An interventional study of Concord Grape Juice and Low flavonoid low essence beverage in Glycemic Response and Appetitive Behavior, sponsored by Purdue University. Completed at 1 site in United States. Open to participants aged 25 Years to 60 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2020-11-05.
Sponsored by Purdue University · Not applicable, Interventional, and Basic science
Assess the impact of 100% grape juice with a meal on postprandial glycemic response and subsequent appetite, food intake and cognitive function.
Investigators earlier studies and published literature suggest that the phenolic content and strong flavor intensity of 100% Concord grape juice hold potential beneficial effects on blood sugar levels. Investigators aim to better understand the consumption of 100% grape juice with a meal modifies appetite and glycemia acutely and over the day using a 24 hour glucose monitor.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Ran from May 2019 to primary completion in Oct 2019, 5 months.
Of 75 non-industry interventional studies with no phase under Appetitive Behavior, half reached primary completion within 7 months of starting (the median), counting those still running; a quarter within 3 and three quarters within 16. This study's 5 months is below that.
Counting every sponsor, half of 76 studies reached it within 7 months; a quarter within 3 and three quarters within 16.
