A Dynamical Systems Model of Diet-Induced Gut Microbiota Interactions and their Impact on Host Metabolism

Abstract

The human gut microbiota influences host metabolism, with food being the key regulator of microbial composition and performance. This study generates a dynamical systems model to evaluate diet-induced interactions in the gut microbiota and their impact on host metabolic processes. According to the model, nonlinear differential equations are proposed and solved to model the population dynamics of important microbial groups that are affected by dietary factors like carbohydrates, proteins, and lipids. The model also includes metabolic results, such as short-chain fatty acids (SCFAs), which control host energy balance, glucose levels, and lipid metabolism. The model includes complex feedback interactions between microbial communities and host metabolic processes, and models a comprehensive set of food patterns, such as high-fiber, high-fat, and mixed. Stability analysis and bifurcation behaviour are used to determine if the gut ecosystem continues homeostasis or switches to dysbiosis. Overall, mathematical models show that mealtime satisfaction significantly impacts microbial equilibrium states, subsequent in numerous metabolic effects in the host. The Fiber-rich diets, in specific, encourage beneficial microbial development and improved metabolic profiles, although high-fat diets have been associated to decreased microbial diversity and metabolic dysfunction. The model is shown using clinical and experimental data from the present literature, representative its predictive potential for investigative diet-microbiotametabolism interactions. For reviewing the dietary interventions can encourage gut microbiota and increase metabolic health by using quantitative methods. The overall finding of this research study is significantly consequences related to personalized nutrition, and development of microbiome-based on therapeutics.
