I have read this book and applied some of the suggestions to my daily diet. Now when I grocery shop I make sure to read my food labels very carefully. Just because a loaf of bread claims to be wheat bread on the front of the packaging doesn't mean this is 100% true. I now look for fewer ingredients that are listed on my food labels. I try to purchase higher quality ingredients as well. My stomach always feel bloated and at times I feel lethargic. I know the symptoms I am having are attributed to certain foods I consume. Since applying some of the tips in this book on a daily basis, my stomach no longer feels bloated and I feel less lethargic. I have lost several pounds and my sinus is less of a bother too me. This book is very easy to use in my opinion. You have to be willing and opened minded to give this plan a try. I have also purchased the Wheat Belly Cookbook to have recipes to refer to when planning some of my meals.
