A
If you've ever found yourself questioning, is it OCD or is this an eating disorder? You are not alone. The struggle of untangling eating disorders versus OCD can feel confusing and overwhelming, especially when your thoughts and behaviors overlap. In today's episode, I am joined by Julia Surow to bring clarity, exploring the differences and surprising similarities and what all that means for you. Whether you're trying to understand your own experience or you're looking for practical steps towards recovery, this conversation is designed to help you find answers and hope. So let's dive in and make sense of what you're going through. Welcome, Julia.
B
Thank you so much for having me. I'm really excited to be here.
A
Yes. I'm so thrilled, actually. It's so wonderful that you had reached out to me because this is actually a question we get a lot and one that I'd like to cover a little more here in the future. So I. Today. Well, actually, Theo is here, too, as he always is for the podcast. These days, we're really wanting to understand the differences between eating disorders versus ocd. Why is that so important for the diagnosis and treatment of people?
B
Well, I think getting at sort of the underpinning, particularly the obsessions and what's driving them, can be really helpful in informing an effective treatment plan. So there's lots of ways that food can get tangled up in obsessive thinking and compulsions and rigidity and rules and all the things we're going to talk about. But if we're engaging in compulsion with food, whether it's counting or tracking or restricting certain food groups 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 that we haven't seen prepared because we believe it will offend God or our parents will get sick or something like that. So we really want to be that curious observer and understand what is sort of driving some of the obsessive thoughts and the compulsions that are coming into play to regulate the distress around them.
A
Amazing. So for somebody who's presenting with some of these behaviors, how might we differentiate the difference between whether it's specifically ocd? What would that look like compared to an eating disorder? And then I will actually, after you explain it, I'll actually share a personal experience that I had as well.
B
Oh, cool. Okay. I might speak out of, like, every side of my mouth in this. In this part, because I think diagnostic criteria can be helpful and if it's serving to get us to the treatment that we need. And also I think these diagnostic criteria can be incredibly unhelpful. We know there's a lot of overlap and as much as 40% of people who have an eating disorder also have co occurring OCD. For OCD, it's like 20% have an eating disorder. So there's a lot at play. And most people who have an eating disorder have another co occurring diagnosis, whether it's OCD or PTSD or an anxiety disorder. So there's a lot going on. I actually really like to take what's called a trans diagnostic approach and not focus so much on like, oh, that's an obsessive thought that belongs in the OCD pile, that's a compulsive behavior that belongs in the eating disorder pile. And really just like look at your brain, the way your mind is working, what's helpful when what's unhelpful, what behaviors are working for you, what's not, what do we want to change? This is very much informed by acceptance and commitment therapy, which I've spoken to you about before. However, I think one thing that really distinguishes eating disorders from OCD in terms of the cognitions is the thoughts that come up in the context of an eating disorder tend to be egosyntonic, meaning they are consistent with our currently held views or values, good or bad. So in our society, restricting our diet to lose weight or trying to change our body is something that is socially acceptable. And so having thoughts that I am good if I do that matches or it can.
C
Right.
B
With ocd, the thoughts are often intrusive. They're ego dystonic, meaning we don't want to be there. We don't want them to be there. They're not consistent with our values and our sense of self. They can be scary and frightening.
A
Absolutely, absolutely. And I will share. You know, as someone who suffered with an eating disorder, it was very in line with my values. Like I believed it to be true that in those days that it would be bad if I gained weight and that, you know, I would do anything. I would do a lot of what seems like just regular daily compulsions, but they would. I was doing them because I was terrified of my body changing.
B
Yeah, absolutely. I think that's an really important point. Having a fixation on food or preoccupation with food or weight loss is pretty much normalized in our society. And also tracking food, engaging in ritualistic food behaviors, they might not be described that way, is also like sort of normalized. So it's tough to parse out.
D
Right.
B
When all of our. The messages that we're receiving from our society is telling us this is the right thing to do. Look better, feel better. We could spend a lot of time talking about orthorexia as well as obsessive compulsive personality disorder, which tends to be more ego syntonic. It's. The thoughts aren't as frightening or intrusive. It's more around rigidity and perfectionism, which can get totally played out with clean eating, healthy eating, pure eating, things like that.
C
Right.
A
So interestingly for the listeners is I totally put Julia on the spot today because we were going to talk about food related obsessions and then I totally was like, we're changing it. Can we change it?
