They’re not all one category; some artificial sweeteners cause an insulin response and some do not. This would make sense as to why it can lead to diabetes; your body is constantly getting signals to release insulin to break down sugar, but then there’s no sugar. Eventually your body “learns” to not produce as much insulin in the presence of all sweeteners, and that’s diabetes in a nutshell. I’d be interested to see if these studies hold with sweeteners like Stevia that don’t produce an insulin response.
