Fiber maxing: why fiber is your most underrated nutrient (and how chicory can help)
Share
You're probably not getting enough fiber. And you're not alone.
If you're on TikTok, you've surely come across the term "fibermaxxing": the intentional practice of maximizing daily fiber intake. This isn't just a fleeting trend. It's a response to a very real and well-documented nutritional problem.
A study presented at the Nutrition 2021 conference, based on data from over 14,600 individuals from the US National Health and Nutrition Examination Survey (NHANES), found that approximately 93% of American adults do not consume the recommended amount of fiber. Another study, published in 2017 in the American Journal of Lifestyle Medicine, found an almost identical figure: 95%.
Specifically, the recommendation is generally between 25g per day (women) and 38g per day (men). Most people consume about 15g. That's a shortfall of almost half.
Good news: closing this gap doesn't require a complete dietary overhaul. It mostly requires knowing the right sources — and easily adding one or two to your routine.
Why fiber truly deserves your attention
Fiber is often associated with "bowel movements" and that's where the understanding stops. This is a mistake: its role goes far beyond that.
1. It nourishes your gut microbiota
There are two main families of fiber: insoluble fiber (which adds bulk to stool) and soluble fiber, some of which — like inulin — are called "prebiotic." A prebiotic fiber is not digested in the small intestine: it arrives intact in the colon, where it serves as food for good bacteria.
A study published in Food Quality and Safety documented this effect: the fermentation of inulin in the colon promotes the growth of beneficial bacteria like Bifidobacterium and Lactobacillus, while reducing certain less desirable bacterial populations.
2. It can improve your digestive regularity
A clinical study cited in the same journal observed that 12g of inulin per day, for 4 weeks, significantly increased populations of good bacteria and improved stool consistency in adults with mild constipation.
3. It's linked to a better cardiometabolic profile
An analysis published in 2025 in Frontiers in Nutrition, based on NHANES data from 1999 to 2018, established a link between higher fiber intake and a reduction in cardiovascular mortality in adults with metabolic syndrome.
4. It plays a role in satiety
Soluble fibers like inulin form a gel when they come into contact with water, which slows gastric emptying. In other words: they can help you feel full longer.
How to consume more fiber daily
No need to count every gram. A few simple habits are enough to make progress:
- Add a source of fiber to every meal: legumes, vegetables, fruits with skin, whole grains.
- Go gradually. Too rapid an increase can cause bloating. Most sources recommend gradually increasing over 2 to 3 weeks.
- Drink enough water. Soluble fiber needs water to do its job properly.
- Look into concentrated prebiotic fibers, such as chicory inulin, which allow you to add a significant amount of fiber without completely changing your plate.
This is precisely where chicory comes in.
Chicory: one of the most concentrated sources of inulin available
The chicory root (Cichorium intybus) is recognized as one of the richest plant sources of inulin, the prebiotic fiber par excellence. This is not a recently discovered trendy ingredient: it has been used as a coffee alternative since the 19th century, long before its digestive benefits were scientifically understood.
Each cup of Happy Chicory provides 1.2g of inulin fiber. This is not the 12g used in some clinical studies on constipation — and we don't claim it is. But integrated into a daily routine, this 1.2g adds up: one cup in the morning, one in the afternoon, and you start to concretely reduce the gap with the recommended 25 to 38g per day, without calculating effort, without swallowing supplements, just by replacing a drink you already consume.
This is exactly the angle of fibermaxxing: not a dietary revolution, but simple, repeated additions that, when combined, make a difference.
A product for every moment of your day
At Happy Chicory, we offer several ways to integrate this fiber source into your routine, depending on what you're looking for.
Craving the taste of coffee, without the caffeine? Our 100% chicory products (Chicory Espresso and Instant Chicory) are prepared with the same equipment and offer a taste reminiscent of coffee — roasted, caramelized, with a familiar slight bitterness. The result: you can drink it in the morning or in the evening, without affecting your sleep or heart rate.
Want to keep some coffee, but differently? Our Coffee-Chicory Blend (20% coffee, 80% chicory) is designed for that. You keep a small energy boost, but the caffeine content is intentionally limited to avoid peaks and crashes later in the day. A simple way to gradually reduce your coffee consumption, while continuing to enjoy inulin fiber with each cup.
In both cases, you add 1.2g of inulin fiber per cup to your routine — whether you choose to cut caffeine completely or go easy.
The final word
Fiber is one of the most scientifically documented nutrients — and one of the most neglected in the current North American diet. Filling this gap doesn't require changing everything: just adding reliable sources, a little each day. Chicory is one of them, with the added bonus of being 100% natural and caffeine-free.
