I have very mixed feelings about this book. As noted in the other reviews, it is written from a religious point of view. I am an atheist, but I didn't see this as a reason not to read this book. I was amused by the author's comments that if "non-believers" have been able to do this, you'll be even better at it because God is helping you!
I also realized while reading I also have a lot more experience than most with nutrition and healthy eating. However, there's always room for improvement, which is why I sought this out. I grew up in a home where my mom made every meal from scratch and we had a vegetable garden. I took an excellent nutrition class in college. At some point, I saw a documentary on Dr. Roy Wolford, Biosphere 2, and calorie restriction/optimal nutrition. In late 2011/early 2012, I read bodybuilding nutrition books, and started tracking my nutrition and calories daily for several months. I experimented with healthy meals, would enter my food and then check where I was low on the nutrition, enter it into my excel spreadsheet and research foods (nutrition and calories from the USDA database) to figure out which were the most nutritious and lowest in calories. The research and recording ended up taking me about 4 hours a day. I got my nutrition up to about 97% per day, which you can't really do without tracking it.
I've kept up that eating plan for the most part over the last 10+ years. I say all of this because I went into reading this book with quite a bit of knowledge on nutrition, and I was looking for something else out of this book, which offers little info on nutrition and specific foods to eat. My current problem is eating too much junk food and treats (while mostly maintaining my nutrition level), and I eat those things for pleasure and comfort.
A couple of years ago, I had gotten to a point where I wasn't regularly eating any junk or candy and I was happy with it. I happily tossed out the leftover candy I'd bought for trick-or-treaters. Then, I got invited to a Christmas cookie exchange, and once I'd made those favorites, I had to keep and eat some, and it triggered months of overeating chocolate, cookies, and other treats. Ever since, I've been struggling on and off to cut down on those things.
I agree with another reviewer that the wife probably should have written this book instead of the husband, since she seemed to have a lot more to offer and was a lot more practical. I felt the husband's approach to eating was shaming, and I found the portrayal of women as tempting seductresses (readily available outside objects rather than fully human individuals) offensive. I also found the section with the Bible quotations boring.
With all of that said, I really liked the theme of completely cutting out certain unhealthy foods and not just eating them in moderation ("just enough to keep those addictions alive"). I have completely cut out certain foods over the years, and it might seem silly but it never occurred to me to completely cut out things like chocolate, cake, dessert, etc. I never drink alcohol, do drugs, or eat breakfast cereal (lol), so I do believe now it's possible to cut out these things as well.
I'd always subscribed to a "cheat day" philosophy for food, but I have a difficult time drawing the line and getting back on track the next day, so this idea has given me a lot of food for thought. I do think it is going to be life-changing for me. I would recommend this book for anyone who is having a hard time saying no to tempting foods who doesn't need info on nutrition or help with what foods to eat.