B
So thank you for being so flexible. It's important. There's a lot to talk about. Yeah.
A
But just briefly, like a food related obsession you'd mentioned, like contamination. Like what are some of the behaviors people do when they have OCD around food?
B
OCD around food specifically. I think the. Some of the behaviors can look like a lot of tracking, counting, keeping meticulous logs, a caloric count that you can't go over that's sort of like arbitrary. I remember having a client years ago that it was like, this week it's 1300, next week it's 1600, without any sort of rhyme or reason. But there's this profound sense that if I go over that something bad will happen. So we'll get tied up with morality.
D
Right.
B
Or that sort of scrupulosity. Eating this food makes me a bad person. And so all of a sudden we have sort of these good foods and bad foods and we start to architect our life around them. Disgust. I also years ago had a client who had a lot of contamination obsessions. And so working with raw meat, eating meat that wasn't prepared in a very specific way or cooked in a very specific way became really problematic and distressing. And that started to generalize to other types of food.
A
Absolutely, absolutely. And to add to that, I've had examples of clients where it was just around symmetry.
D
Right.
A
Like that food needed to be symmetrical or it needed. Or it didn't. Couldn't touch each other for contamination reasons. Or they had to have the right thought when they swallowed a food. So they would be pushing the food around and parents would immediately take them to an eating disorder specialist thinking that they were. That's what was going on. But this person is having this whole inner turmoil of having the right thought and so forth.
B
Yes, yes. That just.
D
Right, right.
B
So thank you for bringing that up the way the food is presented, what it's touching on the plate, the number of times we have to cut it up or chew.
D
Right.
B
Like the number of bites we take, these can all be enormously distressing behaviors that get tied up with the food.
C
Yeah, yeah.
A
And I think that going back to the first thing, I think that's why it's so important that we do pass apart. What is what? Because the treatments are different.
D
Right.
A
Let's use that as a segue. So how does therapy for OCD differ from therapy with an eating disorder?
B
Well, the good news is there's a lot of commonalities. Right. So exposure is going to be a part of it. We know that exposure response prevention remains the frontline treatment for ocd. And, and I think that whether it's an official version or not is really important. When we're working towards eating disorder recovery, we cannot get around eating. And the path towards eating disorder recovery is having a more intuitive, trusting relationship with food, which means eating again and again and again and practicing sort of letting go the fears, the control, the rigidity that takes place with an eating disorder. I think because there's so many parts at play and there might be other co occurring diagnoses, it can also be really important to take a more holistic approach in addition to the exposure work. So doing family based work, potentially trauma focused work, a lot of relapse prevention, again, I'm a big proponent of act. Cognitive behavioral therapy also remains a gold standard.
C
Yeah.
A
For me, the first part of eating disorder treatment was slowing down, particularly because it was a belief. I think I had sort of being sort of trained as societally to believe that I needed to be thin and that it was better to be thin and all these other very distorted beliefs. The first part was actually just being able to identify like that that wasn't true, that that wasn't a fact is.
B
Probably the best thing.
A
Like that society had maybe pushed that onto me and there were newer other ways of thinking which kind of blew my mind.
B
I think that's brilliant.
D
Right.
B
And that can be tough to get to. It might sound sort of sense, it makes sense to the people listening, but for someone with an eating disorder, that is a huge leap. I really believe recovering from an eating disorder in our society requires this massive leap of faith. Because we're asking you to challenge so much messaging that we're just spoon fed from every angle around what our body should look like, our worth based on our bodies, what a regular eater looks like, what a lunch should look like, a dinner Et cetera, et cetera, when we eat dessert, when we don't, how we express our emotions in relation to food, all that stuff.
C
Yeah.
B
So that's not a small thing.
C
Yeah, for sure.
A
And just to sort of back you too is. There was a huge component of exposure therapy in my treatment, but it was never called that. Never once did we call it erp. It was more. We would call them experiments or it would be more. Are you willing to like, are you willing to try this? Are you willing to try that? And that was pretty terrifying, especially because you still held those beliefs even though you were beginning to challenge them.
