Obesity rates in England have experienced significant growth since 1993, with the proportion of adults aged 16 and over classified as obese rising from 15% to 30% in 2024, according to analysis by the King’s Fund. This increase translates to approximately seven million additional adults living with obesity compared to if rates had remained at 1993 levels. The rise has been particularly pronounced among younger demographics, with 18% of those aged 16 to 24 classified as obese or severely obese in 2024, compared with 6% in 1993.
Multiple structural and economic factors have contributed to the rise in obesity rates. The shift from manual labor to sedentary office work in the service sector has reduced physical activity levels among the general population. Food prices have declined since the 1990s due to increased supermarket competition and the proliferation of fast food outlets and delivery services, making high-calorie foods more accessible and affordable. These economic changes have been compounded by recent cost-of-living crises, during which less healthy foods remained cheaper alternatives to nutritious options. Takeaway establishments serving high-fat, high-salt, and high-sugar foods have become increasingly prevalent, particularly in areas of higher deprivation.
Governments have implemented various policy measures over the past three decades, though public health experts argue progress has been insufficient. These interventions have included advertising restrictions, taxation on sugary beverages introduced in 2018, and most recently a ban on junk food advertising before 21:00 on television and at any time online implemented in January this year. Additional measures targeting fast food outlet locations and unhealthy food promotions remain pending implementation.
Obesity and being overweight impose substantial costs on the UK economy, estimated at approximately £126 billion annually, including £12 billion to the NHS. The condition serves as a risk factor for multiple chronic diseases including type 2 diabetes, heart disease, high blood pressure, osteoarthritis, and certain cancers. Weight loss medications including GLP1-based treatments have become increasingly available both through NHS prescription for eligible patients and through private channels, though public health officials have cautioned against relying solely on pharmaceutical interventions as a long-term solution.
