Eat a good breakfast -- cereal, whole-grain breads, waffles, fruit, real juice, eggs. Don't buy snack foods and keep plenty of fresh fruit around. Where do you eat dinner? Turn off the TV. Talk to each other. The temptation is to buy prepared foods or go to a local take-out place, but both kinds of food are high in saturated fats. Many simple, nutritious meals can be put together in less than half an hour. Plan, plan, plan until it is routine. Prepare meals together and/or let your daughters take turns planning and preparing dinner at least once a week. Use these quick and healthy recipes suggested from other parents.
Encourage your daughters to continue their sports. Don't worry how hard they try -- activity is the important thing. Try to take a walk or play an active game with them every day, if only for 10 to 15 minutes. On weekends, all of you plan your meals for the coming week. Play together a lot -- walking, biking, skating -- whatever keeps all of you physically, mentally, and emotionally active.
