NCT ID NCT07674875
First seen Jun 30, 2026 · Last updated Jul 01, 2026 · Updated 1 time
Summary
This trial investigates whether changing how often and when people with type 2 diabetes eat can improve weight, blood sugar, and cholesterol. Over 12 weeks, participants follow one of three eating plans: a standard 6-meal diet, a 3-meal diet, or time-restricted eating (eating all food within an 8-hour window). The study compares these approaches to see which works best for managing diabetes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- dietary intervention (meal frequency and timing)
- What this could lead to
- If successful, this could point toward a simple, non-drug way to help manage type 2 diabetes by adjusting when and how often people eat.
- What could go wrong
- This is a small, 12-week study, so long-term effects are unknown. Results may not apply to everyone, and sticking to the eating plans may be hard for some.
