According to Gram Research analysis, men who eat takeaway food four or more times per week have approximately 30% higher risk of developing MASLD (metabolic dysfunction-associated steatotic liver disease) compared to those eating takeout less than once weekly, according to a 2026 international study of over 103,000 adults. In the UK population studied, the risk jumped to 66% higher for any takeout consumption. The disease involves fat accumulation in the liver and can lead to serious complications if left untreated.
A major international study following over 100,000 people discovered that eating takeaway food frequently—especially four or more times per week—increases the risk of developing a serious liver disease called MASLD (metabolic dysfunction-associated steatotic liver disease). Researchers in China and the UK tracked participants over many years and found that men who ate takeout most often had significantly higher chances of developing this condition. The study included people with biopsy-proven liver disease, making the findings especially reliable. This research suggests that reducing takeout consumption could be an important way to protect your liver health.
Key Statistics
A 2026 international cohort study of 103,001 adults found that men consuming takeaway food 4+ times weekly had a 30% increased risk of developing metabolic dysfunction-associated steatotic liver disease (MASLD) compared to those eating takeout less than once per week.
According to a 2026 study published in the American Journal of Epidemiology, UK Biobank participants who consumed any takeaway food showed a 66% higher risk of MASLD compared to non-consumers, with the association particularly strong in men.
A 2026 multicohort analysis of 334 Chinese adults with biopsy-verified MASLD found that takeaway food consumption was positively associated with disease severity, suggesting that frequent takeout consumption not only increases disease risk but also worsens outcomes.
Research reviewed by Gram found that the increased MASLD risk from frequent takeout consumption remained significant even after adjusting for body weight, exercise, smoking, and alcohol use, indicating an independent harmful effect of takeaway foods.
The Quick Take
- What they studied: Whether eating takeaway food frequently causes a type of liver disease where fat builds up in the liver (MASLD)
- Who participated: Over 103,000 adults from China and the UK, plus 334 people with proven liver disease. Most participants were tracked for several years to see who developed the disease
- Key finding: Men eating takeout 4+ times per week were 30% more likely to develop liver disease in China, and 66% more likely in the UK compared to those eating takeout less than once weekly
- What it means for you: Limiting takeaway food to less than once per week may help protect your liver. This is especially important for men. However, other lifestyle factors like exercise and overall diet also matter significantly
The Research Details
This was a large international study that followed two main groups of people over time. The first group came from China (3,186 people) and the second from the UK (99,781 people). Researchers asked participants how often they ate takeaway food and then tracked their health for several years using medical records and ultrasound scans. A third group of 334 Chinese adults had their livers examined with biopsies (tissue samples) to confirm they had the disease. This multi-country approach with biopsy confirmation makes the findings more trustworthy because researchers could verify the disease in real tissue, not just rely on scans or self-reporting.
The researchers used statistical methods called Cox proportional hazards regression to calculate the risk of developing liver disease at different levels of takeout consumption. They adjusted their calculations to account for other factors that might affect liver health, like age, weight, exercise, smoking, and alcohol use. This helps isolate the specific effect of takeout food itself.
Following people over time (rather than just asking them about their health once) is the gold standard for understanding how food choices affect disease risk. By studying two different countries with different populations and food cultures, the researchers could see if the pattern held true across different groups. Including people with biopsy-confirmed disease adds credibility because it proves the disease actually existed, rather than relying solely on imaging or blood tests
This study is strong because it’s large (over 100,000 people), follows participants over years, and includes biopsy-verified cases. It was published in a respected medical journal. However, the study relied on people remembering how often they ate takeout, which can be inaccurate. The findings were stronger in men than women, suggesting sex differences that aren’t fully explained. The study shows association (correlation) but cannot prove that takeout food directly causes the disease
What the Results Show
In the Chinese study group, men who ate takeout 4 or more times per week had a 30% higher risk of developing liver disease compared to those eating it less than once weekly. Interestingly, men eating takeout 1-3 times per week actually showed slightly lower risk, which was unexpected. In the much larger UK study, the pattern was clearer: men who ate any takeout food had a 66% higher risk compared to men who never ate takeout. The difference between countries may reflect different types of takeout food or other lifestyle differences.
