IF YOUR DIET leaves you hungry all afternoon, try shifting things around. Eating most of your carbs at dinner might increase your satiety throughout the day—not to mention reduce your risk for obesity, heart disease, and diabetes.

In a recent study, published in the journal Obesity, Israeli researchers put 78 overweight police officers on one of two weight-loss diets—the first ate carbs throughout the day while the second saved them for dinner. (The study authors say the latter diet was inspired by Ramadan, during which Muslims fast all day and eat a starchy, celebratory dinner at night.)
