Overview

  • A randomized trial involving 240 children aged 7–15 found that even five minutes of junk food advertising increased daily calorie intake by 130 calories.
  • Brand-only ads, featuring logos without specific food products, were as effective as product-based ads in driving higher calorie consumption.
  • Children with higher body mass index (BMI) showed greater responsiveness to HFSS advertising, amplifying concerns about its impact on vulnerable groups.
  • The UK government’s upcoming 9pm TV watershed and online HFSS ad restrictions, set for October, are expected to reduce childhood obesity but may exempt brand-only ads.
  • Health experts are urging policymakers to address this regulatory gap, emphasizing that repeated exposure to such ads could lead to significant weight gain over time.
