The Male Eating Disorder Matrix

What is the Male Eating Disorder Matrix?

The Male Eating Disorder Matrix is a clinical framework introduced by Dr Philippe Jacquet in his University of Essex doctoral research, The Devouring Kronos (2026). It identifies four positions that recur in clinical work with men who have eating disorders. The Matrix is not a typology of patients: it maps what happens between two people, what arises in the man, and what arises in the clinician.

It was developed specifically for men, in a field where the treatment models in general use were derived largely from female populations.

The four positions:

1. Shame
2. Identification and the Blueprint
3. The Father Figure
4. The Power Struggle

Why the Matrix exists

In Dr Jacquet’s words:

Over the years of working with eating disorders, I came to see that working with men was not the same as working with women. In the room with a male patient, different parts of my own personality were activated. I could feel unconscious dynamics taking place that were not as obvious, or as systematic, with women. My doctoral research began there, as an attempt to understand those dynamics. At first I guessed they had to do with the father and son relationship. Over the course of the research I became convinced of it.

So the whole doctorate was an attempt to understand what was actually happening in the clinical room, and to build tools a professional could use to recognise it while it was happening. The need was practical. Where the clinician does not understand what is going on unconsciously, the therapy can end early, and no one quite knows why.

But the greater loss is quieter. An important part of the dynamic between patient and analyst goes unseen, and with it an important unconscious process of the patient himself. What is not recognised in the room cannot be worked with. The man leaves, or stays and stalls, and the material that mattered most was never brought into the light.

Why the positions are not labels

The four positions describe what arises between two people. That is the point of them.

The more a clinician understands what is taking place, the more they can contain it, and the more the patient feels contained. Containment is not a stance one adopts. It is the by-product of understanding. The Matrix is an instrument for strengthening it, by making visible the dynamics that would otherwise work in the dark.

How the Matrix was built: the consulting room as laboratory

The Matrix was developed using the single-case methodology set out by R.D. Hinshelwood in Research on the Couch: Single-case Studies, Subjectivity and Psychoanalytic Knowledge (Routledge, 2013). Hinshelwood’s argument is that clinical material is research data in its own right, and that the single case, properly handled, can test a psychoanalytic theory rather than merely illustrate it.

On that model the consulting room becomes a laboratory, and the analytic relationship is placed under the microscope. The procedure is to establish a benchmark: what the theory predicts should appear. Then two things are observed in parallel. First, the behaviour of the patient: what he brings, enacts and repeats. Second, what the therapist feels, with the countertransference recorded as data rather than set aside as noise. It is the interaction of the two, the patient’s material and the analyst’s response occurring together as predicted, that validates the operationalisation of a concept.

The four positions

1. Shame

The silent conviction that one’s suffering and one’s body are fundamentally wrong. For a man the shame is doubled: the shame of the illness, and the shame of having what the culture calls a woman’s illness. This is why he trains instead of talking, why the disorder disguises itself as discipline, and why he may spend years presenting the problem as anything but what it is.

2. Identification and the Blueprint

A boy becomes what he has seen. The father is the image through which a son learns what it is to be a man, the blueprint of masculinity, and the son needs a father whose body he can identify with: a real body, imperfect, inhabited, at ease enough with itself. Where that identification is unavailable, the culture’s bodies rush in to fill the vacancy: the hero, the strongman, the young god.

3. The Father Figure

When the archetypal need for the father goes unmet, the man seeks identity where identity can be manufactured: in his body, or in addiction. This is the territory of the Kronos Complex and the pursuit of Body Number 2. The disorder here is not about food. It is an attempt to father oneself.

4. The Power Struggle

The disorder becomes the one place the man can exercise power. Life may be uncontrollable, the past unreachable, the future frightening, but the body obeys: what enters it, how it trains, what it weighs. Restriction, purging and compulsive exercise are experienced not as illness but as sovereignty, the last territory he rules. This is why confrontation fails. To attack the disorder is to attack the only power he has left.

Each position has a corresponding movement in the clinician. Those indicators, and how they direct the clinical work, are set out in the doctoral thesis and developed in a book in preparation.

How the Matrix differs from other frameworks

It is not a diagnostic instrument. Screening and severity measures assess the disorder in the patient. The Matrix concerns what is happening between the patient and the clinician. The two answer different questions.

It is not a typology of patients. A man is not a Shame patient or a Power Struggle patient. He occupies a position, which is a property of the encounter and can change within a session.

It is not a stage model. Frameworks such as the stages of change describe a sequence a patient moves through. The Matrix has no sequence and no endpoint.

It is not general countertransference theory. The use of the analyst’s experience as data is long established. What the Matrix adds is specificity: which dynamics recur in this population, and what each asks the clinician to attend to first.

Who it is for

It was written for clinicians working with men, including those whose training was built on female presentations. Men themselves, and the people close to them, often recognise the positions too, though the Matrix is not a self-assessment tool and cannot be used as one.
