Can a 20-Hour fast help your pancreas?
NCT ID NCT05717127
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether intermittent fasting (eating only within a 4-hour window each day) can improve how well the pancreas makes insulin in people with early type 2 diabetes. 51 adults with type 2 diabetes and obesity took part. The goal was to see if this eating pattern could slow the decline in beta-cell function, which is a key cause of diabetes.

Active substance
intermittent fasting (time-restricted feeding with 20 hours fasting and 4-hour eating window)
What this could lead to
If it works, this could point toward a simple lifestyle approach to help preserve insulin production in early type 2 diabetes.
What could go wrong
This is a small, completed study with only 51 participants. Results may not apply to everyone, and the fasting schedule may be hard to maintain long-term.
