UK government’s obesity plan ‘doomed to fail’, MPs warn

The cross-party health and social care select committee found no convincing evidence that the government’s obesity “moonshot” will achieve significant results. More than a year after the promise was made, basic details remain unclear. These include how success will be measured and how departments will work together.

The committee said responsibility must sit at the top of government. It called for a cabinet committee chaired by the prime minister. This body would coordinate departments, drive delivery, and make obesity a personal priority for the prime minister. The report also wants ministers to explain their plan to parliament within three months.

The warning matters because obesity rates have risen significantly since the 1990s. They have levelled off, but not fallen. The committee says the government needs clear definitions, interim targets, funding details, and separate prevention and treatment plans. Without these changes, it expects the decade-long ambition to fail.

Using standard health definitions, obesity means having excess body fat that can harm health. In adults, body-mass index, or BMI, commonly classifies a BMI of 30 or above as obesity. Being overweight usually means a BMI from 25 to 29.9. BMI is a screening measure, not a complete diagnosis, because it does not directly measure body fat or overall health.

The distinction matters in the article because “overweight” and “obesity” are counted separately but can overlap in wider statistics. The report says 66% of adults are either overweight or living with obesity, while 30% are living with obesity. That means the larger figure includes both groups.

Children are assessed differently from adults. Their healthy ranges vary with age and sex, so adult BMI cut-offs should not be applied directly. The article reports that close to a third of children are overweight or living with obesity, but it does not provide separate percentages for each category.

The figures show that excess weight affects a large share of England’s population. The most recent official statistics cited in the report say 30% of adults are living with obesity. When adults who are overweight are added, the total reaches 66%.

These figures describe different groups, not two totals to add together. The 66% includes people who are overweight and people living with obesity. The article does not give a separate adult percentage for overweight alone. For children, it gives one combined estimate: close to a third are overweight or living with obesity.

The report also places these figures in a longer trend. Adult and child obesity rates have increased significantly since the 1990s. Although the trends have levelled off, there are no signs that rates are falling. This scale is why MPs want measurable goals, prevention, treatment, and coordinated action across government rather than an undefined ambition.

Preventing future obesity means changing conditions that influence people before obesity develops. The report gives unhealthy food as an example, including possible action against advertising and promotions. Treatment is different. It supports adults and children who already have obesity, including through health services and weight-management support.

The key mechanism is focus. Prevention needs population-wide measures, such as healthier food environments and clearer product information. Treatment needs accessible, appropriate support for individuals. If both are placed in one vague programme, officials may not know which department is responsible, what success looks like, or whether resources are reaching people who need treatment.

MPs say this conflation has contributed to muddled thinking and a lack of progress from successive governments. They want a joined-up plan that clearly covers prevention and treatment for adults and children. Separating the goals would make responsibilities, funding, and progress easier to track.

Clear measures turn a broad promise into something that can be tested. The government has promised to “end the obesity epidemic” within a decade, but the report says it has not explained what that means in practical terms. It also has not set out how progress will be measured.

Interim targets would provide checkpoints before the decade ends. MPs could compare results with those markers and question ministers if progress falls behind. A plan would also need to identify responsible departments, planned actions, and funding. Without those details, accountability becomes difficult and problems can remain hidden between announcements.

The likely consequence, according to the committee, is continued inaction or failure. Adult and child obesity rates have risen significantly since the 1990s and have not begun to fall. The report says there are no signs that the current “moonshot” will achieve anything significant. It predicts the ambition is doomed without urgent reassessment.

The government says it has already acted on prevention and treatment. It has restricted junk-food advertising on television before 9pm and online. It has banned volume-price promotions on less healthy food and drink. It has also given councils stronger powers to block new hot-food takeaways near schools.

For people already living with obesity, the government says it is expanding access to weight-management support. This includes NHS weight-loss drugs for people with the greatest clinical need. These measures address both the food environment and individual treatment, though the committee says the overall strategy lacks clarity and coordination.

MPs want stronger action against the food industry. Their proposals include regulating constant unhealthy-food advertising and promotions, simpler product labelling, supermarket targets for selling healthier food, and restrictions on fast-food outlets near schools. They also want a prime-minister-chaired cabinet committee, measurable targets, department responsibilities, and funding details.

Obesity affects more than medical treatment. Food advertising, promotions, product labelling, supermarket sales, and the location of fast-food outlets can shape the environment in which people make choices. Schools and councils also have roles. The article therefore presents obesity as a broad social and public-health challenge.

The mechanism is shared responsibility. Different departments control different parts of prevention, while the NHS and public-health services support people who already have obesity. If these efforts are not coordinated, policies can leave gaps or work against one another. The committee says action must be led from the top because the issue transcends government departments.

The scale reinforces that point. Sixty-six percent of adults are overweight or living with obesity, and close to a third of children are in the same category. The committee wants a cross-government action plan covering departments, actions, funding, prevention, and treatment. It says strong leadership could bring long-term benefits for the NHS, public health, and the economy.
