It seems to me that by far the best option would be to limit consumption of both added sugars and artificial sweeteners.
Personally, I've done low-carb diets where things with sugar are almost entirely off-limits, minus a small amount of fruit, and whatever small quantities of sugar are present in non-starchy vegetable. During these diets, I've tried them with and without artificial sugars. Those artificial sugars would be consumed in either diet drinks/sodas, or with coffee. I had the occasional desire to consume something with lots of carbs/sugar, but I can't say it was any strong with artificial sugars than without.
If anything, for me, the artificial sugars worked to satiate the desire for something sweet.
First I was on strict diet, less than 10 grams a day sugar first two weeks, then restrict to less than 20 grams and gradually increase... Then one day I had craving for chocolate, got one with malittol - first a little chunk, then a bit more, a bit more... Then I had troubles in the loo, more troubles, more troubles, and... switched back to normal chocolate.
It did not worked for me. But it could the next time...
You shouldn't swear off artificial sweeteners because of the stigma around them, especially since there's such an abundance of research around them debunking all the purported ill effects (except for maybe laxative effects and bad reactions in phenylketonurics) – you can have your artificially sweetened cake and eat it too.
