The Claim
A higher baseline triglyceride-glucose (TyG) index is associated with a more than threefold increased risk of transitioning from metabolically healthy obesity to a metabolically unhealthy phenotype over a median follow-up of 4.8 years, indicating that systemic insulin resistance is a dominant driver of metabolic deterioration in obesity.
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.
People with a higher triglyceride-glucose index at the start of the study were more than three times as likely to develop metabolic problems over nearly five years, even if they started with obesity without other metabolic issues.
See the scientific wording
A higher triglyceride-glucose (TyG) index at baseline is strongly associated with a more than threefold increased risk of transitioning from metabolically healthy obesity to a metabolically unhealthy phenotype over a median follow-up of 4.8 years, suggesting systemic insulin resistance is a dominant driver of metabolic deterioration in obesity.
Excess fat builds up in the liver, which damages liver cells and disrupts their ability to respond to insulin. This causes the liver to produce too much sugar and release too many fats into the blood. The excess fats and damaged liver cells trigger widespread inflammation and oxidative stress, which blocks insulin action in fat and muscle tissue. As a result, blood sugar and fat levels rise permanently, turning a metabolically healthy obese person into a metabolically unhealthy one.
What the research says
1 studyPeople who are obese but otherwise healthy are much more likely to develop problems like high blood pressure and bad cholesterol if they also have high levels of triglycerides and blood sugar — this study found they’re over three times more likely to get these problems over a few years.
