NCT ID NCT06053294
First seen Jul 02, 2026 · Last updated Jul 02, 2026
Summary
This study investigates whether the speed at which carbohydrates are digested and absorbed affects how rewarding they feel. Researchers will give healthy adults flavored drinks sweetened with either real sugar or a no-calorie sweetener, then measure changes in brain activity, metabolism, and food preferences. The goal is to understand the gut-brain connection that drives cravings for high-carb foods.
