What Is ARFID? A Guide for Care and Support Teams

ARFID stands for avoidant/restrictive food intake disorder. It's an eating disorder where someone avoids certain foods, limits how much they eat, or both, and it isn't driven by worries about weight or body shape. It affects children, teenagers and adults. What sets it apart from fussy eating is the harm it does to the person's health or daily life.

What ARFID is

The NHS describes ARFID as avoiding certain foods, limiting how much is eaten, or both. Reasons can include strong feelings about a food's smell, taste or texture, an upsetting past experience with food, or simply not feeling hungry or interested in eating.

ARFID was introduced as a diagnosis in the American Psychiatric Association's DSM-5 in 2013, and it also appears in ICD-11, the WHO's international classification of diseases. Before that, some services used terms such as feeding disorder or selective eating disorder. ICD-11 describes the avoidance or restriction as causing harm to nutrition or significant problems in daily life, and not explained by a lack of available food, another health condition, or concerns about weight or shape.

The three common presentations

The eating disorder charity Beat describes three main reasons for the avoidance or restriction:

• Sensory-based avoidance: strong sensitivity to the taste, texture, smell, look or temperature of food. Someone may only manage a small set of foods that feel safe.
• Fear of what might happen: anxiety about eating, often after a distressing experience such as choking or being sick.
• Low interest in eating: a poor appetite or not noticing hunger, so eating feels like a chore.

More than one reason can apply to the same person, and sometimes there is no clear cause.

How ARFID differs from anorexia

In anorexia, restriction is linked to beliefs about weight and shape. In ARFID it isn't. Someone with ARFID may be underweight and want to eat more, but find they can't. Beat notes that ARFID can't be diagnosed at the same time as anorexia or bulimia, although one can come before or after the other.

The difference matters for support. Reassurance about body image won't help someone whose barrier is the texture of food or a fear of choking, and it can leave them feeling misunderstood.

How ARFID differs from picky eating

Lots of children go through a fussy phase, and plenty of adults have foods they won't touch. ARFID is different because of its impact. An East of England NHS review of ARFID research (2025) describes the effects to look for:

• weight loss, or a child not growing as expected
• nutritional deficiencies, such as anaemia
• relying on nutritional supplements or tube feeding
• a significant effect on family life and social opportunities

The same review notes that in young children ARFID can be very hard to tell apart from ordinary picky eating. That's why a proper assessment matters.

Who ARFID affects

ARFID can affect people of any age and any weight. It often starts younger than other eating disorders, sometimes from the age of two or three, and can continue into adulthood.

Beat says ARFID commonly occurs alongside anxiety disorders, autism, ADHD and some medical conditions. For autistic people, sensory differences around food are often part of the picture, so it helps if staff understand both. See our autism awareness training.

ARFID in adults

Some adults with ARFID have lived with it for years and may have been told they were just fussy. They may have built routines around a few safe foods and avoid meals out, work events or eating in front of others. In a care or support setting, that can look like someone refusing the menu or skipping communal mealtimes. It's worth asking why before assuming it's a preference.

Signs to look out for

Beat lists possible signs, including:

• eating a reasonable range of foods but far too little overall
• feeling full after a few mouthfuls
• always having the same meals
• avoiding social events that involve food
• weight loss, or in children, not gaining weight as expected
• nutritional deficiencies

Other things staff may notice include very slow eating, a sudden refusal of foods someone used to eat, or a clear fear of choking or vomiting. Record what you see and pass it on, following your local policy and the person's care plan.

Treatment routes in the UK

The first step is usually the GP, who can check physical health and refer on. For children and young people that is often to CAMHS. For adults, it depends on what local services offer.

NICE's eating disorders guideline, NG69, covers anorexia, bulimia and binge eating disorder, not ARFID specifically. Beat notes that ARFID isn't covered by the NICE or SIGN eating disorder guidelines, so what's available varies across the UK.

Treatment is tailored to the person and usually happens as an outpatient. According to Beat, it can include:

• cognitive behavioural therapy (CBT)
• family-based treatment for children and young people
• gradual exposure work and anxiety management
• dietitian support and physical health monitoring
• help with sensory difficulties
• medication in some cases, mostly for anxiety

The evidence base is still developing, so expect the plan to be shaped around the individual.

Supporting someone at mealtimes

For staff, the most useful thing is usually to take the pressure off. Follow the plan agreed with the person and their clinical team, and do it the same way on every shift.

• Keep safe foods available as the plan sets out. Running out of the one breakfast someone can manage can derail the whole day.
• Don't push, bargain or disguise food. Hiding a new food in a safe one can damage trust in the foods they do eat.
• Keep comments neutral. Avoid remarks about how much or how little someone has eaten at the table. Record intake afterwards if the plan asks for it.
• Think about the environment. Strong smells, noise, being watched or food touching on the plate can all make eating harder.
• Leave new foods to the plan. Exposure work is planned with the clinical team. Your job is to support it, not to add to it.
• Watch and report. Weight change, tiredness, dizziness, a drop in fluids or someone seeming unwell need passing on promptly to the nurse or GP.

Our nutrition and hydration training covers the wider basics of supporting people to eat and drink well.

How Kasorb can help

Kasorb's eating disorders training helps staff support people safely and compassionately, from supervising meals and snacks to understanding medical risk and working with families. The one-day meal support course covers the types of eating disorder, including ARFID, how eating disorders affect the body, supporting meals and snacks before, during and after, and the language and responses that help and those that don't. A four-day intermediate programme goes into more depth for teams working with eating disorders every day.

Both run on-site or live online for up to 12 staff, at one price for the group. Your trainer has used these skills for real and handles the subject with care. Certificates are emailed the next day, or the day after the final day for the four-day programme.

FAQs

What does ARFID stand for?

ARFID stands for avoidant/restrictive food intake disorder. It's an eating disorder where someone avoids certain foods, limits how much they eat, or both. Unlike anorexia, it isn't driven by concerns about weight or body shape. It can affect children, teenagers and adults, at any weight.

Can adults have ARFID?

Yes. ARFID often starts in childhood but can continue into adulthood, and adults can be diagnosed with it too. Some adults have lived with it for years and may have been told they were just fussy. They may rely on a small set of safe foods and avoid social situations that involve eating.

Is ARFID the same as picky eating?

No. Picky eating is common and usually doesn't harm health. ARFID is diagnosed when the avoidance or restriction causes real problems, such as weight loss or poor growth, nutritional deficiencies, reliance on supplements or tube feeding, or a big impact on daily and social life. A GP or specialist service can assess it.

Is ARFID linked to autism?

The eating disorder charity Beat says ARFID commonly occurs alongside autism, as well as anxiety disorders, ADHD and some medical conditions. Sensory sensitivity to taste, texture or smell is one of the main reasons for food avoidance in ARFID, which is one reason the two often overlap.

How is ARFID treated in the UK?

Treatment is tailored to the person and usually outpatient. It can include cognitive behavioural therapy, family-based treatment for young people, exposure work, anxiety management, dietitian support and physical health monitoring. ARFID isn't covered by the NICE eating disorders guideline, so services vary across the UK. The GP is usually the first step.
