If you search for the term "opposite of anorexia" on Google, you aren't going to find a single, tidy Latin word that perfectly flips the script. Language is messy. Psychology is messier. Most people assume the "reverse" of a restrictive eating disorder is just overeating or obesity, but that’s a massive oversimplification that ignores the actual mental health mechanics at play.
Think about it.
Anorexia Nervosa is characterized by a distorted body image—specifically, seeing fat where there is none and a relentless drive for thinness. If we are looking for the true mirror image, we aren't looking at how much someone weighs. We are looking at the distortion. We are looking at people who look in the mirror, see a "small" or "weak" frame despite being incredibly muscular, and feel a pathological need to get bigger.
This is Muscle Dysmorphia. Or, as the fitness community and researchers like Dr. Harrison Pope have colloquially dubbed it: Bigorexia.
The Mirror That Always Lies
It’s a Tuesday morning at a high-end powerlifting gym. A guy is hitting a 405-pound squat. He’s got veins popping out of his delts and a chest that looks like it was carved from granite. Most people look at him with envy. But when he catches his reflection in the window, he doesn't see a beast. He sees a "lanky kid." He feels small. He feels invisible.
That is the core of Muscle Dysmorphia (MD).
While anorexia is a "restrictive" path, MD is often an "additive" one. You add weight. You add protein. You add hours at the gym. But the underlying engine—the body dysmorphic disorder—is identical. Research published in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) actually categorizes Muscle Dysmorphia as a specifier of Body Dysmorphic Disorder, though many clinicians argue it has more in common with Eating Disorders (EDs) than it does with OCD.
Honestly, calling it the "opposite" of anorexia is kinda helpful for a quick explanation, but it’s technically more like a twin sister. They both share the same DNA of dissatisfaction. They both involve a person becoming a prisoner to a number—whether that's the number on a scale or the number of inches on a bicep.

Not really.
BED involves losing control over food consumption. It’s often a coping mechanism for trauma or stress, but it doesn't necessarily carry the specific "body image inversion" that defines the anorexia-to-bigorexia spectrum. Anorexia is about control. Muscle dysmorphia is also about control. BED is often characterized by a perceived loss of control.
If we want to understand what is the opposite of anorexia in terms of the goal of the disorder, we have to look at the "Reverse Anorexia" phenomenon. In the 1990s, researchers began noticing bodybuilders who exhibited the exact same psychological traits as anorexics but in the opposite direction. They would wear baggy clothes to hide their "smallness." They would avoid social situations if they couldn't control their "macros." They would experience extreme anxiety if they missed a single workout.
The scale goes up, but the self-esteem stays at zero.
The Cultural Pressure Cooker of 2026
Social media hasn't just moved the goalposts; it's changed the entire game.
Back in the day, you had a few fitness magazines. Now? You have an endless scroll of "fitness influencers" who are literally paid to look inhuman 365 days a year. Many of these guys are using Performance Enhancing Drugs (PEDs) while claiming they are "natural." This creates a "baseline" for young men that is biologically impossible to achieve without chemistry.
When a 19-year-old kid looks at a filtered, lighting-optimized, pump-enhanced photo of a pro bodybuilder, he doesn't see a freak of nature. He sees the "standard." And when he fails to meet that standard, the "reverse anorexia" kicks in. He starts skipping classes to hit the gym. He spends $400 a month on supplements he doesn't need. He avoids his girlfriend because he’s "bulking" and doesn't want to eat out.
It’s an obsession that looks like "health" from the outside. That’s the danger.

If a girl stops eating, people notice. They intervene. If a guy spends four hours a day in the gym and eats nothing but chicken and broccoli, people give him a "fitness influencer" deal. We reward the symptoms of Muscle Dysmorphia because they look like discipline.
The Signs You’re Dealing with More Than Just a "Fitness Hobby"
How do you tell the difference between a dedicated athlete and someone suffering from the opposite of anorexia? It’s all about the interference.
A healthy athlete loves the gym. A person with bigorexia is terrified of not going to the gym.
- Social Withdrawal: They stop going to weddings, parties, or dinners because they can't track the calories or the food isn't "clean" enough.
- Physical Damage: Working out through torn labrums, stress fractures, or severe joint pain because the thought of losing "gains" is more painful than the injury.
- Anabolic Steroid Use: Transitioning from "healthy living" to using dangerous, unregulated substances just to add a few more pounds of lean mass.
- Mirror Checking: Or, conversely, mirror avoidance. Some will spend hours checking their reflection from every angle; others are so disgusted by their perceived "smallness" that they cover all the mirrors in their house.
Real Data and Clinical Perspectives
Dr. Roberto Olivardia, a clinical psychologist at Harvard Medical School, has spent decades studying this. He’s noted that while women are more likely to seek help for eating disorders, men with muscle dysmorphia often fly under the radar for years.
Studies show that about 10% of men who are "hardcore" gym-goers meet the criteria for Muscle Dysmorphia. That is a massive number. It’s not a fringe issue anymore. It's a growing epidemic fueled by a culture that equates masculinity with muscularity.
And let's be clear: this isn't just a "guy thing." While it's more prevalent in males, women in the "figure" and "physique" bodybuilding categories are increasingly reporting symptoms of MD. They want to be "lean and mean," and the fear of looking "soft" becomes just as paralyzing as the fear of looking "fat" is for an anorexic.
Recovery is Possible, But It’s Different
Treating the "opposite of anorexia" requires a specific touch. You can't just tell someone to "stop working out." That’s like telling an anorexic to "just eat a burger." It doesn't address the underlying dysmorphia.
Cognitive Behavioral Therapy (CBT) is currently the gold standard. It helps the individual identify the distorted thoughts—the "I look small" lies—and replace them with reality. Exposure therapy is also huge. This might involve going to the gym and not looking in the mirror, or skipping a workout and realizing the world doesn't end.

Nutritionists also play a role. They help transition the person from "obsessive tracking" to "intuitive eating," which is incredibly hard for someone who has spent years weighing their food to the gram.
Actionable Steps for Moving Forward
If you or someone you know seems to be spiraling into this "reverse anorexia" mindset, there are concrete things you can do. This isn't about giving up fitness; it's about reclaiming your life from an obsession.
Audit Your Digital Environment
Unfollow anyone who makes you feel "small" or inadequate. If an influencer’s content makes you feel like you need to buy a specific supplement or reach a certain body fat percentage to be "worthy," hit the block button. Your brain wasn't designed to compare itself to the top 0.01% of the world's physiques every 30 seconds.
Focus on Function, Not Aesthetics
Shift your goals. Instead of trying to get "bigger arms," try to get a stronger deadlift or improve your 5k time. When you focus on what your body can do rather than what it looks like, the dysmorphia starts to lose its grip. Performance is objective; "looks" are a subjective hallucination.
Diversify Your Identity
One of the hallmarks of muscle dysmorphia is that the gym becomes the only thing. You are "the gym guy." Start leaning into other hobbies. Paint. Code. Play an instrument. Volunteer. When your self-worth is spread across five different pillars, one pillar (like your physique) crumbling a bit won't take down the whole building.
Seek Professional Help
Don't just talk to a "coach" at the gym. Talk to a therapist who specializes in Body Dysmorphic Disorder (BDD) or Eating Disorders. They have the tools to help you rewire the neural pathways that are currently stuck in a loop of "not big enough."
At the end of the day, whether you're trying to be the thinnest person in the room or the biggest, you're still letting a mirror dictate your happiness. Real health is the ability to enjoy your life without being a slave to your own reflection.
