Supplementation with extra-virgin olive oil and nuts, providing 1 liter of olive oil per week and 30 gr a day of nuts.~The dietician will personalize the dietary advice by adapting it to the patient's condition, preferences and beliefs, will encourage adherence, and transmit a sense of empowerment. A change in diet with specific, attainable goals will be negotiated between the dietician and the participant.~Dieticians will conduct a phone call once in every 2-week period to assess dietary compliance using a 24-hour food recall, the Mediterranean Diet Adherence Form. MD patients will keep a diet diary for 3 days every two weeks, which they will discuss with the dietician during their scheduled dietician assessment. The Baseline Visit with the dietician can occur either in-person or via video communication software."
