Summary

This study tests whether intermittent fasting can improve how the body releases insulin in people with prediabetes or early type 2 diabetes. About 200 adults with a BMI between 25 and 40 will follow a 4-week fasting plan or a control diet. The goal is to see if fasting can boost the first burst of insulin after eating, which is often impaired in these conditions.
