It usually starts innocently enough: a green smoothie here, a “what I eat in a day” reel there, a hashtag promising to help you eat clean, feel light, and finally get on top of your health. For many of us, it feels less like content and more like motivation.

But a growing body of research is raising a quieter, less comfortable question: what happens when the pursuit of “clean” eating stops being about health, and starts becoming something else entirely?

The research catching up with what clinicians are already seeing

Recent studies on “clean eating” content and social media have found a consistent pattern. People who regularly engage with clean-eating hashtags on Instagram show higher levels of orthorexic behaviour – an excessive, rigid preoccupation with eating “correctly” that can crowd out flexibility, spontaneity, and eventually, wellbeing itself.

Visual, image-heavy platforms appear to carry the strongest effect. Research comparing platforms has found that TikTok, Instagram and YouTube are more strongly linked to orthorexic patterns than text-based platforms – which makes sense, given how much of this content relies on aesthetics: the beautifully plated bowl, the “after” body, the implied discipline behind it all.

One recent study found that among 14-24 year olds, 55% had heard of clean eating, and 41% said they’d be willing to try it. Separately, research on adult women found that following clean eating recommendations was associated with higher levels of restrictive eating behaviour consistent with orthorexia nervosa. Health and fitness content in particular – even when it doesn’t mention weight loss directly – showed the strongest association with increased risk.

Why “healthy” content can be the hardest trap to spot

Orthorexia nervosa isn’t yet a formal diagnosis in the DSM-5, which is part of what makes it so easy to miss – in ourselves, in our clients, and in the people we love. Unlike more recognisable disordered eating patterns, orthorexia hides in plain sight, dressed up as discipline and self-care.

That’s precisely what makes clean eating content so difficult to challenge. Nobody worries about a friend who’s “just trying to eat healthy.” Families often celebrate it. Followers reward it with likes and comments. The rigidity is reframed as virtue, right up until food rules start dictating social plans, triggering distress when “imperfect” meals happen, or quietly narrowing someone’s life.

The warning signs worth knowing

In practice, some of the signs I watch for include: rigid or moralistic thinking about food (“clean” vs “bad”), significant anxiety or guilt after eating something outside self-imposed rules, a shrinking list of “safe” foods, social withdrawal linked to food avoidance, and a preoccupation with food quality that takes up a disproportionate amount of mental space and time each day.

It’s worth noting the research isn’t all one-sided. Social media can also be a genuine source of connection and recovery support for people navigating disordered eating – the same platforms that amplify harmful content can host communities of people offering encouragement, education and accountability. The issue isn’t social media itself; it’s the type of content, how much of it we consume, and how uncritically we absorb it.

What actually helps

If any of this feels familiar – for you, or someone you care about – a few starting points:

Notice the feeling, not just the content. Pay attention to how you feel after scrolling clean-eating or fitness content: inspired, or anxious and inadequate? That feeling is data.

Question the “after” photo. Curated content rarely shows the rigidity, anxiety or isolation that can sit behind a picture-perfect meal.

Diversify your feed. Actively follow accounts that model flexible, non-diet-focused relationships with food and body.

Reach out early. Disordered eating patterns are far easier to shift before they become entrenched. A conversation with a psychologist doesn’t require a diagnosis – just a sense that something isn’t sitting right.

The takeaway

“Clean eating” isn’t inherently dangerous, and wanting to look after your health isn’t something to feel guilty about. But when the pursuit of the “perfect” diet starts to feel less like a choice and more like a rule you can’t break, it’s worth pausing and asking who — or what — is really setting that rule.

If this resonates with you or someone in your life, I’d encourage you to reach out. Support is available, and a healthier relationship with food and body is absolutely possible.
