Details and patient eligibility

About

This is an open-label, randomized study comparing a monitored ketogenic diet intervention using standard ketogenic diet (SKD) and standard of care (SOC) dietary recommendations for 16 weeks. Subjects enrolled in the standard of care group will receive a voucher to Weight Watchers after study completion.

Full description

The primary aim is to assess the safety of ketogenic diet as compared to standard of care approach for weight loss in patients with compensated cirrhosis due to NASH. The safety endpoints captured in the study include liver decompensation events, measured through several questionnaires, fasting blood glucose, serum creatinine, fasting lipid profile and other adverse events. The tolerability of the ketogenic diet will be assessed by study compliance and by administering a questionnaire.

Secondary aims include weight loss, changes in body composition via serial use of bioelectrical impedance via an Inbody Machine, changes in liver fat and liver stiffness using MRI and proton density fat fraction (MRI-PDFF), liver biochemistries, changes in Child-Turcotte-Pugh and MELD scores measured via labs and changes in liver steatosis and stiffness via serial measures of VCTE by FibroScan®.

40 participants in 2 patient groups

Ketogenic diet
Active Comparator group
Description:
For participants randomized to the ketogenic diet arm, a consultation with the providers of medically supervised weight loss clinic of Indiana University Health will be arranged. Subjects will be educated on the concepts of ketosis, symptoms associated with it, and dietary manipulation to achieve ketosis. Participants in this arm will use the suggested recipes in combination with strict carbohydrate monitoring though checking for urine ketone bodies. These recipes were gathered and vetted by the dietitian at the medically supervised weight loss clinic. We anticipate that this approach will allow for more calorie intake and easier carbohydrate restriction. The follow up visits will be determined by the providers of the medically supervised weight loss clinic based on the symptoms reported and subject's compliance with carbohydrate restriction.

Other: Dietary consult for participants in the ketogenic diet arm
Standard of Care
Sham Comparator group
Description:
For participants randomized to this arm, a consultation with the providers of medically supervised weight loss clinic will be arranged. The discussion will focus on portion control using a balanced diet. A follow up visit will be at 16 weeks. This is the extent of interventions received for participants in this arm.
Treatment:
Other: Dietary consult for participants in the standard of care arm
