How's this for a "diet": You don't swear off a single food. Instead, eat a smidge less every day and eat at home a little more. That's what we call "happy eating."
Leave two bites at every meal.
"Literally continue to eat exactly what you have been, except forgo a couple of forkfuls at every meal," says James Hill, Ph.D., director of the Center for Human Nutrition at the University of Colorado, in Denver. "I guarantee you won't be hungry, and you'll cut out about 100 calories a day from your diet." So don't finish all of that blueberry muffin at breakfast, throw out the crust of your pizza at lunch, and clear the dinner table with a strip of chicken and a spoonful of rice still on your plate. By the end of the week you'll have saved 700 calories. Keep it up and you'll avoid those 1 or 2 pounds that most Americans gain each year.
