Hi there,

A coupleof reasons for Dr A suggesting no aspartame.

1. For some people it does cause slow down in weight loss
2. It has negative side effects for others (upset tummy or headaches)

Atkins prefers splenda as the artificial sweetner to use. It's more about the saftey/ health side of things than the effect it will have on weight loss.

if you have no trouble with it then it is fine to carry on.
