Thanks Itsajoyful, for your response. And it couldn't have been more timely...just the other day I hit a wall...I was so tired, all of the time. So I cut down on some of the cardio, and I feel much better!

And, even though I don't want to go CKD just yet, I did find the <a href="http://www.users.voicenet.com/~petrizzi/fitness/ckdcalc.html">CKD Parameter Calculator</a> to be of help. After entering my specific information, it told me that I can average 2500 calories a day on "ketogenic" days. So, no more guilt!

Thanks again!
