I haven't read the book but, I did read an article on it and I believe it! I wasn't on the fertility diet when I got pregnant but, I was on my 2nd week of the South Beach. My sister also started really watching her diet and got pregnant right away and another friend of mine got pregnant her 2nd week of the South Beach. So, I think it does make a big difference. Also, if you are TTC, make sure you're taking a folic acid supplement everyday.
