The gut microbiota predicts and time-restricted feeding delays experimental colitis.

The etiology of inflammatory bowel disease (IBD) remains unclear, treatment options unsatisfactory and disease development difficult to predict for individual patients. Dysbiosis of the gastrointestinal microbiota and disruption of the biological clock have been implicated and studied as diagnostic and therapeutic targets. Here, we examine the relationship of IBD to biological clock and gut microbiota by using the IL-10 deficient () mouse model for microbiota-dependent spontaneous colitis in combination with altered (4 h/4 h) light/dark cycles to disrupt and time-restricted feeding (TRF) to restore circadian rhythmicity.

Dietary restrictions modulate the gut microbiota: Implications for health and disease.

The health benefits of carefully restricting the energy intake in a strategic manner whilst avoiding malnutrition are widely discussed. In the recent years, the great impact of the gut microbiota on its host has been clarified more and more. Since the gut microbiota produces a number of metabolites and molecules that can affect host metabolism, modulating it with dietary restriction can influence the health and the progression of disease of its host on various levels.
