Basically, fibermaxxing is the practice of eating (or slurping in smoothie or beverage form) a high volume of fiber-rich foods every day. While it’s a newly trendy term, it’s not a new concept—it just means eating a generous amount of fiber daily, according to Berjis. So why the big fuss? Well, most of us eat too little fiber—as little as one-third the recommended amount. “Over the last few centuries, dietary fiber intake has decreased tremendously, leading to detrimental alternations in the gut microbiota. Such changes in dietary fiber consumption have contributed to the global epidemic of obesity, type 2 diabetes and other metabolic disorders,” reports a 2022 scientific paper published in = Microorganisms. (Yikes! Pass the granola!)
So fibermaxxing is a shiny new bow on a tried-and-true concept—eat your vegetables! “Most women need around 25–30 grams of fiber daily,” says Berjis. “To put that in perspective, that’s about what you’d get from a cup of raspberries, a hearty salad, a side of lentils, and a sprinkle of chia seeds. Spread it out through the day, and your gut will thank you.”
How Is Fibermaxxing Supposed to Help Me?
Fiber is like your body’s natural street sweeper. According to Berjis, it keeps digestion moving, supports healthy blood sugar levels, feeds the good bacteria in your gut and helps you feel satisfied after meals. “It’s one of those behind-the-scenes nutrients that does a lot of heavy lifting without demanding the spotlight,” she says. A healthy and steady diet full of fiber helps you avoid constipation, lower cholesterol, manage blood sugar, reduce bloating and even support hormone balance. Plus, research shows it plays a role in lowering the risk of heart disease, Type 2 diabetes and colon cancer.
