Summary

This study tests two 2-month programs to help adults with overweight or obesity cut down on ultra-processed foods. One program uses standard diet tips like meal planning, while the other uses a 'dissonance' approach where participants take part in activism against the food industry. The goal is to see if fighting back against junk food makers can make it easier to eat healthier.

What this could mean

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

Active substance
behavioural intervention (educational workshop, dietary change strategies, and cognitive dissonance activism)
What this could lead to
If successful, this could point toward a new, low-cost way to help people eat less ultra-processed food and improve weight management.
What could go wrong
This is a small early-phase trial with only 60 participants, so results may not apply to everyone. The approach is novel and unproven, and it relies on self-reported dietary data.
