Your social media feed is buzzing with a new wellness trend: fibermaxxing. Between the smoothie recipes and gym selfies, influencers are sharing their high-fiber meals and tracking their daily totals. But unlike some fleeting health fads, this one has our registered dietitians nodding in approval.
The concept is simple—maximize the fiber in your diet. But before you load up on beans and broccoli, here’s what you need to know about doing it safely and effectively.
“I love fiber—it’s essential for digestion, satisfaction, and even cholesterol and blood sugar management,” says Melissa Jaeger, a dietitian and Head of Nutrition with MyFitnessPal (10). “Fibermaxxing is an accessible way to focus on increasing fiber in your diet and logging in MyFitnessPal can help you spot which foods have the most fiber.”
So, What Is Fibermaxxing?
“In general, it is increasing your daily fiber intake by increasing your intake of high fiber foods. I recommend gradually increasing your fiber intake and fluid intake at the same time to avoid any side effects,” says Jaeger (9). The approach focuses on reaching (but not dramatically exceeding) the recommended daily fiber intake of 25-38 grams (1). Women should aim for about 25 grams daily, while men should target 38 grams (1).
Despite fiber’s importance, most Americans fall short. The average person consumes only 10-15 grams of fiber per day—well below recommendations (2). That gap makes fibermaxxing less about following a trend and more about meeting basic nutritional needs.

How Fibermaxxing Works
Increasing your fiber intake delivers several science-backed benefits for your body. First, fiber promotes regular digestion and can help decrease bloating by adding bulk to stool and supporting healthy gut bacteria (3). This is why many people notice improved digestive comfort when they eat more fiber-rich foods.
Beyond digestion, fiber plays a key role in managing blood sugar levels. Soluble fiber slows the absorption of sugar, helping prevent blood sugar spikes after meals (4). This makes it particularly valuable for people managing diabetes or prediabetes.
Fiber also supports heart health by helping to lower cholesterol. Soluble fiber binds to cholesterol particles in your digestive system and helps remove them from your body, which can reduce LDL (bad) cholesterol levels (5).
Where to Find Fiber in Your Diet
Adding more fiber doesn’t require special supplements or expensive products. The best sources are whole, minimally processed foods you probably already eat—or can easily add to your routine.
According to Jaeger, whole fruits and vegetables top the list, especially when you eat the skins and seeds where appropriate. Apples with the peel, berries, pears, broccoli, Brussels sprouts, and carrots all pack substantial fiber (6). Legumes like lentils, black beans, and chickpeas are fiber powerhouses, with some varieties offering 15 grams or more per cup (6).
Whole grains provide another excellent source. Swap refined grains for options like oatmeal, quinoa, brown rice, and whole wheat bread (6). Seeds deserve special mention—just two tablespoons of chia seeds contain about 10 grams of fiber, while flaxseeds offer similar benefits (6).
How to Try Fibermaxxing Safely at Home
Ready to boost your fiber intake? Here’s how to do it without digestive distress:
- Increase fiber gradually by adding about 5 grams per day to your current intake. This gives your digestive system time to adjust and minimizes gas, bloating, constipation, or diarrhea that can occur when fiber increases too quickly.
- Drink plenty of water throughout the day—fiber needs adequate hydration to move smoothly through your digestive tract (11). Start by adding one high-fiber food to each meal, such as berries on your breakfast oatmeal, a side of vegetables at lunch, and beans in your dinner. Track your intake using MyFitnessPal to ensure you’re reaching recommendations without overdoing it.
Most people can safely increase their fiber intake, but check with your doctor if you have a digestive condition like inflammatory bowel disease or diverticulitis, as some conditions require specific fiber guidelines (7).
Frequently Asked Questions (FAQs): Fibermaxxing
Can you eat too much fiber?
Yes. Consuming significantly more than 38 grams daily can cause digestive discomfort and may interfere with mineral absorption (1). Stick to recommended ranges unless your doctor advises otherwise.
What’s the difference between soluble and insoluble fiber?
Soluble fiber dissolves in water and helps lower cholesterol and blood sugar, while insoluble fiber doesn’t dissolve and promotes regular bowel movements (3). Most high-fiber foods contain both types.
Will fibermaxxing help with weight management?
Fiber increases satiety, helping you feel fuller longer, which may support weight management efforts (8). However, it’s not a magic solution and works best as part of an overall balanced diet.
How long does it take to see benefits from increased fiber?
Many people notice improved digestion within a few days to a week, though cardiovascular benefits like cholesterol reduction may take several weeks to months of consistent intake (5).
Should I take fiber supplements instead?
Whole food sources are preferable because they provide vitamins, minerals, and other beneficial compounds along with fiber (1). However, fiber supplements may help some that struggle to meet needs through food alone.
The Bottom Line
Fibermaxxing isn’t just another fleeting wellness trend—it’s a practical approach to meeting nutritional guidelines that most people already fall short on. By gradually increasing your intake of fiber-rich whole foods like fruits, vegetables, whole grains, and seeds, you can support your digestive health, blood sugar management, and cholesterol levels. The key is taking it slow, staying hydrated, and listening to your body as you work toward that 25-38 gram daily target.
