The investigators' aim is to determine whether probiotic and prebiotic treatment plus lifestyle advice is more effective in reducing hepatic fat content than lifestyle advice alone in patients with Nonalcoholic Fatty Liver Disease (NAFLD).

Condition Intervention
Nonalcoholic Fatty Liver Disease
Drug: Lepicol probiotic & prebiotic formula
Other: Simple lifestyle advice

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Outcomes Assessor)

Primary Outcome Measures:
  • The primary endpoint is the reduction in hepatic triglyceride content from baseline to week 24. [ Time Frame: 24 weeks ]

Secondary Outcome Measures:
  • The proportion of patients with normal ALT at week 24 will be determined. Normal ALT is defined according to Prati's cutoffs (≤30 IU/l in men and ≤19 IU/l in women). [ Time Frame: 24 weeks ]
  • The proportion of patients with impaired fasting glucose, diabetes, insulin resistance (estimated by the homeostasis model), hypertension, dyslipidemia and metabolic syndrome will be determined both at baseline and during each visit. [ Time Frame: 24 weeks ]
  • The changes in visceral fat will be determined by magnetic resonance imaging at the same session both at baseline and month 12. [ Time Frame: 12 months ]
  • The changes in liver fibrosis will be determined by transient elastography by Fibroscan both at baseline and month 12. [ Time Frame: 12 months ]
  • The percentage of total sequences of individual microbes will be calculated. In particular, the proportion of Firmicutes and Bacteroidetes will be compared between the two treatment arms. [ Time Frame: 12 months ]
