The U.K. is pulling the plugs on junk food advertisements as part of a stringently enforced health policy. Initiated to curb obesity rates and promote healthier living, this piece of legislation bans junk food advertisements aired before 9 PM, a first of its kind move. This robust decision has garnered global interest, setting a potentially influential precedent for other countries.

In Japan, obesity rates are significantly lower as compared to other developed nations due to prioritizing healthy living. However, the increase in availability of fast food and the resulting shift in dining habits have become a growing concern. Therefore, discussions about the U.K.'s decision to regulate junk food advertising have intensified, with public sentiment favoring Japan's adoption of similar measures.

Unlike in the U.K., the U.S. and EU have looser regulations on junk food advertising. Whilst there are some restrictions aimed at children, there's a larger emphasis on promoting physical activity and awareness campaigns rather than direct regulation. The U.K.'s drastic action has sparked international conversation about the role of advertising in combatting obesity.
