A new dietary trend is emerging, focusing on increasing fiber intake. This trend, known as fibermaxxing, has gained significant attention on social media platforms like Instagram, with over 10,000 posts using related hashtags since the summer of 2025.

The shift towards fibermaxxing is a response to the significant decrease in fiber consumption in recent centuries, particularly with the advent of modern food processing. Many people, especially in developed countries, do not get enough fiber in their diets, disrupting the balance of microbes in the digestive system.

Further information on this trend and its implications for health can be found through Knowable Magazine, which has reported on the topic.
