Slowly Digestible Carbohydrates for GLP-1 Secretion (NCT07572513)
🩺 Plain-English Summary (8th-Grade Level)
The goal of this clinical trail is to learn if the hormone, glucagon-like peptide-1 (GLP-1), is stimulated by slowly digestible carbohydrates (SDCs) in healthy adults. In the current study, researchers will observe the amount of SDC that results in clinically meaningful levels of GLP-1, shown by an increase in feelings of fullness and a decrease in hunger, and how long an elevated level of GLP-1 lasts after starch consumption. Researchers aim to address two questions: What amount of SDC maximizes GLP-1-mediated satiety, and does the impact to satiety continue in a second meal? The overall goal is to maximize ileal-digesting SDC's potential use as a food-based agent for weight loss. Researchers will compare 20, 40, and 60 g of raw corn starch compared to a maltodextrin control on total plasma GLP-1 concentrations, insulin, and blood glucose at baseline and 15, 30, 60, 90, 120, and 180 minutes post-consumption of SDC. Researchers will also measure satiety at baseline, 60, 120, 180 minutes and after a second meal. There will be a total of 4 study visits with a least a 7-day break between visits. At each study visit, participants will: * Consume a randomized test beverage (SDC or maltodextrin) * Receive a blood draw at 7 timepoints over 3 hrs * Take a satiety questionnaire 5 times over 3 hrs * Consume a standardized lunch 3 hrs after the test beverage consumption
