Another probable explanation would be that the Rebaudioside A derived from the stevia that was used in this study is metabolized by the gut microbiota to steviosides and then transformed into glucose and a molecule of steviol; the final metabolite of stevia is the glucose that is absorbed in the intestinal epithelium [50], a situation that could generate the increase of glycaemia and therefore the elevation of GIP, insulin, and the HOMA index generating insulin resistance and causing an effect similar to sucrose. Here, INS is linked to Insulin resistance.
