Research consistently finds high rates of co-occurrence between OCD and eating disorders. Up to 40% of people with eating disorders meet criteria for OCD at some point in their lives. The reverse is also common.
This is not coincidence. They share a deep mechanism.
The shared architecture
Both conditions involve:
1. An obsessional thought (about contamination, harm, body shape, food, weight)
2. An anxiety surge in response to the obsession
3. A compulsive behaviour that neutralises the anxiety (washing, checking, restricting, purging, exercising)
4. Short-term relief that reinforces the loop
5. Long-term entrenchment as the loop tightens
The thoughts differ. The mechanism is identical.

Why this matters for treatment
Treating only the eating disorder while leaving the underlying OCD architecture untouched is a frequent reason for relapse. The behaviour changes; the mechanism remains; new compulsions develop.
Treating only the OCD without addressing the eating disorder behaviours leaves significant medical risk in place.
Integrated recovery
The most durable outcomes come from integrated work:
1. Specialist eating-disorder care for the medical and behavioural management
2. OCD-focused work (or, in the LAR model, sensitised anxiety-response work) for the underlying mechanism
LAR Coaching's approach addresses the upstream anxiety response that powers both the OCD and the eating-disorder loops simultaneously. For many clients, this is the missing piece — the work that allows the eating disorder to genuinely resolve, not just shift to a new compulsion.
