Diet‑Modulated Gut Microbes Predict BMI and Risk
A recent study published in Nature has identified gut bacterial species linked to BMI and health status in a large cohort of nearly 35,000 individuals. Researchers developed a scoring system to rank these bacteria based on their association with health outcomes and dietary patterns. The findings suggest a significant relationship between gut microbiome composition and metabolic health, highlighting the need for further exploration of these microbial species.
- ▪The study involved 34,694 participants from five US and UK cohorts.
- ▪Researchers created the 'ZOE Microbiome Health Ranking 2025' to assess the health associations of various bacteria.
- ▪Healthy individuals tend to have a higher abundance of favorable bacteria compared to those who are overweight or ill.

Published in late 2025 in the journal Nature, a study of nearly 35,000 people represents a major step up in scale for human microbiome research: It identified and ranked gut bacterial species — both previously known and uncharacterized — that are associated with BMI, clinical health status, and dietary patterns.To better understand how the gut microbiome is linked to diet and metabolic health, the researchers developed a score that ranks bacteria according to their association with good or poor health.
