Effect of Probiotics Supplementation on Gut Microbiota Composition and Weight Management in Overweight Individuals

Thesis Abstract

Abstract
The prevalence of overweight and obesity continues to rise globally, posing significant health challenges. In recent years, research has increasingly focused on the role of gut microbiota in weight management and overall health. Probiotics, live microorganisms that confer health benefits when consumed in adequate amounts, have gained attention for their potential impact on gut microbiota composition and weight regulation. This thesis investigates the effect of probiotics supplementation on gut microbiota composition and weight management in overweight individuals. Chapter 1 provides an introduction to the study, presenting the background, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of terms. Chapter 2 comprises a comprehensive literature review covering ten key aspects related to gut microbiota, probiotics, weight management, and their interplay. Chapter 3 details the research methodology, including study design, participant selection criteria, probiotics intervention protocol, data collection methods, and statistical analysis plan. Chapter 4 presents an in-depth discussion of the findings, analyzing the impact of probiotics supplementation on gut microbiota composition and weight management outcomes in overweight individuals. Various factors influencing the effectiveness of probiotics in modulating gut microbiota and promoting weight loss are explored, shedding light on potential mechanisms underlying these effects. The implications of the study results for future research and clinical practice are also discussed. In Chapter 5, the conclusion and summary of the thesis are provided, highlighting the key findings, implications, and limitations of the study. The overall impact of probiotics supplementation on gut microbiota composition and weight management in overweight individuals is synthesized, emphasizing the potential benefits and challenges associated with this intervention. Recommendations for future research directions and practical applications are proposed to further elucidate the role of probiotics in promoting healthy weight and gut microbiota balance. This thesis contributes to the growing body of knowledge on the relationship between probiotics, gut microbiota, and weight management, offering valuable insights into potential strategies for addressing the global burden of overweight and obesity. By elucidating the mechanisms by which probiotics influence gut microbiota composition and weight regulation, this study provides a foundation for further research and the development of evidence-based interventions to support optimal health outcomes in overweight individuals.
