Effects of High Dietary Fiber Intake on Glucose and Lipid Metabolism in Obese Individuals

Abstract

Obesity has emerged as a pressing public health concern worldwide, characterized by disrupted glucose and lipid metabolism. This dysregulation often results in severe conditions, including insulin resistance, type 2 diabetes, non-alcoholic fatty liver disease, and cardiovascular disorders. Besides genetic predispositions, unhealthy eating habits play a pivotal role. Recent research underscores the benefits of dietary fiber, an enzyme-resistant carbohydrate, in enhancing glucose and lipid metabolism. By incorporating fiber-rich foods into diets, individuals can mitigate these metabolic disturbances and work towards better health outcomes. comprehensively examines the impact of high-fiber diets on glucose and lipid metabolism in obese individuals, exploring the intricate physiological and molecular pathways involved. Dietary fiber alters the gut microbiota composition, fostering the production of short-chain fatty acids (SCFAs). These SCFAs bolster intestinal barrier function, enhance insulin sensitivity, and refine energy metabolism. Consequently, embracing a high-fiber diet emerges as a scientifically grounded and clinically valuable nutritional approach for managing obesity and associated metabolic disorders.
