First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares eating 240 calories of mixed nuts versus pretzels every day for 16 weeks in 56 adults with overweight or obesity. Researchers will measure changes in hunger, blood sugar, insulin, cholesterol, and gut bacteria to understand how nuts affect appetite and weight. The goal is to find out if nuts can help people feel fuller and manage their weight more effectively.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
mixed nuts (almonds, hazelnuts, pecans, pistachios, walnuts, and peanuts)
What this could lead to
If this trial succeeds, it could show that eating a daily portion of mixed nuts helps control appetite and manage weight without strict dieting.
What could go wrong
This is a small, early-stage study with only 56 participants, so results may not apply to everyone. The effects on weight and appetite may be modest or not last long-term.
