Move over keto and intermittent fasting – there’s a new nutrition trend gaining attention online, and it’s surprisingly simple. Known as “fibremaxxing”, the approach focuses on one thing: eating more fibre-rich foods throughout the day.
Unlike many fad diets that involve cutting out entire food groups or counting every calorie, fibremaxxing encourages people to add more fruits, vegetables, legumes, whole grains, nuts and seeds to their meals. Supporters say it can improve digestion, help with weight management and even boost overall health.
So what exactly is fibremaxxing, and could it be worth trying?
Fibremaxxing is a social media term used to describe intentionally increasing your daily fibre intake to maximise health benefits. While the name may be new, the concept is not.
Dietary fibre is a type of carbohydrate found in plant foods that the body cannot fully digest. Instead, it passes through the digestive system, helping to keep the bowels moving regularly and feeding the beneficial bacteria that live in the gut.
Health experts have long recommended eating plenty of fibre, but many Australians fall short of the daily target. According to dietary guidelines, adults should aim for around 25 to 30 grams of fibre each day, although many people consume considerably less.
The idea behind fibremaxxing is simple: build meals around foods naturally rich in fibre.
Common fibre-rich foods include:
Oats and wholegrain cereals
Lentils, chickpeas and beans
Fruit, particularly apples, pears and berries
Vegetables such as broccoli, carrots and leafy greens
Nuts and seeds, including chia and flaxseeds
Wholemeal bread, brown rice and quinoa
Fibre works in several ways. Some types absorb water and help soften stools, while others add bulk to waste moving through the digestive tract. Certain fibres also act as prebiotics, feeding healthy gut bacteria that play an important role in digestion, immunity and overall wellbeing.
A higher-fibre diet has been linked to a range of health benefits.
Improved digestion is one of the most noticeable effects. People who increase their fibre intake often report more regular bowel movements and fewer digestive complaints such as constipation.
Fibre may also help people feel fuller for longer, which can support healthy weight management. Because many fibre-rich foods take longer to digest, they can reduce the urge to snack between meals.
Research has also associated higher fibre intake with a lower risk of heart disease, type 2 diabetes and certain bowel conditions. Some studies suggest a diverse, fibre-rich diet may support a healthier gut microbiome, which is increasingly recognised as an important factor in overall health.
While fibremaxxing may sound like a health win, experts recommend increasing fibre gradually rather than dramatically overnight.
A sudden jump in fibre intake can cause bloating, gas and abdominal discomfort, particularly for people who are not used to eating large amounts of plant-based foods.
It’s also important to drink enough water. Fibre absorbs liquid, and without adequate hydration it can actually worsen constipation.
People with certain digestive conditions, including irritable bowel syndrome (IBS), may need to be selective about the types of fibre they consume and should seek personalised advice from a healthcare professional.
Unlike many nutrition trends that promise quick fixes, fibremaxxing is based on a well-established principle: most people would benefit from eating more fibre.
By adding extra fruits, vegetables, legumes and whole grains to everyday meals, many people can improve their digestive health while potentially supporting their heart, metabolism and overall wellbeing.
It may not be the most glamorous diet trend on social media, but when it comes to long-term health, fibre appears to have plenty going for it.
