Understanding the Overlap Between Eating Disorders and Neurodivergence
If you've spent years feeling like your relationship with food is complicated in a way that's hard to explain, you're not alone. The connection between neurodivergence and eating disorders is real, and it's finally getting the attention it deserves
Eating difficulties can sometimes be linked to more than just food. For many neurodivergent
people, including those with ADHD or autism, things like sensory sensitivities, emotional
regulation challenges, routine, and overwhelm can all influence eating behaviours.
At times, these patterns may overlap with eating disorders or disordered eating, which can
make the whole experience feel confusing, frustrating, or like no one quite gets it.
So what does the overlap between neurodivergence and eating disorders actually look like, and why does it matter when it comes to treatment?
Are neurodivergent people more likely to have an eating disorder?
Research and clinical experience increasingly show a strong overlap between eating disorders and neurodivergence, particularly autism and ADHD.
This does not mean all neurodivergent people develop eating disorders, or that all eating difficulties are caused by neurodivergence. However, for some people, neurodivergent traits can significantly shape their relationship with food and eating.
Understanding this overlap can help support feel more validating, individualised, and effective.
What is the link between autism and eating disorders?
The overlap between eating disorders and neurodivergence can show up differently for different people. Some common examples include:
Sensory sensitivities
Certain textures, temperatures, smells, or tastes may feel genuinely overwhelming or intolerable. This can lead to a limited range of "safe" foods or real difficulty trying new foods.
Need for routine and predictability
Changes to meals, environments, or food availability can feel highly stressful. Eating patterns may become rigid or repetitive as a way to create a sense of predictability and reduce anxiety.
Emotional regulation difficulties
For some people, eating behaviours can become linked to coping with overwhelm, stress, boredom, or intense emotions.
Executive functioning difficulties
Planning meals, remembering to eat, grocery shopping, or initiating cooking can feel genuinely difficult or exhausting, particularly for people with ADHD.
Social masking and burnout
Some neurodivergent people spend a lot of energy trying to "keep up" socially or mask their difficulties. Over time, this can contribute to exhaustion, shutdown, emotional distress, and changes in eating patterns.
Is ARFID the same as picky eating?
From the outside, certain eating behaviours can look very similar while being driven by completely different underlying experiences.
For example, avoiding foods may sometimes be linked to body image concerns, but for someone else, it could be connected to sensory sensitivities or a fear of change. Similarly, rigid eating routines may be about anxiety reduction, predictability, or emotional regulation rather than anything to do with weight or appearance.
ARFID (Avoidant/Restrictive Food Intake Disorder) is a good example of this. It involves extreme food restriction driven by sensory aversions, a fear of choking or vomiting, or low food interest. It's common in autistic individuals and is a clinical eating disorder that warrants proper support, not just encouragement to "try a bite."
How does ADHD affect eating habits?
For many people with ADHD and disordered eating, the connection isn't always obvious at first.
Executive dysfunction can make multi-step tasks like planning meals, writing a grocery list, and
initiating cooking feel genuinely exhausting. Time blindness means meals get skipped without even noticing. And impulsivity or dopamine-seeking can drive binge eating behaviours that have nothing to do with hunger.
These patterns are neurological, not a lack of willpower.
Why are eating disorders in neurodivergent people often missed or misunderstood?
This is exactly why understanding the "why" behind behaviours is such an important part of treatment. From the outside, the behaviours can look identical to a neurotypical eating disorder.
Food restriction may look like anorexia, but the underlying driver is completely different.
Sensory overload versus fear of weight gain. Routine versus control.
When treatment doesn't account for this, it can feel invalidating and ineffective, which is why so many neurodivergent people feel like they've fallen through the gaps of traditional care.
How can therapy treat an eating disorder in someone with autism or ADHD?
Therapy can help by exploring both the eating behaviours themselves and the factors that are
contributing to them. This may include:
Understanding sensory, emotional, or executive functioning challenges
Building flexibility around eating in a gradual and manageable way
Reducing shame around food and eating difficulties
Developing alternative coping strategies for overwhelm and distress
Supporting emotional regulation and self-understanding
At Psychwest, support is tailored to the individual and considers the broader context of someone's experiences, not just the eating behaviours alone. Where appropriate, therapy may include evidence-based approaches such as CBT-E, alongside neuro-affirming and emotion regulation-focused strategies.

If eating feels stressful, overwhelming, rigid, or emotionally loaded, it may be worth reaching out for support. You don't need a formal diagnosis, and you don't need to wait until things feel "serious enough" before asking for help.
Understanding the underlying drivers behind eating behaviours can often reduce shame and help people feel more supported and understood. Recovery isn't about forcing perfection. It's about building a safer, more sustainable relationship with food, eating, and yourself.
