The gut microbiome in obesity.

Area of Science:

• Microbiology
• Metabolism
• Human Health

Background:

• Obesity is a global epidemic with increasing prevalence.
• The human gut microbiome is increasingly recognized for its role in host metabolism and inflammation.
• Advances in sequencing technology have facilitated deeper understanding of the gut microbiome's influence.

Purpose of the Study:

• To review current research on the associations between the gut microbiome and obesity.
• To explore mechanistic studies on the role of gut microbes in obesogenic physiology.

Main Methods:

• Literature review of observational studies linking gut microbiome composition to obesity.
• Analysis of mechanistic studies investigating the functional roles of gut microbes in metabolic processes related to obesity.

Main Results:

• Numerous studies demonstrate significant associations between gut microbiome alterations and obesity.
• Mechanistic studies highlight pathways through which gut microbes impact host energy balance, inflammation, and appetite regulation.

Conclusions:

• The gut microbiome is a significant factor in obesity development and maintenance.
• Targeting the gut microbiome presents a potential therapeutic strategy for obesity management.
