It really does matter what you eat, not just how much. And now, two of my favorite doctors take our collective knowledge a step further by looking at the timing of when you eat your calories: Your circadian rhythm dictates a lot more about when you should eat than you probably realize. Through clear-eyed writing and diligent research, Drs. Roizen and Crupain explain why the When Way might just be the best approach to eating.

CONTENTS
PREFACE
From Michael Roizen, M.D. (Dr. R)
Chief Wellness Officer, Cleveland Clinic
Food is powerfully evocative and has the ability to convey some of our sturdiest memories. I vividly recall, for example, the first time that five-cent hamburgers were sold in fast food joints. I also think fondly of the early advertising campaign claiming that CorningWare plates and serving dishes were indestructible. (My father promptly tried to show us how permanent it was by dropping one to the ground; it shattered, and I learned that there are exceptions to all science.)
As I embarked on my career as a doctor, I also learned about the medicinal power of food and the secrets behind proper cooking techniques. When I became dean of the College of Medicine at State University of New York Upstate Medical University, I quickly developed a curriculum that taught students how to cook healthy meals in an elective class called Culinary Medicine. We limited the class to 20 students, but 63 tried to register that first year. That was about the time I was developing my cooking expertise as part of RealAge (a system that calculates your true biological age versus your calendar age based on your lifestyle and other risk factors). I made 10 recipes a day, five days a week, for 50 weeks with a cooking partner, Donna Szymanski, and my nutritional partner, Dr. John La Puma.
I had always eaten food, of course. But that was the moment when I really found food. Through RealAge, I learned that eating well is more than just ingredients; it is also, just as crucially, about preparation and technique. You can help your body by learning to make foods you love that are also loaded with health benefits.
In my work as the chief wellness officer of the Cleveland Clinic, as well as my work with Dr. Mehmet Oz, food and food preparation have always been the foundations for giving people the power to change their lives. Jim Perko, our executive chef and culinary medicine master at the clinic, says you should never eat food that doesnt love you back. In this book, were taking it one step further by adding in the variable of time.
Im privileged to work with Dr. Michael Crupain on this methodology. Through my work as chief medical consultant to The Dr. Oz Show and his role as medical director of that program, I quickly realized that both our approaches were rooted in scienceand we had the same goals of helping people better understand food. It was a match made in the kitchen!
