Title: Comparison of High Monounsaturated Fat and High Carbohydrate Diets on Glycemic Control and Cardiovascular Risk Factors in Type 2 Diabetes
Brief Summary: The purpose of this proposed randomized, controlled trial is to compare the effects of high monounsaturated fat diets and high carbohydrate diets on body weight, body composition, glycemic control, plasma lipids, and other cardiovascular risk factors over a period of one year. At present, no such studies of free-living subjects have been performed. The specific aims of the proposed project are to test the hypotheses that (1) a high monounsaturated fat diet will produce greater weight loss/body fat loss and more successful weight maintenance than a high carbohydrate diet and (2) a high monounsaturated fat diet will result in an improved lipid profile and better glycemic control than a high carbohydrate diet.

* Stable body weight for the preceding 6 months
* Diagnosis of type 2 diabetes for at least 6 months prior to enrollment

* Hypertriglyceridemia with levels of TG \> 500 mg/dl
* Use of insulin
* Use of specific medications that may alter lipid or glucose metabolism (other than the statins)

B: Inclusion Criteria:

* healthy men and women aged 30 to 65 years who has one or more self-assessed ischemic heart disease risk factors at screening: physical inactivity, overweight or obese (BMI ≥ 25/m2 ), waist circumference (≥ 80 cm for women, ≥ 94 cm for men). In addition, the participants should have the motivation and willingness to be randomized to any of the three groups, and to do their best to follow the given protocol .

Exclusion Criteria:

* no internet access or no access to a computer, smoking, pregnancy, or breast-feeding or planning to become pregnant within the next 12 months, a history of cardiovascular disease, type 2 diabetes, chronic disease / disorders that may affect the results of the study, substance abuse within the past 12 months, regular alcohol consumption \> 21 units / week for men or \> 14 units/ week for women, allergy or intolerance to food groups in the dietary guidelines, supplements with mega doses of nutrients that can have potential impact on ischemic heart disease risk markers (eg . fish oils).
C: Inclusion Criteria:

* BMI\>27
* age\>40
* History of CHD or diabetes in any age or BMI level

Exclusion Criteria:

* Pregnant or lactating women.
* Active drug or alcohol use or dependence that, in the opinion of the site investigator, would interfere with adherence to study requirements.
* Serum creatinine \> 3 mg/dl.
* Liver dysfunction ( ³ 2 fold level of ALT and AST enzymes).
* Participation in another trial in which active intervention is being received.
* Any intestinal problem that would prevent the patient from eating one of the test diets (for example, gastric stapling that might prevent consumption of vegetables).
D: Postmenopausal women ages 50 to 79.
