You don't have to worry about fat or calories with Atkins its the fact that you are eating minimal carbs that puts yr body into a ketogenic state which means that yr body burns yr fat for its fuel as it has no glucose from carbs to burn.... it basically turns yr body into a fat burning machine!
perhaps you should start a diary thread, then all your questions can be answered there, you will be able to find the info more easily, and you can post what you are eating, get some hints and tips from the successful peeps.
