Could a special starch help you feel fuller longer?
NCT ID NCT07572513
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how slowly digestible carbohydrates (a type of starch) affect a hormone called GLP-1, which helps control appetite. Researchers will give healthy adults different amounts of raw corn starch and measure their GLP-1 levels, blood sugar, and feelings of fullness over several hours. The goal is to find the best amount of starch to increase fullness and reduce hunger, which could eventually help with weight loss.
