WHAT TO EAT WHEN

What if drinking a kale-infused smoothie could counteract missing an hour's worth of sleep? When is the right time of day to eat that chocolate chip cookie? And would you actually drink that glass of water if it meant skipping the gym? This revolutionary guide reveals how to use food to enhance our personal and professional lives - and increase longevity to boot. What to Eat When is not a diet book. Instead, acclaimed internist Michael Roizen and certified physician Michael Crupain offer readers choices that benefit them most - whether it's meals to help them look and feel younger or snacks that prevent diseases - based on the science that governs them.
