The first time I did Atkins back in '94 I didn't know better and got away with one cup like you have yours and still lost weight fast but as the years went by I found that that one cup kept me craving sugar all day long so this time it's out. You'd be way better off eating a protein-rich breakfast, it will give you sustained energy and keep your mind alert, or try taking two capsules of L-tyrosine on an empty stomach. I read a study that said that only the first cup of coffee gives a mental boost, the rest will just raise your adrenaline (stress reaction = fat storage) and will end up making you feel more tired later. So if you can't quit, limit yourself to ONE cup but follow it with an "Atkins" type breakfast.

About fats, Dr. Atkins actually writes in his book, referring to the Induction period: "I want you to be totally, shockingly unafraid of fat during these two weeks. Fat is much more ketosis-inducing than protein." Ketosis eliminates hunger and cravings...

If you haven't read the book, I strongly recommend that you do so you can avoid mistakes that might hinder the results of the diet or even your health. Dr. Atkins' diet has been blamed for a lot of negative things but I'm sure it's because of the way we choose to do it, ignoring a lot of the great recommendations he gives.
