Energy balance

Members of the Bacteroidetes phylum exhibit high metabolic flexibility and genomic diversity, allowing them to dynamically adjust gene expression and substrate utilization (dietary vs. host glycans) in response to environmental changes, which influences host energy harvest and metabolic health.

Focus on dietary diversity, particularly fiber, to support a resilient and metabolically flexible gut microbiome. Avoid extreme, restrictive diets that may deplete beneficial bacterial strains like Bacteroidetes, as their ability to adapt to different substrates is key to metabolic health. Recognize that probiotic effects are strain-specific and not guaranteed by phylum-level changes alone.

GoodQualifiesHIGH confidence
Members of the Bacteroidetes appear to be metabolically highly flexible... B. thetaiotaomicron switched its gene expression patterns towards enzymes capable of metabolizing host-derived mucus glycans... The ability of these bacteria to take on a kaleidoscope of glycans makes them ideally suited to an omnivorous host with a variable diet.

Why this rating

The paper is a comprehensive review citing multiple high-impact studies (metagenomics, gnotobiotic mice, human cohorts), though it notes inconsistencies in human observational data.
