Yes, again we have to recognize that there is little reason to
believe that a "typical" paleodiet is/was ketogenic.
Furthermore, while ketosis may slow the growth of some tumors
(not all tumors) I am not aware of any evidence that it cures
them. Obviously what we want is not slower tumors but no cancer
at all. The Kitava diet probably has a favorable ratio of w-6 to
w-3 fats, and an unfavorable ratio is beginning to be recognized
as a risk factor for cancer. The absence of grains is probably a
help for the Kitava as well. Not only are most grains high in
w-6 but of course they also may contain carcinogenic lectins.
