Why is aspartame not allowed on Atkins?

Aspartame is not allowed on the Atkins diet primarily due to its potential effects on appetite and cravings. Some individuals may find that artificial sweeteners like aspartame can trigger a desire for sweet foods, which can undermine the low-carb principles of the Atkins program. Additionally, there are concerns about the potential health effects of consuming artificial sweeteners, prompting many followers of the diet to avoid them in favor of more natural options.
