Reducing Obesity and Closing the Health Gap

The ambition for North West (NW) London is that by 2030, we will stop the rise in obesity and set it on a long-term path to reductionstarting where need and inequality are greatest.

Why this matters 

Obesity affects more than 550,000 people in NW London, including around 60,000 with the most severe forms. It contributes to a wide range of long-term health conditions, affects a person’s quality of life and is closely linked to some of the deepest health inequalities across our communities.  

The impact is felt across all stages of life with around one-third of children and young people also estimated to be overweight or obese. The rate of obesity is higher among older adults, women, people from Black and Asian ethnic groups, people living in more deprived communities, and those with severe mental illness or learning disabilities.  

It is a complex challenge. Residents and partners tell us the same story, that obesity is not just about individual choices. It is shaped by a combination of factors including the food that they can access, the places where they live, income, education, culture, mental health and the support services available. These factors interact in different ways throughout a person’s lifetime, shaping both the risk and the ability to access support. 

What we heard 

Through our conversations with residents, clinicians, local authorities, community organisations, and researchers across health and care, local government, academia, industry, and the VCSE sector, we heard that: 

  • Obesity is shaped by a web of interconnected factors, rather than a single cause 
  • People describe the challenge as going far beyond individual choices 
  • Prevention, access to services, treatment, mental wellbeing, community support and wider social factors all play a role. 

Our approach 

As obesity is shaped by many interconnected factors, no single intervention will be enough. Our mission takes a portfolio approach, supporting action across prevention, access to services and treatment. Progress in one area depends on progress in another. 

We are focusing on three priority areas where residents and partners believe we can make the strongest impact. They reflect where our partners believe innovation, collaboration and collective action have the greatest potential to improve outcomes and reduce inequalities across NW London. 

Strengthening the system and engaging communities

Through all our activities we will strengthen our local system’s ability to collaborate and create change, enable staff to deliver quality care and ensure our work reaches the communities most in need of proactive intervention. For example, our clinical partners serve the NWL community through our CVD Champions Programme. Learn more about the programme here.

Priority area 1: Supporting children and families

Residents and partners told us that early support, focusing on prevention for children and families offers the greatest long-term impact.  This is in recognition of the fact thar habits form early and benefits can compound across the life course and across generations. Childhood obesity rates rise sharply between Reception and Year 6, with families often struggling to find practical help, free from stigma. This makes early years, primary school and the wider family environment critical points for intervention.  

There are key opportunities to:  

  • Strengthen a more joined-up family approach across schools, child health hubs, children’s centres, family services and community organisations.  
  • Improve how families are identified and supported earlier. 
  • Reduce stigma in how support is framed, and make support more practical for families facing poverty, time pressure, digital exclusion or cultural barriers.  
  • Build on existing assets such as family-based programmes, schools and community organisations, while filling gaps for underserved groups, including secondary school-age children and families with complex needs. 

By focusing here, the mission can support a shift from fragmented, reactive support to earlier, more universal and family-centred prevention.  

Priority area 2: Improving equity in access to weight management services

Both residents and partners across the system identified a major gap between the support that exists and people’s ability to find, access and stay engaged with it. Residents described NHS weight management services as low-profile, fragmented and difficult to navigate, with GP gatekeeping, inconsistent referrals, long waits and postcode variation all acting as barriers.  

Partners working across health and care services echoed this, pointing to patchy Tier 2 and Tier 3 provision, oversubscription, and a lack of clarity across boroughs and services. 

There are key opportunities to: 

  • Not just expand activity but make existing pathways easier to access, more equitable and more engaging for people who need them most.  
  • Include clearer referral routes, self-referral or digital front door models 
  • Create more culturally and linguistically tailored support. 
  • Strengthen continuity through coaching, community outreach and better exit routes after time-limited programmes.  

Residents saw this as a practical ‘quick win’, because services often work when people are able to engage with them, but too many people never reach the right support or drop out before they benefit. 

Focusing on access and engagement also helps turn ambition into real system change. By making services easier to use and access and improving the experience for underserved communities, NW London can help more people benefit from the support already available. Increasing the reach and effectiveness of current services can lead to more people achieving sustainable weight loss and maintain a healthy weight, while ensuring efforts are focused where need and inequality are greatest.

Priority area 3: Access to GLP-1s with wraparound care

GLP-1s are one of the most significant recent developments in obesity care, but access is restricted, uneven and often disconnected from wider support needed for long-term success. Partners highlighted the potential of GLP-1s to prevent longer-term conditions and improve outcomes for people at highest risk, while residents recognised their effectiveness but were clear that medicines alone are not enough. Across both groups, the consistent message was that any expansion in access must be paired with education, behavioural support and a clear pathway before, during and after treatment. 

There are key opportunities to:  

  • Develop a more equitable and clinically meaningful model of access that goes beyond the current narrow rollout and links medicines to wider system goals.  
  • Target people with obesity who are at highest risk of long-term conditions and improve how services identify and support these groups. 
  • Develop stronger wraparound support so people are less likely to regain weight, struggle with nutrition or experience fragmented care. 
  • Respond to rapid market change, including growth of private prescribing, testing more joined-up approaches to improve safety, understanding and continuity of care. 

This area has not been chosen as a stand-alone solution, but as one part of the wider portfolio. The mission’s role is to ensure GLP-1s are used where they add genuine value, without crowding out prevention or reinforcing inequality. Done well, this priority could help NW London prepare for the future of obesity treatment while demonstrating how innovation can be linked to better outcomes, better experience and more equitable access. 

Why this is important

Capture the family, as a group, and capture the child early before they get to the stage of being overweight.

 

Resident deliberation – supporting children, families and wider prevention

We need to meet people where they are and empower and support our residents, avoiding any drift into the approach feeling like ‘blame’.

Stakeholder panel – supporting children, families and wider prevention

Biggest gripe is amount of friction in the referral process and how difficult we make it for a patient to join an NHS free programme.

Resident deliberation – equitable access to weight management services

I didn’t even see anyone [to get GLP-1s]. There were no prescription, referral or questions.

Get involved 

Tackling obesity requires collective action. As the mission progresses, we want to continue bringing partners together to share insight, test new ideas and identify opportunities for collaboration.
