I have a few comments that I save uo for times like this.
Like when someone tells me I should stop doing Atkins, I've already lost enough, blah blah blah, I tell them that it is not a diet, it's not just for weight loss,I'm in it for life, etc.

My favorite is when people hear "no-carb" when you say "low-carb." There's a HUGE difference people!

Those people who mention anorexia should be handed a dictionary, and a sample daily menu of the average LC'er.
