Oh, if you last did Atkins in the 90s, you'll want to pick up the newest book from like 2010-2011. It's alot more inclusive than the old New Diet Revolution!! I have that book too, back when it said to eat like meat, eggs and 1 cup of cooked veggies and 2 cups of lettuce each day. Not any more!! Much more liberal and lots more foods/recipes offered.
If you'd like to know what Atkins is like NOW, make sure to check out their offical site at atkins.com. You'll be amazed! I know I am! (I did Atkins for a short time in '03 when the old book was still the one everyone had)
