Gut and Insulin Responses to High vs. Low Glycemic Diets
What Is Insulin Resistance? – Dr. Berg (YouTube link ) In [1], this study demonstrates that while LGL ( low glycemic load) and HGL ( high glycemic load) diets do not significantly alter the overall diversity of the gut microbiome, they induce specific changes in microbial taxa , metabolic pathways, and CAZyme activity . The LGL diet promotes microbial metabolism of fiber and phytochemicals, associated with favorable metabolic outcomes, while the HGL diet enhances pathways linked to dietary additives and insulin resistance. These findings highlight the role of dietary carbohydrate quality in modulating microbial metabolism and its downstream effects on host health, particularly in the context of insulin sensitivity and chronic disease risk. Detailed Insights Dietary Impact on Microbial Composition : The lack of significant changes in overall alpha and beta diversity suggests that short-term dietary interventions may not drastically reshape the gut microbiome's struc...
