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.
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®.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Ketogenic diet | Active Comparator | 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. |
|
| Standard of Care | Sham Comparator | 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. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Dietary consult for participants in the ketogenic diet arm | Other | An initial consultation with the providers of medically supervised weight loss clinic will be arranged. Participants in the ketogenic diet group will be educated on the concepts of the diet and will be provided with recipes to be utilized at home that adhere to this diet. In addition to the initial consultation, participants in this arm receive additional consultations with these providers with a frequency as determined by the provider. |
| Measure | Description | Time Frame |
|---|---|---|
| Blood chemistry to assess for liver de-compensation events | Blood will be drawn serially to assess fasting blood glucose, serum creatinine and fasting lipid profile. | Blood chemistry tests will be assessed at the initial visit. |
| Blood chemistry to assess for liver de-compensation events | Blood will be drawn serially to assess fasting blood glucose, serum creatinine and fasting lipid profile. | Blood chemistry tests will be assessed at the study visits between weeks 5 and 14. |
| Blood chemistry to assess for liver de-compensation events | Blood will be drawn serially to assess fasting blood glucose, serum creatinine and fasting lipid profile. | Blood chemistry tests will be assessed at the Week 16 visit. |
| Adverse events | All participants will be monitored for adverse events and/or serious adverse events throughout the duration of the trial. | All participants will be monitored at the study visits between weeks 5 and 14 and all participants will be instructed to alert the study team for additional information if such an event occurs. |
| Adverse events | All participants will be monitored for adverse events and/or serious adverse events throughout the duration of the trial. | All participants will be monitored at the week 16 visit and all participants will be instructed to alert the study team for additional information if such an event occurs. |
| Tolerability of the ketogenic diet | How well the ketogenic diets is tolerated will be assessed by administering a POMS40 questionnaire. |
| Measure | Description | Time Frame |
|---|---|---|
| MRI with proton density fat fraction (PDFF) | MRI-PDFF is a convenient method for liver fat quantification and currently used in most clinical trials, as it only requires a single 20-second breath hold and an estimated time of about 5 minutes in an MRI scanner suite. MRI in the study will be used to quantify liver steatosis, stiffness, and body composition. | Performed at initial visit and at week 16 visit |

Block randomization will be utilized to ensure balancing of treatment groups throughout enrollment. 30 participants will be assigned to the ketogenic diet arm and 10 will be assigned to standard of care.

While this is an open label study, the principal investigator will be blinded to the results of efficacy outcomes such as MRI-PDFF, Body composition data, VCTE by FibroScan® and study questionnaires.
|
| Dietary consult for participants in the standard of care arm | Other | For participants in the standard of care arm, an initial consultation with the providers of medically supervised weight loss clinic will be arranged and the discussion will center around portion control using a balanced diet. Participants will receive only one additional consultation with the provider 16 weeks later just prior to the conclusion of the study. |
|
| The POMS 40 questionnaire is administered at the initial visit. |
| Tolerability of the ketogenic diet | How well the ketogenic diets is tolerated will be assessed by administering a POMS40 questionnaire. | The POMS 40 questionnaire is administered at the study visits between weeks 1 and 4. |
| Tolerability of the ketogenic diet | How well the ketogenic diets is tolerated will be assessed by administering a POMS40 questionnaire. | The POMS 40 questionnaire is administered at the Week 16 visit. |
| Weight loss and change in body composition | Changes in weight and body composition will be measured via serial use of a scale and use of bioelectrical impedance via an Inbody machine | Performed at initial visit and at week 16 visit |
| Changes in liver stiffness and steatosis | Changes in liver stiffness and steatosis will be measured with serial use of vibration controlled transient elastography (VCTE) via a FibroScan. | Performed at initial visit and at week 16 visit |