B
Yeah, absolutely. That's why I think for anyone out there who's struggling with an eating disorder or thinks they might be and is in therapy or working with a dietitian, asking about doing food exposures in session or again that's, that's a very technical term. But just eating with someone else in a controlled, safe setting, it can be a really, really good opportunity to practice some of the fear foods that might be on your list. Or using things, spreading some peanut butter without a measuring spoon. Right. Like whatever those challenges are around control or rigidity, having sort of a safe place to do that.
A
For sure. For sure. So we've talked a little about the differences between the presentation of food related OCD compared to an eating disorder. And of course there are different types of eating disorders too, which we, we won't have enough time to go into completely. But what are the signs that someone might be dealing with both or how would somebody identify that they are dealing with both?
B
Both.
A
What would that look like?
B
Sure. So what we know is that of the different eating disorder diagnoses that exist, which are problematic, but it's what we have. OCD tends to be most common with the diagnoses that have a restriction component that could be anorexia nervosa, restricting type or binge purge type as well as arfid. And restriction can also be present with binge eating and bulimia of course. But we know it's when there's that sort of rigidity, control fixation, rule based thinking and behaviors around food that could be a red flag that there might be a co occurring presence of ocd.
A
Yeah, I think that's where it's really interesting too because some of my patients with OCD and an eating disorder, so when they have both have used. I'm just curious to hear your thoughts on this. Have used restriction as almost a form of punishing themselves. You know, is that something that you have seen in your practice or you know, as a form of like holding back any kind of pleasure or anything nice for themselves. Is that something you see?
B
Yeah, absolutely. So there's a assessment tool that's used to sort of measure the different underlying drivers of eating disorder behaviors called the Eating Disorder Inventory. And one of the scales is called asceticism. And it sort of has an interesting history I won't get into, but there was a cluster of nuns, I think, in the 17th century that starved themselves as a sign of devotion to God. And so it's this act of real self deprivation. At some points it can be real punishment that's guilt driven, you don't deserve to eat. But in other places it's just I'm better if I experience less pleasure. And we see that with food eating, but also across the board. So this might be the client that won't spend money to get their hair cut, that won't buy clothes for themselves when they need them, that their hygiene might be a bit poor. Sort of this punishment, self deprivation across the board.
A
Right, exactly. Let's say somebody does have both and how might they manage that effectively? And the reason I want to also say, and maybe you can speak to this is often in my practice, whether I'm the person working on the eating disorder or the OCD or both, sometimes I'm working in communication with another clinician. Let's say the other clinician is working on the eating disorder and I'm doing the ocd. We find this sort of whack a mole of one, the OCD goes down, but the eating disorder goes up. And then once we get the eating disorder down, maybe some other themes of OCD pop up. So how might somebody manage both of them effectively, knowing that that's not true for everybody, but can happen?
B
Yes. I have lots of thoughts about this. I think what the evidence shows is when there are really two true distinct sort of diagnoses of OCD that might be contamination or just. Right. Or whatever it is, plus an eating disorder. And they're really different and they play out in different ways. We want to do the exposure response prevention work, creating a hierarchy, but make sure that food is happening every other exposure and finding a way to tie them in. However, I'm going to make a plug for acceptance and commitment therapy here.
D
Right.
B
And this is why I really love this modality in the context of eating disorders, which can often feel like a game of whack a mole, whether it's OCD or substance use or self injurious behaviors.
D
Right.
B
We oftentimes when we sort of get the eating disorder under control, and by that I mean when the behaviors have remitted, right. Distress goes up because we've taken away a means of self regulation. And so we see other things then start to pop up. ACT really focuses on those underlying processes. So a really amazing ACT skill. ACT is made up of six components. They are called the ACT Hexaflex. One of them is called cognitive diffusion. And it's a skill that can be applied to any sort of type of thinking that is unhelpful. And rather than trying to challenge our thoughts, this is where it differs a bit from cognitive behavioral therapy. Even though it's definitely in the same family. Rather than trying to identify distortions and challenge them and replace our thoughts with more balanced thinking, we are using mindfulness and acceptance to notice the thoughts for what they are, intrusions. Or that's an eating disorder based thought. Or that's a diet culture thought.
D
Right.
B
And see them with some objectivity and some space and then use that space to direct our attention into the present and engage in behaviors that are more helpful. And there's lots of different diffusion exercises that are really easy to put into play. I'd be happy to share more or we can talk about that another time. Sure.
C
Yeah.
A
Can you go back to how you were saying the exposure practice with eating in between? Can you elaborate a little more on what that would look like?
