Why everyone’s talking about fibremaxxing

If you’ve been scrolling through TikTok or keeping one eye on a wellness blog recently, you’ll have noticed the increasing presence of the trend ‘fibremaxxing’.

It sounds like the next thing in a long list of health food fads, but it actually does have some amazing benefits for your body if you give it a chance. Read on!

What is fibremaxxing and why is it trending right now?

It’s pretty straightforward: ‘fibremaxxing’ means making a conscious effort to get as much fibre as possible every day, mainly through everyday foods, and sometimes with the help of supplements.

Focus on fibre-rich staples like fruit, vegetables, seeds, beans, lentils, whole grains, nuts, etc. In the UK, most people consume only about 18g of fibre a day, well below the recommended 30g. That shortfall could be one reason you’re feeling sluggish or dealing with digestive issues.

Interestingly, Gen Z has embraced the fibremaxxing trend, turning what used to be ‘boring health advice’ into the latest wellness must-have. And it’s not just hype – growing research into the gut microbiome shows that your digestive health can influence much more than your digestion, from your mood and sleep to your immune system.

The UK Governments’ Scientific Advisory Committee on Nutrition reckons more fibre means less risk of heart disease, stroke, type 2 diabetes, and bowel cancer. Time to load up on prunes, chickpeas, and even a few roasted seaweed sheets – your gut will thank you later.

How fibremaxxing can help your body

Fibre is essential for a healthy gut. It’s a type of carbohydrate that the body can’t digest or absorb in the small intestine, so it passes into the large intestine largely intact, where it continues to have important effects. And it’s not just ‘roughage’ that helps move food through your system – fibre plays several other vital roles:

• Feeds your gut bacteria: Fibre acts as a prebiotic, feeding the beneficial bacteria that keep your gut microbiome balanced. This healthy ecosystem can have wide-ranging effects, from supporting immunity to influencing mood and helping the body’s natural cleansing processes.
• It supports digestion: Fibre aids digestion by adding bulk to foods and helping them move smoothly through the gut, reducing the risk of constipation. In the large intestine, it is fermented by gut bacteria to produce short-chain fatty acids, which support the gut lining and help lower inflammation.
• Balances blood sugar: Fibre slows the absorption of sugar into your bloodstream, helping prevent the spikes and crashes that can come from eating too much sugar. Even better, fibre – especially from whole, unprocessed foods – supports more stable blood sugar levels throughout the day.
• Keeps you fuller for longer: Fibre is a powerful ally for weight management because it helps curb your appetite. You can eat plenty of fibre without consuming too many calories; for example, a bowl of oats or a few seaweed sheets can keep you feeling full for hours while adding little to your calorie intake. Chewy, fibre-rich foods give your brain time to register satiety, reducing the risk of eating too much.

How to start fibremaxxing

The goal is smoother digestion, steady energy, and feeling fuller for longer. But don’t go all-in too fast – a sudden fibre surge can leave you bloated, gassy, or running to the bathroom. Like everything else, fibre-maxing is all about balance.

Don’t expect to feel amazing overnight by suddenly loading up on fibre. Instead, increase your intake gradually over a few weeks or months to let your body adjust. And always drink plenty of water to help your digestive system manage the extra fibre.

A good starting point is to add just one high-fibre ingredient to each meal rather than overhauling your entire diet at once. Keep enjoying the other healthy, fresh foods you already love. Simple swaps work wonders – think wholegrain bread or pasta instead of refined versions, or quinoa in place of white rice.

Variety is key. A diverse mix of fruits, vegetables, and grains feeds a broader range of gut microbes, strengthening the gut ecosystem that supports digestion, resilience, and overall wellbeing.

For snacks, reach out for nuts, legumes, or roasted seaweed – they’re high in fibre and far healthier than crisps or chocolate. And if you’re craving something sweet, fruit is your friend. Options like raspberries, prunes, or apples (with the skin on) are packed with fibre, without all the additives found in processed treats.

Fibremaxxing can actually be fun – especially when it means snacking on crispy seaweed thins! The movement has turned gut health into a social, feel-good trend that’s firmly part of modern wellness culture.
