NCT ID NCT06118931

First seen Jun 27, 2026 · Last updated Jul 01, 2026 · Updated 2 times

Summary

This study looks at whether the timing of a 9-hour eating window (early, mid, or late in the day) affects blood sugar control in people with obesity who have or are at risk for type 2 diabetes. Over 7 days, 120 participants will follow one of three time-restricted eating schedules while wearing a continuous glucose monitor. The goal is to see if starting the eating window earlier or later makes a difference in average blood sugar levels.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
time-restricted eating (intermittent fasting with a 9-hour eating window)
What this could lead to
If successful, this could show that simply adjusting when you eat (not what you eat) helps control blood sugar, offering a practical lifestyle tool for managing or preventing type 2 diabetes.
What could go wrong
This is a short, early-stage study (7 days) with only 120 participants, so results may not apply to longer-term use or to everyone. It also does not restrict food quality or amount, which could limit blood sugar benefits.
