Starting October 2025, the UK will ban junk food advertisements on TV before 9 pm and online at all times. This policy aims to tackle childhood obesity by reducing exposure to unhealthy food marketing. Foods high in sugar, salt, or fat—such as fast food, sugary drinks, and ready meals—will be affected.

Research suggests the move could prevent 20,000 cases of childhood obesity annually, potentially removing over 7 billion calories from children’s diets. By limiting exposure to tempting ads, the government hopes to encourage healthier eating habits among young audiences.

The ban could also push brands to develop healthier recipes, supporting the shift toward better nutrition. With one in ten children in the UK obese and one in five suffering from tooth decay by age five, the health and financial benefits are substantial. The policy is projected to save the NHS £2 billion and improve children’s long-term well-being.
