Patterns of compulsive, impairment-causing behavior that are the subject of active research but have not yet received formal diagnostic status in DSM-5-TR or ICD-11. Content throughout this section reflects research-derived frameworks, not codified diagnostic criteria.
How to Use This Section: The conditions covered here — exercise addiction, work addiction, and addictive-like eating behavior — are not formal diagnoses. None currently appear as discrete diagnostic entities in DSM-5-TR or ICD-11. Content throughout this section is educational and research-informed, drawing on peer-reviewed literature and research-derived frameworks. It is not intended for self-diagnosis and does not substitute for clinical evaluation by a qualified healthcare professional.
The conditions grouped here — exercise addiction, work addiction, and addictive-like eating behavior — share a common clinical profile: a pattern of compulsive behavioral involvement that the person finds difficult to regulate, that intrudes on daily functioning, and that persists despite awareness of its costs. In each case, the behavior itself is not inherently harmful; it is the loss of control and the resulting impairment that characterizes the clinical concern.
Researchers have proposed that these patterns fit within a broader behavioral addiction framework, mapping onto features such as salience, mood modification, tolerance, withdrawal-like symptoms, interpersonal conflict, and relapse after attempted reduction. This framework remains useful for clinical observation, though it does not yet carry the same evidentiary support as formally recognized conditions.
A critical practical point is that none of these behaviors are the target of clinical concern in their typical form. Regular exercise, productive work, and eating are all necessary parts of healthy life. The threshold is functional impairment and loss of volitional control — not the amount of time or intensity of engagement.
Across all three conditions, research identifies a similar profile: compulsive behavioral involvement, difficulty disengaging, preoccupying cognition outside the behavior, distress when the behavior is restricted, and real-world functional disruption — including effects on relationships, work, physical health, and sleep.
High training volume, professional dedication, and enjoyment of food are not clinical concerns. The threshold for each of these conditions is functional impairment and loss of volitional control — not the intensity or frequency of engagement. Social normalization of these behaviors makes impairment assessment essential; the absence of a formal code does not eliminate clinical relevance.
Because none of these conditions carry a formal diagnosis, there are no disorder-specific, randomized-trial-validated treatment protocols for any of them. Clinicians draw on extrapolated evidence from behavioral addiction and related fields. This limitation should be communicated clearly in clinical encounters.
The absence of formal diagnostic codes has practical consequences: affected individuals may go unrecognized, face barriers to reimbursement, and receive care addressing only downstream comorbidities. These patterns are associated with anxiety disorders, depression, cardiovascular risk markers, and significant relationship and occupational harm. Recognition is the prerequisite for appropriate formulation and support.
Understanding why these conditions sit apart from formally codified disorders helps clarify both their clinical significance and the limits of current evidence.
Neither the DSM-5 nor the ICD-11 recognizes exercise addiction, work addiction, or addictive-like eating behavior as discrete diagnostic entities. The DSM-5, which extended behavioral addiction recognition to Gambling Disorder, explicitly cited insufficient evidence as the basis for excluding other candidates. Both systems apply a deliberate evidentiary threshold, and the peer-reviewed literature for these conditions has not yet produced the convergent data on diagnostic criteria, clinical course, and validity that formal recognition requires.
The absence of a diagnostic code has real clinical consequences: affected individuals may go unrecognized, may face barriers to reimbursement, and may receive care that addresses only downstream comorbidities.
Across all three conditions, the research literature is still developing. Neurobiological mechanisms have not been directly established in any of them. For exercise and work addiction, no neuroimaging or genetic studies specific to those conditions have been published. For addictive-like eating, brain imaging research in humans offers meaningful analogical data, but much of the foundational work draws on animal models. Natural history — typical age of onset, course without intervention, predictors of remission — is largely unknown, owing to the absence of prospective longitudinal studies.
No randomized controlled trials have examined treatment efficacy specifically in these populations. Clinical guidance is derived by extrapolation from behavioral addiction and related disorder treatment literature.
Each of these conditions borders on one or more formally recognized diagnoses, which complicates differential assessment. Work addiction overlaps substantially with obsessive-compulsive personality disorder — historically, most recognized cases of compulsive overworking have been framed within that construct. Compulsive exercise, when occurring in the context of an eating disorder, is understood as a symptom of that disorder rather than a standalone condition. Addictive-like eating shares considerable overlap with binge eating disorder, a formally recognized diagnosis, with evidence that the two are related but not identical.
Differential diagnosis is an essential step in clinical formulation for each condition. Co-occurring conditions are common and influence treatment planning.
Because these behaviors are socially normalized — exercise is widely praised, overwork is professionally rewarded, and highly palatable food is ubiquitous — recognition depends entirely on careful, individualized clinical assessment of functional impact. Screening instruments are available for all three conditions, but none have been validated against a clinical criterion standard capable of anchoring a formal diagnosis. They yield risk stratification, not diagnosis. Distinguishing the condition from high engagement, passionate involvement, or culturally reinforced behavior patterns requires contextual clinical judgment rather than questionnaire scores alone.
Social normalization can render these conditions invisible to patients, family members, and clinicians, and may actively resist recognition of the pattern as a source of harm warranting clinical attention.
Each condition has its own dedicated hub with plain-language overviews, clinical reference material, and evidence summaries.
For some people, exercise can shift from something that supports health to something that controls it. The behavior no longer feels like a choice — it starts to feel like a compulsion. The key distinction is not how much a person exercises, but whether they have lost the flexibility to adjust when circumstances — injury, illness, or important obligations — demand it, and whether significant distress follows when exercise cannot occur.
Work addiction — sometimes called workaholism — describes a pattern in which a person feels a powerful, hard-to-resist drive to keep working, even when they want to stop, even when they are tired, and even when it is affecting the rest of their life. The key feature is a compulsive quality: the person feels internally pressured to work, and finds it difficult to mentally switch off even during evenings, weekends, or time with family.
For some people, the relationship with certain foods feels genuinely out of control — marked by intense cravings, repeated failed attempts to cut back, and distress about eating even when the consequences are clear. Research has found meaningful parallels between how the brain responds to highly processed foods and how it responds to addictive substances, while ongoing debate continues about how best to define and classify this pattern.
These conditions share overlapping patterns of impaired control, reinforcement, and functional impact. Exploring related areas may help clarify similarities and differences across behaviors.

A formally recognized behavioral addiction in which impaired control over gaming leads to significant disruption in daily functioning. Shares the core architecture of displaced priorities and continuation despite harm.
The most extensively validated behavioral addiction diagnosis. Shares core features with emerging conditions — impaired control, escalation, and persistence despite negative consequences — and has informed much of the broader behavioral addiction framework.
Patterns of sexual behavior or pornography use that become difficult to control and persist despite negative consequences. Assessment emphasizes functional impairment and loss of control rather than moral framing.
Compulsive shopping or spending urges that become difficult to control and lead to financial strain, relationship conflict, or distress. Often reinforced by mood regulation and online retail design.
Dysregulated online engagement across platforms. Overlaps with gaming disorder but spans broader drivers and behaviors, and shares features of compulsive use, mood modification, and withdrawal-like discomfort when restricted.
