A nutrition coach shares 5 easy ways to start FiberMax in 2026

Last year, it felt like everyone was sleeping, breathing, and literally getting protein. But in 2026, textiles are poised to take center stage. At least some major food companies seem to think so. PepsiCo introduced new products to grocery store shelves this year, including fiber popcorn and potato chips, and Coca-Cola launched its own prebiotic soda in 2025, CNBC reports.

Fibermaxxing is so popular with users on TikTok that the platform has a FAQ under the search term with its own explanation. Many of the videos mentioning this hack say that eating more fiber can help you lose weight and increase your chances of having a healthy gut.

Fiber is an indigestible carbohydrate that the body cannot physically break down. When your body tries to digest fiber, “it just speeds up and activates your metabolism,” says Hunter Stoller, a certified nutrition and health coach.

“As a result, you’ll burn more calories and feel fuller for longer, because your body will try to break down what it can’t break down.”

Additionally, “your gut has a favorite food, and its favorite food is fiber,” celebrity nutrition expert Dr. Kellyanne Petrucci told CNBC Make It in 2024.

However, research shows that most Americans don’t get enough of this important nutrient. In fact, less than 10% of U.S. adults meet the recommended daily intake of fiber, according to a study presented at Nutrition 2021 Live Online.

According to the U.S. Department of Agriculture, adult women up to age 50 should consume 25 grams of fiber daily, and men in the same age group are recommended to consume at least 38 grams. According to Harvard Health Publishing, “Women and men over 50 should consume 21 grams and 30 grams per day, respectively.”

Typically, U.S. adults consume about 10 to 15 grams of total fiber each day, the Harvard University Health Blog reported in 2019.

Stoller, known as “The Health Hunter” to his many followers on social media, offers some easy ways to reach your daily fiber goals.

Eat more fruits and vegetables. Fiber-rich produce includes avocados, broccoli, leafy greens, berries, apples, and Brussels sprouts. Snack on foods with seeds, especially flaxseeds and chia seeds, Petrucci said. Stoller found that certain crackers made with flaxseed can contain up to 9 grams of fiber per serving. Nuts and beans are also good sources of fiber. Drink probiotic sodas that are high in fiber. “Some sodas contain anywhere from 3 to 9 grams of fiber per soda, which is incredible,” Stoller said. Get breads and bagels that are high in fiber. Consider adding a powdered fiber supplement to your smoothies or yogurt. It’s important to talk to your doctor about whether you actually need fiber supplements other than those found in food.

“Fiber is found in so many natural, real, whole foods that we as Americans don’t get enough of it every day,” Stoller says. “Simply read the labels at the grocery store and curate textile products based on what you like.”

When increasing your fiber intake, it’s important to drink more water, registered dietitian Mia Singh told Make It in an interview in July. Without proper hydration, Fibermax can cause constipation, diarrhea, abdominal pain, bloating and gas, Singh said.

Always consult your doctor before making any major changes to your diet.
