What is the Connection Between Eating Disorders and Neurodiversity?

Over the past few years there has been increasing awareness of the link between eating disorders and neurodiversity. Many people who struggle with eating difficulties are also discovering that they may be neurodivergent, and for some this realisation can suddenly make a lot of things make sense.

I often find that when clients begin to understand how their brain works, it can bring a sense of relief. Instead of feeling like something is wrong with them, they start to see that some of their experiences with food, routines, emotions or sensory sensitivities may be connected to the way their mind processes the world.

Research is still developing in this area, but studies consistently show that neurodivergent people, particularly those with autism or ADHD, appear to have a higher likelihood of developing eating disorders. Understanding this connection can help us approach eating difficulties in a more compassionate and individual way.

What is neurodiversity?

The term neurodiversity describes the natural differences in how human brains work. Some people process information, emotions, sensory experiences and routines differently from what is considered neurotypical.

The concept was first introduced in the 1990s as part of a movement within the autism community. Rather than viewing neurological differences purely as deficits, the idea was to recognise them as part of the natural diversity of human thinking.

Today, neurodiversity is often used as an umbrella term that includes conditions such as autism, ADHD and other learning differences.

This perspective does not mean people don’t need support. Many neurodivergent individuals benefit from understanding, adjustments and specialist help. However, it encourages us to recognise that these differences are not simply problems to be fixed, but ways of experiencing the world that come with both strengths and challenges.

Autism and eating disorders

Research suggests that a significant number of people with eating disorders also show autistic traits. Some studies estimate that around one in five people with eating disorders may be autistic.

Autism is often associated with differences in thinking patterns, sensory processing and routines. These traits can sometimes intersect with eating behaviours in ways that increase vulnerability to eating difficulties.

For example, autistic individuals may feel more comfortable with structure and predictable routines. Food can sometimes become organised around strict rules or patterns which gradually lead to restrictive eating.

Sensory sensitivities can also play a role. Certain textures, smells or flavours may feel overwhelming, which can make some foods difficult to tolerate. Because of this, some autistic individuals may have a very limited range of foods they feel comfortable eating.

In some cases this may develop into conditions such as ARFID (Avoidant Restrictive Food Intake Disorder), where eating becomes restricted due to sensory sensitivities, fear of certain foods or a lack of interest in eating. In these situations the difficulty is often less about body image and more about comfort, predictability or sensory experience.

ADHD and eating disorders

ADHD is another neurodevelopmental condition that appears to have strong links with eating disorders.

ADHD is typically associated with difficulties with attention, impulsivity and emotional regulation. These traits can influence eating behaviours in several ways.

For some people, impulsivity can make it harder to regulate eating habits, which may contribute to patterns such as binge eating. Emotional regulation can also play a role, as food may sometimes be used as a way of managing overwhelming feelings.

People with ADHD may also struggle with routines and planning, which can make maintaining regular eating patterns more difficult.

Sensory experiences and food

For many neurodivergent individuals, food is not simply about hunger or enjoyment. Sensory experiences can have a significant impact.

Texture, smell, temperature and even the appearance of food can affect whether someone feels comfortable eating it. Some people may only eat specific foods or brands because they know exactly what to expect.

This is often misunderstood as picky eating, when in reality it reflects genuine sensory sensitivity.

Understanding this can be an important step in supporting someone who is struggling with eating difficulties.

How I work

When I work with clients who are experiencing eating difficulties, I take an integrative approach. This means we look at the whole picture rather than focusing only on food.

Together we might explore things such as emotional regulation, stress, sensory sensitivities, routines and the beliefs someone has developed about themselves and their body. If neurodiversity may be part of the picture, we also consider how someone’s brain processes the world and how that may influence their relationship with food.

My aim is always to create a safe and non-judgemental space where clients can begin to understand themselves more clearly. Rather than trying to force change, we work at a pace that feels manageable and supportive.

For many people, developing a kinder understanding of themselves is a really important part of recovery.

A more compassionate understanding

Eating disorders are complex and rarely have a single cause. However, recognising the role that neurodiversity can play helps us move away from a one-size-fits-all approach.

When we begin to understand how someone’s brain processes the world, it becomes much easier to see why certain eating patterns may develop.

With the right support and understanding, people can begin to build a healthier and more balanced relationship with food, one that works with their mind rather than against it.
