ARFID: What It Is, Why It Happens, and How a Dietitian Can Help

Avoidant/Restrictive Food Intake Disorder (ARFID) is a pattern of eating where someone eats very little, avoids certain foods, or has a limited range of “safe” foods — not because of body image concerns, but because eating feels difficult, overwhelming, or unsafe in some way. ARFID can affect people of any age, background, or body size, and it often goes unnoticed or misunderstood.

1

What ARFID Is

ARFID is a recognised eating disorder characterised by one or more of the following:

  • Strong sensory sensitivities to taste, texture, smell, or appearance
  • Fear-based avoidance, often linked to choking, vomiting, or illness
  • Low interest in food or eating, including difficulty recognising hunger cues
  • Restricted intake that leads to nutritional deficiencies, weight changes, or impacts on daily life

People with ARFID may rely on a very small number of familiar foods, avoid entire food groups, or feel unable to try new foods without distress. It can affect energy levels, growth (in children), social situations, and overall wellbeing.

Why ARFID Happens

ARFID doesn’t have a single cause. Instead, it often develops from a combination of factors:

Sensory processing differences

Many people with ARFID experience heightened sensory responses. Certain textures, smells, or temperatures can feel unbearable or unsafe.

Neurodiversity

ARFID is more common in autistic individuals, people with ADHD, and those with other neurodevelopmental differences. Executive function challenges, sensory needs, and routine-based eating patterns can all play a role.

Past negative experiences with food

Choking, vomiting, food poisoning, or medical procedures can create long-lasting fear around eating.

Low appetite or reduced interoception

Some people simply don't feel hunger strongly or find eating effortful.

Anxiety

Anxiety can amplify sensory discomfort, reduce appetite, or make new foods feel threatening.

ARFID is never a choice. It’s a response to genuine internal experiences that make eating difficult.

How a Dietitian Can Help

Working with ARFID requires a gentle, collaborative, and highly individualised approach. My role is to support you (or your child) in a way that feels safe, respectful, and achievable.

Together, we might explore:

Your current safe foods

Understanding what works well now — and why — is the foundation for any progress.

Sensory profiles and patterns

Identifying textures, temperatures, flavours, and environments that feel comfortable.

Nutritional adequacy

Ensuring you're getting enough energy, protein, vitamins, and minerals, even within a limited diet.

Gentle food expansion

Introducing new foods slowly and safely, using sensory-based steps that respect your comfort and autonomy.

Reducing overwhelm

Strategies for meal planning, predictable routines, and reducing the cognitive load around eating.

Managing fear-based avoidance

Supporting you to rebuild confidence around eating after difficult experiences.

Working alongside other professionals

If needed, I collaborate with psychologists, speech and language therapists, or other specialists to ensure joined-up care.

My aim is never to push or pressure. Instead, we work at your pace, focusing on what feels meaningful and possible for you. Progress with ARFID is often gradual — and that’s completely okay. Every step counts.

When to Seek Support

You might benefit from dietetic support if:

  • Eating feels stressful, overwhelming, or exhausting
  • Your diet is very limited and affecting your health or energy
  • You're avoiding foods because of fear or sensory discomfort
  • Mealtimes are causing anxiety or impacting daily life
  • You're supporting a child whose eating is becoming increasingly restricted

You don’t need a formal diagnosis to get help. If eating feels difficult, that’s reason enough.
