It may seem strange to be writing a review of a book that, as far as I know, is out of print but I'm going to do it anyway. Eating By Design by Carrie Latt Wiatt is worth looking at if you're trying to lose weight. Psychologists will tell you that your habits are your habits because there's something about the behavior that you enjoy engaging in. Wiatt applies that principle to your eating habits to help determine why you eat what you eat.
The meat of the book is an eating personality test. When you take the test you'll probably find that you score highly on several of Wiatt's eating personality types. I suggest paying attention to all of those. For example, I scored highly as a "Passionflower", a "Soloist" and a "Lotus Eater". What does that mean? Well, a Passionflower is someone who eats for the pleasure of it. A Soloist is someone who makes food choices based on convenience. A Lotus Eater is someone who may actually have an eating disorder, compulsive overeating in my case. In short, I'm someone with a preference for food that doesn't require a lot of work to prepare or clean up after and is a pleasure to eat and I tend to eat for reasons that have nothing to do with what my body actually needs. I'm a lot more likely to be successful in following a healthy diet if I keep all of these things in mind.
Having determined your eating personality type(s), Wiatt presents you with strategies for creating a healthy diet plan that you can stick with and even provides some sample diets. I wouldn't treat this book as the only thing you need to begin eating a healthier diet but it is a good starting point.
If you're looking to lose weight I suggest visiting a used book store or perhaps the local library and seeing if you can find a copy of Eating By Design by Carrie Latt Wiatt.
