Racial disparities in obesity treatment represent a critical health equity issue across the UK, where individuals from ethnic minority backgrounds face both higher rates of obesity-related complications and significant barriers to accessing evidence-based care. Black African, Black Caribbean, South Asian, and other minority ethnic communities experience disproportionate obstacles in receiving timely, culturally appropriate obesity management services, despite often facing greater metabolic risks at lower body mass index thresholds. This article examines the evidence of unequal access to weight management interventions, explores the complex barriers affecting ethnic minority populations, and outlines practical strategies for healthcare professionals and patients to improve equity in obesity treatment and prevention.
Summary: Ethnic minority populations in the UK experience significant racial disparities in obesity treatment, facing both higher metabolic risks at lower BMI thresholds and reduced access to specialist weight management services, bariatric surgery, and anti-obesity medications.
- NICE recommends lower BMI thresholds (23 kg/m² for increased risk, 27.5 kg/m² for high risk) for South Asian, Chinese, Black African, and African-Caribbean populations when assessing obesity-related health risks.
- National audits reveal ethnic minorities are underrepresented in bariatric surgery programmes and tier 3 specialist weight management services, despite higher rates of severe obesity and complications.
- Barriers include socioeconomic disadvantage, language difficulties, cultural beliefs about body weight, inconsistent interpreter provision, and implicit bias within healthcare systems.
- Culturally tailored interventions must accommodate traditional eating patterns, religious observances such as Ramadan, family dynamics, and culturally appropriate physical activity options.
- NHS England's Core20PLUS5 framework and the Health and Care Act 2022 place statutory duties on integrated care systems to monitor obesity service utilisation by ethnicity and reduce health inequalities.
- Patients should discuss weight concerns with their GP, request culturally appropriate support, and only obtain weight-loss medicines through NHS or regulated healthcare services.

Understanding Ethnic Disparities in Obesity Treatment
Ethnic disparities in obesity treatment represent a significant public health concern in the UK, where individuals from ethnic minority backgrounds experience both higher rates of obesity-related complications and reduced access to evidence-based interventions. Research consistently demonstrates that people from Black African, Black Caribbean, South Asian, Chinese, and other minority ethnic communities face disproportionate barriers to receiving timely, culturally appropriate obesity management services.
Obesity prevalence varies considerably across ethnic groups in the UK. Data from the Office for Health Improvement and Disparities (OHID) and the Health Survey for England indicates that Black African and Black Caribbean women experience higher rates of obesity compared to the general population, whilst South Asian populations develop metabolic complications such as type 2 diabetes at lower body mass index (BMI) thresholds than white European populations. People from several minority ethnic groups—including South Asian, Chinese, Black African, and African-Caribbean backgrounds—face higher cardiometabolic risk at lower BMI levels, necessitating ethnicity-specific risk assessment and earlier intervention thresholds. NICE guidance (PH46) recommends using lower BMI cut-offs (23 kg/m² for increased risk, 27.5 kg/m² for high risk) for people from these groups when assessing risk, and NICE CG189 applies ethnicity-adjusted thresholds when considering treatment options including bariatric surgery.
Despite these elevated risks, ethnic minority populations are underrepresented in specialist weight management services, bariatric surgery programmes, and clinical trials for obesity medications. This treatment gap reflects complex, intersecting factors including socioeconomic disadvantage, systemic healthcare inequalities, cultural beliefs about body weight, language barriers, and implicit bias within healthcare systems. Understanding these disparities is essential for developing equitable, effective obesity treatment pathways that serve all communities.
Key considerations include:
-
Recognition that obesity risk and complications vary by ethnicity
-
Application of ethnicity-specific BMI thresholds for risk assessment and intervention
-
Acknowledgement of systemic barriers affecting treatment access
-
Need for culturally tailored approaches to obesity management
Evidence of Unequal Access to Obesity Services in the UK
Substantial evidence documents inequitable access to obesity treatment services across ethnic groups in the UK. National audits of bariatric surgery provision, including data from the National Bariatric Surgery Registry (NBSR) and Getting It Right First Time (GIRFT) reports, reveal that ethnic minorities are underrepresented among patients receiving surgical interventions, despite experiencing higher rates of severe obesity and related comorbidities. Analysis of NHS England data indicates that white patients are more likely to be referred for and receive bariatric surgery compared to patients from ethnic minority backgrounds, even after adjusting for clinical eligibility criteria.
