ClinicalTrials.gov Identifier:
NCT01729078
First received: November 9, 2012

  Purpose

Assessment of glucose metabolism and liver fat after 12 week dietary intervention in pre diabetes subjects. Subjects will be randomized to either high fat (olive oil supplemented),high carb/high fiber (beans supplemented) and high carb/low fiber diets. Glucose metabolism will be assessed by labeled oral glucose tolerance test and liver fat by magnetic resonance spectroscopy pre randomization and at 8 and 12 week after starting dietary intervention.
