UK MPs target food retailers with turnover fines and ad bans

A cross-party group of British MPs has called for radical market regulation to curb obesity, proposing binding healthy-food sales targets for supermarkets and turnover-based fines for non-compliance. The health select committee’s report to parliament argues that decades of relying on individual willpower have failed, allowing an environment engineered around cheap, unhealthy food to drive obesity rates in England to 30%.

The proposals carry direct consequences for large food retailers, who would be required to report healthy product sales and face binding targets within a year. These mandates would extend to other major food businesses by the end of the current parliament. If companies fail to comply, the committee suggests levying turnover-based fines, with the revenue used to subsidise healthier food choices.

The advertising sector also faces disruption under the plan, which calls for a total ban on outdoor advertising of foods high in fat, salt, and sugar by July 2027. Currently, sweets, chocolate, and crisps attract £196m in annual advertising spend, compared to just £19m for fruit and vegetables. Additionally, the report recommends strengthening council powers to block new fast-food outlets, noting that KFC has successfully challenged local takeaway restrictions more than half the time.

Perhaps the most significant structural shift is the committee’s demand to exclude food businesses that sell a high share of unhealthy products, along with their trade bodies, from shaping food and obesity policy. MPs explicitly compare the food industry to tobacco companies, arguing that industry warnings about "prices, jobs or the economy" have repeatedly delayed or diluted public health measures.

This lobbying exclusion was previously rejected by ministers under Sir Keir Starmer, who warned it would "prevent effective engagement", though MPs are positioning the proposal ahead of Andy Burnham's expected premiership. The economic rationale for intervention rests on the £74bn annual cost of obesity to the UK, including £11bn to the National Health Service alone. Chief medical adviser Chris Whitty noted it is "hardly rocket science" to look at France, which has kept obesity levels steady since 1990, whereas UK rates have continued to climb, particularly among poorer demographics.

The committee also pushed back against relying on new weight-loss drugs to solve the crisis. While off-patent GLP-1 drugs may transform treatment, MPs argue that "treatment is what becomes necessary when prevention has failed," reinforcing their case for upstream market intervention.
