You've heard to make breakfast the biggest meal of your day, but you may not be that hungry when you wake up. In fact, "your biggest meal should be around noon when your digestion is at its peak and you can feed your body when it actually needs fuel," says Dr. Lipman. That means you don't need a huge meal at dinner only to sit and catch up on True Detective and then go to bed. But "big" doesn't mean burger and fry big. At lunch, emphasize protein and greens, like a hearty bowl of lentil soup and kale salad. Another bonus: after dinner you won't have the feeling you need to unbutton your pants.
Fasting indeed has a long-standing spiritual tradition. "Almost every religion has some type of fasting ritual -- Lent, Ramadan, Yom Kippur ... the Hindus and Buddhists fast, too," says James Dillard, MD, assistant clinical professor at Columbia University College of Physicians and Surgeons in New York City. He's author of Alternative Medicinefor Dummies.
