Aspartame in Crystal Light....

[ScottyB28]

Will the aspartame in Crystal Light knock you out of ketosis?

It can, but I doubt it will. Aspartame is made up of two amino acids. It has, mg per mg, just as many calories in it as regular sugar. However, it's 200x as sweet as regular sugar and thus is used 200x less than regular sugar.

So, depending on how much you drink/eat, it could but you'd need to ingest a lot of it.
