The Claim

Obesity is associated with a 3.5-fold increased risk of developing non-alcoholic fatty liver disease (NAFLD) compared to normal weight, based on pooled data from 21 cohort studies involving 381,655 participants.

In plain English

People with obesity have a 3.5 times higher rate of developing non-alcoholic fatty liver disease than people with normal weight.

See the scientific wording

Obesity is associated with a 3.5-fold increased risk of developing non-alcoholic fatty liver disease (NAFLD) compared to normal weight, based on pooled data from 21 cohort studies involving 381,655 participants, indicating a strong epidemiological link between elevated body weight and liver fat accumulation.

Why this might work

When a person has too much body fat, fat cells release large amounts of fatty acids into the blood. The liver takes up these fatty acids and turns them into fat droplets. At the same time, the body becomes less responsive to insulin, which causes the liver to make even more fat and stop breaking down existing fat. This builds up fat in the liver.

  1. Study: Obesity is an independent risk factor for non‐alcoholic fatty liver disease: evidence from a meta‐analysis of 21 cohort studies

    People who are obese are about 3.5 times more likely to get fatty liver disease than people with a normal weight, and this study looked at hundreds of thousands of people to confirm that link.
