Placebo & Exercise Group
PLACEBO COMPARATORParticipants randomized to this group will undergo placebo treatment and an aerobic exercise program.
Low Statin & Exercise Group
EXPERIMENTALParticipants randomized to this group will undergo low statin treatment (Lipitor 20Mg Tablet) and an aerobic exercise program.
High Statin & Exercise Group
EXPERIMENTALParticipants randomized to this group will undergo high statin treatment (Lipitor 80Mg Tablet) and an aerobic exercise program.
Interventions
One tablet by mouth every day for 12 weeks.
One tablet by mouth every day for 12 weeks.
Exercise program of brisk walking and/or slow jogging on a treadmill for 90 minutes of exercise spread over 3 days during week 1, 150 minutes of exercise spread over 5 days during week 2, 225 minutes of exercise over 5 days during week 3 and for the rest of the study.
Eligibility Criteria
You may qualify if:
- Body Mass Index (BMI) between 25-43 kg\^m2
- Sedentary (less than 150 min of physical activity/week during last 6 months)
- Weight stable (no more than 5% change in body weight the previous 3 months)
- \>5% risk for a cardiovascular event in the next 10 years according to the 2013 American College of Cardiology/American Heart Association risk calculator and/or 2 out of 5 metabolic syndrome risk factors(Triglycerides ≥ 150 mg/dL; HDL ≤ 40 mg/dL; Glucose ≥ 100mg/dL; Waist Circumference ≥ 102cm for males, 88cm for females; Blood pressure: ≥ 130mmHg systolic and/or 85mmHg diastolic or being treated for hypertension).
- Stable doses of medications for 90 days

You may not qualify if:
- Smoking
- Use of statins in the last 6 months
- Use of other medications or supplements that affect lipid profiles or body weight in the last 6 months (e.g., fibric acids, bile acid sequestrants, nicotinic acids, fish oil)
- Diagnosis of chronic diseases including CVD, diabetes, other metabolic diseases (e.g., thyroid), cancer, HIV, or acquired immunodeficiency syndrome
- History of abnormal bleeding problems
- Currently taking (within the last 10 days) anti-platelet medication (Plavix), Warfarin, and other anti-coagulants (eliquis, pradaxa, and xarelto) medications
- \>2 fold upper normal limit (UNL) for alanine aminotransferase (ALT) or creatinine
- Women who are pregnant or breastfeeding
- Individuals with polymorphisms known to be associated with susceptibility for statin induced myopathies (tested at screening)
- Currently enrolled in another research study

Limitations and Caveats
The COVID-19 epidemic started in the middle of the trial forcing us to stop recruitment for four months. Furthermore, the continuation of the pandemic slowed recruitment for the rest of the trial and significantly impacted n size. There was also a national dextrose shortage following a hurricane in Puerto Rico. As a result many of the IVGTT were not conducted.
