The rise of fiber-maxxing and protein-maxxing culture reflects a mindset that treats every meal as another opportunity for self-optimization, which can blur into unhealthy habits.
Log onto TikTok and there’s probably a woman who opens every video by announcing, gravely, how many grams of fiber she has consumed before noon. She’s “fiber-maxxing.” It’s 9AM. She has eaten chia seeds and lentils and a fistful of something leafy. She has logged it all, and she would like you to know. The comments are enthusiastic. The algorithm is pleased. And somewhere, a Pepsi executive is taking notes. This is the central paradox of the current health and wellness moment. We’re eating better information than ever, and yet something about the way we’re consuming it feels a little off.

Let’s Start With The Good Stuff: When Eating Healthy Becomes Performance
More than 90% of women and 97% of men don’t get the recommended daily intake of fiber. Fiber keeps your gut running and your heart healthy. It keeps your blood sugar stable and your colon grateful. One dietitian has called it the one nutrient that “can extend your life.” So when fibermaxxing, the trend of intentionally maximizing daily fiber intake, started flooding feeds, nutritionists cheered. Finally, someone was talking about chickpeas.
Protein-maxxing had its golden hour, and the calorie deficit content before that. There’s a real case that social media has done something the public health establishment spent decades failing to do. That is, to make people actually care about what they eat. According to McKinsey, nearly 30% of Gen Zers and millennials now report prioritizing wellness “a lot more” than a year ago, these generations more exposed to health-related content on social media than their older counterparts.
However, the line between “eating more fiber” and “performing eating more fiber online for an audience that rewards you for it” is increasingly blurry. The line between that and something more compulsive is blurrier still.
Always Optimizing: How Wellness Has Become An Extreme Sport
The wellness industry has a vested interest in ensuring you’re always optimizing, always one nutrient behind, always reaching for the next “-maxxing.” The wellness economy has doubled in size since 2013 and now outstrips the green economy, IT, tourism, and sports combined. It grows by convincing you that your current diet is insufficient.
What concerns researchers more than the lentil discourse, though, is where enthusiasm ends and disorder begins. Orthorexia nervosa is an emerging disordered eating pattern defined by an excessive focus on healthy eating that leads to psychological, social, and physical impairment. Increasing research highlights its prevalence and its association with social media use. It’s essentially an eating disorder that develops out of trying very hard not to have one. Research tracking Google searches shows a significant, sustained increase in people searching for “orthorexia” over the past twenty years, with investigators linking this rise directly to popular culture and increased social media use.
A systematic review found that social media addiction shows ties to both orthorexia and muscle dysmorphia symptoms, with researchers noting that these platforms simultaneously spread misinformation about nutrition and fitness while promoting idealized bodies. The uncomfortable implication is that the same platforms nudging people toward better gut health may be nudging something else too. It’s anxiety about food and the need for external validation of one’s eating habits.
Why It’s Important Not To Give Into “Maxxing” Culture
The “maxxing” suffix is doing a lot of work here. Maxxing implies a ceiling of correct eating that you should be straining toward. Registered dietitians have had to explicitly clarify that while most healthy individuals can benefit from the higher end of reference ranges for protein and fiber, upper limits still exist so you don’t exceed these ranges. The fact that this clarification is necessary tells you something about where the cultural pressure is pointing.
The conversation happening online about health isn’t inherently harmful. Bringing genuine nutritional awareness to a population that largely lacks it is a public good. But wellness culture that requires a public audience, that turns eating into content, that measures nourishment in grams displayed alongside follower counts, is something else entirely.
