Why ‘Fibermaxxing’ Is Suddenly Everywhere — and How Much Fiber You Actually Need | Blue Shield of California

by Beth Trimarco

If your social media feed is suddenly full of bean bowls, chia pudding and towering salads, you’re not imagining it. ‘Fibermaxxing‘ — the idea that loading up on fiber is the key to better health — is the latest viral nutrition trend, with influencers calling it ‘the protein of 2026.’

Angie Kalousek Ebrahimi, certified nutrition coach and senior director of lifestyle medicine at Blue Shield of California, understands why fiber is getting attention, but she cautions against turning any one nutrient into a fad or trend.

“I’m old enough to remember the carb-load era,” said Kalousek Ebrahimi. “People ate heaping plates of pasta because we were told more carbs meant more energy. It seems ridiculous today. No nutrient works in isolation. Fiber is essential, but it’s not a solo act.”

What exactly is fiber?

Fiber — or what our grandmothers called roughage — is a carbohydrate found in plant foods that the body doesn’t fully digest. It moves through the digestive system to support gut health, regulate blood sugar, lower cholesterol and help us feel full.

We need both types of fiber: soluble fiber for blood sugar and cholesterol, and insoluble fiber for digestion and regularity. UCSF Health recommends 25-30 grams a day — yet most Americans only get about 15 grams.

“Fiber works best when it’s part of a larger nutritional conversation,” said Kalousek Ebrahimi. “It’s not meant to crowd out other nutrients — it works alongside them.”

Getting real about health trends

While it’s tempting to try the “latest and greatest,” many wellness trends swing too far. In today’s era of optimization, eating can turn into a numbers game — but overemphasizing any one nutrient leads to imbalance. Protein supports muscle and metabolism; fiber aids digestion and blood sugar control; and fruits, vegetables, whole grains and healthy fats deliver vitamins and minerals that keep everything running smoothly.

“Your body needs a team, not a single star player,” she said. “When you balance your macronutrients, your body thanks you with more energy, fewer crashes and less hunger.”

Kalousek Ebrahimi’s approach to fiber is simple and sustainable: eat six to eight servings of fruits and vegetables a day and you’ll naturally hit your target — no tracking required. She also recommends folding fiber-rich foods into meals you already enjoy: add beans or lentils to soups and salads, choose whole grains, or toss extra vegetables into whatever you’re cooking.

And for anyone tempted to triple their fiber intake overnight, she offers some practical advice: go slow.

“Your gut microbiome needs time to adjust. If you jump from low fiber to high fiber in a day, your gut will absolutely let you know,” she said. “And truly, overload isn’t necessary. Anything over 35 grams a day isn’t doing much for you.”

The bottom line? Fiber deserves its moment — just not at the expense of balance. Nutrition trends come and go, but steady, balanced eating lasts. When you plan for protein-, fiber- and nutrient-packed foods together, you’re supporting your long-term health — not just the next viral moment.

Angie’s Recipe for Lentil and Potato Stew — with a Twist

Ginger sweet potato and coconut milk stew with kale and lentils is super flavorful, beautiful and hearty. It’s the perfect winter meal with loads of fiber and micronutrients.

Ingredients

• 1 TBSP coconut oil
• 1 medium yellow onion (diced)
• 1/2-1 tsp dried chili flakes
• 1/2 tsp ground coriander
• 1/2 tsp ground cumin
• 1/2 tsp ground turmeric
• 2-inch piece fresh ginger, peeled and minced
• 3 cloves garlic, peeled and minced
• salt and ground black pepper, to taste
• 1.5 lbs sweet potatoes, peeled and diced into 1-inch pieces
• 1/2 cup dry brown lentils, picked over
• 4 cups vegetable stock
• 13.5 oz can full-fat coconut milk
• 1 bunch kale, stems removed and leaves chopped (about 4 packed cups of chopped kale)
• Chopped cilantro, extra chili flakes, lime wedges, and/or nigella seeds for garnish

Instructions

1. Heat a large, heavy-bottomed soup pot over medium heat
2. Add coconut oil to the pot and let it melt
3. Add onions and sauté, stirring occasionally until translucent and soft (about 5 minutes)
4. Add chili flakes, coriander, cumin and turmeric, sauté until fragrant (about 1 minute)
5. Add the ginger and garlic and cook for another minute
6. Add a pinch of salt and pepper
7. Add the sweet potatoes and lentils, stir to coat in the spices
8. Add the vegetable stock and stir, scraping up any browned bits on the bottom of the pot
9. Season liberally with salt and pepper.
10. Place the lid on top of the pot and bring to a boil
11. Once the stew is boiling, lower the heat to a simmer until the sweet potatoes are almost falling apart, and the lentils are tender (about 30 minutes)
12. Add the coconut milk and kale to the pot and stir
13. Place the lid on top and continue to simmer the stew until the kale is wilted and bright green (about 3-4 minutes)
14. Bring the stew back up to a strong simmer and do a taste check: add more salt, pepper, chili etc. to taste
15. Serve hot with optional chopped cilantro, extra chili flakes, lime wedges to squeeze on top and nigella seeds
16. Ready in about an hour!

Recipe Notes

• Coconut milk is naturally sweet, and so are sweet potatoes. I like to balance things out with a lot of dried chili, but add to whatever spice level you wish.
• Chard or mustard greens would also be delicious in place of the kale.
• For extra protein, add chicken or tofu.
