The Claim
For every one-unit increase in body mass index (BMI), the risk of developing non-alcoholic fatty liver disease increases by 20%.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Higher body mass index (BMI) is directly associated with a 20% higher risk of developing non-alcoholic fatty liver disease for each one-unit increase in BMI.
See the scientific wording
For every one-unit increase in body mass index (BMI), the risk of developing non-alcoholic fatty liver disease increases by 20%, based on a meta-analysis of 21 cohort studies with 381,655 participants, indicating a consistent dose-response relationship between BMI and NAFLD risk.
Extra body fat releases more fatty acids into the blood, which the liver takes up and stores as fat. At the same time, the body becomes less responsive to insulin, so the liver keeps making more fat and stops breaking it down. This builds up fat in the liver over time.
What the research says
1 studyThis big review of over 380,000 people found that for every point your BMI goes up, your chance of getting fatty liver disease goes up by about 20% — so even a little extra weight adds up in risk.
