Episode 435: Eating Disorder vs OCD—How to Tell Them Apart and Why It Matters
Host: Kimberley Quinlan, LMFT | Guest: Dr. Giulia Suro, PhD
Release Date: May 26, 2025

Overview

This episode explores the often-confusing overlap between Obsessive-Compulsive Disorder (OCD) and eating disorders, diving into how to differentiate the two, why proper diagnosis matters, and the implications for treatment and recovery. Host Kimberley Quinlan and psychologist Dr. Giulia Suro discuss practical tips for clinicians, address common misconceptions, and offer hope for those struggling with co-occurring conditions.

Key Discussion Points and Insights

1. Why Distinguishing OCD from Eating Disorders is Essential

• Accurate diagnosis is critical for appropriate treatment, as the motivations and therapeutic approaches can differ significantly.
• Many behaviors (tracking food, ritualistic eating) can look the same externally but stem from different internal drivers (01:26).
• Quote:
  “There’s lots of ways that food can get tangled up in obsessive thinking and compulsions... if we’re engaging in compulsion with food because we have fear of losing control of our bodies or a fear of gaining weight loss, the treatment could look really different than if we have fear of eating meat... because we believe it will offend God or our parents will get sick...”
  —Dr. Giulia Suro [01:26]

2. Key Diagnostic Differences: Ego-Syntonic vs. Ego-Dystonic

• Eating disorders: Behaviors and thoughts usually feel “ego-syntonic”—they align with an individual’s values and beliefs (e.g., “I must be thin to be worthy”), which makes them harder to challenge.
  • “Having a fixation on food or preoccupation with food or weight loss is pretty much normalized in our society.” —Dr. Suro [05:08]
• OCD: Thoughts are “ego-dystonic”—they feel intrusive, unwanted, and inconsistent with one’s self-image, leading to distress.
  • “With OCD, the thoughts are often intrusive. They're ego dystonic, meaning we don't want to be there. They're not consistent with our values.” —Dr. Suro [04:25]

3. Food-Related OCD vs. Eating Disorders: Presentation and Examples

• OCD: May manifest as compulsive rituals around contamination (e.g., fear of germs in food), symmetry (food arrangement), or needing the “right” thought while eating (07:00–08:18).
• Eating disorders: Preoccupations are usually around weight, body image, caloric intake, and have broader societal support, making them subtler to detect.
• Memorable moment: Kimberley shares that she once disguised her eating disorder compulsions as normal behaviors due to societal beliefs (04:38).

4. Overlap and Co-Occurrence

• 40% of people with eating disorders may also experience OCD; around 20% with OCD may also have an eating disorder (02:45).
• Co-occurrence makes clinical assessment and integrated treatment essential.

5. Approaches to Treatment: Similarities and Differences

• OCD: Exposure and Response Prevention (ERP) remains the gold standard.
• Eating Disorders: Exposures are vital but might not be labeled as such; focus is on developing an intuitive, non-restrictive relationship with food and body (09:50–11:35).
• Quote:
  “Recovering from an eating disorder in our society requires this massive leap of faith because we're asking you to challenge so much messaging...”
  —Dr. Suro [10:28]

The 'Whack-a-Mole' Phenomenon

• Reducing symptoms in one domain (e.g., OCD) may lead to an increase in another (e.g., eating disorder behaviors); coordinated, team-based care is crucial (15:43–16:15).

Importance of ACT (Acceptance and Commitment Therapy)

• ACT focuses on underlying thought processes and value-based actions, helpful for both disorders, especially when distress resurges after behaviors decrease (16:15–17:46).
• Quote:
  “ACT really focuses on those underlying processes... Rather than trying to challenge our thoughts, we are using mindfulness and acceptance to notice the thoughts for what they are, intrusions.”
  —Dr. Suro [17:26]

6. Managing Co-Existing OCD and Eating Disorders

• Integrated treatment with exposure work that alternates between food and non-food exposures can address both conditions (17:57).
• It's essential not to avoid food exposures, even when working on non-food OCD themes.
• Exposures must be gradual, collaborative, and at the patient’s pace—never jumping straight to the hardest tasks (19:47–20:42).

7. Core Fears in Eating Disorders vs. OCD

• For eating disorders, exposures may genuinely result in the feared outcome (e.g., weight gain), so therapy involves exploring and tolerating deeply-rooted fears, societal fatphobia, and self-compassion (21:52–24:14).
• Recovery involves challenging, accepting, and finding value-driven motivation, not just waiting for anxiety to go away.
• Quote:
  “The exposure started the day that I wanted to get better more than I wanted to stay in this situation.”
  —Kimberley Quinlan [24:58]

8. Clinical Challenges & Assessment Tips

• Difficulties in thorough assessment and time constraints impeding holistic care [26:01–28:43].
• Importance of team-based care (dietitian, therapist, psychiatrist) and regular use of OCD and trauma assessments (Y-BOCS, Life Events Checklist) (35:21).
• Delicate balance between integrating vs. separating treatment approaches for overlapping symptoms.
• Quote:
  “There’s just not enough time in 50 minutes to address and have the person be feeling seen and heard for all that they're suffering with.”
  —Kimberley Quinlan [27:23]

9. Myths and Misconceptions

• Society and even clinicians often misidentify eating disorders as problems only for “underweight” people; in reality, most people with eating disorders are not underweight (31:28–32:18).
• Not all compulsions are visible—many are mental (34:10).
• OCD is still confused with OCPD (“I’m just a perfectionist”), minimizing the distress involved.
• Many people are hesitant to share their real intrusive thoughts, impeding proper diagnosis (34:26–35:21).

Notable Quotes and Memorable Moments

• “Having a fixation on food or preoccupation with food or weight loss is pretty much normalized in our society. ... It's tough to parse out when all of our—the messages that we're receiving from our society is telling us this is the right thing to do.”
  —Dr. Giulia Suro [05:08]

• “I really believe recovering from an eating disorder in our society requires this massive leap of faith.”
  —Dr. Giulia Suro [10:28]

• “The exposure started the day that I wanted to get better more than I wanted to stay in this situation.”
  —Kimberley Quinlan [24:58]

• “There's just not enough time in 50 minutes to address and have the person be feeling seen and heard for all that they're suffering with in a 50 minute slot.”
  —Kimberley Quinlan [27:23]

• “Yes, full recovery is possible, and you should not settle until you achieve full recovery. You deserve it and it’s attainable, so don’t cut yourself short.”
  —Dr. Giulia Suro [37:27]

Conclusion and Message of Hope

Both hosts emphasize that FULL recovery from both OCD and eating disorders is possible and should be the goal—not settling for a life still dominated by obsessive thoughts or rituals. Intensive, empathic, and value-driven treatment—with enough teamwork, time, and self-compassion—can help individuals build a meaningful life beyond these diagnoses.
