Rita Basu, Mayo Clinic
  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.