B
Sure. So let's say someone has anorexia nervosa and contamination phobia. And also I'll caveat that they are medically stable and are in a place to be doing food exposures, which if you're in therapy for either an eating disorder or ocd, you wanna make sure you're medically stable before doing any sort of food exposure work. We might have someone, I actually remember doing this a long time ago, eat a meal in McDonald's, right. And we would practice doing it without washing our hands first and sort of sit with the uncertainty of what might come up around that. And we're also challenging a fear of food. And then the next exposure might be going into that McDonald's bathroom and like drinking water from out of the sink. Nothing related to, but we're sort of tackling more of the contamination. The next exposure, we might bring in food and do that in a different way. Eating in a different public setting or touching the ground and the dirt and then eating with our hands, something like that. So we, we don't want to lose sight of the food. We don't want to collude with any avoidance around the food piece. We want to keep integrating that thread through the exposure work to make sure the clients are gaining momentum and working their way through the hierarchy. Right.
A
But that is so hard for those people. Like, speaking because you're adding. It's like a double whammy. Like you're. You're hitting two major fears at the same time. Does that. You know, we often, we work either, you know, in a gradual exposure way or we, let's say we might take away gradual exposure and do more of an inhibitory learning approach. What would you say to someone who, you know, I'm hearing my clients in my, in my sessions just saying, like, oh, my gosh, the idea of doing both makes it go from like, easy to like a 10 out of 10. Do you have any?
B
Yes. Yeah, totally. Yes. And by the way, like, I would not ask someone to go to McDonald's on day one.
A
Okay.
B
Yes, it's true. And we do. I personally, and I think the evidence supports this. Like, I really believe in a gentle approach to exposures. You want it to feel like a win. You want to have that, like, high five at the end.
D
Right?
B
Yeah. And I have said to my clients in the past, like, we are co pilots here. Like, I'm going to be a bit more, I'm going to sound a bit more assertive. But you, you're. This is your work. We are in it together. However, this, the role of exposures is to build up that self efficacy.
D
Right.
B
Like, to show that you can do it, you've got this, you can do it. And so we want to push. And I think that's a challenge for therapists too.
D
Right.
B
To make sure we're not sort of holding back or colluding with a client's fears that this might be too much for them. So I always believe in sort of like understanding the comfort zone and let's find one inch outside of it.
A
Yeah, for sure.
C
Yeah.
A
And so the last piece here is, you know, when we're discussing the contrast between OCD and an eating disorder is often, and I'll be careful with my words here because I want this to, you know, we have to be clear in the words we use with ocd, Often people have an ego dystonic obsession and that they're pretty. They're not certain. But often their fears are like, they'll say, like, I know it's ridiculous. Like, I know it's crazy that whatever their obsession is. But with eating disorders, often the rebuttal they get when it comes to exposure is the exposure probably will cause them to gain weight over time. We want them to restore themselves back to a healthy weight that they can maintain and that nourishes them. How might you approach exposure for someone with a co occurring eating disorder who knows the exposure or is pretty sure the exposure will cause their biggest fear to come true?
B
Yeah, that's great. That's, that's, I think, really important to talk about. This is where, when sort of preparing to do exposure work I really believe in, I sort of call this like peeling the onion around core fears. Right. So if I eat dessert every day for a week, I'll gain weight. What would be so bad about that? What's the worst thing about that? Is it the loss of control? Is it feeling shame? Is it changes in your body that you don't think you can tolerate? Is it being in a body that was a place of trauma for you in the past?
D
Right.
B
Let's get a little bit deeper to what would be the worst possible thing about gaining weight. And now we want to walk you through the process of seeing this worst fear I believe you could tolerate might not be preferable. And I understand it's challenging. I, I always want to validate that with clients who need to gain weight as part of their eating disorder treatment. It is not hard, it's not easy to gain weight in our society.
D
Right.
B
Like that's not a process that's considered positive. It's hard to see our body change right when we don't want it to. And you deserve to take the time. You need to be gentle with yourself and self compassionate. That's why we don't want to flood you with really, really tough exposures. But we do want to show you that you can take it. And I think the process of weight restoration is a giant exposure for sure. However, I do want to say most people who seek treatment for an eating disorder exist in a body that is not underweight and they may even be in a larger body per CDC standards, which are problematic, but are what we have. So this, this applies to anyone who sees their body change as part of recovery. Yeah.
