Macro partitioning
High-fructose intake contributes to NAFLD pathogenesis by promoting de novo lipogenesis, hepatic insulin resistance, and leptin resistance.
Limit high-fructose corn syrup and added sugars. High fructose intake drives liver fat production and insulin resistance independently of weight gain. Focus on reducing processed foods and sugary drinks rather than eliminating all natural fruit sources.
ModerateSupportsMEDIUM confidence
High-fructose diets in humans are associated with increased energy intake, weight gain, increased fat mass and increased blood pressure after only 10 weeks. They have also been associated with increased hepatic DNL, hypertriglyceridaemia and the development of hepatic insulin resistance.
Why this rating
Based on human and animal studies showing metabolic effects; large long-term histology trials specifically on fructose are less emphasized than general weight loss.

- Diet-induced weight loss of approximately 10% of body weight significantly improves hepatic steatosis, necroinflammation, and insulin resistance in patients with NAFLD/NASH, with histological improvement correlating with the magnitude of weight loss.Moderate
- Exercise alone, independent of significant weight loss, improves insulin sensitivity, visceral fat, and glucose metabolism in obese individuals with NAFLD.Moderate
