What this trial studies

This study evaluates the effects of a special chewing gum containing fibers on body weight, metabolism, and the microbiomes in obese children. Participants will be randomly assigned to receive either the FibreGum or a placebo. The study aims to determine if this intervention can lead to significant improvements in obesity-related health outcomes. Children will also use a monitoring app to track their progress throughout the study.

Who should consider this trial

Good fit: Ideal candidates are obese children with a BMI at or above the 97th percentile who have recently been referred to a weight management clinic.

Not a fit: Patients with recent antibiotic use, pre- or probiotic treatments, or those undergoing other weight management treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could provide a novel, non-invasive method to help manage obesity in children.

How similar studies have performed: While the specific approach of using chewing gum for obesity management is novel, similar studies exploring dietary interventions for obesity have shown promising results.
