Adipose tissue insulin resistance (Adipo-IR) is a primary driver of metabolic and histological abnormalities in obese patients with NAFLD, with worsening Adipo-IR correlating with increased liver fibrosis and hepatic insulin resistance.
For obese individuals with fatty liver, simply having a high BMI is not the only risk factor; the metabolic health of the fat tissue matters significantly. If your fat tissue is insulin resistant, it releases fatty acids that damage the liver. Interventions that improve adipose tissue insulin sensitivity (like weight loss or specific medications like thiazolidinediones) may help reduce liver fibrosis and metabolic risk.
Metabolic parameters, hepatic insulin resistance, and liver fibrosis (but not necroinflammation) deteriorated as quartiles of adipose tissue insulin resistance worsened (all P < 0.01).
Why this rating
Large observational cohort (n=207) with gold-standard metabolic clamps and liver biopsies, though it is cross-sectional regarding the quartile analysis.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
