Carb counting could curb prediabetes progression
NCT ID NCT07525622
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether teaching basic carbohydrate counting can lower blood sugar levels in people with prediabetes. About 120 adults with prediabetes will either get standard lifestyle advice or extra training on counting carbs. Researchers will check HbA1c levels at 3 and 6 months to see if the education helps prevent progression to type 2 diabetes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- carbohydrate counting education
- What this could lead to
- If it works, this could provide a simple, scalable dietary strategy to prevent or delay type 2 diabetes in people with prediabetes.
- What could go wrong
- This is a small, early-stage trial (120 participants) testing a behavioral intervention, so results may not be generalizable. Dietary changes can be hard to maintain long-term.
