This piece discusses eating disorders, disordered eating, and neurodivergence.
It is written from lived experience and research, not as medical advice.
If you are struggling with food or your relationship with your body, you deserve support, and you are not alone.

Eating Disorders and AuDHD: What’s Really Going On

Eating disorders are significantly more common in autistic and ADHD people; and even more so in those with both (AuDHD).
This isn’t coincidence, vanity, or a lack of self-control.
It is about nervous systems, sensory processing, dopamine, and survival strategies.

1. It often starts with regulation, not body image

For many AuDHD people, food is not just food. It is:

• sensory input

• predictability

• control

• stimulation or relief

Restricting, bingeing, eating the same foods, or avoiding food entirely can all be ways of regulating an overwhelmed nervous system.

Body image may be part of the picture. But it is rarely the root.

2. Sensory processing plays a huge role

Autistic sensory differences can make:

• textures unbearable

• smells overwhelming

• temperatures distressing

• mixed foods intolerable

This can lead to:

• very limited “safe foods”

• skipping meals

• anxiety around eating socially

• shame when needs aren’t understood

What looks like “picky eating” from the outside may actually be sensory avoidance necessary for coping.

3. ADHD and dopamine complicate hunger cues

ADHD affects:

• interoception (not noticing hunger or fullness)

• impulse regulation

• dopamine-seeking behaviour

This can result in:

•forgetting to eat

• eating only when energy crashes

• binge–restrict cycles

• eating for stimulation rather than hunger

When autism and ADHD coexist, these patterns can pull in opposite directions, creating chaos around food.

4. Control becomes safety

Many AuDHD people grow up feeling:

• misunderstood

• out of step

• chronically corrected

Food can become one of the only areas of perceived control.
Restricting or rigid eating patterns may feel like:

• stability

• certainty

• something that can’t be taken away

This is not about willpower.
It is about safety.

5. Masking increases risk

Years of masking can disconnect people from:

• bodily cues

• hunger signals

• emotional needs

By adulthood, many AuDHD people no longer trust their bodies, or feel entitled to listen to them.
Eating disorders can grow quietly in that gap.

6. Traditional ED treatment often misses AuDHD needs

Standard approaches frequently:

• ignore sensory issues

• focus heavily on weight and appearance

• rely on group settings and verbal processing

• push “normal eating” without adaptations

Without recognising neurodivergence, treatment can feel unsafe, and ineffective.

7. Recovery looks different for AuDHD people

Recovery may include:

• safe foods being respected

• flexible structure, not rigid plans

• sensory accommodations

• rebuilding interoception slowly

• focusing on regulation before nutrition perfection

Progress is not linear, and it does not have to look “typical” to be valid.

A final note

Eating disorders in AuDHD people are not failures.
They are adaptations. Often formed early, quietly, and for good reason.

Understanding this isn’t about excusing harm. It’s about offering the right kind of compassion, care, and support.



• Research consistently shows a higher prevalence of eating disorders in autistic people, particularly anorexia and ARFID.
Studies by institutions such as King’s College London and the National Autistic Society (UK) highlight overlaps in rigidity, sensory sensitivity, and need for control.

• The term ARFID (Avoidant/Restrictive Food Intake Disorder) is now widely recognised as strongly linked to autism due to sensory processing differences and anxiety around eating.

ADHD, Dopamine, and Eating

• ADHD affects dopamine regulation, which plays a role in appetite, impulse control, and reward-seeking behaviour.
This can lead to irregular eating patterns, binge–restrict cycles, or forgetting to eat entirely.

• ADHD also impacts interoception — the ability to notice hunger and fullness cues — which can make eating feel confusing or disconnected.

AuDHD (Autism + ADHD)

• Emerging research and lived-experience literature suggest that people with both autism and ADHD (AuDHD) experience unique challenges, including:

○ competing needs for routine vs stimulation

○higher rates of burnout

○ increased vulnerability to disordered eating

• While AuDHD is not yet a standalone diagnostic category, it is increasingly recognised by clinicians and researchers as a distinct lived experience.

Masking and Nervous System Stress

• Long-term masking has been linked to:

○ increased anxiety and depression

○ disconnection from bodily signals

○ higher rates of eating disorders and self-harm

• This is supported by autistic-led research and advocacy groups, including Autistic Women & Nonbinary Network (AWN) and UK-based autistic researchers.

Why Traditional ED Treatment Often Fails Neurodivergent People

• Standard eating disorder treatments often:

○ prioritise weight restoration over sensory safety

○ rely heavily on group therapy and verbal processing

○ dismiss sensory-based food needs as “avoidance”

• Neurodivergent-affirming clinicians advocate for adapted approaches that centre regulation, predictability, and autonomy.

Helpful Organisations & Resources

• National Autistic Society (UK) – autism and mental health resources

• BEAT Eating Disorders (UK) – acknowledges autism and ARFID overlaps

• Mind (UK) – neurodiversity and eating disorder information

• Neurodiversity Podcast / lived experience blogs – first-person insights from AuDHD adults

• King’s College London research on autism & anorexia

These references reflect both research and lived experience. Neither alone tells the full story, together, they help us understand why eating disorders in AuDHD people are about survival, not failure.
