The best way to cut calories on your meal out, is to eat in. Make whole wheat spaghetti and enjoy your night Lady and the Tramp style. Cooking at home, where you can control your portion sizes and the amount of butter used will save hundreds of calories (and dollars). If you must eat out, start with a soup or salad and skip the bread basket. Choose one course to be your indulgence and be calorie-smart about the rest of the meal.
