The chronic administration of acarbose has been shown to improve insulin resistance and reverse impaired glucose tolerance. Both these conditions, especially insulin resistance, are physiologically associated with the development and progression of NAFLD. Therefore, we hypothesized that the chronic administration of acarbose attenuates NAFLD by improving glucose handling. This would be reflected in a reduction of intrahepatic fat accumulation. Proton Magnetic Resonance Spectroscopy is a sensitive and non-invasive method to measure changes in intrahepatic fat content. The primary endpoint of this study would be to demonstrate a reduction of intrahepatic fat as measured with Proton Magnetic Resonance Spectroscopy after 12 weeks administration of oral acarbose. Other relevant secondary outcomes that have been previously demonstrated to be associated with improvement of NAFLD included improvement of insulin resistance, normalizing of serum adiponectin, and a lowering of serum Leptin.
