I was just reading about this on the Atkins website yesterday and his words are something like: "The exact mechanism is not known, but aspartame appears to stall weight loss in some people. There are many cases where a person has stalled for weeks, but weight loss resumes when all aspartame is eliminated from the diet."

The same goes for caffeine, by the way. So it really is best to try to find a suitable substitute for you diet sodas if you can.

I've been enjoying regular Kool-Ade sweetened with Splenda! Makes me feel like a kid again!
