Background: Hyperinsulinemia due to reduced insulin clearance and excess insulin secretion is a key feature of insulin resistance and is influenced by multiple factors, such as hepatic response to insulin action, dietary and circulating fat, and ethnic background
Background: Hyperinsulinemia due to reduced insulin clearance and excess insulin secretion is a key feature of insulin resistance and is influenced by multiple factors, such as hepatic response to insulin action, dietary and circulating fat, and ethnic background
Objectives: Here, we tested the hypothesis that, in the absence of significant changes in body weight, a low n–6:n–3 PUFA ratio diet could alter the metabolic phenotype of obese youth with NAFLD by increasing insulin clearance
