What this trial studies

This clinical trial involves a 6-month randomized approach comparing a moderately carbohydrate-restricted diet to a fat-restricted control diet in adolescents diagnosed with Non-Alcoholic Fatty Liver Disease (NAFLD). The study consists of two phases: a 12-week controlled feeding phase where all meals are provided, followed by a 12-week 'free living' phase. Participants will be children and adolescents aged 10-17 years who are overweight or obese, with specific criteria for liver health. The goal is to assess the impact of dietary changes on liver health and insulin sensitivity.

Who should consider this trial

Good fit: Ideal candidates are adolescents aged 10-17 years who are overweight or obese and have a clinical diagnosis of NAFLD.

Not a fit: Patients with uncontrolled diabetes, liver infections, or those on medications affecting liver health may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved liver health and metabolic outcomes for adolescents with NAFLD.

How similar studies have performed: Previous studies have shown that carbohydrate-restricted diets can improve liver health and insulin sensitivity in similar populations, indicating potential for success.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* clinical-pathological diagnosis of NAFLD and current evidence of active disease, which will be determined by the ongoing presence of hepatic steatosis estimated by diffusely echogenic liver via ultrasound suggestive of fatty liver and a serum alanine aminotransferase (ALT) level of 45 U/L or greater.
* age 10 -17 yrs
* overweight or obese (BMI \>75th percentile).

Exclusion Criteria:

* pregnancy
* HbA1c \>7%
* history of parenteral nutrition
* hepatic virus infections (HCV RNA-polymerase chain reaction negative; hepatitis A, B, C, D, E, and G; cytomegalovirus; and Epstein-Barr virus)
* use of medications known to induce steatosis (e.g. valproate, amiodarone, or prednisone), elevate liver enzymes, or affect body weight and carbohydrate metabolism (within the last 6months)
* autoimmune liver disease
* metabolic liver disease
* Wilson's disease
* genetic conditions (e.g. glycogen storage disorder) leading to hepatic steatosis;
* history of bariatric surgery
