Pre-Fast power meal: oats and yogurt may tame hunger and glucose
NCT ID NCT07447505
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether eating a high-protein, high-fiber meal (oats, Greek yogurt, peanut butter, cranberries, almonds) before a fast helps people feel fuller and keeps blood sugar stable during fasting hours. Thirty-eight healthy adults will try both the special meal and a low-protein, low-fiber meal on separate days. Researchers will track appetite and glucose levels using continuous monitors.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- High-protein, high-fiber meal (oats, Greek yogurt, peanut butter, dried cranberries, almonds)
- What this could lead to
- If it works, this could point toward simple dietary strategies to manage hunger and blood sugar during fasting.
- What could go wrong
- This is a small, early-stage study in healthy adults, so results may not apply to people with medical conditions. The effect may be modest or not meaningful in real-world settings.
