I don't know about ya'll...but, I know [from experience] that a couple Diet Sodas [w. Aspartame] will stall my weight loss. Diet Rites [w. Splenda] and Home-Made Beverages [w. Stevia] do not stall me.

IIRC, Aspartame does not taste "like Sugar." It has a strong chemical taste, which is barely tolerable (initially) and takes getting used to. It works by acting on the brain, causing your brain to believe it is sweet. It has no natural sweetness.

Other Artificial & Natural sweeteners (Splenda & Stevia) are truly sweet (don't act on the brain to feign sweetness) and thus don't appear to cause the same effects [on me at least.]
