Summary

Story at-a-glance

Just five minutes of exposure to junk food branding — including ads that did not show any food — caused children to eat an average of 130 more calories that same day
Logos, jingles, and color schemes trigger subconscious food cravings by hijacking children's natural hunger cues, even when the actual food isn't present or referenced in the ad
A UK study found that brand-only ads were just as powerful as food-based ads in increasing caloric intake, with no difference in effect across TV, billboards, podcasts, or social media
Kids who were already overweight were more impacted by the advertising, eating even more calories, showing that these ads compound existing weight struggles rather than just influence new behavior
Although the UK plans to restrict junk food ads before 9pm, public ads like posters and billboards remain legal, leaving children vulnerable to branding triggers proven to increase overeating

0:50.5	Each child participated in two sessions, one featuring high-fat, high, high salt food ads, and another showing only non-food advertising.