A
And that was a big piece of that first step for me, which was really understanding the role that fatphobia had in, in my life.
B
Sure.
A
That it was everywhere. Like I had to undo layer upon layer upon layer of fat phobia to even get to a place where I would consider exposure experiments with anything.
C
Yeah, yeah.
A
And that, that was a. But again, it was a fun. It was, it was a great. I was I loved those conversations. But it. It did challenge everything that I believe to be true in the world as it is.
B
Yeah, absolutely. And I think. I think this brings up why it can be helpful doing in doing any exposure work, not to rely on habituation, meaning I don't feel distress anymore.
C
Yeah.
B
This may just be super hard and really distressing and it might be the best thing for you and get you towards health and a full life and everything you want. And this may feel bad for a while and it may continue to be challenging.
C
Yeah.
B
There's no way around that. And can we observe those thoughts from a bit of a distance and see them for what they are? Can we feel the feelings? And then this is where act really brings in the values work, which I find is so helpful when we're talking about eating disorder recovery. Like, what is meaningful to you? What will get you through this really, really tough experience?
C
Yeah.
A
And that is so beautiful. That is a treatment that can be beautifully be used with both conditions. Because I know for myself it was the exposure started the day that I wanted to get better more than I wanted to stay in this situation. Like, I had to get clear on this isn't working. Like, I. I'd prefer to be in a different body than to sit and suffer in this messy circle that I'm stuck in.
B
Yeah, yeah, totally.
D
Yeah.
B
It's so true. I think that shift from in the treatment process, from sort of like fake it till you make it, to identifying like, okay, this is. There's something for me that I really want this for now is so is such an important shift to make and is what's really going to see the process through.
C
Yeah. Yeah.
A
So just for the clinicians, what challenges do clinicians usually face when diagnosing or differentiating between OCD and eating disorders?
B
I think there's a few. One, it's one. It's hard.
D
Right.
B
I think when there's an eating disorder at play, I'm curious your thoughts about this because I come from a primarily eating disorder background. I think when there's an eating disorder at play, there's sort of this fear of like, I need to get the eating disorder under control and sort of putting that first. And other diagnoses, whether it's OCD or ptsd, sort of get like lost in the shuffle, even though they're really the logs on the fire that are keeping the eating disorder alive. So I think doing like. Or take. Giving yourself the time to do a really thorough assessment of history, thoughts, behaviors, doing for clinicians, a Y box. I Think it's great to do with everybody with an eating disorder because the prevalence rates are so high. That's a OCD measure. Just sort of get a sense of, are there any other obsessions or compulsions? And then I think really looking at again, the functionality of the behaviors as they relate to the obsessions that they're trying to regulate or appease. What is the biggest fear about what might happen if you don't engage in this behavior or mental act? Is it, is it that you will gain weight or lose control of your body, or is it something that might be sort of outside of the domain of an eating disorder? And if it is, then that really opens up the world of different exposures that you can do and you can sort of give your clients a bit of. You can sort of, as we talked about, sort of thread in and out of food exposures and OCD exposures.
C
Yeah, yeah.
A
And I would, I would love everything you said. The only thing I would add is just the logistics of treatment. Like, the biggest challenge I've had is 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. Which has been why at our center we have either increased frequency of sessions, so maybe two sessions a week, or had another clinician come on the team and sort of separate the work. While we're both working together, we're creating a collaborative team to sort of. Because again, just based on the time, there's so much to get done in 50 minutes. So that would be another sort of thing that I think a challenge that we get. And it's hard because, you know, what is reasonable, that's very expensive, that takes a lot of people's time. They require people who have skills in both areas. And so if that's not possible, we may even just have them have a dietitian on the side where someone's doing their check in, someone's checking their vitals to make sure medically they're a good fit for outpatient instead of requiring more intensive treatment.
B
Yeah, I think that makes a lot of sense with eating disorders in particular. I think working as part of a team is so helpful so that ideally the therapist doesn't have to hold a ton of like the food police stuff.
D
Right.
B
Like, what did you eat this week? How many times did you purge?
D
Right.
