Summary

This study tests whether giving people different taste-based advice helps them reduce their free sugar intake to less than 5% of daily energy. Participants are adults in southern England who consume more than 10% of their energy from free sugars. They are randomly assigned to advice that either replaces sugary foods with sweet low-sugar options or with non-sweet flavorful foods, and their sugar intake, weight, and waist size are tracked.

What this could mean

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

Active substance
dietary advice (sweet or non-sweet replacements)
What this could lead to
If successful, this could offer practical, taste-based strategies to help people reduce free sugar intake and improve diet quality.
What could go wrong
This is a small, early-stage behavioral trial. Results may not apply to all populations, and adherence to dietary advice may vary.
