You don't have to count calories on Atkins. You can eat a lot and you will still lose weight. You can eat as much bacon, hamburger, cheese, eggs, and so on, as long as you keep your body in ketosis you will burn fat and burn it fast. Being in ketosis lowers cholesterol even with all that bad fat. If you are not in ketosis on a high protein diet then it is important to watch the quantity and to eat lean meat, and also watching the fats. This is what I have learned from reading the Atkins book. I'm recommending that you read it if you want to do this kind of diet.
