NCT ID NCT05268042
First seen Jun 27, 2026 · Last updated Jul 28, 2026 · Updated 2 times
Summary
This study tests whether a moderately low-carb diet can reduce liver fat and improve how the body uses insulin in teenagers with non-alcoholic fatty liver disease (NAFLD) and obesity. About 80 teens aged 10-17 will follow either a carb-restricted or a low-fat diet for 6 months, with all meals provided for the first 12 weeks. The goal is to see if diet changes can help control the disease without medication.
