While I don't think that adopting a Paleo diet requires recognizing the validity of the evolutionary model, it did help me to recognize instantly the brilliance of Boyd Eaton's paper on Paleolithic nutrition and biological discordance. Most Paleo dieters acknowledge the importance of biological evolution, but some are creationists. Given that Paleo dieters are in such a tiny minority, I think we should learn to get along for the common good. That being said, I'll tell my story.
I am a reformed creationist. I wrote two college papers on creationism vs. evolution. In the first one I took a pro-creationist position. Further research for the second paper led me to an undecided position. This book is what tilted me to indecision and then eventually over to evolution with its brilliant refutations of creationist points:
Science on Trial: The Case for Evolution by Douglas J. Futuyma
I dare any creationist to read it without calling into question some of your assumptions and beliefs. Also influential but not mind-changing were the writings of Theodosius Dobzhansky, Ernst Mayr, Louis Leakey and others (I can't remember them all now). Creationism is now called "Intelligent Design," but the arguments haven't changed much, so don't be fooled by the slick repackaging.
"[The theory of evolution by natural selection is] the most fundamental and pervasive idea of all biology" --Loren Cordain, PhD
"Nothing in biology makes sense except in the light of evolution." -- Theodosius Dobzhansky
"[Evolution] has become the central organizing principle of modern biology, providing a unifying explanation for the diversity of life on Earth" --The Interacademy Panel on International Issues. 2006.

"Natural selection is one of the cornerstones of modern biology." --http://en.wikipedia.org/wiki/Natural_selection
"evolution is the foundation of every branch of biology; in fact, it is so fundamental and pervasive that we often take its importance for granted. ..."
