Sniggle. Dr Atkins rules were simple enough to put on one sheet of paper. Dr Westmann about the same, with fewer rules in exchange for more limuted options.

Otherwise..... 3 cups of green leafy veg OR 2 Cups grern leafy veg plus 1 cup low carb veg

With allowed extras like cheese, olives etc that puts carbs at 20. Not 100.

Perhaps someone can put up a link to Atkins rules and dr W's.