Access to tier 3 specialist weight management services—multidisciplinary programmes offering dietary, psychological, and physical activity support—similarly shows ethnic disparities. Evidence examining referral patterns suggests that general practitioners may be less likely to refer patients from ethnic minority backgrounds to these services, potentially due to assumptions about patient preferences, language barriers, or unconscious bias. Once referred, ethnic minority patients may demonstrate lower attendance rates and higher dropout rates from weight management programmes, suggesting that current service models may not adequately meet diverse community needs.
The prescription of anti-obesity medications, including newer agents such as semaglutide (Wegovy) and liraglutide (Saxenda), may also exhibit ethnic inequalities. These medicines are initiated via specialist weight management services under NICE technology appraisals (TA875 for semaglutide, TA664 for liraglutide) with specific eligibility criteria and duration limits. Emerging evidence suggests that patients from ethnic minority backgrounds may be less likely to access pharmacological obesity treatment, despite clinical eligibility. This disparity may reflect multiple factors including healthcare professional awareness of ethnicity-specific risk thresholds, patient-clinician communication challenges, and differential treatment-seeking behaviours. National prescribing datasets often do not capture ethnicity, and local audits are needed to fully understand these patterns.
Evidence of access disparities includes:
-
Underrepresentation in bariatric surgery programmes
-
Lower referral rates to specialist weight management services
-
Potential reduced access to anti-obesity medications
-
Higher dropout rates from existing treatment programmes
These documented inequalities highlight the urgent need for system-level interventions to ensure equitable obesity treatment access across all ethnic communities in the UK.
Barriers to Effective Obesity Treatment for Ethnic Minorities
Multiple, interconnected barriers impede effective obesity treatment for ethnic minority populations in the UK. Socioeconomic factors play a fundamental role, as ethnic minorities are disproportionately affected by poverty, unemployment, and housing insecurity—all of which are associated with higher obesity rates and reduced healthcare access. Financial constraints may limit ability to afford healthy foods, gym memberships, or time off work for medical appointments, creating practical obstacles to weight management. Transport barriers and digital exclusion can further limit access to services.
Language and communication barriers significantly affect healthcare engagement. Patients with limited English proficiency may struggle to understand treatment recommendations, navigate complex healthcare systems, or effectively communicate their concerns to clinicians. The NHS Accessible Information Standard (SCCI1605) mandates provision of communication support, including interpreter services, but implementation is inconsistent. Important nuances regarding dietary habits, cultural practices, and health beliefs may be lost in translation. Written patient information materials are often unavailable in community languages, further limiting accessibility.
Cultural beliefs and stigma surrounding obesity vary across communities and may influence treatment-seeking behaviour. In some cultures, larger body sizes may be viewed more positively or associated with prosperity and health, potentially reducing perceived need for intervention. Conversely, weight-related stigma and shame may prevent individuals from seeking help. Mental health concerns, including depression and anxiety—which are both risk factors for obesity and potential barriers to treatment engagement—may be particularly stigmatised in certain communities, discouraging disclosure and comprehensive care.
Systemic healthcare factors including implicit bias, lack of cultural competency among healthcare professionals, and inflexible service delivery models contribute to treatment disparities. Appointment times may conflict with religious observances or work patterns common in certain communities. Dietary advice may fail to account for traditional eating patterns, making recommendations feel irrelevant or impractical. Workforce diversity and culturally competent care remain areas requiring improvement.
Structural barriers include:
-
Limited availability of culturally appropriate services
-
Insufficient ethnic diversity among healthcare staff
-
Lack of community-based intervention programmes
-
Inadequate consideration of religious and cultural practices in treatment design
-
Inconsistent application of the NHS Accessible Information Standard
Cultural Considerations in Obesity Management
Effective obesity management for diverse populations requires culturally sensitive approaches that respect and incorporate patients' cultural backgrounds, beliefs, and practices. Dietary interventions must be tailored to accommodate traditional eating patterns rather than imposing generic Western dietary models. The British Dietetic Association (BDA) provides culturally tailored nutrition resources to support this approach. For example, South Asian diets rich in rice, chapatis, and traditional curries can be modified to reduce calorie density whilst maintaining cultural authenticity—such as using cooking spray instead of ghee, increasing vegetable portions, and choosing wholegrain alternatives. Similarly, Caribbean diets can be adapted by modifying preparation methods for traditional foods whilst preserving cultural food preferences.
