The Claim

In obese adults with metabolically healthy obesity, a baseline Fatty Liver Index (FLI) score of 60 or higher is associated with a 37% increased risk of transitioning to a metabolically unhealthy phenotype over a median follow-up of 4.8 years, independent of age, sex, physical activity, and insulin resistance as measured by the TyG index.

In plain English

Obese adults with a Fatty Liver Index score of 60 or higher have a 37% higher rate of developing metabolic dysfunction over nearly five years, even after accounting for age, sex, physical activity, and insulin resistance.

See the scientific wording

In obese adults with metabolically healthy obesity, a baseline Fatty Liver Index (FLI) score of 60 or higher is associated with a 37% increased risk of transitioning to a metabolically unhealthy phenotype over a median follow-up of 4.8 years, independent of age, sex, physical activity, and insulin resistance as measured by the TyG index, suggesting hepatic steatosis serves as a clinically relevant predictor of metabolic deterioration.

Why this might work

Excess fat builds up in the liver, which damages liver cells and disrupts how the liver responds to insulin. This causes the liver to make too much sugar and release harmful fats into the blood. The damaged liver also releases chemicals that create widespread inflammation and oxidative stress, which blocks insulin action in fat and muscle tissue. Together, this forces the body into a state of metabolic failure, turning healthy obesity into unhealthy obesity.

    Obese people with a lot of fat in their liver, as shown by a simple score based on waist size, triglycerides, BMI, and liver enzymes, were 37% more likely to develop problems like high blood pressure and high blood sugar over the next few years—even if they were otherwise healthy at the start.
