Summary
This trial tests whether eating dairy products can improve how the body uses insulin in overweight and obese adults with prediabetes. Participants will be randomly assigned to eat either limited dairy (1 serving or less per day), reduced-fat dairy, or regular-fat dairy for 12 weeks. The study measures changes in insulin sensitivity using a precise test called a hyperinsulinemic-euglycemic clamp, along with other markers of glucose control and heart health.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Dairy products (reduced-fat and regular-fat)
- What this could lead to
- If dairy helps, it could offer a simple dietary strategy to improve insulin sensitivity and potentially delay or prevent type 2 diabetes in people with prediabetes.
- What could go wrong
- This is a small, early-stage trial, and results may not apply to everyone. The effect of dairy on insulin sensitivity is uncertain, and any benefit could be modest.
