Specific gut bacterial species (Akkermansia muciniphila, Bacteroides faecis, Bifidobacterium longum, Faecalibacterium prausnitzii) are negatively correlated with insulin resistance and dyslipidemia markers in postmenopausal women with obesity, suggesting a probiotic potential for metabolic health.

Focus on dietary patterns that support beneficial gut bacteria, such as those high in fiber and non-meat proteins. The study suggests that species like Akkermansia muciniphila and Bifidobacterium longum are associated with better metabolic markers, and their abundance is influenced by diet. While this study is observational, it supports the idea that dietary choices directly shape a gut environment conducive to metabolic health.
