Want to lose weight? You should stop counting calories

Keri Rabe, a 41-year-old elementary school librarian in Austin, Texas, used to be a hard-core calorie counter. Each day for a year, she logged everything she ate, squeezing in caloric space for twice-baked potatoes and tater tot casseroles by making them with low-fat dairy, believing fat would make her fat. She studied the menu before eating out at restaurants, choosing a dish by how many calories she had left for the day.
