If you are a vegan, vegetarian, or just a person looking to add more soy into your diet because of the health benefits you've heard about--oh yeah, and you're interested in the Zone way of eating--get this book. One more thing--bypass Sears' frist book "Enter the Zone." First of all, "Enter the Zone" is only offerred in hardback...uh, it's been out for amost 10 years now, so I think a paperback is warranted. Much of "Enter the Zone" is about how fabulous Barry Sears is and how his diet has worked for all these olympic level atheletes--great! But certainly not me. "The Soy Zone," on the other hand, includes all of the important information from "Enter the Zone," including how to calculate your lean body mass in order to figure out your protein needs, and once you've got that, you can figure out how many blocks of protein you need to consume--the basis of the Zone diet. "The Soy Zone" also goes into detail about how the Zone works by regulating insulin and glucagon levels, and everything else you'd need to know--without the self-aggrandizing. And it's in paperback! Wahoo! The recipes offer an easy way to add soy into your diet if you are not a vegetarian/vegan, and if you are a vegetarian/vegan, the recipes show you how to beef up (er, soy up) the amount of protein in your food.
