Fibremaxxing – the latest buzzword for TikTokers talking about the health benefits of fibre

Posted on 31st July 2025

The term "fibremaxxing" – and its American spelling "fibermaxxing" – has become a big talking point in recent weeks largely through news media picking up on the growing interest on TikTok in the dietary importance and health benefits of fibre.

There's a big community of TikTokers who've been advocating more focus on fibre for some time and sharing tips and eating ideas – and news media have picked up on the catchy "maxxing" label as the latest in the wake of the likes of "sleepmaxxing" and "looksmaxxing".

It's a TikToker called Pamela Corral who's inspired the recent wave of headlines about it after viral videos of her high-fibre chia seed puddings – which she credits with reducing her bloating.

"The most underrated macronutrient"

Influencers and nutritionalists are posting on social media to raise awareness about the importance of fibre and how it's often overlooked in comparison to other nutrients.

Health and fitness content creator @skyyconoboyy describes fibre as being "the most underrated macronutrient" and thinks it's not getting enough recognition in the fitness industry compared to protein and fats.

You only have to look at the numbers to see there's significantly more talk about protein on TikTok – 2.4 million posts on #protein compared to 400,000 posts on #fiber and #fibre.

But, according to @fiberchina, "If everyone cared about their fibre intake as much as you guys care about protein intake we will be a lot healthier as a society". She advocates a fibre-first diet and explains how fibre aids digestion, regulates blood sugar levels, supports weight loss, feeds gut bacteria, and lowers cholesterol.

30g of fibre a day

Health organisations and government guidelines recommend a daily intake of 30g fibre and people on TikTok are showing how to achieve this.

NHS surgeon Dr Karan Rajan, who has 7m followers across his socials, regularly posts about the importance of fibre and fibremaxxing tips. He also has a weekly gut health email newsletter. In this TikTok he shares "easy ways to fibremax" with common kitchen cupboard foods that are high in fibre. He's also produced a "crib sheet" showing how to get 5g of fibre from foods in different fibre groups.

@fiberchina advises against taking fibre supplements to hit the 30g daily goal as "fibre is one of the easiest nutrients to get just by eating real food. Think berries, beans, chia seeds, veggies, and oats. You don’t need powders or pills when you build your meals around plants. Your gut, blood sugar, and energy levels will thank you."

"We should all be fibremaxxing!"

The increased focus on fibremaxxing is opening up conversations about fibre among everyday people who are agreeing about fibre being as important as the likes of protein and sharing stories about the impact of increasing their fibre intake in their own diets.

The kinds of things people are saying include:

• "We should all be fibremaxxing!"

• "Yay! We're back on fibre! So over the protein police 😂"

• "I like the fact that people are beginning to speak up on the importance of taking fiber rich foods"

• "Ugh yes. The amount of high protein meals I see without even a whisper of a vegetable, grain, or fruit involved 😫"

• "OMG! I think about this all the time, the amount of protein content I see and they never mention fiber 😫"

• "No one is protein deficient.. fiber is important for your colon.. 👍"

• "Heard someone say fibre needs the PR team protein has 😂"

• "Averaging about 35 grams of fibre a day and not worrying about the protein atm honestly has changed the game for me"

One TikToker did a 30g fibre for 30 days challenge earlier this year, vlogging supermarket trips to buy high-fibre foods and reporting an increase in her energy levels and reduction in sugar cravings.

High-fibre recipes on TikTok

There are lots of recipe ideas and inspiration on TikTok for people trying to increase their dietary fibre intake.

At the moment stewed apples are popular as a topping for breakfast bowls, snacks and desserts because of the gut health benefits of cooking apples.

One of the advocates is @thrivewithcandice, who posts healthy recipes and content about "nontoxic living". She explains the science of how cooking apples releases pectin – a soluble fibre which feeds all the beneficial bacteria in our gut – and serves hers with Greek yoghurt for a "gut healthy high protein breakfast".

This TikToker recommends stewed apples on chia seed pudding – combining the soluble fibre of the apples with the insoluble fibre of chia seeds which she says are both needed for gut health.