Religious observances significantly influence eating patterns and must be considered in treatment planning. Ramadan fasting presents particular considerations for Muslim patients, as the month-long practice of daytime fasting followed by evening meals can affect weight management efforts. Healthcare professionals should provide guidance on maintaining healthy eating patterns during Ramadan, including balanced iftar and suhoor meals, adequate hydration, and appropriate timing of physical activity. For patients taking obesity medications, consultation regarding medication timing during fasting periods is essential. Resources from the British Islamic Medical Association (BIMA) and Diabetes UK provide evidence-based Ramadan guidance. Patients must not alter medication doses without consulting their clinician or pharmacist.
Physical activity recommendations should acknowledge cultural norms regarding exercise, particularly for women from communities where gym attendance or outdoor exercise may be culturally inappropriate or uncomfortable. Alternative approaches might include home-based exercise programmes, women-only exercise sessions, or activities that align with cultural practices such as traditional dance forms. Consideration of modest dress requirements and same-gender exercise environments can improve participation.
Family and community dynamics play crucial roles in many ethnic minority cultures, where food preparation and consumption are often communal activities. Successful interventions should involve family members in treatment planning and education, recognising that dietary changes affect entire households. Community-based approaches, including partnerships with faith organisations, community centres, and ethnic minority health advocacy groups, can enhance programme reach and cultural acceptability. Person-centred assessments are essential to avoid stereotyping and ensure care reflects individual circumstances.
Healthcare professionals should:
-
Conduct culturally sensitive assessments of dietary habits and physical activity
-
Provide patient information materials in appropriate languages and formats (NHS Accessible Information Standard)
-
Utilise trained interpreters when needed
-
Demonstrate respect for religious and cultural practices
-
Involve family members in treatment discussions when appropriate and with patient consent
Improving Equity in Obesity Treatment and Prevention
Addressing ethnic disparities in obesity treatment requires comprehensive, multi-level interventions targeting healthcare systems, clinical practice, and community engagement. Healthcare system reforms should prioritise equitable access through targeted outreach to underserved communities, removal of administrative barriers, and investment in culturally adapted weight management services. NHS England's Core20PLUS5 framework and the Health and Care Act 2022 place statutory duties on integrated care systems (ICSs) to reduce health inequalities. ICSs should monitor obesity service utilisation by ethnicity, setting explicit targets for reducing disparities and holding services accountable for equitable provision. Routine ethnicity data capture in healthcare records is essential for monitoring and audit.
Clinical practice improvements must include mandatory cultural competency training for healthcare professionals involved in obesity management. This training should address implicit bias, enhance understanding of ethnicity-specific obesity risks, and develop skills for delivering culturally sensitive care. Application of appropriate BMI thresholds for different ethnic groups, as recommended by NICE PH46 and CG189, should be systematically implemented in primary care and specialist services. When considering pharmacological treatment, clinicians should refer to NICE technology appraisals: TA875 for semaglutide (Wegovy) and TA664 for liraglutide (Saxenda), which specify eligibility criteria, specialist service initiation, and duration limits. For bariatric surgery, NICE CG189 provides ethnicity-adjusted BMI thresholds. Clinical guidelines should explicitly address ethnic disparities and provide practical guidance for tailoring interventions to diverse populations.
Community-based prevention programmes offer promising approaches for reducing obesity disparities. Partnerships with community organisations, faith groups, and ethnic minority health networks can facilitate culturally appropriate health promotion activities, peer support programmes, and early intervention initiatives. Successful examples include community cooking classes featuring healthy adaptations of traditional recipes, culturally tailored exercise programmes, and peer-led weight management groups conducted in community languages.
Research and data collection must improve to better understand and address ethnic disparities. Clinical trials of obesity interventions should ensure adequate representation of ethnic minority populations, and routine healthcare data should consistently record ethnicity to enable monitoring of treatment access and outcomes. Qualitative research exploring patient experiences and preferences can inform service design.
Policy interventions addressing upstream determinants of obesity—including poverty, food insecurity, and neighbourhood environments—are essential for reducing ethnic health inequalities. This includes ensuring access to affordable healthy foods in areas with high ethnic minority populations, creating safe spaces for physical activity, and addressing employment and housing inequalities that contribute to obesity risk.
