Okay Marsad, I need to steal your idea... may do a rhyming thread to get my count up! ;-) I'm Scotland as well just a bit further north in Aberdeen.
I'm on Dukan and the few people I've told go "huh?" Then when I start to tell them what its like, they just go "OH RIGHT - Atkins!" So yes, I think saying "low-carb" is probably the safest bet.
Wine is a no-no on Dukan, so maybe I should just start Atkins.... ha, ha!!
