In this initial study we will compare three groups. One group will receive one month of prepared meals that will follow a Mediterranean diet. This group will also receive extensive counseling and education on how to maintain a Mediterranean diet. During the second month of the study this group will be encouraged to continue following a Mediterranean diet by themselves with assistance from a nutritionist. The second group will be asked to continue on their current diet and receive supplements that are important parts of the Mediterranean diet. These supplements will include an omega-3 fatty acid capsule, walnuts and grape juice. A third group will be asked to continue their current diet and level of activity without supplements to serve as a control. We will follow the effects on markers of heart disease risk. We will also determine if patients are able to continue following a Mediterranean diet on their own or whether simply taking supplements is easier.
