If you are familiar with south beach paleo is closer to that. In general, 100% organic veggies, lots of eggs, grass fed beef, free range chicken, no peanuts but other nuts are ok in moderation, sweet potatos in moderation as well, fruit is fine as long as you dont go nuts.
The big differences are with unnatural things. No artificial sweeteners, which means no diet soda or sugar free candies etc.
if you are familiar with atkins and south beach it is the same general idea but really stresses the natural part where atkins and south beach have gotten rich off of selling items filled with articicial shit. advocates of the diet say you should stay away from most oils as well, coconut oil and olive being the best.
My standard day - 2 egg omelet with bacon and peppers for breakfast. paleo chili or leftovers for lunch (lots of oven baked wings) Steak and sweet potato fries, pot roast with carrots and onions, sausages in tomato sauce, etc for dinner
