The gut microbiome in obesity

Obesity is worldwide epidemic given its rapid growth in global prevalence. Among the risk factors contributing to obesity, human gut microbiome recently emerges with unprecedented intimacy in host metabolism and inflammation. With the advances in sequencing technology, more and more detailed understandings towards the intricate relationships linking gut microbiome and obesity have been continuously disclosed. Herein, we review studies resolving associations between gut microbiome and obesity, and then mechanistic studies tackling the roles played by gut microbes in obesogenic physiology.
