Neither is Atkins a "low carb" diet by that measure. You count "net carbs", which exclude the low glycemic index stuff like fiber. One local Tex-Mex place went so far as to develope their own, made fresh on site, low net carb tortillas, which are in some ways tastier than the regular ones, with a 7 fold decrease in net carbs to less than 3 per tortilla. (And they only chage about a quarter extra for stuff made with them).
What is a '7 fold decrease'?
7 fold compared to what?
