Thesis Abstract

Abstract
The human gut microbiota has emerged as a key player in the regulation of host metabolism and overall health. This thesis aims to explore the effects of gut microbiota on obesity and metabolic health in adults. The research begins with a comprehensive review of the existing literature on the role of gut microbiota in metabolic disorders, including obesity, insulin resistance, and metabolic syndrome. Through a systematic analysis of relevant studies, this thesis identifies key factors influencing the composition and function of gut microbiota and their impact on host metabolism. The methodology section outlines the research design, participant recruitment, and data collection methods used in this study. Utilizing advanced sequencing techniques, the composition of gut microbiota in adults with varying degrees of obesity and metabolic health is analyzed. The results reveal significant differences in the diversity and abundance of gut microbial species between individuals with obesity and those with a healthy metabolic profile. Moreover, specific microbial taxa are associated with metabolic parameters such as body mass index, insulin sensitivity, and lipid profile. The discussion section delves into the potential mechanisms through which gut microbiota influence host metabolism. It explores the role of gut microbial metabolites, such as short-chain fatty acids and bile acids, in modulating energy balance and metabolic pathways. Additionally, the impact of gut dysbiosis on systemic inflammation, gut barrier function, and adipose tissue metabolism is discussed in the context of metabolic disorders. In conclusion, this thesis highlights the intricate interplay between gut microbiota, obesity, and metabolic health in adults. By elucidating the mechanisms underlying these relationships, this research contributes to a deeper understanding of the role of gut microbiota in metabolic disorders. The findings underscore the potential therapeutic implications of targeting the gut microbiota for the prevention and management of obesity and related metabolic conditions. Further research in this field holds promise for the development of personalized interventions that harness the gut microbiota to improve metabolic health in adults.
