I can't tell you how many diet books I own. It's insane. Has one ever helped me lose weight? No. I love these kinds of books because I am a visual person. I need to actually SEE the difference in anything. I am ordering Eat This Not That: Thousands of Simple Food Swaps That Can Save You 10, 20, 30 Pounds-or More! this minute and will let you know what I think when it arrives. I know it's going to tell me I have to swap a bagel for a bialy and that is something I don't want to hear!
