I agree with Teri and Paleo, and I'll add that sometimes the calories matter more from certain foods than others due to differences in 'satiety'. Cheese and heavy cream are an example, because many people find it easy to overdo it on these foods. There's no way I could eat 500 calories worth of... say, pork chops in one sitting, but I could easily eat 500 calories worth of pizza toppings (ie mainly cheese.) I also could probably eat close to 500 calories worth of whipped cream.

If you're starting out on Atkins, you don't have to worry about the calories too much *if* you follow the other induction rules: cheese limited to 4 oz, cream limited to 2-3 fl oz, etc.

Since you're talking about concern over bingeing tendancies, you'll want to pay attention to your habits and reactions toward certain foods, and see if the above applies to you. As always, YMMV.
