About this study
Official title: The Effects of Beta Glucan on Acetate Production and Human Substrate Metabolism
Based on our hypothesis that orally administered resistant starch and beta glucan will be fermented into a SCFA pattern high in acetate and that this will lead to beneficial effects on human substrate and energy metabolism, we aim to address the following primary objective:
To investigate the effects of an acute administration of inulin/beta glucan in combination with resistant starch on fecal and plasma acetate, as well as on fasting and postprandial substrate and energy metabolism in lean normoglycemic men and obese, prediabetic men.
- Conditions
- Pre Diabetes, Obesity
- Being tested
- beta glucan and resistant starch, Placebo, beta gluten
- Medical subject headings
- Glucose Intolerance, Obesity

Questions about this trial
What is this clinical trial studying?
A study testing beta glucan and resistant starch and beta gluten in people with Pre Diabetes and Obesity, run by Maastricht University Medical Center at 1 site in Netherlands.
The full registered description is in the About this study section and the official record.

Where is the study taking place?
The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Plasma acetate concentrations (microM) (time frame: at baseline (before a high-fat mixed meal)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03714646, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Jan 2020; AzTrials last refreshed its copy on 30 Oct 2026.
