Resolution of Liver Fat in Non-alcoholic Fatty Liver Disease

NAFLD Clinical Trial

Official title: Rapid Resolution of Human Fatty Liver Disease, the Key to Obesity-related Morbidity and Mortality

Status Completed

Clinical Trial Summary

The major adverse health consequences of obesity occur only when non-alcoholic fatty liver disease (NAFLD) also develops. NAFLD is characterized by abnormal hepatic accumulation of triglycerides and other lipids. The first-line approach to NAFLD management is caloric restriction and weight loss, but these remain difficult to achieve. Little attention has been given to dietary carbohydrate restriction, despite recent reports showing that hepatic de novo lipogenesis, a process that converts dietary carbohydrates into fatty acids in the postprandial state, accounts for approximately 25% of liver triglyceride content in hyperinsulinemic subjects with NAFLD. For comparison, only 15% of the liver triglycerides were derived from dietary fatty acids in patients with NAFLD who had consumed a standardized 30% fat diet for four days before being assessed.

Clinical Trial Description

To establish the time-course of hepatic fat loss in NAFLD subjects on a carbohydrate-restricted diet (<20 g/day), a serial assessments of liver fat during two week diet will be performed. Also, markers of lipid and insulin metabolism, liver function test and changes in gut microbiota during rapid metabolic improvement will be assessed.

The overall aim is to exploit this unique set of human material to determine the specific cellular and molecular pathways that are modified in the early stages of metabolic improvement and fatty liver regression. ;
