A different lens
This is about the whole person, the whole story and the systems around them.
Obesity is a complex, chronic and relapsing condition. It is shaped by interacting biological, psychological, social, commercial and environmental factors. For some people, trauma, adversity and prolonged stress are part of that story.
Food or changes in the body can sometimes become ways of coping, surviving or feeling safer. The stress response can also affect sleep, appetite, inflammation, hormones, emotion regulation and metabolism. Later, living in a larger body can bring further harm through judgement, discrimination, unsuitable environments, exclusion and poor healthcare experiences.
We call this the trauma of obesity: the potential for trauma to contribute to obesity, and for the experience of living with obesity, especially in a stigmatising world, to cause or compound trauma.
Important: not everyone living with obesity has experienced trauma, and nobody should have to disclose trauma to receive respectful, compassionate care. A trauma-informed approach is a universal way of making support safer; it is not an assumption or a diagnosis.
​The harm is human clinical and systemic
The 2025 More Than Weight insight work brought together lived experience and workforce perspectives across West Yorkshire, Humber and North Yorkshire. It showed why weight-only responses are not enough.
70%+
of participants experienced social isolation
78%
reported at least one mental health condition
74%
felt misunderstood by healthcare professionals
35%
of professionals felt adequately trained to discuss weight

The bidirectional relationship
​Trauma can shape obesity and obesity can amplify trauma
There is no single pathway and no simple cause. Evidence points to overlapping biological, psychological, behavioural, relational and structural routes that can reinforce one another over time.
Trauma
Obesity
Trauma and adversity can shape obesity
What may be happening beneath the surface
-
Prolonged activation or disruption of stress-response systems.
-
Changes involving sleep, appetite, inflammation, reward and metabolism.
-
Food used for comfort, emotional regulation, protection or survival.
-
Reduced access to safety, supportive relationships, money, time and healthy environments.
-
Mental ill health, medication effects and repeated or cumulative adversity.
Obesity
Trauma and harm
What the world may add to the experience
What may be happening beneath the surface
-
Weight stigma, bullying, discrimination and dehumanising language.
-
Internalised shame, fear of judgement and loss of self-worth.
-
Social exclusion and environments that do not safely fit or include people.
-
Delayed or avoided healthcare after dismissive or painful experiences.
-
Services that repeat stories, withdraw support or measure success only through weight.
What the evidence can and cannot say: studies consistently show associations between childhood maltreatment, chronic stress, weight stigma and obesity-related outcomes. Much of the evidence is observational, so it should inform thoughtful, person-led care rather than be used to presume any individual’s history.
What it means in real life
People do not arrive at services with weight alone
They arrive with lives, strengths, responsibilities, identities, histories and previous experiences of help or harm. The task is not to uncover trauma. It is to avoid adding to it.
“This body saved my life - I ate instead of self-harming.”
Participant voice, More Than Weight insight work, 2025
Being reduced to a number
When BMI becomes the whole story, a person’s health, priorities and context disappear.
Being blamed for surviving
A coping strategy may have made sense in unsafe or overwhelming circumstances. Shame does not create safety or sustainable change.
Having to prove readiness
Rigid thresholds, one-chance pathways and repeated assessments can exclude those facing the greatest barriers.
Avoiding care to avoid harm
Previous judgement, unsuitable equipment or symptoms being attributed only to weight can make returning feel unsafe.
Carrying the stigma inside
Repeated messages about laziness, failure or worth can become internalised and affect mental health, relationships and hope.
Trauma informed response
Change the conversation and the conditions around it
Trauma-informed obesity support does not mean turning every service into trauma therapy. It means recognising the impact of trauma and stigma, responding safely within role, and actively resisting retraumatisation across conversations, services and systems.
01 / Relational
Every interaction matters
-
Ask permission before discussing weight.
-
Listen to what matters before offering advice.
-
Use the person’s preferred language.
-
Offer honest options without pressure or judgement.
-
Never require trauma disclosure.
02 / Organisational
Make services safer to use
-
Provide suitable seating, equipment and privacy.
-
Train and support the whole workforce.
-
Keep routes back open and avoid punitive discharge.
-
Measure dignity, trust, wellbeing and function, not weight alone.
-
Use lived experience as leadership, not decoration.
03 / System
​
Design systems around real lives
-
Connect physical, psychological, social and community support.
-
Address poverty, discrimination and unequal access.
-
Commission for continuity, experience and outcomes.
-
Join prevention, treatment and long-term support.
-
Learn who is excluded, who leaves and where harm occurs.

Our Call to Action
If people feel blamed when they ask for help, the system is not working. We can build something different: support that understands the body, respects the person, recognises the context and does not add further harm.
