Many individuals with autism spectrum disorder (ASD) can experience eating challenges that feel confusing or overwhelming, and learning more about this connection can help create space for better understanding and support.
Eating Disorders Awareness Week
The National Association of Anorexia Nervosa and Associated Disorders (ANAD) and the National Eating Disorders Association (NEDA) are prominent non-profits that focus on the prevention, alleviation, education, treatment and advocacy of eating disorders.
Observed the last week of February, Eating Disorders Awareness Week (EDAW) and National Eating Disorders Awareness Week (NEDAW) strive to promote the awareness of eating disorders as a serious mental health condition. The effort has evolved into an annual campaign, where individuals can spread their own stories across social media, attend webinars or hear about recent advocacy efforts.
Since the early 2020s, the aforementioned nonprofit organizations have placed an increased emphasis on diversity when it comes to eating disorders, recognizing that many marginalized communities face unique challenges and barriers to treatment. NEDA’s theme for their 2026 NEDAW campaign is Every BODY Belongs, explaining “eating disorders affect 30 million Americans across all ages, sizes, races, genders and backgrounds. Too often, people go unseen or unsupported due to stigma, misinformation and barriers to care.”
In line with these ongoing conversations, Maxim Behavioral is highlighting one marginalized group that may receive less public attention when it comes to eating disorder awareness. In this article, we explore the relationship between individuals with ASD and eating disorders, including patterns that can appear within this population and factors that may shape these experiences.
Feeding and eating problems
Many individuals with ASD experience feeding differences, including but not limited to:
- Strong preferences for specific textures
- Avoidance of certain textures, tastes or temperatures
- Limited food variety
- Rigid mealtime routines or rituals
- Preference for foods with consistent brands, colors or packaging
- Eating foods in a particular order
- Avoiding foods that touch one another on the plate
- Sensitivity to smells
- Difficulty trying new foods
While these behaviors are not necessarily indicative of eating disorders on their own, research suggests they can be more persistent and intense in youth with an ASD diagnosis compared to their neurotypical peers. Some individuals with intense feeding differences may have avoidant restrictive food intake disorder (ARFID), a condition where sensory differences or anxiety around eating can significantly limit the types or amounts of foods that feel comfortable. One study reported an estimated 43% of individuals with ARFID also had ASD.
These experiences can feel overwhelming, making it understandable to wonder what is typical or what may need more attention and making it harder to tell everyday feeding differences from signs of a deeper concern.
Adding to this complexity is the natural overlap between ASD traits, such as narrow or restrictive preferences, sensory sensitivities, or a need for predictability, and the symptoms seen in eating disorders. Because terminology varies across studies and medical records, some experiences that could point to an eating disorder may instead be attributed to ASD. When this happens, individuals with ASD may not receive support that could bring them comfort, simply because their symptoms are assumed to be part of their neurodevelopmental profile rather than a cooccurring condition or possible eating disorder. This can understandably be frustrating for families seeking clarity and compassionate guidance.
Connections to body image
Even with growing interest in the connection between ASD and restrictive eating patterns, there remains a significant gap in research focused on eating disorders shaped by body image concerns in individuals with ASD.
Thoughts about bdy dissatisfaction or focuses on weight or shape are part of conditions like anorexia nervosa and bulimia nervosa, and while some opinion articles online discuss personal experiences or possible connections between ASD, body image and diagnosed eating disorders, few studies have examined this in depth.
Restrictive eating disorders are also more commonly observed in women and girls, and ASD is often under diagnosed in women and girls, which can make this relationship even harder to understand. Some girls with ASD may hyperfocus on body image or appearance to fit in socially, and this can be part of how they mask their differences in environments where they feel pressure to blend in.
Without clearer insight into how body image disturbances may develop in individuals with ASD, it becomes harder to distinguish sensory-based feeding challenges from eating disorders rooted in body perception. It also limits opportunities to tailor supportive approaches that reflect both a person’s neurodiversity and their emotional wellbeing. Continued research in this area offers hope for more compassionate, individualized care, striving so that no one’s experiences are overlooked simply because they do not fit traditional presentations.
Maxim Behavioral
If you’re a parent and have concerns about your child’s eating behaviors, you should first discuss with your child’s clinicians who can help you explore what may be contributing to these experiences.
Eating behaviors can be an important goal to work on through applied behavior analysis (ABA) therapy, where your family and one of our Board Certified Behavior Analysts (BCBAs) collaborate on supportive strategies that feel realistic, meaningful and tailored to your child’s goals and needs. For more information on our ABA services, reach out to your local office to learn more.
