Raised insulin levels are much more complicated than we once thought. You can get an insulin response from artificial sweeteners just swished in your mouth and spat out. Solution, eat real food when you can
I think I first saw it referenced on an old edition of 'The Complete Guide to Sports Nutrition' by Anita Bean
I'm aware of no RCT or even epidemiological research to suggest that NAS causally mediates insulin response.
I appreciate that you posted a comment instead of just downoting. The fucking ignorant downvoting prick squad is a key reason that I mostly gave up commenting here.
