The Association for the Study of Obesity (ASO) has submitted a formal representation to HM Treasury ahead of the Autumn Budget 2025, calling for targeted investment in obesity treatment and prevention as a driver of improved public health, workforce productivity, and economic growth.
The submission highlights that obesity costs the UK an estimated £126 billion each year, including £30.8 billion in lost productivity and £11 billion in direct NHS spending. Without decisive action, annual costs are projected to rise by 10 percent in real terms by 2040.
ASO’s recommendations to the Treasury focus on three key, evidence-based priorities:
-
Expanding access to obesity care through integrated primary and secondary services, ensuring every Integrated Care Board has at least one dedicated multidisciplinary obesity treatment network.
-
Accelerating equitable rollout of new pharmacological treatments, particularly in deprived areas, to reduce health inequalities and deliver measurable fiscal and social returns.
-
Investing in prevention and community-based programmes to address the structural drivers of obesity and secure long-term fiscal sustainability.
The proposals demonstrate how strategic investment can reduce NHS pressures, enhance workforce participation, and narrow regional health inequalities, delivering long-term value for money.
Professor Nicola Heslehurst, President of ASO, said:
“This submission reflects ASO’s evidence-led commitment to improving obesity care and reducing health inequalities. With the right investment, the UK can make real progress in supporting healthier lives and a stronger economy.”
