Advisers warn the obesity plan is drifting
Lauren Bowes Byatt, Nesta's director of healthy life, told The Grocer that ministers had not followed through on plans confirmed in December, with an industry-wide consultation expected in the spring.
"Where is the political leadership on this?" she asked. "It's been 464 days since the policy was announced and we're nowhere near it being implemented."
Bowes Byatt, a former Cabinet Office adviser who helped lead the government's response to Covid and other national emergencies, warned that reliance on piecemeal measures would leave the country with poorer health and rising NHS costs. She pointed to more than 700 obesity policies over the past 30 years, during which obesity rates had doubled.
She argued that the government could not achieve its ambition to end the obesity epidemic within a decade without reviving the standard. "Of the measures in the 10 Year Health Plan, there is only one that gets you anywhere near close, and that is the healthy food standard," she said.
Her criticism follows a cross-party Health and Social Care Committee report last week warning that the obesity strategy would fail unless Andy Burnham took personal charge. The committee said it had no faith in ministers to deliver the 10 Year Health Plan, launched in July 2025 under Wes Streeting.
Consultation and regulation remain unresolved
The government's stated timetable leaves implementation dates dependent on consultation. In a June 10, 2026, written parliamentary answer, health minister Baroness Merron said a full public consultation would launch "soon". She said the intention was to finalize the policy and lay legislation so that mandatory reporting would take effect before this Parliament ends, no later than 2029.
The regulator had also yet to be chosen, according to a Food Standards Agency board paper published June 25, 2026. It recorded that then-public health minister Ashley Dalton had formally sought the agency's continued support in December 2025 and identified it as a possible regulator, subject to consultation and a ministerial decision.
At the time of that paper, no funding had been provided and Department of Health and Social Care ministers had not decided which body would regulate the standard.
What Nesta's retailer targets could achieve
Nesta's updated modeling, published July 9, 2026, proposed a sales-weighted average converted nutrient profiling model (cNPM) health target of 69 for the UK's 11 largest grocery retailers. If all 11 reached it, Nesta estimated that adult obesity prevalence in Great Britain would decline by 19% and childhood obesity prevalence by 23%, with annual societal benefits of around £20 billion.
The organization said the sector could meet that target by reformulating products or shifting sales across around 5% of all food products. These are modeled outcomes, conditional on every retailer meeting the proposed target.
Nesta's focus on supermarkets reflects their share of food purchases: its July report said large retailers account for more than 80% of all calories purchased in Great Britain and more than 90% of those bought for consumption at home. On that basis, it described retailer targets as the single biggest opportunity to reduce calorie intake.
Pressure from lawmakers, health groups and businesses
Parliament's Health and Social Care Committee had already called for faster action in its third report on food and weight management, published July 15, 2026. It recommended starting mandatory healthy sales reporting as soon as possible, setting supermarket targets within the following 12 months and extending targets to the wider food industry by the end of Parliament. It also called for the 2018 nutrient profiling model to be implemented no later than the end of 2027.
That report put the annual UK cost of obesity at at least £74.3 billion, including £11.4 billion for the NHS. It said 66% of adults were living with overweight or obesity, while obesity prevalence among reception-age children had reached a record 10.5%.
Health organizations and experts pressed ministers on the consultation timetable in a June 11, 2026, open letter coordinated by the Obesity Health Alliance. Its 65 signatories sought a formal consultation before the summer recess and legislation for the healthy food standard within this Parliament. The letter cited government analysis estimating £36.9 billion in health and economic benefits over 25 years from applying the updated Nutrient Profiling Model.
Food industry leaders have also criticized the delays. Tesco, among the companies backing mandatory health reporting, has described it as one of the most important policies needed to address the challenges facing the UK's food system.
