I checked my cholestrol levels, glocuse levels and doctors said they are fine but i want a second opinion, serum chol = 215 mg/dl, hdl = 37 mg/dl, ldl = 142 mg/dl, serum triglycerides = 178 mg/dl, tchol/hdl = 5.81, hba1c = 6.42?

Your HbA1C level indicates you are in prediabetes and requires further testing. LDL cholesterol is in borderline high level. I wonder about your body weight or BMI and blood pressure. Regular exercise and proper diet along with close monitoring of blood glucose should be considered.

Agree with Dr. Park. Reducing about 10% of your body weight and exercising 30 minutes/day is expected to prevent progression of pre-diabetes and could correct your lipid abnormalities. For healthy diet: http://www.choosemyplate.gov/
