Energy balance
Exercise frequency positively correlates with gut microbial diversity and the abundance of beneficial bacteria (e.g., Faecalibacterium, Roseburia) that produce short-chain fatty acids (SCFAs), enhancing intestinal barrier function.
Regular physical activity boosts gut bacterial diversity and increases beneficial bacteria that produce SCFAs, which strengthen the gut barrier. Aim for daily exercise to support a healthy microbiome.

Daily exercise increases gut microbial diversity ... with a Firmicutes enrichment microbiota: Clostridiales, Roseburia, Lachnospiraceae, and Erysipelotrichaceae by producing more SCFAs which may increase the expression of tight junction proteins in colon epithelia to heighten the resistance of the intestinal barrier.
Why this rating
Cites studies showing associations, though causality is complex due to dietary confounders.

More from this paper
- Dietary patterns (specifically high-fiber/plant-based vs. high-fat/animal-protein) rapidly and reproducibly alter gut microbiota composition and function, shifting enterotypes and metabolic output within days.Strong
- Gut microbiota composition is not a single optimal state but a personalized ecosystem shaped by early-life factors (birth mode, feeding), age, and ongoing lifestyle variables (diet, exercise, BMI), where health is defined by functional balance rather than specific taxonomic abundance.Good
