Do Ultra-Processed meals make you eat faster and feel less full?
NCT ID NCT07808892
First seen Sep 09, 2026 · Last updated Sep 10, 2026 · Updated 1 time
Summary
Researchers at Ariel University are studying how the level of food processing and nutritional quality affect how much people eat, how fast they eat, how full they feel, and their blood sugar. Forty adults in Israel with a body mass index between 20 and 40 will eat three laboratory test meals in random order: one low-processing, high-quality meal; one high-processing, high-quality meal; and one high-processing, low-quality meal. The study also explores whether anxiety or food insecurity change these responses, and compares Israeli participants with U.S. participants to see if background diets matter.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Three test meals that differ in processing level and nutritional quality
- What this could lead to
- If processed meals drive people to eat faster and consume more, this could shape dietary advice and future trials on ultra-processed foods.
- What could go wrong
- The study is small, with 40 participants, and measures short-term responses in a lab. Lab meals may not reflect how people eat at home, and the results may not apply to other groups.
