Avoidant restrictive Food Intake Disorder Subtypes

ARFID (Avoidant Restrictive Food Intake Disorder) is an eating disorder characterized by the persistent avoidance or restriction of food intake.

This disorder can lead to stunted growth, no weight gain in children, significant weight loss, nutritional deficiencies, and social isolation. There are several subtypes of ARFID, including:

  1. Avoidant subtype: This subtype is characterized by a heightened sensitivity to certain sensory aspects of food, such as taste, texture, smell, or appearance.

    Individuals with this subtype may refuse to eat certain foods due to their sensory properties, even if they are otherwise healthy and nutritious. This subtype is typically thought of as "picky eating." ARFID is not the same thing as picky eating.

  2. Aversive subtype: This subtype is characterized by a fear of negative consequences associated with eating, such as choking, vomiting, or allergic reactions.

    Individuals with this subtype may avoid certain foods or food groups due to fear of these consequences, even if they have never experienced them. This subtype can also happen after a traumatic experience suffered by the individual or witnessed by them.

  3. Restrictive subtype: This subtype is characterized by a general lack of interest in food and eating.

    Individuals with this subtype may have little appetite or desire to eat and may only eat when hungry or feel obligated to do so. These individuals are often distracted and need to remember to eat. These individuals tend to be underweight and malnourished.

  4. Mixed subtypes: This subtype mixes two or more of the above subtypes. It typically starts with one subtype and then, over time, develops into two.

    My loved one started with an aversive subtype (fear of vomiting) that later developed into a restrictive subtype.

  5. ARFID Plus subtype: This subtype is characterized by having one of the above subtypes, plus anorexia nervosa or binge eating disorder (BED).

    Individuals with ARFID plus start with having one of the ARFID subtypes, then over time, develop anorexia nervosa or BED.

    One of the main differences between ARFID and anorexia/BED is that individuals with ARFID are not concerned with their body weight, shape, or size. Once they are concerned with their body size, anorexia and BED arise.

It is important to pay attention to how you or your children eat. I'm a registered dietitian and didn't pick up on my child's ARFID for five years. I thought I was teaching my kid how to eat intuitively.

He ate most of everything I gave him and stopped when he was "full." I put full in quotes because his anxiety was telling him he was full. He was actually under eating. I sought help when he hadn't gained appropriate weight, complained of constant stomach pain, and had feelings he couldn't explain (anxiety).

His ARFID started as a fear of vomiting and anxiety and now includes a disinterest in eating.

A comprehensive evaluation by a qualified healthcare professional is necessary to accurately diagnose and treat ARFID. If you have any inkling there might be an eating issue, seek help from an eating disorder specialist.

I Paid My Child to Eat

I paid my child with avoidant restrictive food intake disorder, or ARFID to eat.

Why? He challenged me. He asked if he ate all of his lunch plus a grande Starbucks Frappuccino, would I pay him. Yes, I would.

While many professionals wouldn't agree with my approach, I believe this was a great opportunity for exposure work that he brought up himself. This was huge for him on so many levels, but here are the top three.

1. He has aversive and restrictive ARFID. He has fear and anxiety about vomiting and believes if he eats too much he will throw up. For many years, he continually restricted his intake. His anxiety kept telling him to eat less and less to avoid vomiting. So, for him to eat everything on his plate and a Frappuccino is a huge success. He pushed past his comfort level and dealt head-on with his anxiety.

2. We were at a restaurant. Eating at restaurants is another anxiety of his. This is a common anxiety for most people with ARFID. This can be due to a variety of reasons, such as not being able to find safe or familiar foods, feeling uncomfortable in an unfamiliar setting, or worrying about being judged by others for their restricted eating habits. These anxieties can lead to avoidance of restaurants altogether, which can limit social opportunities and lead to feelings of isolation.

3. I wanted him to prove to himself that he can do it. Anytime you push past anxiety, you are providing evidence that the anxious thought is not true. He will now be able to pull up this memory (evidence) when his anxiety is high. Remember, avoidance increases anxiety. The reverse is also true. Confronting fear decreases anxiety.

He did try to make this deal again at dinner and I told him no. I don't plan to make this a reoccurring event. Continually paying a child to eat is not an effective or sustainable approach to managing their ARFID in the long term. However, I will add it to my toolbox if we ever need to use it.

So, how did it go? He ate everything. He was proud of himself for pushing past his discomfort and achieving something that a year ago he thought was impossible. He was also happy he made $15.

Overall, a big success.

