Microbial ecology: human gut microbes associated with obesity

This 2006 study by Ley et al. analyzed the gut microbiota of obese and lean humans, revealing that obese individuals have a higher proportion of Firmicutes and a lower proportion of Bacteroidetes. Longitudinal data showed that weight loss through caloric restriction led to an increase in Bacteroidetes, suggesting a reversible

The Gut Microbiota and Ageing

This 2018 review published in Subcellular Biochemistry (PMID: 30779015) explores the evolving relationship between gut microbiota and aging, synthesizing research from model organisms such as Drosophila melanogaster, killifish, mice, and Caenorhabditis elegans. It highlights how age-associated changes in gut microbial composition may not only reflect aging but actively contribute to
