I definitely eat much less than I did on sw and I didn't calorie count there either. In fact I find that as little food as half a chicken breast and a nibble of cheese is enough for lunch so I don't worry about calories I might consume since I know I'm eating less and I'm full. Yay.
Atkins and paleo studies I've read show that people tend to eat less when in ketosis so average calories come out at an even equivalent to a calorie controlled diet, just without the feeling deprived!
And we get to eat cheese! Yay!
