Emerging evidence suggests that alterations in gut microbiota composition, known as dysbiosis, may significantly contribute to the development and progression of obesity. Research has highlighted distinct differences in the gut microbiota of obese versus lean individuals, with certain microbial profiles being closely linked to metabolic health. Probiotics and dietary fibers are well-documented for their roles in promoting gut health and modulating the gut microbiota, potentially influencing metabolic outcomes.

Probiotics, which are beneficial microorganisms, confer health benefits when consumed, and dietary fiber is known for its crucial role in gut health. Despite their potential, the specific effects of combined probiotic and fiber supplementation in obese individuals require further investigation. Conventional dietary interventions remain the cornerstone of obesity management; however, long-term success is often elusive due to challenges in sustaining weight loss and preventing weight regain. Therefore, exploring adjunct therapies such as probiotic and fiber supplementation offers a promising strategy to enhance weight management outcomes.

This study aims to evaluate the long-term effects of consuming a combined probiotic and fiber supplement over a 180-day period, specifically focusing on whether consistent use of the product affects gut microbiota diversity and overall metabolic health. Concurrently, a placebo-controlled study over three months will be conducted to observe short-term weight management outcomes. By comparing these two approaches, we aim to gather comprehensive data on both the immediate and sustained impacts of the supplementation.

Key objectives include assessing the influence of the supplementation on gut microbiota diversity, metabolic health, and various anthropometric parameters. The safety profile of the supplementation, alongside dietary interventions, is also a critical focus, particularly considering the potential underlying health conditions and polypharmacy often seen in obese individuals.

Conducting this single-arm clinical trial will provide valuable insights into the long-term efficacy and safety of probiotic and fiber supplementation. If proven effective and safe, this approach could be integrated into obesity management protocols, offering patients additional tools for achieving and maintaining weight loss. This study addresses a significant gap in current obesity treatment strategies and has the potential to contribute to the development of more effective and sustainable obesity management interventions.
