Scientists reveal truth behind viral fibremaxxing trend

Scientists have shed light on the burgeoning health trend known as "fibremaxxing," which encourages individuals to meet or exceed daily fibre targets to transform their gut health.

The movement, which has gained significant momentum across social media throughout 2026, focuses on the mechanical and microbial benefits of plant-based roughage.

Experts suggest that adequate intake is essential for stabilising blood sugar, lowering cholesterol, and reducing the long-term risk of obesity and cardiovascular disease.

The benefits of "fibremaxxing"

Jennifer Lee, a scientist at Tufts University, suggests that as people seek ways to maintain their health during ageing, nutritional strategies are becoming increasingly vital. She warns that a deficiency can lead to poor dietary choices.

"If you're not consuming a lot of fibre, you're possibly consuming calories from other macronutrient groups, and they may be high in carbohydrates or fats, which can lead to weight gain," Lee noted.

She further cautioned that a lack of fibre may increase the risk for specific conditions, stating, "fibre deficiency may increase your risk for certain cancers, such as colorectal, breast, and prostate cancer."

Balancing soluble and insoluble intake

To achieve optimal results, researchers recommend a diverse intake of both soluble and insoluble fibres.

While soluble fibre, found in oats and avocados, manages glucose levels, insoluble fibre from whole grains and nuts aids digestive transit.

Experts suggest a ratio of two-to-one in favour of insoluble fibre. For those struggling to reach the recommended 22 to 34 grams daily through whole foods, supplements are considered a viable secondary option to bridge the nutritional gap.
