Pizza deal ban may slash calories, study suggests

NCT ID NCT07368881

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether removing price promotions (like discounts and bulk deals) from online pizza delivery menus changes what people order and eat. About 600 adults in three UK cities will order a real pizza for their household, with or without promotions. Researchers will track calories ordered and eaten per person to see if removing deals leads to healthier choices.
