C: Inclusion Criteria

1. Ages 40 years or greater at the time of randomization.
2. Ischemic stroke or TIA no less than 14 days and no more than 6 months before randomization
3. Documentation of insulin resistance as defined by a value over 3.0 on the Homeostasis Model Assessment of insulin sensitivity (HOMA).
4. Both ability and willingness to provide informed consent.
5. Presence of none of the exclusion criteria.

Exclusion Criteria

Permanent Exclusions

1. Severely disabling stroke as indicated by an inability to participate in scheduled follow-up activities.
2. Persons whose ischemic stroke or TIA was related to structural cardiac lesion, significant head trauma, proximal arterial dissection or medical instrumentation.
3. Diabetes mellitus as defined by recent use of medication for diabetes as an out-patient (\*see note below) or two fasting plasma blood sugars \> 126 mg/dL.
4. HgbA1c \> 7.0%.
5. Irreversible medical conditions likely to affect short-term survival or ability to participate in the study protocol. These include:

   * Cancer or other chronic disease with poor prognosis (predicted survival of less than four years).

12. History of bladder cancer.
13. Current participation in a conflicting clinical trial. A conflicting clinical trial is defined as a trial with any of following:

    * Intervention that is known to affect the incidence of stroke or myocardial infarction.
    * Intervention that is an experimental drug.
    * Outcome that includes stroke or myocardial infarction.
    * Exclusion for participation in another trial.

Temporary Exclusions Persons with temporary exclusions may be enrolled as soon as the exclusion has resolved.

1. Alanine aminotransferase (ALT) \>2.5 times the upper limit of normal.
2. Hemoglobin \<8.5 g/dl.
3. Moderate or severe pitting edema of the feet or legs (IRIS grade 3 or 4).
4. Carotid surgery or carotid stenting procedure scheduled (delay randomization until 2 weeks following procedure).
D: Inclusion Criteria:

1. Be able to communicate meaningfully with the investigators and be legally competent to provide written informed consent.

Female patients must be non-lactating and must either be at least one year post-menopausal, or be using adequate mechanical contraceptive precautions (i.e. intrauterine device, diaphragm with spermicide, condom with spermicide), or be surgically sterilized (i.e. bilateral tubal ligation, bilateral oophorectomy). Female patients who have undergone a hysterectomy are eligible for participation in the study. Female patients (except for those patients who have undergone a hysterectomy or a bilateral oophorectomy) are eligible only if they have a negative pregnancy test throughout the study period. Patients on oral contraceptives or an hormonal implant will be excluded (patches are acceptable as they deliver much lower estrogen systemically).

Exclusion Criteria:

1. Any cause of chronic liver disease other than NASH (such as -but not restricted to- alcohol or drug abuse, medication, chronic hepatitis B or C, autoimmune, hemochromatosis, Wilson's disease, alpha1-antitrypsin deficiency).
