“Manorexia” is a colloquial term for anorexia nervosa in men and boys. It is not a separate medical diagnosis. Men with anorexia have the same core disorder as women, involving severe food restriction, intense fear of weight gain, and a distorted relationship with their body. But the way it shows up in men often looks different enough that it gets missed by doctors, family members, and even the men themselves. Current estimates put the lifetime prevalence of anorexia in men at about 0.2%, compared to 1.4% in women, though the true number is likely higher due to widespread underdiagnosis.
Why Men With Anorexia Get Overlooked
For most of the 20th century, anorexia was defined partly by the loss of menstrual periods, a criterion that obviously excluded male patients. Even after that requirement was removed from diagnostic guidelines in 2013, the entire framework for detecting eating disorders remains built around how they present in women. The standard screening tools ask about wanting to be thinner or having a flat stomach. They rarely ask about wanting visible abs, a leaner physique, or more defined muscles, which are the goals men with anorexia more commonly describe.
This mismatch means men consistently score lower on eating disorder assessments, even when they are seriously ill. Their symptoms register as less numerous or less severe on paper, not because they are, but because the questions weren’t designed for them. On top of that, the cultural perception that eating disorders are a “women’s issue” creates a layer of stigma that makes men less likely to recognize their own symptoms or seek help. Shame, denial, and the fear of disclosing a condition they associate with femininity all contribute to longer delays before treatment. The gap between how many men have anorexia in the community and how many show up in clinics suggests that a significant number never get diagnosed at all.
How It Looks Different in Men
Women with anorexia typically pursue thinness. Men with anorexia more often pursue leanness. The distinction matters. Rather than wanting to shrink their body overall, men tend to restrict food in order to strip away body fat and reveal muscle definition underneath. Adolescent boys with anorexia are more likely to say they want visible “six-pack” abdominal muscles than a flat stomach. The restriction can be just as extreme, the weight loss just as dangerous, but the stated goal sounds different enough that people around them may not recognize it as an eating disorder.
Common behaviors include rigid dietary rules (often centered on high-protein, low-fat eating), compulsive exercise, fasting, and in some cases laxative misuse or purging. Body checking is frequent: repeatedly looking in mirrors, lifting shirts to inspect abdominal muscles, flexing, pinching skin to assess fat, weighing themselves compulsively, and constantly comparing their body to others at the gym or on social media. These habits share the same psychological roots as the body checking seen in women with anorexia, driven by perfectionism, deep body dissatisfaction, and a need for control.
The Overlap With Muscle Dysmorphia
Muscle dysmorphia, sometimes called “bigorexia” or “reverse anorexia,” is a condition where someone believes their body is too small or insufficiently muscular, despite often being well-built. It shares significant overlap with anorexia in men. Both conditions involve disordered eating, excessive exercise, obsessive body checking, and profound dissatisfaction with physical appearance. The key difference is direction: anorexia centers on the fear of being too large, while muscle dysmorphia centers on the fear of being too small. In practice, many men land somewhere in between, restricting calories to stay lean while also training obsessively to build muscle.
Some men with muscle dysmorphia use anabolic steroids, adhere to extreme high-protein diets, or take supplements or diet pills to manipulate their body composition. There is currently no diagnostic category that fully captures a muscularity-oriented body image, which means men whose eating disorder is driven by a desire for muscle definition rather than pure thinness can fall through diagnostic cracks.
Physical Health Consequences
The medical toll of anorexia in men is serious. Testosterone levels drop significantly, which has cascading effects. Low testosterone leads to decreased bone density, a problem that can persist even after weight is restored. Teenage boys with anorexia have measurably lower bone density than healthy peers of the same maturity level, putting them at risk for stress fractures and long-term skeletal weakness during a period when they should be building peak bone mass.
Beyond bone health, men with anorexia face the same constellation of complications as women: heart problems from electrolyte imbalances, muscle wasting, weakened immune function, cognitive difficulties, and organ damage in severe cases. Mortality data paints a stark picture. In one large study of patients treated for eating disorders, 15% of men with anorexia died prematurely, compared to 5% of women with the same diagnosis. Men with anorexia also had shorter survival times after the onset of illness than women. Being male and having anorexia were both independent risk factors for premature death.
What Drives the Risk
The idealized male body in Western culture is a V-shaped torso with a well-developed upper body and very low body fat, making the underlying muscle clearly visible. This image is reinforced everywhere: in films, fitness magazines, video game characters, action figures, and especially on social media, where “fitspiration” content showcases highly muscled, extremely lean physiques. Exposure to these images increases the likelihood that men will pursue extreme exercise routines or use steroids, and the relentless drive for muscularity can tip into anorexia or muscle dysmorphia.
For most men, the gap between their actual body and this cultural ideal is enormous and unbridgeable without extreme measures. Poor body image rooted in that gap has been linked to depression, disordered eating behaviors, and steroid abuse. The incidence of anorexia in men appears to be rising, likely fueled at least in part by the growing reach of social media and the constant visual comparisons it encourages.
Getting Appropriate Treatment
Treatment for men with anorexia follows the same general principles as treatment for women: restoring adequate nutrition, addressing the psychological drivers of the disorder, and rebuilding a healthier relationship with food and body image. Cognitive behavioral therapy is one of the most commonly used approaches, often combined with motivational interviewing to help patients who are ambivalent about recovery.
The challenge is finding treatment that accounts for the ways men experience eating disorders differently. A growing number of treatment programs now serve all genders or offer programming specifically designed for men, incorporating culturally responsive frameworks that acknowledge how muscularity ideals, masculine identity, and stigma shape the illness. Gender-affirming, weight-inclusive approaches that address the specific sociocultural pressures men face are becoming more available, though they remain less common than programs oriented toward female patients. Organizations like the National Association of Anorexia Nervosa and Associated Disorders (ANAD) maintain directories that allow users to filter for providers who specialize in treating men.
The biggest barrier remains getting men through the door in the first place. Because the disorder is still widely perceived as something that happens to women, many men spend years struggling before they identify what they are experiencing as an eating disorder, let alone seek professional help. Recognizing that food restriction driven by a desire for leanness and muscle definition is not “discipline” or “clean eating” but a potentially life-threatening condition is the first step toward closing that gap.
