Sweetener syrups are now available to use in place of sugar and you can also make your own using a powdered sweetener in the same way you'd make a sugar...
I do not use either of those artificial sweeteners as lab tests indicate these still trigger an insulin response despite being 0 calorie. As an example I used to eat a chocolate candy with maltitol that had such an effect on insulin I could have used it as a sleeping pill. I later learned several artificial sweeteners and sugar alcohols may be no or low calorie but they can be as bad or worse than sucrose for triggering an insulin response.
