There are many books to get you started. "Inner winds" mentioned a great and more recent one "Hip Chick's Guide To Macrobiotics" by Jessica Porter. A good basic introductory book written in the 1980s is "The Macrobiotic Way" by Michio Kushi.
I am developing a new website under my name as an online resource for macrobiotics. Currently I host live free conference calls that I am calling "Macrobiotic Miracles" featuring guest speakers who have been able to transform their lives.
Manya - On my site I am planning to address questions concerning Macrobiotic Counselors and Counseling. If you (or anyone) has a specific question then feel free to message me on here or through Facebook ( http://www.facebook.com/Phiya )
Alicia totally inspired me to dig into Macrobiotics as well! I found a couple of fun books I enjoyed as well: Hip Chick's Guide to Macrobiotics (Jessica is amazing and hilarious) and Mayumi's Kitchen, which offers macrobiotic recipes inspired by world cuisine and is written by Madonna's former personal chef.
I checked out a bunch of other macrobiotic books from the library, but I was most interested in simple, fun recipes and less interested in books about the philosophy.
Another thing I really love about macrobiotics is the idea of soaking and cooking any dried beans with Kombu - really helps cut down on the gas. Alicia's beans and squash and her arame with carrots and onions in The Kind Diet really got me macrobiotic eating.