Patients from ethnic minority backgrounds should:
-
Discuss weight concerns with their GP, requesting referral to specialist services if appropriate
-
Ask about culturally appropriate dietary advice and support services
-
Enquire about interpreter services and accessible information formats if language or communication is a barrier
-
Seek support from community organisations offering health programmes
-
Only obtain weight-loss medicines through NHS or regulated healthcare services; do not purchase online
When to contact your GP:
-
If you have concerns about your weight and associated health risks
-
If you experience barriers to accessing obesity treatment services
-
If you require support managing weight alongside cultural or religious practices
-
If you develop symptoms that may indicate type 2 diabetes, such as increased thirst, passing urine more frequently (especially at night), unexplained weight loss, fatigue, blurred vision, or slow-healing wounds
-
If you experience joint pain, breathlessness on exertion, or other symptoms affecting daily life
When to seek urgent help:
-
Call 999 if you experience severe chest pain, severe difficulty breathing, or sudden collapse
-
Contact NHS 111 for urgent advice if you have concerning symptoms that cannot wait for a routine GP appointment
Achieving equity in obesity treatment requires sustained commitment from healthcare systems, policymakers, and communities to dismantle barriers and ensure that all individuals, regardless of ethnic background, receive effective, respectful, and culturally appropriate care.
Frequently Asked Questions
Why do racial disparities in obesity treatment exist in the UK?
Racial disparities in obesity treatment arise from multiple interconnected factors including socioeconomic disadvantage, language and communication barriers, cultural beliefs about body weight, inconsistent provision of interpreter services, and implicit bias within healthcare systems. These barriers result in ethnic minority populations being underrepresented in specialist weight management services, bariatric surgery programmes, and clinical trials, despite experiencing higher metabolic risks and obesity-related complications at lower BMI thresholds than white European populations.
What BMI thresholds should be used for South Asian and Black populations when assessing obesity risk?
NICE guidance (PH46) recommends using lower BMI cut-offs for people from South Asian, Chinese, Black African, and African-Caribbean backgrounds: 23 kg/m² indicates increased risk and 27.5 kg/m² indicates high risk, compared to standard thresholds of 25 kg/m² and 30 kg/m² respectively. These ethnicity-specific thresholds reflect the fact that these populations develop cardiometabolic complications such as type 2 diabetes at lower body mass index levels, necessitating earlier risk assessment and intervention.
Can I get weight-loss injections like semaglutide if I'm from an ethnic minority background?
Yes, anti-obesity medications including semaglutide (Wegovy) and liraglutide (Saxenda) are available through NHS specialist weight management services for patients who meet NICE eligibility criteria, which apply ethnicity-adjusted BMI thresholds for certain populations. However, emerging evidence suggests patients from ethnic minority backgrounds may face barriers to accessing these treatments despite clinical eligibility, highlighting the need to discuss weight concerns with your GP and request referral to specialist services if appropriate.
How can I manage my weight during Ramadan whilst following medical advice?
Managing weight during Ramadan requires planning balanced iftar and suhoor meals, maintaining adequate hydration during non-fasting hours, and timing physical activity appropriately. If you take obesity medications, consult your clinician or pharmacist before Ramadan regarding medication timing during fasting periods—never alter doses without professional guidance. Resources from the British Islamic Medical Association and Diabetes UK provide evidence-based Ramadan guidance for patients managing weight and metabolic conditions.
What should I do if language barriers are preventing me from accessing obesity treatment?
The NHS Accessible Information Standard (SCCI1605) mandates provision of communication support including interpreter services for patients with limited English proficiency, and you have the right to request these services when accessing obesity treatment. Contact your GP practice or specialist service to arrange a trained interpreter for appointments, and ask whether patient information materials are available in your preferred language or format to ensure you fully understand treatment recommendations and can communicate your concerns effectively.
Are there weight management programmes that respect my cultural food traditions?
Yes, culturally tailored weight management approaches can accommodate traditional eating patterns from South Asian, Caribbean, African, and other cuisines whilst supporting healthy weight loss. The British Dietetic Association provides culturally adapted nutrition resources, and many community organisations partner with NHS services to offer programmes featuring healthy adaptations of traditional recipes, culturally appropriate physical activity options, and peer support in community languages. Ask your GP about locally available culturally sensitive services or request referral to a dietitian experienced in working with diverse populations.
