Myth #1: As Long As You’re Eating Healthy Foods, Calories Don’t Matter.
Truth: Not necessarily. Whole-wheat pasta (or bread or, um, pie crust) has just as many calories as “regular.” Same goes for brown and white rice. Avocados, nuts and olive oil deliver heart-healthy fats—and significant calories. Red wine and dark chocolate are full of antioxidants, but if you indulge every day without accounting for their calories, you’re likely to gain weight. Upshot: Pay close attention to calorie counts of all foods (OK, maybe not plain steamed broccoli) so that “health halos” don’t lead your eating astray.