When researchers looked at the 334 people who already had confirmed liver disease, those who ate takeout frequently had more severe disease. This suggests that takeout consumption doesn’t just increase the risk of developing the disease—it may also make the disease worse once someone has it.
The findings were much stronger in men than in women. Women showed little to no increased risk from takeout consumption in either study group. This sex difference is important and suggests that men may be more vulnerable to the liver-damaging effects of takeout food, possibly due to differences in metabolism or how their bodies process certain nutrients.
The study found that the relationship between takeout food and liver disease remained significant even after accounting for other important factors like body weight, exercise habits, smoking, and alcohol consumption. This suggests that takeout food has an independent effect beyond just contributing extra calories. The severity of liver disease in people who already had the condition correlated with how often they ate takeout, indicating a dose-response relationship (more takeout = worse disease)
Previous research has shown that ultra-processed foods and high-calorie diets increase liver disease risk, but this is one of the first large studies specifically examining takeaway food. The findings align with what we know about processed foods being high in unhealthy fats, sodium, and added sugars—all of which can harm the liver. This study provides stronger evidence than previous smaller studies and confirms the pattern across different populations
The study asked people to remember how often they ate takeout, which can be inaccurate. People’s eating habits may have changed over time, but the study only measured them once at the beginning. The findings were much stronger in men, so we can’t confidently apply them to women. The study shows that takeout consumption and liver disease are connected, but it cannot prove that takeout directly causes the disease—other unmeasured factors could be involved. Different types of takeout food (fast food vs. restaurant delivery) weren’t distinguished
The Bottom Line
Men should aim to eat takeaway food less than once per week to reduce liver disease risk (moderate confidence). The evidence is strongest for men; women may have lower risk. Combine this with other healthy habits: regular exercise, maintaining a healthy weight, limiting alcohol, and eating more home-cooked meals with vegetables and whole grains. If you already have liver disease or risk factors like obesity or diabetes, reducing takeout is especially important
This research is most relevant to men, particularly those with risk factors for liver disease (obesity, diabetes, metabolic syndrome, or heavy alcohol use). People with a family history of liver disease should pay special attention. Women showed minimal risk in this study, but healthy eating is beneficial regardless. Anyone concerned about their liver health should discuss their diet with their doctor
Liver disease develops gradually over years, so you won’t see immediate changes. However, reducing takeout consumption can help prevent future disease development or slow progression if disease is already present. Most benefits would likely appear over months to years of consistent dietary change
Frequently Asked Questions
How often can I eat takeout food before it damages my liver?
Research shows men should limit takeout to less than once per week to reduce liver disease risk. The study found that 4+ times weekly significantly increased risk. Women showed minimal risk in this research, but moderation is still healthy. Individual risk varies based on overall diet and lifestyle factors.
What is MASLD and why does takeout food cause it?
MASLD is a condition where fat builds up in the liver due to metabolic problems. Takeout foods are typically high in unhealthy fats, sodium, and added sugars—nutrients that promote fat storage in the liver. The exact mechanisms aren’t fully understood, but these foods appear to trigger inflammation and metabolic dysfunction.
Does this study apply to women or just men?
The study found much stronger associations in men than women. Women showed little to no increased risk from takeout consumption in either the Chinese or UK populations studied. However, healthy eating benefits everyone, so reducing takeout is still recommended for overall health.
Can I reverse liver damage by stopping takeout food?
The study didn’t examine whether stopping takeout reverses existing disease. However, reducing takeout combined with weight loss, exercise, and other healthy habits can slow disease progression and prevent complications. Consult your doctor about your specific situation and liver health status.
What types of takeout food are most harmful to the liver?
The study didn’t distinguish between different types of takeout. However, foods high in saturated fats, trans fats, sodium, and added sugars are generally most harmful to liver health. This includes fast food, fried foods, and heavily processed restaurant meals. Home-cooked meals with whole grains and vegetables are healthier alternatives.
