When we eat may be as important as what we eat. Discover how to align your lifestyle with your body's natural clock for better overall health--from an award-winning circadian rhythm and aging researcher. "A complete program to recalibrate your day/night activities, optimize sleep, lose weight, learn/work, and exercise."--Valter Longo, PhD, internationally bestselling author of The Longevity Diet Most people typically wake up, get hungry for meals, and doze off in bed around the same time every day. But if you've ever experienced jet lag or pulled an all-nighter, you know that this schedule can easily be thrown off kilter. For some people, that imbalance--difficulty sleeping at night, hunger at odd times, or sudden fatigue at noon--is a constant. Dr. Satchin Panda, one of the leading researchers on circadian rhythms, has a plan to reset your body clock. Beginning with an in-depth explanation of the circadian clock--why it's important, how it works, and how to know it isn't working--The Circadian Code outlines lifestyle changes to make to get back on track. It's a concrete plan to enhance weight loss, improve sleep, optimize exercise, and manage technology so that it doesn't interfere with your body's natural rhythm. Dr. Panda's life-changing methods show you the keys to avoiding and alleviating chronic ailments like diabetes, cancer, and dementia, as well as digestive conditions like acid reflux, heartburn, and irritable bowel disease. In short, knowing your circadian code might just be the secret to turning back the clock and slowing down the aging process.
