Energy balance

Non-alcoholic fatty liver disease (NAFLD) is primarily driven by caloric excess and sedentary lifestyle, with insulin resistance serving as the central pathophysiological mechanism linking metabolic dysfunction to hepatic fat storage and subsequent fibrosis.

NAFLD is fundamentally a disease of energy imbalance. Even without alcohol, consuming more calories than you burn leads to fat storage in the liver, driven by insulin resistance. The most effective way to address this is through lifestyle changes that reduce caloric intake and increase physical activity, thereby improving insulin sensitivity and reducing liver fat.

GoodSupportsHIGH confidence
The current global march of NAFLD as a public health challenge parallels the global upsurge for food intake, increase in per capita income, sedentary lifestyle, increasing body mass index and finally is an expression of an excess of caloric intake over expenditure by an individual... insulin resistance as the pathophysiological hallmark... lipotoxicity as the primary driver of hepatocyte injury.
