What this trial studies

This study investigates the impact of a low fructose diet on adolescents diagnosed with non-alcoholic fatty liver disease (NAFLD). It aims to determine how reducing fructose intake can improve liver function and metabolic health in obese youth. Participants will follow a dietary intervention designed to lower their fructose consumption, and the effects on liver health and insulin resistance will be monitored. The study builds on previous findings that link high fructose intake to worsening liver conditions in children.

Who should consider this trial

Good fit: Ideal candidates are obese boys and girls aged 12-18 years with a clinically diagnosed case of NAFLD.

Not a fit: Patients with a history of primary liver disease, Type 2 Diabetes, or those on medications causing hepatic steatosis may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could provide a dietary approach to effectively manage and improve liver health in adolescents with NAFLD.

How similar studies have performed: Previous studies have shown promising results with dietary interventions in managing NAFLD, indicating potential for success in this approach.

Eligibility criteria

Inclusion Criteria:

* obese boys and girls aged 12-18 years (Tanner Stage: III-V) with clinically diagnosed NAFLD

Exclusion Criteria:

1. all patients with a history of a known primary liver disease associated with steatohepatitis (Wilson disease, various metabolic disorders, viral hepatitis) (7);
2. All patients with a known primary diagnosis of Type 2 Diabetes or those on insulin;
3. Patients on medications known to cause hepatic steatosis (e.g., methotrexate, corticosteroids, valproic acid, statins);
4. Patients with evidence of bridging fibrosis (8); and
5. Patients with a known significant history of smoking or alcohol consumption (6, 9) and
6. Any patient undergoing an active weight loss program and/or who has received bariatric surgery for the treatment of obesity
7. Any participant with a cardiac pacemaker or with metal pins as this is a contraindication for MRS/MRI testing
8. Any participant of child bearing potential who is known to be pregnant (as this is a contraindication to MRS/MRI) testing. All females of child bearing potential will be asked to undergo a routine pregnancy test (urine) prior to MRS/MRI testing. This will be conducted in the baseline study visit
9. Any child with significant developmental delay or a significant co-morbidity that precluded the ability to participate in study procedures
