WHAT TO EAT WHEN A STRATEGIC PLAN TO HACK YOUR METABOLISM DRS. MIKE ROIZEN AND MICHAEL CRUPAIN TAP INTO THE LATEST RESEARCH ON OUR BIOLOGICAL CLOCK TO OPTIMIZE HEALTH AND WEIGHT LOSS IN THEIR NEW BOOK Dr. Michael Roizen and Dr. Michael Crupain - the two doctors I always turn to for the latest scientific discoveries - prove that timing really is everything in this insightful, fun, and revolutionary book. What to Eat When show[s] that when you eat is just as important as what you eat - and reveals the right foods for life's toughest circumstances. -Dr. Mehmet Oz
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. -Dr. Sanjay Gupta
When we think about eating, we focus - as we should - on the quality and quantity of what we eat. It's becoming clear that we also need to think about chronology - when we eat. Drs. Roizen and Crupain's fun and revealing exploration of the biology of timing and eating will help you eat the way your body really wants you to. -Dr. Andrew Weil
WHAT TO EAT WHEN: A Strategic Plan to Improve Your Health and Life Through Food (National Geographic Books; on sale Dec. 31, 2018; ISBN: 978-1-4262-2011-1), is a groundbreaking new book about the science of nutrition timing, co-authored and researched by best-selling author Michael Roizen, M.D., and preventive medicine specialist Michael Crupain, M.D. The two doctors give readers an inside look at the schedule underlying our body's metabolism and reveal why the time on the clock matters as much as what's on the plate. The book provides new research-based guidelines on how to adjust our diets to align when we eat with our biological clock and shows that eating The When Way can help us optimize health, increase energy and lose weight. In addition to their easy-to-remember health principles, Roizen and Crupain offer a straightforward 31-Day Plan of Action and delicious food-based solutions to life's daily challenges.
You've been probably told to count calories, eat low fat, high fat, low carb or high carb, and most of the time the results don't last and then we fail and blame ourselves. So, we decided it was time to ask a different question: not What should we eat?' but WHEN should we eat?' says Roizen, who is chief wellness officer at the Cleveland Clinic.
The doctors' science-backed advice flips diet dogma on its head (for example, eat your dinner for breakfast, don't avoid carbs and stop counting calories), and gives us hacks to eat our favorite types of food and still lose weight.
It turns out that when you eat is as important as what you eat, says Crupain, chief of the Medical Unit at The Dr. Oz Show. This is groundbreaking, because throughout the day your metabolism is changing based on your internal clock - called your circadian rhythm. By aligning what you eat, with WHEN your circadian rhythm is expecting certain foods, you can take full advantage of your metabolism to maximize health and weight loss.
In this trailblazing book, Roizen and Crupain assert that food truly is medicine, and explain how to eat it for both health and taste. Of course, no day is perfect or even the same as the last, so the two Dr. Mikes provide 30 short chapters on situational eating that reveal the best way to eat no matter what life throws at you, including:
When you're stressed or anxious
When you're tired or hangry
When you're pregnant or nursing
When you're at a party
When you're exercising
When you have a family history of heart disease
When you have digestive distress
When you have a family history of cancer
As it happens, the doctors not only spend their time working with patients and populations to improve their health and wellness, but they are also passionate cooks who love good food and want you to love what you eat. WHAT TO EAT WHEN is not a diet book but a powerful guide that will help us rethink what and when we eat in order to lead healthier, longer lives.