B
Like, I really love it if I don't have to sort of monitor in that way. And I don't want to like put that all on the dietitian. But if we can sort of, like, share the responsibilities a bit, I think that can be really helpful. I remember at one point hearing an outpatient clinician talking about a case and saying, we're doing, like, one PTSD session and one eating disorder session or something like that. And I understand that, especially if you're using, like, a specific intervention for ptsd, but I think also to take the pressure off of yourself a bit, and we can focus on the thoughts and the behaviors.
D
Right.
B
Whether it's contamination or fear of weight gain.
D
Right.
B
Like, it's thoughts and behaviors, for sure.
A
I think that.
B
That.
A
I think that when you address it all at once, the big pro of that is it does reduce the whack. A mole, like, playing out of it, because you're. There's one focus and one way to deal with it, and it's pretty cohesive across. But it does get confusing when you're like, well, do I do this? Do I do that? What's the. What should I do for which.
B
So I love.
A
I think that's a really appropriate, you know, way to address it.
C
Yeah.
B
One point just.
A
Just on that.
B
When I. When I was training, this was 10, 15 years ago now for eating disorders, it really was this sort of, like, sequential model of get the eating disorder under control, and then you can tackle the trauma or OCD or anything else. But if you don't, like, get the eating disorder stabilized, anything else you address, well, then it will exacerbate the eating disorder.
D
Right.
B
And now what we know, particularly. I know I'm talking about trauma a lot, but what we know in the case of PTSD is, first of all, what would happen is, like, people would never get to their, like, ptsd. They would go home, and then they'd be triggered, and then they go back to their what. What they know has worked for them.
D
Right.
B
And I imagine the same is the case with ocd.
D
Right.
B
But if you do concurrent treatment, if you do them at the same time, they both get better. And I. And I think that's the case with. With ocd, where there's so much overlap and sort of the cognitive style and the types of behaviors and what's driving them. Rigidity, control.
D
Right.
B
If we can get them both at the same time, we can find sort of remission in both.
A
Yeah, absolutely. Absolutely. So before we finish up, I have one question that you could tie in this direction. But what myths or misconceptions exist around OCD and eating disorders that might hinder treatment? What might be getting in the way of people getting good care.
B
I think there's a ton. We could probably spend a whole episode on this, right? Certainly. I'll start with eating disorders. I think there's a ton of prevailing myths around what an eating disorder looks like. Most people in general society, including clinicians. Right. We don't get a ton of eating disorder training. I think many people are still stuck in sort of like the Lifetime movie, white cisgender, female college student, diet gone wrong.
D
Right.
B
And it's really about the food and weight loss. While that can be a big component, these are very complex illnesses and have deep roots. And often those roots are tied to another mental health struggle, whether it is obsessive thinking or high levels of anxiety, rigidity, perfectionism, trauma.
D
Right.
B
So really getting at the roots of the disorder, I think is still a struggle for many. For many individuals seeking treatment. Two, just based, as I said, on body size, like most people, in their sort of mind's eye, think of someone who's underweight when they imagine an eating disorder. And we know that's like less than 6% of people who struggle with these illnesses. And someone is much more likely to binge and be in a normal or larger body, again based on CDC standards, as opposed to someone who is underweight. So there's a lot of people who are struggling with an eating disorder. It's estimated to be about 10% of the baseline population, but only 27% of those who are struggling are going to get the treatment they need. So there's a lot there what an eating disorder looks like, and that it's not all about the food. I think that in terms of ocd, and I'm curious your thoughts about this as someone who specializes more in this area, that OCD and OCPD are conflated. So people think of OCD and they think it's like it's perfectionism, it's helpful, like you're a control freak. And like, these are very, very distressing experiences. They can be torturous. And so not sort of seeing how painful and distressing and destabilizing these cognitions can be, I still think is a real challenge or a barrier for people getting the care that they need. And over time, I've known people with OCD who've gotten, like, radically misdiagnosed, including bipolar. It's been confused as a delusion.
D
Right.
B
Or anxiety or autism spectrum disorder. I've, over the years known many people with anorexia nervosa, and their OCD has gone completely under the radar because it's again, it's sort of like it's believed to be all about the food. So I think we need to get better. It's really sort of assessing the obsessive thoughts and compulsions also, I think. Sorry to keep going, but the fact that not all compulsions are external behaviors.
D
Right.
B
There can be mental acts like that that still is a barrier for people being assessed. I think our general public, but also clinicians who aren't as well informed are still looking for like the checking of the locks or the hand washing.
