Overweight and obese individuals exhibit a gut microbiota profile characterized by higher abundance of Collinsella aerofaciens, Dorea formicigenerans, and Dorea longicatena compared to lean individuals.

Your gut bacteria profile differs if you are overweight or obese compared to if you are lean. Specifically, higher levels of Collinsella aerofaciens, Dorea formicigenerans, and Dorea longicatena are associated with higher body weight. Understanding these differences may help tailor dietary strategies for weight management.

Why this rating

Cross-sectional study design limits causal inference; however, the use of LEfSe analysis and sPLS adds statistical rigor to the association findings.
