Called the new gut-health glow-up, “fibermaxxing” is a nutrition trend based on boosting your daily fibre intake to help with weight loss or weight management, optimise digestion, and lower the risk of chronic diseases.

The TikTok hashtag #fibermaxxing has been used over 157 million times – according to video generator platform SendShort – and has been getting lots of attention on Instagram and YouTube.

While experts often criticise social media wellness trends, this one has won many health professionals’ seal of approval. Below, two experts explain why and how to tap into this trend for its many benefits.

Fibre is a type of complex carbohydrate found in plant foods that does not get digested or absorbed in our small intestine.

“Common sources include whole grains, like brown rice, oats, quinoa and barley; legumes, like chickpeas, beans and lentils; fresh and dried fruit; vegetables; and nuts and seeds,” says Denise Tam, a Hong Kong-based holistic nutritionist.

Seaweed and air-popped popcorn are good sources, too, she adds, though these are less commonly thought of.
