Summary

This study planned to test a fiber-enriched chewing gum (FibreGum) as a way to help with weight management in healthy adults with a BMI between 23 and 40. The goal was to see if people would actually use the gum and find it acceptable, not to measure weight loss directly. However, the study was withdrawn before any participants were enrolled, so no data was collected.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
FibreGum chewing gum (galactooligosaccharides)
What this could lead to
If it had worked, this could have pointed toward a simple, accessible way to support healthy weight management using a fiber-enriched gum.
What could go wrong
The study was withdrawn before enrolling anyone, so no results are available. The approach was only being tested for feasibility, not effectiveness, and any weight loss would likely be modest.