Weight Gain with Avoidant Restrictive Food Intake Disorder

The first goal you want to tackle with avoidant restrictive food intake disorder, or ARFID is weight restoration and nutrient deficiencies. This is the absolute first place to start even if you or your loved one only eats a limited variety of foods.

This was the first goal we started when my child was diagnosed. He was around 15 pounds underweight and had several vitamin and mineral deficiencies. And because he has an aversive/restrictive subtype, I knew eating a lot of food was out of the question.

So I focused on high-calorie, low-volume foods. This turned into a huge trial and error. For him, it came down to eating real ice cream (not a dairy dessert) and a milkshake daily.  For you, it might be something else. It's important to try different foods and not get hung up on what society or people tell you is "healthy."

High Calorie, Low Volume Foods

The following foods are great for people that have food fear, low appetite, and low interest in eating. Keep in mind, this list is not exhaustive.

Dairy:

  • Milkshakes

  • Smoothies

  • Muffins

  • Ice cream (not dairy dessert)

  • Full fat cheese

  • Full fat yogurt

  • Whole milk

  • Cream

  • Butter

Baked Goods:

  • Muffins (made with whole milk and nuts)

  • Banana bread (add walnuts)

  • Cookies, (ex. peanut butter, monster cookies)

  • Energy balls

 Meat:

  • Full fat meats (ex, chuck beef)

  • Sausage

  • Bacon

  • 80/20 ground beef

  • Chicken thighs

 Snacks:

  • Peanut butter snack bars

  • Perfect bars

  • Nuts (ex. macadamia nuts, almonds, pecans)

  • Seeds (ex. Sunflower, flax, chia, hemp)

  • Chips

  • Nut butters

  • Seed butters

  • Granola

  • Regular soda

Fruit:

  • Avocado

  • Coconut

  • Dried fruit

 Supplements:

  • Ensure

  • Benecalorie

  • Carnation breakfast essentials


It's important to note that while these foods may be high in calories, they may not necessarily be the best choice for everyone. Like I said before, there is a great deal of trial and error to see what works for you or your loved one. For the longest time, I was held up on my loved one eating more nutrient dense foods that were also calorically dense. For us, that was the wrong way to go. It came down to him needing to gain weight no matter what.

Because he was also deficient in several vitamins and minerals, I had to turn to supplements. There was no way we could focus on weight gain while also eating foods high in vitamins and minerals. Foods that are high in vitamins and minerals, such as fruit and vegetables, are low in calories. In a future post, I will go into more detail about what weight restoration looks like, but until then keep adding more high-calorie foods even if it’s a few bites. Don’t give up.

Why Having an Eating Routine is Important with ARFID

Most individuals with ARFID, especially those newly diagnosed, greatly benefit from following an eating routine. A routine sets the tone for what is to come and what is expected. It helps those with anxiety feel more grounded, and it helps those with absolute disinterest and distraction to eat.

Why an eating routine is important with ARFID

Benefits of a routine

The benefits of following an eating routine are:

  • Less anxiety

  • Regulate hunger and fullness cues

  • Establish grounding and coping skills

  • Regulate GI functions

  • Less stomach pain from anxiety

So, what does an eating routine look like?

An eating routine will look different for each individual, but for most, it should include:

  • Set meal and snack times

  • Specific time spent at the table

  • Specific environment setting, e.g. noise, lighting, scents, people

  • Coping tools, if needed

  • Specific days for eating out, e.g. every Thursday

  • Specific restaurants

People with ARFID tend to be sensory sensitive and need a more strict routine. Sensory sensitivity can include sensitivity to specific foods or utensil textures, sensory noises (my kid hates the noise paper napkins make when using them), super tasters, and lighting.

Trying new restaurants can cause anxiety. This anxiety typically causes stomach pain in many people with ARFID, especially if their diet is limited. Going to a new restaurant might need to be treated the same as exposure work.  

Here is an example of my family and ARFID kiddo's eating routine.

  • All meals are at the kitchen table. 

  • Breakfast is at 6:30 a.m. My kiddos eat together and pick the food they want to eat. I oversee in the kitchen.

  • Lunch is at 10:30 a.m. and eaten at school. My kiddos pick the food they eat. 

  • Snack is at 3:00 p.m. My ARFID kiddo and I eat together. 

  • Dinner is at 6:00 p.m. and the entire family eats together. This meal includes safe foods and exposure food. Due to my kid's ARFID subtype, most exposure foods are based on volume and not specific foods.  

It might take some trial and error to figure out what works. It might also change during and after recovery, always adapting. The point of the routine is that it serves the person with ARFID and their family. An eating routine is important to the treatment and recovery of ARFID.
