A new study published in the journal Computers in Human Behavior found that people trying to overcome cravings for unhealthy foods use content featuring high-calorie dishes on social media as a substitute for actual meals.
The study was conducted by researchers from the University of Bristol, together with colleagues from the University at Buffalo. A total of 840 people aged 19 to 77 participated in three experiments.
It was found that dieters spent 30% more time watching high-calorie content than non-dieters. However, when offered real food, they ate significantly less.
Scientists explain this effect through the concept of "cross-modal satiation." Stimulating one sense—vision—can reduce the desire to engage another, taste.
Study leader Esther Kahn noted that in a digital environment where gastronomic content is widely accessible, such visual interaction could be a simple way to support dietary goals.
