Key Takeaway
Recognize that sensory processing and interoceptive differences uniquely shape eating disorder experiences in autistic adults.
This systematic review synthesized qualitative evidence from 13 studies to explore the lived experiences of autistic adults with eating disorders. The review highlights that eating disorder experiences cannot be understood independently of autistic ways of processing the world. Specifically, sensory sensitivities, interoceptive differences, and a preference for predictability were found to fundamentally shape the development, maintenance, and recovery of these conditions.
A key finding is that sensory-driven food restriction is frequently experienced independently of body image concerns, suggesting a potential conceptual overlap with Avoidant/Restrictive Food Intake Disorder (ARFID). The authors argue that recovery is facilitated when support aligns with autistic needs rather than neurotypical assumptions, emphasizing the importance of integrating autism into personal identity.
Clinical implications suggest that assessment, formulation, and intervention should adopt autism-informed, individualized approaches. These approaches must specifically recognize and address sensory processing and interoceptive differences. Because the evidence is qualitative, it does not provide quantitative effect sizes or establish causal links, but it highlights the necessity of specialized, nuanced care for this population.
How this fits prior evidence
This systematic review extends the finding that autism and eating disorders are linked, particularly for conditions not involving low body weight, which require specialized support and early identification. It specifically addresses the gap regarding how sensory-driven food restriction may occur independently of body image concerns, potentially overlapping with ARFID. The findings support the need for specialized support mentioned in previous scoping reviews of autism and eating disorder presentations.
For many autistic adults, the experience of an eating disorder is tied deeply to how their brains process the world. A review of lived experiences shows that these individuals often face sensory sensitivities and a need for predictability that shape how they interact with food. These factors can lead to food restrictions that are driven by sensory issues rather than body image concerns.
Because of these unique experiences, standard recovery paths might not always fit. The research suggests that recovery happens best when support is tailored to autistic needs. This means moving away from standard assumptions and instead focusing on the individual's specific sensory processing and internal feelings.
Clinicians are encouraged to use autism-informed approaches. By recognizing the overlap between autism and conditions like Avoidant/Restrictive Food Intake Disorder (ARFID), providers can offer more personalized care. The goal is to help patients integrate their autism into their identity while finding a path to health.
What this means for you:
Recovery for autistic adults with eating disorders requires support that respects their specific sensory needs.
Common questions
How does autism affect the experience of an eating disorder?
For autistic adults, eating disorders are often tied to how they process the world. Sensory sensitivities, a need for predictability, and differences in how they feel internal body signals can shape how they eat. These factors can lead to food restrictions based on sensory issues rather than body image.
What makes recovery different for autistic adults?
Recovery is more successful when support aligns with autistic needs instead of standard assumptions. It involves helping the individual develop self-understanding and integrating their autism into their personal identity. Treatment should be individualized to address their specific sensory processing and internal experiences.
Is there a link between autism and specific eating disorders?
The research notes that many autistic adults experience food restrictions driven by sensory issues. This often overlaps with Avoidant/Restrictive Food Intake Disorder (ARFID). Because of this, clinicians are encouraged to use autism-informed approaches to provide better care.
IntroductionAutism and eating disorders frequently co-occur, yet relatively little is known about how autistic adults experience eating disorders. MethodsThis systematic review synthesised qualitative evidence to explore the lived experiences of autistic adults with an eating disorder and inform autism-informed clinical practice. A systematic search identified 13 eligible studies, which were appraised using the Critical Appraisal Skills Programme (CASP) Qualitative Checklist and synthesised using thematic synthesis.ResultsFindings were organised into three themes: eating disorder experiences cannot be understood independently of autistic ways of processing the world; recovery is enabled through developing self-understanding and integrating autism into personal identity; and recovery is facilitated when support aligns with autistic needs rather than neurotypical assumptions. Autistic characteristics, particularly sensory sensitivities, interoceptive differences, and a preference for predictability, fundamentally shaped the development, maintenance, and recovery of eating disorders. Sensory-driven food restriction was frequently experienced independently of body image concerns, highlighting potential conceptual overlap with Avoidant/Restrictive Food Intake Disorder (ARFID).DiscussionAutistic adults described eating disorders as inseparable from their autistic experience, indicating the need for a paradigm shift from conceptualising autism and eating disorders as co-occurring conditions towards a model rooted in lived phenomenological experience. Clinical assessment, formulation, and intervention should adopt autism-informed, individualised approaches that recognise sensory processing and interoceptive differences, while future research should examine these mechanisms across a broader range of eating disorder diagnoses.Systematic review registrationhttps://www.crd.york.ac.uk/PROSPERO/, identifier CRD420261375735.
