What is fibermaxxing?

Fibermaxxing is the trend of deliberately eating more fibre to support gut health, fullness and overall wellbeing. It focuses on whole-food fibre from vegetables, fruit, beans, lentils, wholegrains, nuts and seeds, rather than relying on supplements or powders. The idea is that most people fall short on fibre, so 'maxxing' it brings real benefits.

How much fibre should I eat a day?

General guidance is around 25 to 35 g of fibre per day for most adults, yet many people eat far less, often around 15 g. Fibermaxxing aims to close that gap. There is no need to go to extremes: very high intakes (50 g or more) can cause digestive discomfort, especially if increased too quickly.

What are the best high-fibre foods?

The best sources are whole plant foods: beans, lentils and chickpeas, wholegrains like oats and wholewheat, vegetables, fruit (especially with skins), nuts, seeds like chia and flax, and starchy vegetables. A varied mix throughout the day is more effective than relying on any single food.

Can you eat too much fibre?

Yes. Very high fibre intakes, particularly if increased suddenly, can cause bloating, gas and discomfort, and can interfere with mineral absorption at extreme levels. The fix is to increase fibre gradually and drink plenty of water. For most people, reaching 30 to 35 g a day is a sensible target.

Is fibre the new protein?

Fibre is having a moment, often called 'the new protein' because interest has surged alongside gut-health awareness and GLP-1 use. In reality both matter: protein preserves muscle and fibre supports fullness and digestion. The best approach pairs them, not chooses between them.

How do I increase fibre without bloating?

Increase it gradually over a couple of weeks rather than all at once, drink plenty of water, and spread fibre across meals instead of loading it into one. Whole foods are gentler than sudden large doses of fibre powders. If discomfort persists, ease back and build up more slowly.

Should I use fibre supplements?

Whole foods are the better starting point, since they bring vitamins, minerals and variety alongside fibre. Supplements can help fill a gap for some people, but skipping the ultra-processed fibre powders in favour of beans, vegetables, fruit and wholegrains is usually the more effective and satisfying approach.

Fibermaxxing: How to Eat More Fibre (the Right Way)

Fibre has quietly become the nutrient everyone is talking about. Dubbed “fibermaxxing” online, the idea is simple: most of us do not eat enough fibre, and deliberately eating more supports gut health, fullness and overall wellbeing. Here is what fibermaxxing actually means, how much you need, and how to do it without the bloating.

The short answerFibermaxxing means eating more whole-food fibre to hit around 30 to 35g a day, up from the ~15g many people manage. Focus on beans, lentils, vegetables, fruit, wholegrains, nuts and seeds. Increase gradually and drink plenty of water to avoid bloating.

Why fibre is having its moment

For years protein got all the attention. Now fibre is catching up, driven by two things: growing awareness of gut health, and the rise of GLP-1 medications, where fibre helps with fullness and digestion. Some now call fibre “the new protein”, though the truth is you want both.

The reason the trend has substance: most people genuinely fall short. General guidance suggests 25 to 35g a day, yet average intakes are often around 15g. That gap is what fibermaxxing sets out to close.

How much fibre do you actually need?

Aim for around 30 to 35g a day for most adults. There is no need to chase very high numbers like 50g or more, which can cause digestive discomfort. Consistency at a sensible level beats occasional extremes.

The best foods for fibermaxxing

The key is whole foods, not powders. Here is where the most fibre comes from:

Food group	Examples
Legumes	Beans, lentils, chickpeas
Wholegrains	Oats, wholewheat, rye
Seeds	Chia, flax
Vegetables	Broccoli, carrots, leafy greens
Fruit	Berries, apples, pears (with skin)
Nuts	Almonds, walnuts

Our high-fibre foods list ranks the best sources by fibre content, and our gut health foods guide shows how fibre and a healthy microbiome connect. If you want fibre and protein together, see our high-protein, high-fibre eating guide.

How to fibremaxx without the bloating

The most common mistake is doing too much, too fast. Follow these principles:

Go gradually. Increase fibre over a couple of weeks, not overnight.
Drink water. Fibre needs fluid to do its job comfortably.
Spread it out. Fibre at each meal is gentler than a single big hit.
Prefer whole foods. Beans and vegetables are kinder than sudden doses of fibre powder.

Don’t forget protein

Fibermaxxing works best alongside enough protein, not instead of it. Protein preserves muscle and fibre supports fullness and digestion, a powerful pair for weight management and gut health. Set your protein target with our protein calculator, then build meals rich in both.

The bottom line

Fibermaxxing is a rare trend with real substance: most people genuinely under-eat fibre, and closing that gap supports fullness, digestion and gut health. Aim for around 30 to 35g a day from whole foods, build up gradually with plenty of water, and pair it with protein. Start with our high-fibre foods list to see where the biggest wins are.
