Keep Your Poop in a Group

Why Fiber Fails to Impress—and Why That’s the PointFiber has a public relations problem. Unlike supplements or extreme diets, fiber does not promise instant transformation. Instead, it works slowly, predictably, and quietly. Because of that, people rarely notice it when it’s doing its job well. However, that very boredom is precisely why fiber matters.
When fiber intake is adequate, digestion functions normally, blood sugar behaves more consistently, and bowel habits stay predictable. As a result, there is no drama to post on social media. Consequently, influencers move on. Meanwhile, the science stays exactly where it has been for decades: fiber lowers disease risk over time.
That kind of quiet effectiveness may not sell products, but it saves lives.
“Fiber Isn’t Essential”—Why That Argument Misses the MarkTechnically speaking, fiber is not an essential nutrient in the classic sense. In other words, there is no disease caused solely by a lack of fiber the way scurvy results from vitamin C deficiency. Because of this, critics often stop the conversation there.
However, medicine does not ask only whether you survive. Instead, it asks whether your risk of chronic disease rises or falls over time. On that front, fiber consistently lowers the risk of colon cancer, improves glucose regulation, reduces constipation, and supports cardiovascular health. Therefore, while you can live without fiber, you do not age particularly well without it.
Protein Gets the Spotlight While Fiber Does the WorkAt the same time, nutrition conversations fixate on protein. Protein goals dominate podcasts, social media, and supplement aisles. Yet, in practice, true protein deficiency in the United States is rare, even among bariatric surgery patients.
In contrast, fiber deficiency is the norm. Roughly 92% of Americans fail to meet recommended fiber intake. As a result, constipation becomes common, long bathroom visits feel normal, and scrolling on a phone in the bathroom gets rebranded as “self-care.” Unfortunately, that normalization hides a real problem.
A Personal Lesson From Oats, Gas, and a Scorched DeskYears ago, I learned a fiber lesson the hard way. After deciding to increase my fiber intake quickly, I started eating steel-cut oats every morning during a busy meeting week. At first, everything seemed fine. Soon, however, my digestive system made it clear that it had not been consulted in this decision.
By the second day, bloating appeared. By the third day, office etiquette became questionable. Consequently, I lit a candle at my desk. Unfortunately, I turned my back, and papers caught fire. Although the flames were extinguished quickly, the scorch mark stayed for years.
That stain served as a reminder: fiber works best when introduced gradually. Your gut adapts over time. Confidence without patience, on the other hand, leads to unnecessary consequences.
Not All Fiber Works the Same WayUnderstanding fiber helps people stop fearing it. Soluble fiber, found in oats, barley, beans, lentils, psyllium, apples, and citrus, forms a gel in the gut. Because of this, it slows absorption, reduces glucose spikes, and lowers LDL cholesterol. Consequently, psyllium appears in clinical guidelines rather than influencer protocols.
Meanwhile, insoluble fiber focuses on mechanics. It adds bulk, speeds transit, and improves regularity. Importantly, this matters even more for people using GLP-1 medications, where slowed digestion often leads to constipation. In that setting, fiber is not optional—it is foundational.
Finally, fermentable fiber feeds gut bacteria. Beans, onions, garlic, asparagus, chicory root, and resistant starch nourish...
