Welcome Chewymom!
If you're interested in the regular version, I believe the major differences are (along with the whole grains and veggies of course):
-unlimited amounts of fruits & beans
-whole grain breads and bread products (whole wheat pitas, crackers, etc.) are allowed
-low fat tofu and soy milk are allowed
-very small amounts of other high fat products
on occasion (ie- nuts, avacado, tempeh, etc.)
-fruit juices are allowed, not just the whole fruits
Of course that's just what I've gathered through this discussion forum, I don't have the MWL book so others may know better
For what it is worth, I have lost 15 lbs since January first doing the regular program so it does work, just slower
