. Interestingly, below this threshold, the risk of fatty liver was not significantly elevated. It seems that one extra junk food session per week makes the crucial difference. The British study even confirmed a 66 percent higher risk for men, while women did not seem to be affected. The third cohort provided the crucial evidence that takeout food can worsen the severity of an existing fatty liver.

Researchers Suspect Other Reasons Besides Too Much Salt and Fat
They believe that high amounts of salt, fat, and sugar, combined with low fiber and micronutrients, play a crucial role. Problematic chemicals like BPA or phthalates, which can transfer from plastic packaging to food, are also suspected. The study does not specify how each component contributes. Why women remain unaffected by fatty liver despite a love for takeout is also a mystery.
Simple Behavioral Message for Men
Although the study mainly relies on self-reported observational data from participants and cannot prove that takeout food directly causes fatty liver, it has some significant strengths. The greatest is the combination of three datasets with over 100,000 people from different populations. The third cohort is particularly valuable as it confirms results through liver biopsies. What men, especially those who care about their liver, should take away from the study: When it comes to takeout food, don’t have it more than three times per week. Additionally, it seems not only ecologically sensible to bring your own reusable containers when picking up food. Make sure they don’t contain plasticizers or other problematic substances. Ideal options include containers made of stainless steel.
