Any diet worth it's salt would begin first with the concept of physical fitness, and I don't see Atkins doing that.

You didn't read the book. Exercise is covered quite extensively.

I don't believe that Atkins places first importance on fitness. Point me to the sections in his book where you can confirm my error, and I'll be glad to concede your point. Atkins covers physical fitness and the primary importance of it in a cursory way, IMO.