A
And it's not that.
B
It's not always that way.
C
No.
A
And I think it's a language thing. Too often people with OCD never tell anybody about. They're too afraid to tell anyone about their intrusive religious obsessions or sexual obsessions or harm obsessions. Yes. And so they're not able to say the fear. And before they know it, they're being put in an eating disorder clinic with no one who's been treated for ocd. So many people we hear from in my practice have come from an eating disorder clinic. And then they're there for a few weeks and then the clinic is saying something. Something's not here. And I think that's the importance of that assessment. Because if the assessment, the Y box, the assessment for OCD is put in front of them, they're more likely to be like, oh, it's right here. Like I can say it because they've paper with it, which I think is helpful.
B
Yes. Yeah. I would say for any clinician listening, like a Y box, a trauma assessment. So like the life events checklist. And then also asking what is your relationship with your body and what is your relationship with food?
C
Yeah.
B
And give them an opening. Because similarly, people with eating disorders won't share. They think it's. They think it's normal. They think it's typical. Right. Like they're not doing things that are that different than the people they see around them.
A
Yeah. And that's true too, I think is people, a lot of my clients with anorexia don't actually know what a healthy sized meal looks like.
D
Right.
A
So for them eating maybe half of what I would eat now, to them, they actually have come to believe that that's too much, quote unquote, too much food. And so it's a lot of education around like the actual amount of food that you need to consume to keep your organs going and so forth. And that that's a full education that. That they weren't expecting to get.
B
Yes, totally. The other Thing we didn't talk about is interoceptive exposures. So really exposing yourself to the physical experience of different levels of fullness and noticing what comes up and hunger too.
D
Right.
B
Like, for one person, feeling hungry might be a sign of success. Right. Like that means I haven't eaten. I'm doing the right thing for, for someone else, it might feel out of control. It might mean if I eat, I'm going to binge, because I'm not.
A
I'm.
B
I'm too out of control right now. Fullness can bring up disgust. They are all sort of tied to different things, for sure.
C
Yeah.
A
Okay, so one last. I said the last question, but I'm just going to keep adding to the rest. We go. But the main thing I sort of want us to finish here in. If someone has, of course, eating disorder or an ocd, but even if they have a coexisting condition where they've got both, what is your experience? Can people recover from having these coexisting conditions? What are their outcomes looking like?
B
Yes, I want to say, 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. And what I mean by that, particularly in terms of an eating disorder, is sort of getting to a place where you can sustain a healthy weight or you can sort of get by, but you are still tortured by food. Obsessions, rules, rigidity, tracking.
D
Right.
B
No, not acceptable.
D
Right.
B
Keep going, keep if, Tell your therapist or find a new therapist.
D
Right.
B
Like bug them, nag them. It is. It is absolutely possible to have a place of ease in your mind, in your relationship with food and your body. And that doesn't mean that these thoughts, but they have much less power. They can be fleeting. You can see them for what they are. They're not distressing or bothersome.
C
For sure.
A
Yeah, I agree. I 100% agree. And I think that people need that hope because I think as soon as you do have that coexisting, you kind of feel like you're doomed. You know what I mean? Like, you know, how am I ever going to navigate getting out of this mess that I feel like I'm in? But it's. It is absolutely possible.
B
Yes. Yeah. Keep up the exposures. I mean, I really think doing ERP makes you a superhero, like, to be able to see. And I think it's important to celebrate and look back with pride.
D
Right.
B
Of what you've come through, to see the distress you've held, the challenges you've moved through that you wouldn't have imagined you could have done when you started.
D
Right.
B
And to keep it up and to go back to the model, if you find yourself sort of noticing an increase in symptoms, for sure.
C
Yeah.
A
Thank you so much. Can you tell us where people can hear about you, your practice, any social media that you have?
B
Yeah. So my name is Julia Sero. I have a website that's juliassuro.com and my name is spelled with a G, G, I, U, L, I, A. And you can also find me on Instagram @Juliasuro PhD.
A
Amazing. Amazing. And. And you can. I will also, in the show notes, have a link to previous episodes that you've been on here with us. And I'm really grateful. Again, my goal is speaking a little more about this because I think it's more prevalent than we think, as you've said. And so I'm so grateful for your time and knowledge here today.
B

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
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.
“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]
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.
