I just finished the book Grain Brain by Dr. David Perlmutter, a neurologist and Fellow of the American College of Nutrition.
An alternate title for this book could have been “How to Lose Your Taste For Sugar and Bread”. When you understand what goes on in your body when these foods are a regular part of your diet, suddenly that muffin or bagel for breakfast doesn’t look so tasty anymore. It’s sort of like going to a dinner party and drooling over the cheesecake they’ve got on display that will be served for dessert, but then someone whispers in your ear that the chef mixed a laxative into the batter because she’s ticked off at the host. Amazingly, you now have no urge to eat any cheesecake, no willpower needed.
