If you want to control your weight, eat at home more often. Women who ate in restaurants more than five times a week consumed almost 300 more calories a day than did those who dined out less, a University of Memphis study found. Done consistently, that could mean gaining more than 2 pounds a month. Smart dining tips: Refuse the bread basket, order appetizers instead of entrees, ask for grilled and baked dishes, request dressings and sauces on the side and split large portions, especially desserts.
