I am a relatively new practitioner of the paleolithic diet with a few questions.
Shortly after eliminating breakfast cereals and bread from my diet, my head got
foggy and I noticed a fruity taste in my mouth that reminded me of something
I've experienced when a fever breaks.  I'm assuming this is ketosis.

Is ketosis commonly experienced when one adopts a paleolithic diet, or should
I be making a greater effort to incorporate more fruits and vegetables in my
diet?  If ketosis is a common feature of a paleolithic diet, does one adapt to
it?  This foggy feeling and difficulty concentrating is getting old.

Also, I'm an avid strength trainer.  I had always believed that carbohydrates
were the preferred fuel source during intense exercise.  If I'm in ketosis, I'd
assume that I wouldn't have sufficient carbohydrates for to-failure weight
training, which is apparently the rationale for the carb up period in a CKD.  I
have not, however, noticed any degradation in my weight training despite not
"carbing up".  Why would this be?
