Fasting plus fibre: a Gut-Boosting combo?
NCT ID NCT07691736
First seen Jul 09, 2026 · Last updated Jul 10, 2026 · Updated 1 time
Summary
This study explores whether taking a dietary fibre supplement during a 10-day fast can improve gut health and metabolism more than fasting alone. Overweight adults (BMI 25 or higher) will fast at a clinic and then either receive a resistant starch fibre or a placebo. Researchers will measure changes in gut bacteria, blood sugar, and other health markers to see if the combination offers extra benefits.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- maize-derived resistant starch type IV (dietary fibre)
- What this could lead to
- If successful, this could point toward a simple way to enhance the metabolic benefits of fasting by adding fibre, potentially improving gut health and blood sugar control.
- What could go wrong
- This is an early proof-of-concept study with a small number of participants, so results may not apply broadly. The fibre supplement may cause digestive discomfort, and the fasting protocol is intensive.
