Clinical Trial Summary

Many metabolic complications can develop after liver transplant including: diabetes, high blood pressure, obesity, heart attacks and stroke. The goal of this study is to look at the safety and effect of 2 well known and established diet regimens on the people who had a prior liver transplant and investigate whether it helps with the control of these comorbidities.


Description:

The Mediterranean diet has been shown to be effective in improving hepatic steatosis, insulin sensitivity, diabetes control and reducing cardiovascular risk in adult patients, but there is no data available for patients who underwent liver transplant. The protein-sparing modified fast (PSMF) diet has been used for years at the Cleveland Clinic to treat adult patients with obesity-related medical problems, but its safety and efficacy has not been established in liver transplant recipients.

Study Design


Intervention

Other:
Control group
Patient will be provided with basic nutrition educational materials that outline principles of a healthy diet, including: moderation, portion control, increased intakes of fruits, vegetables and whole grains and reduced intakes of saturated fat, salt and sugar. Brief education will be provided by the hepatologist without dietitian referral.
Mediterranean diet
Patient will receive verbal diet instruction from the dietitian or from the hepatologist who has received instruction from the dietitian on following the Mediterranean diet.
Protein-Sparing Modified Fast (PSMF)
Patient will be referred to the dietitian for an appointment to discuss the PSMF plan. Protein needs of 1.5 grams/kilogram will be calculated based on patient's actual body weight. Patient will receive verbal instruction from the dietitian, as well as printed materials for reference at home. Dietitian will provide a list of allowed and prohibited foods as per Cleveland Clinic's PSMF diet standards.
