I know there’s no calories, but should I restart, since I know its not something people generally have whilst fasting.
one sip is probably okay.. a general rule of thumb is to avoid zero calorie sodas with artificial sweeteners like that to avoid the insulin spike that they cause, but if it helps you get through the fast (and you would give up without it) especially if you just started fasting then it is okay
It all depends on the drink. I’ve noticed that some zero calorie fruity drinks will still have some natural sugars that’ll trigger insulin and it also makes them about 5-10 calories a can instead of zero. It even says it on the label. Whereas with coke zero there shouldn’t be any natural sugars so it should be generally okay to drink on a fast in the same way black coffee is.
Probably an unpopular opinion but i’d rather an imperfect fast than no fast at all. I just couldn’t completely cut out the Diet Coke. I don’t drink coffee, diet coke has always been my “ahhhh morning caffeine” drink. So while yeah, the aspartame is not great and probably does trigger an insulin response, it’s still better than not fasting at all. I am not particularly sensitive to artificial sweeteners though, they’ve never caused me any cravings, other people get hungry or crave more sweets when they drink diet sodas.
I drank black coffee in my fasts before. And though I never counted it to break my fast, it did have only one ingredient.
Be easy on yourself. If it says 0 calories then you’re fine. Just don’t start consuming it on the daily or it could have an effect of your results (but I’m not 100% sure of this, I just wanted to say you shouldn’t feel as though you need to start over)
I’m trying to not be dismissive of people’s concerns, but a pinch of common sense wouldn’t sometimes hurt I think.
While I consider it possible that artificial sweeteners have a negative effect on the purpose of fasting, the body would have to be pretty screwed up if it couldn’t quickly eradicate the tiny potential spike in insulin that could occur.
AFAIK artificial sweeteners can induce an insulin spike even if they are zero calories.

Insulin can also be triggered by smell:
