The ban on pre-9pm TV ads for HFSS (high in fat, salt or sugar) products being considered by the Government would not play a constructive or quantifiable role in reversing the UK’s rising childhood obesity rates. 

The ban on HFSS product ads since 2008 around children’s programming has not impeded the inexorable rise of childhood obesity. In 2010, Ofcom termed an HFSS watershed ban ‘disproportionate’ and ‘ineffective’. 

In 2018, a watershed ban would be even less effective. Children’s linear broadcast TV viewing is down by half since 2010, mainly to YouTube’s advantage, which benefits from light-touch HFSS regulation.
