Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 and older with impaired glucose regulation and a BMI between 23.0 and 45.0 kg/m2.
✕Probably not a fit
Patients with a confirmed diagnosis of diabetes or those on hypoglycemic treatment will not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This trial evaluates the impact of a Time-Restricted Feeding (TRF) regimen on individuals with impaired glucose regulation compared to those receiving standard care over a 12-month period. Participants will be monitored for changes in glucose levels and overall health outcomes. The study aims to determine if TRF can effectively improve glucose regulation in overweight or obese patients. The intervention involves structured eating windows and reduced calorie intake.
Why it matters
Potential benefit: If successful, this approach could provide a novel dietary strategy to improve glucose regulation and reduce the risk of diabetes in overweight and obese individuals.
How similar studies have gone: Other studies have shown promising results with time-restricted feeding approaches, suggesting potential effectiveness in managing glucose levels.
