Autism and Eating Disorders 101: Where is the Overlap and How do we Support Neurodiverse Recovery

Written by: Tiluka Bhanderi, BSc RD

At Fresh Approach Nutrition, many of the patients we work with have a diagnosis of autism alongside an eating disorder. In this blog, we’ll look at the link between autism and eating disorders and explain how dietetic support can be adapted to meet neurodiverse needs during recovery.

Why autism and eating disorders often coexist

Research shows higher rates of eating disorders especially anorexia and ARFID among autistic individuals. This doesn’t mean autism causes an eating disorder instead it reflects the overlapping traits such as sensory sensitivities, ridgid routines, attention to detail and anxiety around change. These shared traits can significantly shape how someone relates to food and their body.

How autism can shape someone’s relationship with food

For many autistic people, food and eating are shaped strongly by sensory experiences. Textures, smells, temperatures or tastes that seem neutral to others can feel overwhelming or even unbearable1. Over time, this can result in a smaller range of “safe foods” not due to choice or control but because familiarity and predictability help reduce distress.

Routines around eating can also feel deeply regulating. Having the same meals at the same times may provide a sense of safety, but it can make flexibility around food changes feel challenging2. Social eating, unfamiliar environments and noise can increase anxiety and reduce appetite. Differences in interoception such as difficulty recognising hunger or fullness cues can further disrupt eating patterns3. When these factors overlap, they contribute to patterns seen in autism and eating disorders, which are often misunderstood as purely psychological rather than rooted in neurodiverse experiences.

Why traditional eating disorder support doesn’t always fit

Not all conventional therapy approaches account for the nuances of autism and eating disorders such as sensory needs, communication preferences or structure and this can leave autistic individuals feeling unseen or misunderstood.

Autistic people may feel misunderstood or pressured to mask their behaviours rather than supported to understand and adapt them. This can make recovery feel harder and makes neurodiversity-informed care all the more important.

How dietitians support autistic clients with eating disorders

At Fresh Approach Nutrition, our registered dietitians tailor support to honour each client’s unique experience. Sessions are structured and predictable, with clear communication so clients know what to expect and feel safe. We adapt nutrition strategies around sensory preferences and executive function needs and use tools like visual aids, and gradual exposure to help you make consistent progress without rigidity. We also work closely with therapists, occupational therapists and GPs where needed to ensure your treatment is well rounded.

Building a supportive environment for recovery

Recovery is not a one-size-fits-all process, families, partners or carers can make a significant difference by understanding sensory needs, routines, and the pace at which change feels comfortable. Progress may look different from traditional expectations, but it is equally meaningful and worth celebrating.

Support should feel collaborative, not corrective. When care respects an individuals neurodiversity, it becomes easier for eating to feel calmer, safer, and more sustainable.

If you’re autistic and finding food stressful or overwhelming, know that support exists that respects your needs. Our dietitians work collaboratively to make eating feel calmer, safer, and more sustainable. Book a discovery call today to find out how we can support you.
