Inclusion Criteria:

1. Subjects aged between 18 and 60 years (inclusive) at first screening visit.
2. Must provide signed written informed consent and agree to comply with the study protocol.
3. BMI between 35 and 45 kg/m2 with or without metabolic risk factors (type 2 diabetes, arterial hypertension, dyslipidaemia), and BMI between 30 and 34,9 kg/m2 with type 2 diabetes.

4. Histological confirmation of steatohepatitis in a diagnostic liver biopsy (biopsy obtained in the 6 months prior to randomization or during the selection period) with at least a score of 1 in each component of the NAS score (steatosis with a score of 0 to 3, degeneration by ballooning with a score of 0 to 2 and lobular inflammation with a score of 0 to 3) and:

   • NAS score ≥ 4
   • fibrosis < 4 according to the staging system of CRN fibrosis on NASH
5. For patients with fibrosis ≤ 1, must be associated at least one of the following conditions: metabolic syndrome (NCEP ATP III definition), type 2 diabetes, HOMA-IR >6
6. Absence of other well documented causes of chronic liver disease (alcoholic liver disease, viral hepatitis, cholestasis, autoimmune hepatitis, Wilson's disease, hemochromatosis, alpha 1 antitrypsin deficiency)
7. Patients agree to have 1 liver biopsy after 96 weeks after intervention

Exclusion Criteria:

1. Known heart failure (Grade I to IV of the classification of the New York Heart Association).
2. History of efficient bariatric surgery within 10 years prior to Screening.
3. Patients with a history of clinically significant acute cardiac event in the 6 months prior to selection, such as: acute cardiovascular event, cerebrovascular accident, transient ischemic attack, or coronary heart disease (angina pectoris, myocardial infarction, revascularization procedures).
4. Weight loss of more than 5% in the 6 months prior to randomization.
5. Recent or current background of significant consumption of alcoholic beverages (<5 years). In the case of men, significant consumption is usually defined as more than 30 g of pure alcohol per day. In the case of women, it is usually defined as more than 20 g of pure alcohol per day.
6. Liver cirrhosis.
7. Non-cirrhotic portal hypertension.
8. Esophagogastric varices.
9. Hepatocellular carcinoma
10. Portal thrombosis.
11. Pregnancy.
12. Refusal to give informed consent.
13. Any medical condition that could reduce life expectancy to less than 2 years, including known cancers.
14. Signs of any other unstable or clinically significant immunological, endocrine, hematological, gastrointestinal, neurological, neoplastic or psychiatric disease without treatment.
15. Instability or mental incompetence, so that the validity of the informed consent or the ability to comply with the study are uncertain.
16. Antibodies positive for the human immunodeficiency virus.

17. Descompensated liver disease with the following hematologic and biochemical criteria:

    • Aspartate aminotransferase (AST) and / or ALT> 10 x upper limit of normal (ULN)
    • Total bilirubin> 25 μmol / l (1.5 mg / dl)
    • Standardized international index> 1.4
    • Platelet count <100 000 / mm3
18. Serum creatinine levels> 135 μmol / l (> 1.53 mg / dl) in men and> 110 μmol / l (> 1.24 mg / dl) in women.
19. Significant renal disease, including nephritic syndrome, chronic kidney disease (patients with markers of hepatic injury or estimated glomerular filtration rate [eGFR] of less than 60 ml / min / 1.73 m2). If an abnormal value is obtained at the first screening visit, the eGFR measurement may be repeated before randomization within the following time frame: minimum 4 weeks after the initial test and maximum 2 weeks before the expected randomization. An abnormal repeated eGFR (less than 60 ml / min / 1.73 m2) leads to exclusion from the study.
