In this Ask Dr. Shilpa, Cymbiotika’s Vice President of R&D takes a closer look at fibermaxxing, a term that has quickly moved from social media shorthand to mainstream wellness conversation. While the name may sound extreme, the idea behind it reflects a much larger gap in how most people approach daily nutrition.

Dr. Shilpa breaks down what fibermaxxing actually means, why it has gained traction right now, and where people often get tripped up when trying to increase fiber intake too quickly. With a focus on intention, consistency, and digestive tolerance, she offers a grounded perspective on how to approach this trend in a way that supports the gut rather than overwhelms it.

Fibermaxxing is having a moment online. From a scientific standpoint, what does the term actually mean, and how is it different from just “eating more fiber”?

“Fibermaxxing” has become a buzzword and is making waves on social media. Fibermaxxing might sound extreme, but it’s a catchy way of saying “eat a lot of fiber,” making a conscious effort to hit the recommended intake or even go beyond that. And I’m all for this trend.

The key difference between fibermaxxing and just casually eating more fiber is intentionality and consistency. It’s about making fiber a priority in your diet. Examples of how you can fibermax include adding extra veggies to pasta, sprinkling chia or flax seeds into smoothies and yogurt, choosing whole-grain versions of bread and pasta, and snacking on fruits or nuts, all in an effort to pack as much fiber as possible into each day.

It’s a trend that arose because most people aren’t getting nearly enough fiber. In fact, only about 7 percent of American adults meet their daily fiber needs, meaning 93 percent of us are falling short. Fibermaxxing is a response to this gap. Importantly, fibermaxxing means aiming for at least the recommended 25 to 35 grams per day for adults, or even a bit more. In short, fibermaxxing means consistently prioritizing fiber in your diet rather than treating it as an afterthought.
