Fibermaxxing trends on social media but experts warn against overdoing fiber intake.
In brief
Fibermaxxing trends on social media but experts warn against overdoing fiber intake. Most Americans eat far less fiber than recommended, but rapid increases can cause digestive issues and malnutrition. Originally reported by Straight Arrow.
Fibermaxxing Trend
Fibermaxxing is trending on social media where TikTokers and Instagrammers embrace taking self-improvement to the limit.
“Fibermaxxing is the latest in a social media fascination with 'maxxing,' or taking self-improvement to the limit.”
Fiber Shortfall
Most U.S. adults consume only about 5% of the recommended daily fiber, a gap linked to higher risks of heart disease and digestive issues.
“Researchers estimate that only about 5% of U.S. adults get the recommended daily amount of fiber.”
Fiber Benefits
Fiber helps lower cholesterol, manage blood sugar, and feed beneficial gut bacteria, supporting overall health.
“Its benefits extend beyond the bathroom: Certain types can help lower cholesterol, manage blood sugar and feed beneficial gut bacteria.”
Fiber Types
Soluble fiber dissolves in water, slows digestion, and helps manage blood sugar, while insoluble fiber adds bulk to stool.
“Soluble fiber dissolves in water. Some forms create a gel that slows digestion and helps you feel fuller for longer.”
Gut Health
Fiber feeds beneficial gut bacteria, producing short-chain fatty acids that support colon health and overall well-being.
“In the large intestine, different types of gut bacteria break down different types of fiber, producing substances called short-chain fatty acids.”
Fiber Recommendations
The National Academy of Medicine recommends 25 grams of fiber daily for women and 38 grams for men ages 19 to 50, with lower amounts for older adults.
“The National Academy of Medicine recommends 25 grams of fiber a day for women and 38 grams for men ages 19 to 50.”
Fiber Risks
Rapidly increasing fiber intake can cause gas, bloating, cramps, and for some, serious digestive complications like fecal impaction.
“Increasing intake too quickly can cause gas, bloating, cramps or changes in bowel movements.”
Fiber Supplements
Fiber supplements may help with constipation but do not replace vitamins, minerals, and plant compounds found in whole foods.
“Fiber supplements may help address specific problems, such as constipation, depending on the ingredient and the person’s needs.”
Fiber-Rich Foods
Whole grains, legumes, fruits, vegetables, nuts, and seeds provide the most fiber, with lentils and raspberries being high in fiber.
“A half-cup of cooked lentils provides about 8 grams of fiber, while a half-cup of raspberries provides about 4 grams.”
Slow Increase
Experts recommend gradually increasing fiber intake by about 5 grams per week to avoid digestive discomfort and ensure adequate nutrient intake.
“Ansari recommends increasing fiber intake by about 5 grams every week.”
Hydration
Drinking 2 to 3 liters of fluids daily for women and 3 to 4 liters for men helps fiber move through the digestive tract smoothly.
“She generally recommends about 2 to 3 liters of fluids a day for women and 3 to 4 liters for men.”
Fibermaxxing Caution
The 'maxxing' mindset can turn a healthy goal into an unhealthy push to eat more than your body needs, risking malnutrition.
“The idea shouldn’t be to max out our nutrition. It should be: How do we meet our needs in the best way to support our health?”
What Happens Next
Experts urge gradual fiber increases, hydration, and a focus on whole foods to improve health without overdoing it.
“You do not need to max to get all the benefits from fiber.”
The short version
Most Americans eat far less fiber than recommended, but rapid increases can cause digestive issues and malnutrition.
