The following criteria are to be checked at the time of enrolment. The patient may only be included in the study if ALL of the following statements are FULFILLED:

1. The patient is an existing participant of the ELEGANCE study and shows no evidence of hepatocellular carcinoma (HCC) at the time of enrolment into RE-BALANCE.

3. Negative for hepatitis B surface antigen (HBsAg) and hepatitis C antibody
4. High-risk bile acid profile, defined as a 12-non-hydroxy/12-hydroxy bile acid ratio below the threshold determined from ELEGANCE cohort data.
5. Patient is able to comply with scheduled visits, assessments and other study procedures.
6. Patient is willing to provide informed consent before enrolment in the study.

Exclusion Criteria:

The following criteria should be checked at the time of enrolment. If ANY applies, the patient must not be included in the study:

1. Patient with confirmed diagnosis of HCC by the American Association for the Study of the Liver Disease (AASLD) imaging criteria or histology / cytology within the last 5 years.
2. Patient with Child Pugh C or decompensated cirrhosis at time of enrolment (based on the judgement of the Investigator).
3. Patient with active hepatic encephalopathy at time of enrolment.
4. Patient is known to be positive for the Human Immunodeficiency Virus (HIV).

10. Patient has significant gastrointestinal diseases affecting nutrient absorption or requiring a special diet incompatible with study diet.
11. Pregnancy or breastfeeding
12. Current use of medications or supplements that significantly alter bile acid gastrointestinal absorption (e.g., bile acid sequestrants) that cannot be safely discontinued.
13. Patient has severe food allergies or intolerances incompatible with the provided study diet.
