The fiercest fights over bodies are rarely about health alone; they are contests over who is authorized to define normalcy, to discipline deviation, and to translate anatomy into moral worth and political order.
At a Glance
- A Socialism 2026 session framed anti-fat norms and the diet industry as “body fascism” that disciplines “Black fat flesh,” linking size-policing to broader systems of governance.
- The argument situates BMI and obesity discourse within a history of eugenics, racialized standards, and actuarial tools that migrated into medicine as common sense.
- “Body fascism” has antecedents in interwar movements that fused idealized physiques with national virtue and social control; the modern usage critiques similar logics in health culture.
- Public health still leans on BMI as a quick surrogate for fatness even as critics document its limits and racialized origins; this tension fuels current disputes over stigma versus care.
What Harrison Argued and Why It Resonates
At the Socialism 2026 conference in Chicago, author Da’Shaun L. Harrison argued that the diet industry and contemporary health norms do not merely sell weight loss; they police “Black fat flesh,” providing ideological and administrative scaffolding for what they called “entire systems of governance.” The provocation is deliberate: without a population to discipline, Harrison contended, there would be no BMI categories to sort us by, no “obesity epidemic” to mobilize policy around, and no medical or scientific apparatus organized to manage fatness as a problem set. Framed this way, weight management is not a neutral intervention but a civilizing project—one that stigmatizes certain bodies in order to authorize regulation, surveillance, and markets that claim to “fix” them.
The claim struck a nerve because it connects everyday experiences—doctor’s visits, workplace wellness metrics, algorithmic recommendations for dieting products—to a political theory of the body. If the language of risk, responsibility, and self-control maps neatly onto long-standing tropes about race, class, and deservingness, then health talk becomes moral talk, and moral talk becomes governance. The argument is not that health behaviors don’t matter; it is that the social meanings attached to body size do disproportionate work in assigning blame, extracting compliance, and legitimating interventions that routinely miss the upstream causes of ill health.
How BMI and Anti-Fat Norms Became “Common Sense”
To understand the critique, start with the tools. Body mass index—weight divided by height squared—was never designed as a diagnostic; it was a population-level statistic developed by the Belgian mathematician Adolphe Quetelet in the 19th century and later absorbed into insurance tables and clinical routines. Scholars have documented how size-based ideals, validated through “standard weight” tables and later BMI cutoffs, entered medicine along pathways shaped by eugenics, demography, and actuarial convenience rather than individualized physiology. When a tool built for sorting populations becomes the yardstick for judging persons, error bars turn into identities. The consequences are practical (misclassification across sexes, ages, and ethnicities) and cultural (the reification of a narrow ideal as medical truth).
Public health institutions still rely on BMI because it is inexpensive, fast, and reasonably predictive at scale; the World Health Organization defines overweight and obesity by BMI and acknowledges it as a surrogate for adiposity, often supplemented by waist circumference and other measures. That institutional inertia coexists with a growing literature on BMI’s limitations and on how weight stigma itself drives harm—avoided care, stress physiology, even iatrogenic bias. Harrison’s thesis presses further: when those limitations overlap with racialized assumptions—about whose bodies are “undisciplined,” whose appetites need control—size becomes a proxy through which older hierarchies persist under the banner of science.
“Body Fascism”: A Term With a History
“Body fascism” is not casual name-calling; it descends from scholarship on interwar movements that made the trained, athletic body a symbol of national vigor and political rectitude. In British Union of Fascists iconography and practice, the disciplined physique was a civic ideal and a method of social pedagogy; the body was both message and mechanism of control. Contemporary critics repurpose the term to analyze how modern institutions—fitness culture, wellness branding, and aspects of clinical practice—elevate a narrow body ideal as proof of responsibility, credibility, and worth, marginalizing those outside it. The throughline is the political work performed by aesthetics: organizing people around a model body, and then treating divergence as a failure of character or citizenship.
This does not require goose-stepping to matter. When employers tie incentives to weight cutoffs, when media moralizes food choices, when clinical encounters are reduced to BMI targets irrespective of context, a familiar civics of discipline reasserts itself. The point of the Harrison argument is not that every diet plan is authoritarian; it is that a culture which naturalizes the disciplining of certain bodies—particularly Black fat bodies—reproduces power through medicalized language that pretends to be neutral.
Race, Stigma, and the Politics of Health
The racial dimension is not an add-on; it is central to the literature Harrison taps. Scholarship has traced how fatphobia’s intellectual genealogy intersects with racialized aesthetics and anxieties dating back to the 18th and 19th centuries; those preferences later cohered into medicalized standards through eugenic projects and actuarial sorting. Parallel work in public health policy underscores that obesity’s burden falls disproportionately on Black, Indigenous, and other communities of color, yet sustained policy attention to structural drivers—food access, environmental exposures, labor conditions—lags behind behaviorist prescriptions aimed at individuals. The result is a double bind: stigmatized bodies are urged to self-correct in environments designed to produce the very outcomes for which they are blamed.
Stigma is not a soft variable. It changes health-seeking behavior, alters stress pathways, shapes clinical decision-making, and justifies punitive or neglectful policy. When critics argue that anti-fat governance “anchors” systems of control, they are pointing to how categorization hardens into allocation: who gets insured at what rate, whose pain is taken seriously, who is screened for what, who is coded as noncompliant. BMI may be a crude measure; stigmatization built on that crudeness is precise in its effects.

Where the Real Disagreement Lives
There is no dispute that high adiposity correlates with risk at the population level; nor is there serious debate that BMI, used bluntly, is an imperfect proxy. The live argument is about primacy and frame. One camp holds that the fastest route to better health is still aggressive risk management—measure, message, motivate—while steadily improving tools to individualize care. The other insists that until we disarm the moralizing machinery around body size, we will continue to medicalize the consequences of policy while ignoring its causes. Harrison’s intervention lands firmly in the latter: change the political economy of bodies—the incentives, the definitions, the markets—and the health conversation can stop deputizing citizens to police one another.
Consequences for Medicine, Policy, and Culture
For clinicians, the implication is practical: treat BMI as a screening flag, not a verdict; pair it with better phenotyping, attend to weight stigma as a modifiable harm, and interrogate how bias enters routine care. For policymakers, the target is upstream: invest in food systems, built environments, and labor protections that make health the path of least resistance; measure success by reduced disparity, not by aggregate BMI shifts alone. For culture-makers and the wellness economy, the challenge is to decouple virtue from leanness—to market health behaviors without rehearsing hierarchies of worth.
Harrison’s language is confrontational by design, but the substance aligns with a mature body of critique: tools like BMI gained authority through history as much as through physiology, and the governance of bodies has always been a political project as well as a medical one. If we want health metrics to serve care rather than control, we must decide what we are measuring for—and whom our measurements empower.
