ARFID and Anorexia Nervosa

SIMILARITIES

DIFFERENCES

Restrictive eating

Body and shape concern
AN - “feeling fat” ARFID - preoccupied with the number – i.e. not wanting the weight to change/ to go up (fixation/rigidity but not because they “feel fat”)

Anxiety at meal times

Anxiety at meal times
ARFID – not knowing what to expect
AN – fear of calories/volume of meals

Weight loss

Difficulties at a very young age
ARFID usually before 10
AN usually teenagers

Rigidity – OCD??

Sensory issues
ARFID most of the times is present
AN can be present but usually not (unless those on the spectrum)

Meal times as most difficult moment of the day

Type of food eaten
AN will avoid carbs, fats and will have fear foods
ARFID no pattern but usually they will eat biscuits, chocolate or a food that for AN is
considered fear food

Impact on family and social situations / isolation

Obsession around food
ARFID + ASD – numbers, specific things, rigidity
AN – obsession about calories (fear of gaining weight) + rituals/rigidity mostly due to
starvation

ARFID and Autism

• Strong visual processing – visual cues and why packages are so important

• Home cooking is difficult to manage as won't be similar all the time

• Every detail is important

• They usually don’t look to the food (because after taking a bite, you change It visually and therefore it looks different)

• Usually they will eat different foods in different environments (i.e. just eat nuggets at school and not at home – conditional cues
become part of the food)

• Use of distractions around meals – for MDT and family discussion

• Meal times and activities ideally should be at the same time every day –
CONSISTENCY ('If I know what it will happen, I get less
anxious')

• Use a visual timetable to explain what happens at mealtimes and during the day (i.e. school timetable) – to avoid anxiety

• Use a visual meal plan

• Importance about looking for early communication

• Food is visually inconsistent

• Sensory preparation before meals
