The majority of the UK's population are living with overweight or obesity. Weight management programmes provided by the NHS and local authorities deliver limited outcomes. Health inequities are evident. For example people from the Black communities, people living with learning disabilties, those from the most deprived communities, and men all experience barriers to taking part and poorer outcomes. The use of pharmacotherapy, very low energy diets and bariatric surgery all provide additional benefit to lifestyle change, however very litleis understood about how service users experience these interventions and programmes. Research in this field explores outcomes and experience of people taking part in weight management programmes, as well as clinicians and stakeholders.
