I've noticed that people react very differently when you mention "Atkins" vs "low carb/watching my carbs/etc". Unfortunatley, the Atkins name has become synonymous with the High protein, high fat, 0 carb misconception that runs rampant in the low fat, high carb world we live in.

I usually just tell people I am watching my carbs and leave it at that. No one seems to want to argue that point.
