Why OCD and Eating Disorders Often Happen Together
Eating disorders and obsessive-compulsive disorder, or OCD, can look different on the outside, but they often share a similar internal experience: intrusive thoughts, anxiety, rules, rituals, and a desperate need to feel “safe” or “in control.”
Research suggests that people with eating disorders are significantly more likely to also experience OCD compared with the general population. This does not mean eating disorders are “just OCD,” but it does mean the overlap is important to understand, especially when recovery feels stuck or hard.
At recoverED Clinic, we support clients who describe feeling trapped in loops such as:
“I know this rule does not make sense, but I still feel like I have to follow it.”
“If I do not check, count, plan, weigh, compare, or repeat it, something feels wrong.”
“My brain knows I am trying to recover, but my body feels panicked when I break the rule.”
How OCD and eating disorders can overlap
OCD involves intrusive thoughts, images, urges, or doubts that create distress. Compulsions are behaviours or mental rituals used to reduce that distress. Eating disorders can also involve distress-driven rituals, especially around food, body checking, exercise, reassurance seeking, calorie counting, weighing, comparison, or “perfect” eating.
For some people, eating disorder behaviours become a way to manage obsessive fears, such as:
fear of weight gain
fear of losing control
fear of contamination or food being “unsafe”
fear of eating the “wrong” thing
fear of body changes
fear of uncertainty
fear of not doing recovery “perfectly”
This can create a painful cycle: the ritual reduces anxiety briefly, but over time, the brain learns that the ritual is necessary. The eating disorder becomes louder, more rigid, and harder to challenge.
The role of perfectionism and control
Many people with OCD and eating disorders describe a strong need for certainty, order, or correctness. This may show up as rigid food rules, body checking, repetitive reassurance seeking, or feeling unable to move on until something feels “just right.”
This is not vanity. It is not attention-seeking. It is not a lack of willpower.
Often, it is the nervous system trying to create safety through control. The problem is that eating disorder rules and OCD rituals do not create real safety; they usually make life smaller.
Why recovery can feel so uncomfortable
Recovery often asks people to do the exact thing their OCD and/or eating disorder tells them is dangerous: eat the feared food, reduce checking, tolerate uncertainty, rest, change routines, or stop seeking reassurance.
That is why recovery can feel wrong before it feels right.
In therapy, we may work on gently interrupting the loop between fear and ritual. This might include CBT-E for eating disorders, exposure-based strategies, response prevention, body image work, values-based action, and trauma-informed support. For clients who are neurodivergent, treatment may also need to be adapted to consider sensory needs, interoception, demand avoidance, masking, and burnout.

When to seek support
It may be time to seek help if food, body image, exercise, checking, or reassurance seeking is taking up a lot of mental space, affecting your health, disrupting relationships, or making your world feel smaller.
Support is available, and you do not need to wait until things feel “bad enough.”
At recoverED Clinic, we provide compassionate, evidence-informed therapy for eating disorders, OCD traits, anxiety, trauma, body image concerns, and neurodivergence. We work with adults across Melbourne and Australia via telehealth, with a focus on care that is trauma-informed, neuroaffirming, and respectful of the whole person.
