The term just means increasing the amount of fibre in your diet – something that doctors have been encouraging people to do for decades, for its benefits to the gut and elsewhere.
The main sources of fibre are pulses, like peas, beans and lentils, wholegrains, like brown bread and pasta, and, to a lesser extent, other vegetables, like sweet potato, sprouts and spinach, as well as nuts and seeds.
Here are the answers to all the questions you might have about this latest nutritional trend.
Fibre also attracts water into the bowels, which adds to volume, as well as softening the stool. The net effect is that people who eat more fibre will open their bowels more often and more easily.

And some studies suggest high-fibre diets are linked with lower rates of bowel cancer. The theory is that, in low-fibre diets, food takes longer to transit the bowel, letting it release substances that promote tumour growth.
How much fibre do you really need?
This is the big question. Official health advice is that we should have 30 grams per day, while the average UK intake is about 20 grams a day.
More modern diets have even less fibre, because people generally eat white bread, pasta and rice, instead of the whole-grain versions.
In a three week trial of a diet with 45 grams of fibre a day – based on the eating habits of people living traditionally in Papua New Guinea, people saw improvements in their blood cholesterol and blood sugar levels.
Most kinds of plant-based foods will have a mix of different types of fibre. Some fibre compounds are completely insoluble in water and so will pass through the gut practically unchanged – so their main benefit will be on bowel movements.
That’s because beta-glucans mix with water to form a viscous gel in the bowel. This binds with bile salts, made by the liver, which forces the liver to make more bile salts, using up cholesterol in the process.
Are there any downsides to fibremaxxing?
A sudden jump in fibre intake can cause bloating and discomfort, from gas released by gut bacteria that have gone from famine to feast.
“Discomfort will generally pass as your system gets used to having more fibre,” said Bridget Benelam, communications manager for the British Nutrition Foundation.

IBS is quite a variable condition; in some it causes constipation, while in others, diarrhoea is the chief problem.
Can you cheat with fibre supplements?
Because it is bulky, tablets can’t easily replace the amount of fibre in our diet that we should be eating. But a product called Fybogel is a powder that is mixed with water to make a drink.
This is a recommended treatment for constipation. But it contains only one kind of fibre – the viscous kind – and so doesn’t fully replicate the mix of different forms of fibre that you would get if you were having a mix of different plant foods.
Tips for boosting fibre intake
