Overview
Brief Summary
The purpose of this study is to study the effects of a structured Mediterranean dietary program on prevention of weight gain, promotion of heart health and prevention of fatty liver disease after liver transplantation.
Detailed Description
Study Hypotheses * A modified Mediterranean diet after liver transplantation results in weight loss, improvement of insulin sensitivity, lipid profiles, blood pressure, BMI, and waist circumference in patients who adhere to the program. * A modified Mediterranean diet after liver transplantation results in relative improvement in cardiovascular outcomes in patients who adhere to the program when compared to standard of care. * A modified Mediterranean diet after liver transplantation results in relative improvement in 10-year ASCVD risk in patients who adhere to the program when compared to standard of care. * A modified Mediterranean diet after liver transplantation decreases the risk of development of NAFLD/NASH/NASH fibrosis in patients who adhere to the program. Study Design: * Single-center, prospective, randomized interventional trial * All eligible post-liver transplant patients during the enrollment period will be invited to participate in the trial. * All enrolled patients will be randomized to the Dietary Intervention (DI) arm or the Standard of Care (SOC) arm. * All patients will be followed for 12 months.

Arms & Interventions
Standard of Care Group
Subjects will participate in a standardized Transplant Nutrition class between day 21-40 as per institutional protocol and will be counseled as per the Mayo Clinic standard of care vis a vis dietary intervention, standard aerobic and resistance exercise recommendations (consistent with AASLD guidelines) and other lifestyle interventions.
Behavioral: Structured Modified Mediterranean Diet
Subjects will participate in a one-on-one counselling session with a dietician, as opposed to attending the standardized Transplant Nutrition class. Counselling will be provided on the elements of the modified Mediterranean diet which emphasizes consumption of fruits, vegetables, whole grains, beans and nuts, in addition to low salt, moderate amounts of lean protein (primarily fish and poultry) in addition to low to moderate quantities of monounsaturated fats.
